Door Alarm Sensors Posts

Last week, we took a look at three of the best alarm panels in the industry. These were the Honeywell Lyric, the Qolsys IQ Panel 2 Plus, and the 2GIG GC3e. Today, we are checking out the sensors that you can add to support these systems. Here is our 2020 Security Sensor Buying Guide!

Sensors are accessories that are added to alarm systems to report specific activity. Each sensor has its own job of looking for a certain type of activity in its designated location. All of the sensors on a system communicate with a single centralized panel or hub. This panel is actively listening for any sensor that is triggered due to a potentially important system event. Adding new sensors is perhaps the best way to expand upon an existing system, and they make awesome gifts and stocking stuffers for the security enthusiast in your life.

Broadly speaking, sensors can be split into two main categories, which are security and life safety/environmental. Security sensors look for activity that suggests potentially unauthorized entry into a monitored and protected location, such as a door being opened, movement in a room where nobody is supposed to be present, or a window being broken. Life safety/environmental sensors look for activity associated with unwanted or potentially harmful conditions that affect the well-being of those in the area, such as a flood, an extreme temperature, a fire, or the presence of CO gas. We'll be taking a look at life safety/environmental sensors another time. Today, our focus is on security sensors.

Wireless Sensor Basics

Before we dive into specific security sensors for our top panel picks, we're going to start by giving you some general, generic information that can be applied to any sensor out there. First, understand that this post is focusing only on wireless sensors. These are almost always the sensors chosen for use with wireless alarm systems. Wired sensors can also technically be used with wireless panels but a converter module is almost always needed. Not to mention the fact that wireless sensors are significantly easier to install, especially for DIY users. The only time you will realistically see wired sensors used with a wireless panel is if a user is upgrading from an older wired system and bringing over their old wired sensors, or in new construction where a user wants to integrate the sensors in with the building. But if you're expanding upon a wireless system by getting new sensors, then the new sensors will almost certainly be wireless.

The important thing to remember when choosing wireless sensors for a wireless alarm panel is making sure the sensor is compatible with the system. It doesn't matter if a sensor has all the specs and features if it doesn't work with your panel! The way to determine compatibility is to look at the lineup that the sensor is from. Petty much every wireless sensor out there is part of a larger grouping of sensors that will all have the same compatibility.

To make it easier for you, we have the three panels we mentioned before (well, make that five, as the Qolsys IQ Panel 2 Plus actually comes in three versions), and all their compatible sensor lineups conveniently listed. We hope that this sheds some light on your options. The only caveat is that for any panel listed here that supports the Honeywell 5800 Sensors, we must be clear that this is only for the uni-directional sensors with one-way communication in the lineup. Any bi-directional Honeywell 5800 Sensors with two-way communication will not work with any of the aforementioned systems. The bi-directional Honeywell 5800 Sensors are only compatible with the Honeywell LYNX Touch and VISTA Systems, which were not included in our buying guides.

With that out of the way, here are compatible sensor lineups by system:

• Honeywell Lyric - Honeywell SiX Series, Honeywell 5800 Series, 2GIG 345 MHz Series
• 2GIG GC3e - 2GIG eSeries Encrypted Sensors, 2GIG 345 MHz Series, Honeywell 5800 Series
• Qolsys IQ Panel 2 Plus 319.5 MHz - DSC PowerG Sensors, Qolsys S-Line Sensors, Qolsys Legacy 319.5 MHz Sensors, Legacy Interlogix Sensors, Legacy GE Sensors
• Qolsys IQ Panel 2 Plus 345 MHz - DSC PowerG Sensors, Honeywell 5800 Sensors, 2GIG 345 MHz Sensors
• Qolsys IQ Panel 2 Plus 433 MHz - DSC PowerG Sensors, Legacy DSC 433 MHZ Sensors

You will notice that some of the sensor groups listed above are italicized and underlined. That is done to identify the lineups of encrypted sensors. These encrypted sensors have special protection measures put in place to make them more secure and less prone to being hacked or defeated by malicious attacks. Encrypted sensors tend to have more restricted compatibility. They may follow a special enrollment process. Encrypted sensors often use bi-directional communication so that the sensor knows that it is actively paired with the system. Many encrypted sensors may only be paired with a single system at any given time, and the sensor will need to be deleted from its existing system before it will work with a new one.

It's okay to use non-encrypted sensors with your system, especially in zones that are less likely to trigger an alarm, like a second story window. Many users will opt to use a mixture of both encrypted and non-encrypted sensors. Other users feel comfortable using entirely non-encrypted sensors. It really comes down to your level of comfort. Non-encrypted sensors are secure in most situations, and they are still tricky to defeat. But going fully encrypted is recommended for anyone seeking maximum security. One tip if you do decide to go with some non-encrypted sensors is to avoid letting others know what wireless frequency your sensors use or what type of system you have installed. Knowing the frequency and the system being used makes it much easier for a savvy intruder to defeat a sensor.

Door & Window Alarm Sensors

Now that you know some basics that apply to almost all wireless sensors, let's start talking about specific types and models. Door and window sensors will let a system know when a door or window has been opened or closed. These are some of the most basic and easy to use sensors on a security system. These devices work by using a larger sensor portion and a smaller magnet portion. The sensor is placed on or inside the door or window frame, and the magnet is placed on or inside the moving portion of the door or window. When the door or window is opened, the magnet will move away from the sensor. This will trip a metal reed switch inside the sensor, which will tell the sensor to alert the system to the opened door or window. All of the sensors we've listed here follow that same method of operation.

Door and window sensors can be split into two (2) main categories. Surface-mount door and window sensors are mounted outside the door or window and its accompanying frame on the surface. The advantage to surface-mount door and window sensors is that they are very easy to install, and they can usually be mounted using double sided foam tape. But some users may not like how they are visible on the outside of the door or window. If you don't like the appearance of visible surface-mount door and window sensors, then you might instead consider recessed door and window sensors. A recessed door or window sensor is installed inside a door or window and its frame, so that it is hidden and cannot be seen from the outside. Recessed door and window sensors are more difficult and time-consuming to install, because you must drill holes in both the door or window and its accompanying frame. Whether you decide to use surface-mount door and window sensors, or recessed door and window sensors is up to you. Most DIY users and Alarm Grid customers in general will use surface-mount door and window sensors.

Now let's look at some door and window sensors.:

Motion Sensors

Motion sensors use passive infrared (PIR) technology to detect movement within the sensor's coverage area. This is done by looking for the changes in infrared (IR) energy that occur when a person, animal, or object comes within the sensor's field of view. Standard motion sensors are typically PIR only. These are appropriately called PIR motion sensors.

Some motion sensors will also use microwave technology in addition to PIR technology. This involves having the sensor send out microwave signals and seeing how the signals bounce off of objects in the area. Movement will change the pattern of these microwave signals, and the sensor will be able to detect this. These motion sensors that use both microwave and PIR are called Dual-Tech motion sensors. The purpose of using both PIR and microwave together is to prevent false alarms. A Dual-Tech motion sensor will only activate and alert the system if both its PIR sensor and its microwave sensor are triggered. A microwave sensor is not vulnerable to the same environmental issues that may cause a false activation on a PIR. You will not find a motion sensor that uses microwave technology without PIR detection, as microwave alone would result in too many false alarms without having PIR to confirm movement.

One feature that you will often see listed on a motion sensor is pet-immunity. A motion sensor that has been set up for pet immunity can be configured to not "look" in the areas close to the ground where pets and small animals walk. Instead, the motion sensor only looks in the areas higher up, where humans move while walking upright. A pet immune motion sensor is not impervious to small animals, and you must position it carefully so that it works as intended. Pet immune motion sensors normally have a weight limit, where animals under that weight limit should avoid triggering the sensor, assuming that the sensor is installed properly. Please note that most pet friendly motion sensors will require you to set the sensitivity for the sensor to the lowest possible setting.

When it comes to motion sensors, mounting them carefully is very important. A motion sensor may cause false alarms on the system if it is not installed properly. These sensors should not be facing any vents, air ducts, ceiling fans, or curtains that may cause the sensor to activate without any movement. If you are using the motion sensor for pet immunity, then it should also not be facing any furniture or stairwells that your pet could use to get within the sensor's field of view. You will likely want to perform a Walk Test of your motion sensor to make sure that it responds properly when movement is present, and does not respond due to other external factors when there is no movement. You should also have any pets participate in the Walk Test to ensure that pet immunity is working properly.

We recommend reading the following FAQs to learn more about motion sensors:

Glass Break Sensors

The last type of security sensors we will be discussing are glass break sensors. These sensors include built-in microphones, and they actively listen for the unique sound of glass breaking. Most of these sensors will need to hear both the high-pitched shattering sound of the glass breaking, as well as the low-pitched sound of an object striking against the glass in order to activate. This design choice is to prevent false alarms caused by similar sounds. Most users will use glass break sensors to monitor windows, but they have also been known to work effectively on protective glass display cases that store valuables, such as what you might find in jewelry stores or gun shops. Most types of glass will work with glass break sensors, though there are some exceptions. For example double and triple pane glass windows won't work reliably. The same is true for coated or "safety" glass. Refer to the manual for the exact glass break detector you are using to determine compatibility.

A single glass break detector can monitor multiple windows or display cases, as long as the glass it is monitoring is within its detection range, which is typically 15 to 25 feet. Any glass that is being monitored must have a direct line of sight with the sensor, with no obstacles blocking the path that sound will travel through. When testing your glass break sensors, it is strongly recommended that you us a glass break simulator. These devices will mimic the sound of the glass breaking and activate your glass break sensors without actually breaking any glass. Remember to refer the instructions of your glass break simulator for more information. When choosing a glass break simulator, it is best to use a simulator from the same manufacturer, if possible. We have a Honeywell Glass Break Simulator and a DSC Glass Break Simulator available on our website. If you get one of the 2GIG Glass Break Sensors mentioned in this buying guide, then the Honeywell Glass Break Simulator is best for testing. Otherwise, just match the manufacturer.

Door & Window Alarm Sensors

Now that you know some basics that apply to almost all wireless sensors, let's start talking about specific types and models. Door and window sensors will let a system know when a door or window has been opened or closed. These are some of the most basic and easy to use sensors on a security system. These devices work by using a larger sensor portion and a smaller magnet portion. The sensor is placed on or inside the door or window frame, and the magnet is placed on or inside the moving portion of the door or window. When the door or window is opened, the magnet will move away from the sensor. This will trip a metal reed switch inside the sensor, which will tell the sensor to alert the system to the opened door or window. All of the sensors we've listed here follow that same method of operation.

Door and window sensors can be split into two (2) main categories. Surface-mount door and window sensors are mounted outside the door or window and its accompanying frame on the surface. The advantage to surface-mount door and window sensors is that they are very easy to install, and they can usually be mounted using double sided foam tape.

Whether you decide to use surface-mount door and window sensors, or recessed door and window sensors is up to you. Most DIY users and Alarm Grid customers in general will use surface-mount door and window sensors.

You will likely want to perform a Walk Test of your motion sensor to make sure that it responds properly when movement is present, and does not respond due to other external factors when there is no movement. You should also have any pets participate in the Walk Test to ensure that pet immunity is working properly.

Glass Break Sensors

The last type of security sensors we will be discussing are glass break sensors. These sensors include built-in microphones, and they actively listen for the unique sound of glass breaking. Most of these sensors will need to hear both the high-pitched shattering sound of the glass breaking, as well as the low-pitched sound of an object striking against the glass in order to activate. This design choice is to prevent false alarms caused by similar sounds. Most users will use glass break sensors to monitor windows, but they have also been known to work effectively on protective glass display cases that store valuables, such as what you might find in jewelry stores or gun shops. Most types of glass will work with glass break sensors, though there are some exceptions. For example double and triple pane glass windows won't work reliably. The same is true for coated or "safety" glass. Refer to the manual for the exact glass break detector you are using to determine compatibility.

A single glass break detector can monitor multiple windows or display cases, as long as the glass it is monitoring is within its detection range, which is typically 15 to 25 feet. Any glass that is being monitored must have a direct line of sight with the sensor, with no obstacles blocking the path that sound will travel through. When testing your glass break sensors, it is strongly recommended that you us a glass break simulator. These devices will mimic the sound of the glass breaking and activate your glass break sensors without actually breaking any glass. Remember to refer the instructions of your glass break simulator for more information. When choosing a glass break simulator, it is best to use a simulator from the same manufacturer, if possible. We have a Honeywell Glass Break Simulator and a DSC Glass Break Simulator available on our website. If you get one of the 2GIG Glass Break Sensors mentioned in this buying guide, then the Honeywell Glass Break Simulator is best for testing. Otherwise, just match the manufacturer.

If you're setting up a new security system for use with Alarm.com, then you might be wondering which door and window sensors to use. The answer really comes down to which system you are using and how you intend on using your sensors. Plenty of contact sensor options are usually available!

Alarm sensors do not communicate directly with Alarm.com. Instead, sensors communicate with alarm panels. From there, the panel will use an alarm monitoring communicator to send signals to Alarm.com. This communicator must be activated and registered for Alarm.com service. Per Alarm.com requirements, cellular connectivity is required. This means that your system must use a cellular communicator or a dual-path communicator that is built for use with Alarm.com.

As far as choosing specific sensors, it comes down to determining whether or not they will work with the system you are intending to use with Alarm.com. Today, we're going to break down some of the most popular Alarm.com Security Systems and help you determine the best sensors to use. Remember that our security system kits already come with some compatible sensors to get started. It may only be that you just need to add a few more door and window sensors, or you might not need to add any extra ones at all!

We will give you three (3) scenarios for each system. These are:

1. Surface-Mounted Door/Window Sensors
2. Recessed Door/Window Sensors
3. Outdoor Door/Window Sensors

In most situations, surface-mounted sensors are what you want to go with. These are the standard regular sensors that you would use with virtually any door or window. They are super easy to install, and they are some of the most basic security devices you will encounter.

If appearance is important to you, and you want the sensor to remain hidden while the door or window is closed, then you may consider getting recessed sensors instead. Just remember that recessed sensors will require you rolling up your sleeves and drilling holes into your door/window and its frame. In addition to the added work, this may also have warranty ramifications with regard to the door or window.

And of course, if you plan on using the door/window sensor in an outdoor environment, then you will want to make sure the sensor is approved for outdoor use. Trying to use an indoor-only sensor in an outdoor environment will likely result in damage to the device due to exposure to rain, dust, etc. This also typically applies if you plan on using the sensor in an area that is not insulated, such as a shed, a gate or a barn.

Note: If you are totally new to door and window sensors and want to know more about how they operate, please check out this FAQ.

Qolsys IQ Panel 2 Plus (PowerG)

Arguably the most popular system to use with Alarm.com right now in 2020 is the Qolsys IQ Panel 2 Plus. There are three (3) versions of the system, with each one supporting a different legacy sensor frequency (319.5 MHz, 345 MHz, 433 MHz). We will discuss the legacy sensor options in a minute. But one of the biggest reasons to purchase an IQ Panel 2 Plus is to use PowerG Sensors. All three versions of the Qolsys IQ Panel 2 Plus support the PowerG Sensors. These sensors can communicate with the IQ Panel 2 Plus System from up to 2,000 feet away in open air, and they utilize 128-bit AES encryption and frequency hopping spread spectrum (FHSS) for enhanced wireless security. For anyone with an IQ Panel 2 Plus, these are the sensors we would point to first.

• Surface-Mounted Sensor: DSC PG9303
• Recessed Sensor: DSC PG9307
• Outdoor Sensor: DSC PG9312

2GIG GC3e & 2GIG GC2e (eSeries)

Right now, we view the 2GIG GC3e and the 2GIG GC2e as the best alternatives for users who want to get started with Alarm.com, but don't want to use a Qolsys IQ Panel 2 Plus. The most popular sensors to use with these systems are the encrypted 2GIG eSeries Sensors. They are built for the GC3e and GC2e Systems, and they utilize encryption for protection against wireless hacking or takeover attempts. Remember that these systems are both backwards compatible with 345 MHz sensors (more on those later). But if you're running a GC3e or a GC2e, then we're going to recommend the eSeries products.

• Surface-Mounted Sensor: 2GIG DW10e
• Recessed Sensor: 2GIG DW20e
• Outdoor Sensor: 2GIG DW30e

Original Qolsys IQ Panel 2, IQ Panel, Interlogix Simon Systems (Legacy 319.5 MHz)

Things become a little tricky when we get into the legacy sensor frequencies. There is usually a lot of inter-compatibility across manufacturers, so often the choice comes down to preference. We will list our favorites based on value and functionality. But understand that you have a lot of options available when it comes to 319.5 MHz sensors. This frequency is used with the original Qolsys IQ Panel 2, the original Qolsys IQ Panel, and all of the legacy Interlogix Simon Series Panels. Keep in mind that you can also use these sensors with the 319.5 MHz version of the IQ Panel 2 Plus as an alternative to PowerG. The 319.5 MHz frequency is also typically used with any wired Interlogix NetworX Panel that has a wireless receiver added.

• Surface-Mounted Sensor: VERSA-GE
• Recessed Sensor: Qolsys IQ Recessed Door-S
• Outdoor Sensor: ELK 319DG

2GIG GC3 & 2GIG GC2 (Legacy 345 MHz)

If you are working with a 2GIG GC3 or a 2GIG Go!Control GC2, then you will be enrolling legacy 345 MHz sensors with your system. This frequency was popularized by the Honeywell 5800 Sensors, and later the 2GIG 345 MHz Sensors. The GC2 and GC3 support both of these lineups, so you really have a lot of options to choose from. We're just going to list our particular favorites. Remember that you can also use these sensors with a 345 MHz IQ Panel 2 Plus as an alternative to PowerG.

• Surface-Mounted Sensor: VERSA-2GIG
• Recessed Sensor: 2GIG GW20R
• Outdoor Sensor: 2GIG DW30-345

DSC Impassa & DSC PowerSeries (Legacy 433 MHz)

DSC popularized their own wireless frequency of 433 MHz. If you have a DSC Impassa, then these will be the sensors you are using. The 433 MHz sensors can also be used with a DSC PowerSeries Panel that has a wireless receiver added. Although we do not sell the original DSC PowerSeries Systems, we do offer the DSC RF5132-433 Wireless Receiver that will allow support for these sensors. And of course, you can also use these 433 MHz sensors with the 433 MHz version of the IQ Panel 2 Plus as an alternative to PowerG. Unfortunately, we don't have a good recommendation for a 433 MHz outdoor door and window sensor. so we'll just list the other two types instead.

• Surface-Mounted Sensor: VERSA-DSC
  
• Recessed Sensor: DSC EV-DW4917
  

Honeywell VISTA, DSC PowerSeries, DSC PowerSeries NEO, Interlogix/GE NetworX (Wired Sensors)

Many hardwired security systems can connect with Alarm.com using what is known as an Alarm.com System Enhancement Module (SEM). And since hardwired panels often use wired sensors, this makes hardwired door and window contacts technically compatible with Alarm.com as well! Honeywell VISTA Systems, DSC PowerSeries Systems, DSC PowerSeries NEO Systems, and Interlogix/GE NetworX Systems all have compatible SEM communicators available.

The great thing about hardwired contacts is that they are pretty much universal across all wired systems, provided that the system is not using polling loop sensors. We'll focus on standard non-polling loop sensors here, but these are all good options for most hardwired alarm panels. Also keep in mind that there are MANY options when it comes to wired contacts. Don't feel like you are restricted to the ones we happened to pick!

Hi DIYers! We're here with another Alarm Grid Tip. We're going to cover the proper technique for mounting your door alarm sensors. Many people have trouble getting a faulted zone to disappear when their sensors are not aligned properly. Mounting your sensors correctly will fix this issue.

First, It's important to understand how door and window contacts work. There are two (2) parts. These are a sensor and a magnet. The sensor is the larger component and usually represents the listed product dimensions. The magnet is the smaller component. In a proper installation, the sensor (larger) should be mounted on the door frame. The magnet (smaller) should be mounted on the actual door. Ideally, the magnet and the sensor should be in direct contact when the door is closed. The magnet should also be aligned with the metal reed switch inside the sensor. The sensor will most likely have indentations to indicate the location of the reed switch.

The idea is that when the door is closed, the magnet will be in contact with the sensor. This is why these sensors are often called "contacts". When the door is opened, the magnet will become separated from the sensor. This will release its internal metal reed switch. When this happens, the sensor will transmit a signal to the alarm control panel. The system will respond based on the programming settings for the corresponding zone.

When you mount your door contacts, you should make sure that the magnet and the sensor are in proper alignment when the door is closed. If not, then the reed switch inside the sensor will stay open. As a result, the zone will still be shown as faulted on the panel. You want proper alignment so that the zone functions consistently. Whenever the door is opened, the zone should appear as faulted. If it's closed, then you should not see any faults.

Walk testing your contacts is extremely important! This is the best way to make sure that the sensor and magnet are in proper alignment. Sure, it might pass the eyeball test, but does it pass the system test? Always, always, always test your equipment! We don't care if you are a novice DIYer or a seasoned professional installer - your job is not finished until you have completed the walk test.

Again, the ideal door sensor and magnet will be IN DIRECT CONTACT when the door is closed. This will provide the best possible results. We have seen customers stack multiple pieces of double-sided foam tape to make this happen. This is pretty unusual, but it works! It might look funny if you have to do that, but it will get the job done! As long as the sensor and magnet are in correct alignment, then the sensor will work.

If you absolutely must leave the contact and magnet separated, do not do so from more than one-half (0.5) of an inch, unless the manual specifically says that the sensor-magnet gap can be further. And make sure to test extra thoroughly if you decide to try and get these sensors to work with a wider magnet spacing.

Also remember to check sensor for indentations that indicate which side to place the magnet. If you are unsure, then check the device manual. Many answers can be found in the installation instructions. Unfortunately, many end users choose to ignore them. Read the manual!

Keep in mind that some door sensors may be equipped with LED lights that help the installer make sure that the sensor and magnet are indeed in proper alignment. If your sensor has this feature, then definitely use it! This is an easy and convenient way to make sure they are aligned correctly. Check your device manual for more information. An example of a door sensor that is equipped with this feature is the Honeywell 5800MINI.

Below is an example of what a properly installed contact looks like. In this case, it is the 2GIG DW10. Note how the sensor and the magnet are in direct contact and properly aligned. Normally, the battery tab at the bottom of the sensor would be removed, but for this example, it's okay.

We hope this tip has been helpful for anyone setting up their first alarm system. Please email us at support@alarmgrid.com if you have any questions. We look forward to hearing from you!

Door contacts represent some of the most popular sensors that are used with alarm systems. Nearly every setup will incorporate these devices in some form. After all, knowing when a door has been opened is critical for most systems. But there is a lot to consider when choosing door contacts.

A door sensor is a device that is used to let an alarm control panel know when a door has been opened. When this happens, the system will respond depending on panel's current arming state and the programming settings for the zone. Some popular responses for door contacts include requiring a system disarm within the entry delay period, producing a simple chime and triggering an immediate alarm. These responses are present with virtually any door contact and system setup. A previous blog post of ours actually covers the Response Types for door sensors in greater detail. We recommend checking out that post for more information. But while the general functionality is the same across almost any contact, selecting the best option for your system might seem overwhelming.

Perhaps the first thing you should consider is whether you want a hardwired contact or a wireless contact. A wired contact will communicate with the panel through a direct hardwired connection. A wireless contact will communicate with the panel through wireless RF signals. The advantage to a wireless sensor is that it will be much easier to set up, since no wires will need to be run from the system to the sensor. But some users prefer hardwired sensors, as they essentially become a fixture for the building itself. Another advantage to hardwired contacts is that they don't use batteries. This means that a user will never have to buy new batteries for their hardwired contact. There are all types of door sensors in both the hardwired and wireless variety.

If you choose a hardwired contact, you will need to have a hardwired zone available on your system. Most hardwired contacts can be used with nearly any system that supports hardwired sensors. On the other hand, if you choose a wireless contact, you will need to have a wireless zone available. You will also need to make sure the wireless contact communicates at an RF frequency that is compatible with your system. Knowing which wireless RF signals are accepted by your alarm system is very important for getting sensors to work properly. Some of the most popular RF signals used by alarm systems include 319.5 MHz, 345 MHz, 433 MHz, 915 MHz and 2.4 GHz. Remember to always make sure the wireless door contact you choose operates at a frequency that works with your alarm system!

Another major distinction for door contacts is whether they are surface-mounted or recessed. A surface-mounted contact is visible on the outside of the door. A recessed contact is hidden inside the door and its frame. As a general rule, surface-mounted contacts are easier to install, since no holes need to be drilled. But the advantage to recessed contacts is that the end result can appear neater, since no sensor will be visible. We generally recommend that users installed surface-mounted sensors, due to the fact that they are easier to install and generally offer more reliable performance.

With that in mind, door sensors can be assigned to one of four major categories. These are wireless surface-mounted contacts, wireless recessed contacts, hardwired surface-mounted contacts and hardwired recessed contacts. Regardless of which category a door contact is assigned, these devices generally all work in the same way. Most door contacts consist of a sensor and a magnet. The sensor is installed on the stationary portion of the door frame, while the magnet installed on the moving portion of the door. In most cases, the magnet must be within a half-inch of the sensor. Placing the sensor itself on the stationary portion of the door helps prevent it from being damaged when the door is opened or closed. Once the door is opened, the magnet will separate from the sensor and cause a reed switch inside the sensor to activate. The sensor will then alert the system to let it know that the door has been opened. Please note that there are a few door sensors that are exceptions to this general operation. Namely, recessed sensors that use a plunger switch, like the wireless Honeywell 5800RPS and the hardwired Honeywell 956RPT.

Before we get into general door contacts that would be used for most applications, we want to make special mention of some more unique sensors that would be used for specific setups. Honeywell offers many hardwired wide-gap contacts that can be used with garage doors and industrial applications. The advantage to these sensors is that they can utilize a much larger spacing gap between the sensor and magnet than what is possible with standard door contacts. We have seen some industrial contacts where the spacing gap can be up to 2.5 inches. That's five times the recommended maximum spacing gap for standard door contacts! Some examples of these industrial-grade hardwired contacts include the Honeywell 958, the Honeywell 968XTP, the Honeywell 959, the Honeywell 958-2, the Honeywell 950W, the Honeywell 960 and the Honeywell 7945. Many of these industrial-grade contacts are also suitable for outdoor use. Another option for a garage door is to use a tilt sensor, like the Honeywell 5822T or an Interlogix TX-E401.

But if a user requires a wireless contact for an outdoor application, there only option is really the Honeywell 5816OD. This wireless contact offers a recommended maximum spacing gap of 1.5" inches, and it is great for use with fences and outside doors. It has a nominal range of 200 feet when used with most systems. As a 345 MHz Sensor from the Honeywell 5800 Series, it will work with nearly any Honeywell Alarm System.

If you don't require an industrial or an outdoor contact, you will most likely be able use a relatively standard contact with your alarm system. We prepared a table below that outlines many of the most popular and widely used door contacts sold by Alarm Grid. Please note that not every contact is included - there would be too many to list! But this is a good chart to help you find the perfect sensor for your system.

If you're still having trouble deciding on the perfect door contact for your alarm system, our experts are always happy to help. You may email us at support@alarmgrid.com, and we will get back to you as soon as possible. You may also call us at (888) 818-7728 during normal business hours, which are 9am to 8pm EST M-F.

Honeywell is known for producing some outstanding security equipment, and their wireless door and window contacts are no exception. With wireless contacts available from both the 5800 Series lineup and the SiX Series lineup, there are certainly some great options. But with all the possibilities, it might seem overwhelming if you are just getting started. This guide will help you choose the perfect wireless Honeywell door and window contact for your needs.

First, a user should understand exactly how a door and window contact works. Almost every wireless Honeywell door and window contact functions using the exact same principles. These devices consist of a sensor and magnet. The sensor is the "brains" of the operation, and it is responsible for sending signals to the alarm system. It is typically installed on or inside the door or window frame. The magnet is installed on or inside the door or window itself. The only wireless Honeywell contact that does not use a magnet is the Honeywell 5800RPS. This is a wireless recessed sensor for doors only that operates using a plunger switch.

For proper operation, the device's magnet should be installed very close to the sensor. We usually recommend placing it within a half-inch of the sensor. However, some 5800 Series contacts, like the 5816OD, can function properly with a slightly larger spacing gap. When the door or window is opened, the magnet will separate from the sensor. This will cause a reed switch inside the sensor to activate. When this happens, the sensor will send a signal to the alarm system so that the programmed Response Type can be performed.

It's also important to know the system compatibilities for the different Honeywell wireless contacts. Their wireless contacts come from two different sensor lineups. These are the 5800 Series and the SiX Series. The 5800 Series contacts are unidirectional devices that operate at 345 MHz. This makes them compatible with any Honeywell System or 2GIG System. But the SiX Series contacts are bi-directional, fully encrypted sensors that communicate using 2.4 GHz WIFI. These sensors only work with Honeywell Lyric Systems.

If you have a Honeywell Lyric Controller, then you can choose between any Honeywell wireless contact on the market. But if you have a LYNX Touch or a VISTA System with an added wireless receiver, then you are restricted to the 5800 Series contacts. Additionally, if you are using a 2GIG GC3 or a 2GIG GC2, then you can use either 2GIG Contacts or Honeywell 5800 Series contacts. Any alarm systems that do not accept the 345 MHz frequency are unable to use Honeywell contacts.

The only two contacts in the Honeywell SiX Series Lineup are the Honeywell SiXCT and the Honeywell SiXMINICT. These are both wireless, surface-mount sensors that work exclusively with Honeywell Lyric Systems. What makes these sensors special is that they feature 128-bit AES encryption. Whenever the sensor sends a command to the Lyric System, the system must then send a secure response back to the sensor. The command will only go through if this secure response is received. Many security experts refer to this as a "digital handshake", and it is excellent for preventing any hacking attempts or wireless attacks.

The SiXCT and the SiXMINICT do have a few slight differences. Most notably, the SiXMINICT is smaller and more compact than the SiXCT. The SiXCT measures at 3.13”L x 1.61”W x 1"D, while the SiXMINICT measures at 2.44”L x 1.25”W x .45”D. So users who want a smaller sensors should go with the SiXMINICT. But the benefit of the SiXCT is that it features a larger wireless range (~300 feet) than the SiXMINICT (~200 feet). However, only users with particularly large properties should have to worry about signal range. One thing that these sensors do share in common is that they can both be batch-enrolled with the Lyric Controller.

• Honeywell SiXCT - The standard SiX Series contact. Features a 300 foot range and encryption. Will only work with Lyric Systems.
• Honeywell SiXMINICT - The more compact SiX Series contact. Provides a 200 foot range and encryption. For Lyric Systems only.

But the SiX Series contacts aren't for everyone. For one, they will only work with the Lyric Systems. There are also no recessed contacts in the SiX Series lineup. Users who don't have a Lyric Controller or want a recessed sensor should look to the Honeywell 5800 Series instead. This is an incredibly diverse sensor lineup that has an appropriate contact option for virtually any situation. Any Honeywell or 2GIG System will work with these sensors. This includes any Lyric Controller, L7000, L5210, VISTA P-Series, 2GIG GC3, 2GIG GC2 and more. Most 5800 Series contacts feature a 150-200 foot wireless range that can be effectively doubled with the use of a 5800RP Wireless Repeater.

When selecting a 5800 Series Sensor, a user will choose between a surface-mount contact and a recessed contact. With a surface-mount contact, the sensor and the magnet are mounted on the outer surface of the door or window and its frame. But with a recessed contact, the sensor and magnet are installed inside the door or window and its frame. Surface-mount sensors are very easy to install, since they only require screws or double-sided foam tape. But the sensor will be visible on the outside of the door. Recessed sensors are more difficult to install since holes will need to be drilled. However, some users will appreciate the fact that recessed sensors are hidden.

For users who go with a surface-mount sensor there are certainly some great options in the 5800 Series. One of our favorites is the 5800MINI. This is a reliable sensor that boasts an impressive 200 foot range, despite its small size of just 2.2"H x 1"W x 0.25"D. This is arguably the best surface-mount contact in the Honeywell 5800 Series.

• Honeywell 5800MINI - A small and discreet surface-mount contact. Offers a 200 foot wireless range. Great for almost any application.

But there are other surface-mount options than just the 5800MIIN. The 5816 is the most popular sensor that Honeywell has ever offered. It features a larger size and roughly the same range as the 5800MINI. But unlike the 5800MINI, the 5816 can be used as a wireless transmitter for a normally closed hardwired device. Honeywell also offers the 5820L Slim Line for narrow installations and the 5816OD for outdoor use.

• Honeywell 5816 - Honeywell's most popular sensor. Can also be used as a wireless transmitter for a single NC hardwired device.
• Honeywell 5820L - A slim line door and window contact that is great for narrow applications. Features a 150-foot range.
• Honeywell 5816OD - A surface-mount contact for outdoor installations. Excellent for monitoring fences, sheds and detached garages.

Honeywell also offers some less popular 5800 Series contacts. These include the 5811 (discontinued), the 5814, the 5815 and the 5816MN (discontinued). While these sensors will work just fine, there isn't really any reason to choose them over another 5800 Series contact.

• Honeywell 5811 - A small and discreet sensor that has since been discontinued. Replaced by the Honeywell 5800MINI.
• Honeywell 5814 - Another compact sensor option. It is not as robust as the 5800MINI. Its wireless range is only about 100 feet.
• Honeywell 5815 - An aesthetically pleasing surface-mount contact that has roughly the same functionality as the 5816.
• Honeywell 5816MN - A discreet surface mount sensor that has been discontinued. Replaced by the Honeywell 5816MN.

There are also several great recessed contacts in the 5800 Series. The Honeywell 5818MNL is a relatively standard recessed contact that can be used with almost any door or window. It features a 200-foot range, and the installation only requires minor drilling. The Honeywell 5800Micra is a recessed contact for windows only. It is a very small sensor with an attached antenna for sending wireless signals. Finally there's the 5800RPS, which uses a plunger switch instead of a sensor and magnet. This sensor can only be used with doors. When the door is closed, the plunger switch will be pressed in. Once the door is opened, the plunger switch will come out and activate the sensor.

• Honeywell 5818MNL - A standard recessed contact for doors and windows. It is easy to install, and it has a 200 foot range.
• Honeywell 5800Micra - A small recessed contact for windows only. Its antenna must be adjusted carefully when installing.
• Honeywell 5800RPS - A recessed sensor that uses a plunger switch instead of a magnet. For use with doors only.

Door alarm sensors, or contacts, are some of the most important devices used with security systems. These devices alert a user whenever their door is opened. They can be used on virtually any type of door. These might include a front door, a back door, screen doors, a patio door, a shed, cabinets and any door inside the building. We typically find that door alarm sensors are some of the easiest to use devices with an alarm system. But still, it can be helpful to read through a comprehensive guide explaining the full ins and outs of these devices. So it here is - everything you've ever to know about door alarm sensors.

The Basics of Door Alarm Sensors

Most traditional door sensors feature a relatively simple design and premise. These devices usually consist of a sensor and a magnet. The sensor is placed on or inside the door frame, and the magnet is placed on or inside the door itself, within a half inch of the sensor. Opening the door will cause the magnet to pull away and separate from the sensor. When this happens, a reed switch inside the sensor will activate. This will cause the sensor to send a signal to the security system, letting it know that the door was opened. The system will then perform the appropriate response based on how the sensor's Response Type was programmed. At the surface, it's all very simple. Some examples of these traditional sensors include the Honeywell 5800MINI, the Honeywell SiXMINICT and the VERSA-2GIG Sensor. Traditional door sensors can be either surface-mounted or recessed.

There's also a second variation of door sensors, known as mechanical door sensors. This type of sensor features a physical switch that is pressed down when the door is closed. When the door is opened, the switch will pop up, causing the sensor to activate. From there, the system will perform the Response Type assigned to the zone for that sensor. This type of door alarm sensor is far less common than the other type of sensor. However, the end result is still the same - the system will still perform the programmed Response Type when the sensor is activated. An example of this type of sensor is the Honeywell 5800RPS. While you are less likely to come across this type of door sensor, it's still worth mentioning just in case. Mechanical door sensors are only available in the recessed variety.

Types of Door Sensors - The Two Distinctions

Now that you know the very basics of door sensors, you can start thinking about the different types. While almost every door sensors operates using one of the two mechanisms mentioned above, there are two other distinctions that are commonly made between door sensors. These are whether the door sensor is wireless or wired and whether the door sensor is surface-mounted or recessed. These considerations will play a big role in determining which door sensor you choose to purchase for your alarm system.

A wireless door sensor will communicate with an alarm system wirelessly. This will prevent the need for running a wire from the system to the door sensor. This can make wireless door sensors significantly easier to install. Another great aspect of wireless door sensors is that they can usually be auto-enrolled with the security system. That said, a wireless sensor will need to have its battery replaced every three to five years. On the other hand, a wired door sensor will need to be physically connected with the alarm system. This can make the installation considerably more difficult in certain cases. However, a wired sensor will never require any battery replacements.

If you are using a wireless door sensor with a wired alarm system, such as a Honeywell VISTA Panel, then you will need to use a wireless receiver. This will allow the wireless signal to be received by the system. When choosing a wireless door sensor, make sure that the wireless frequencies it uses are compatible with your alarm system. For example, Honeywell Panels look for wireless signals that operate at a frequency of 345 MHz, while Qolsys Panels use signals that operate at a frequency of 319.5 MHz. If you try to use a wireless door sensor that does not communicate at the correct wireless frequency, then it will not function with the alarm system.

The other major distinction between door sensors is surface-mount sensors versus recessed sensors. Simply put, surface-mount sensors are installed on the outside of the door and its frame, while recessed sensors are installed in the inside. Surface-mount sensors require no drilling. In the easiest scenario, it is possible to mount them using a double-sided adhesive (foam tape). They can also be mounted using screws. With their easier installation, this is generally the preferred type of door sensor. Most users do not mind the fact that a small sensor will be visible on the outside of the door.

However, for users who do want a more discrete installation, there are recessed door sensors. These sensors and their magnets need to be inserted into holes that are drilled into both the door and the frame. The exact size of the holes will depend on the specific model of the recessed door sensor that is being installed. Once the sensor and magnet have been installed, they will not be visible from the outside. That said, most users opt for surface-mount door sensors due to the easier installation.

Some Notes on Response Types

The primary function of any security sensor is determined by its Response Type. This refers to what action the system will take when the zone is faulted (e.g. the door is opened). Below are the Response Types that are most commonly used with door sensors:

• Entry / Exit: If the door is opened while the system is armed stay or armed away, then the system will need to be disarmed within its entry delay period. If the system is not disarmed within this time period, then an alarm event will occur. Most alarms will feature two different Entry / Exit settings. This allows two different entry delay periods to be used on the same system for different zones.
• Perimeter: If the door is opened while the system is armed stay or armed away, then an alarm event will occur immediately.
• Interior Follower: If the system is set to armed away, an alarm event will immediately occur if the door is opened, assuming that an entry / exit zone is not faulted first. If an entry / exit zone is faulted first, then the system must be disarmed within its entry delay period, otherwise an alarm event will occur.
• Interior With Delay: If the system is set to armed away and the door is opened, then the system must be disarmed within its entry delay period. If the system is not disarmed within this time period, then an alarm event will occur.
• Day / Night: If the system is disarmed and the door is opened, a trouble event will occur on the system. If the system is armed away or armed stay and the door is opened, an alarm event will immediately occur on the system.
• 24 Hour Audible: Opening the door will immediately cause a full system siren and an alarm to be set off, regardless of what state the system is currently in. This Response Type should not be used unless the door should never be opened for any reason.
• 24 Hour Auxiliary: Same as 24 Hour Audible, but only the panel itself will produce a siren. Any external sirens or noisemakers will not activate. This zone type is ideal for emergency medical cabinets that would only be opened in a serious medical emergency.
• 24 Hour Silent: Same as 24 Hour Audible, but no siren or sound will be produced.
• Fire No Verification: Opening the door will immediately cause a fire alarm to be set off, regardless of what state the system is currently in. This is the ideal Response Type for fire doors.

Certain Response Types are only available for certain Device Types. Depending upon the panel you are using, not all of these Response Types will be made available for the Device Type of "Door". A way to work around this is to set the Device Type to "Other". This will allow you to set any possible Response Type for the door sensor.

Other Programming Settings

Programming a door sensor has to do with more than just the Response Type and the Device Type. Below are some of the other programming settings available for a door sensor. Please note that these settings are specific for a Honeywell Lyric Controller, and different settings may be available on another type of panel.

• Serial Number: This is how the system will specifically identify the exact door sensor that is being used.
• Loop Number: This tells the door sensor what function it should perform. Each door sensor usually has a specific loop number that should be set for the device to function as a door sensor. Some door sensors have multiple possible functions that can be used with the device. One example is the Honeywell 5816, which can be used as both a door sensor and as a wireless transmitter depending upon the loop number that is set.
• Zone Descriptors: These serve as the name of the door sensor. The panel will announce the zone descriptors whenever the zone for that sensor is affected.
• Alarm Report: This tells the system whether or not it should send an outbound signal to the central monitoring station. If you turn this off, then all the sounds and sirens will still be made, but a distress signal will never be sent to the central station. An example for turning this off might be if you are monitoring a liquor cabinet to make sure your teenage doesn't get into it. You might want a very loud siren to go off so that you know if this happens. However, you obviously wouldn't want the police to show up at your house in this situation!
• Chime: This will have the panel produce a simple chime whenever the door is opened. Many panels will allow you to toggle between different chime options for the panel. Remember, you will still need to have the local chime for the system enabled from the main settings menu.
• Supervision: This will have the system monitor the door sensor for low battery or loss of signal. Keep this enabled to make sure that the door sensor is always in proper working order. This setting is only used with wireless door sensors.

For any programming questions related to a specific panel, please consult the programming guide for that panel. This information is readily available on the Alarm Grid website in the form of FAQs.

Common Door Sensor Questions

Below are some questions that are commonly asked about door sensors:

1. How do I program my door sensor?

If it is a wireless door sensor, it can most likely be auto-enrolled.This is accomplished by accessing zone programming on the system and then faulting and restoring the door sensor three times to learn it in. You can fault and restore the door sensor by separating the sensor and the magnet and then clicking them back together. From there, make any necessary programming configurations on the panel. See the above information on Response Types and other programming settings.

If it is a wired door sensor with a hardwired VISTA Panel, then we recommend consulting this FAQ. You may also need to consult the VISTA 15P and 20P Programming Guide.

2. How long do door sensor batteries last?

A wireless door sensor will typically require a battery replacement every three to five years. Wired door sensors do not use batteries, and they will never require a battery replacement.

3. How close should the door sensor be to its magnet?

We usually recommend placing the door sensor magnet within a half inch of the sensor. Some sensors may allow for a greater separation distance than others before a faulted zone will occur. The closer the magnet is to the sensor, the less likely an unwanted fault or a false alarm is to occur.

4. Are there any encrypted wireless door sensors?

Yes, there are encrypted wireless door sensors. The Honeywell SiXCT, the Honeywell SiXMINICT, the Qolsys IQ DW MINI-S and the Qolsys IQ Recessed Door-S are all encrypted wireless door sensors.
