The Honeywell 5816MN is a miniature version of a Honeywell 5816 Door and Window Contact Sensor. It retains all of the useful features of the regular 5816, but it is in a more compact size that end users are sure to appreciate. But the sensor has been discontinued, so you will be hard-pressed to find it new. However, Alarm Grid still recommends this sensor if you happen to find a used model somewhere. It will serve you well whenever you open or close your door or window. Therefore, we reward the Honeywell 5800MN with a 5 Star rating, which is the best rating we can give a product.

There is so much to like about the Honeywell 5800MN. It is very small and compact, which will prevent house guests from remarking, "Hey, what is that on your door or window?" It has two (2) programmable loops. The first loop, also known as Loop 1, allows you to connect an external hardwired contact sensor and allow it to communicate with your security system wirelessly. Loop 2 is how you will want to program the 5800MN if you are using it as a contact sensor with its included magnet. Also, the 200 foot nominal range of the 5816 has been retained. And you will enjoy fantastic features like low-battery monitoring, tamper alerts, and RF supervision.

But there are some downsides to the 5800MN that you should consider. The sensor is discontinued, so you will be unlikely to find a new one. But should you come across a used model, it will probably work great. We must admit though, that the 5800MN has a rather dated design. And you will need to replace the CR123A battery periodically. Nonetheless, we like this sensor, and it gets 5 Stars.

Good: Small & Compact, Use as Wireless Transmitter for Wired Contact, 200-Foot Nominal Range, Lots of Features

Bad: Discontinued, Dated Design, Battery Must be Replaced

Bottom Line: 5 Stars

The 2GIG RPTR1-345 is a wireless repeater designed for use with 2GIG 345 MHz Sensors and Honeywell 5800 Sensors. Using this repeater can effectively double the signal range for a compatible wireless sensor. However, the repeater has some restrictions in how it can be used. And while it comes with a plug-in transformer, it does not have a cable for connecting the transformer. But it does include a backup battery for providing a backup power source. Overall, we think the 2GIG RPTR1-345 is a great product, and we give it a 5 Star rating.

There are many aspects we appreciate about regarding the 2GIG RPTR1-345. For one, it can double the range of compatible wireless sensors when positioned appropriately. The 2GIG RPTR1-345 works quite reliably and it is easy for DIY users to set up. We also like the fact that it has LED lights to assist with using the device. The repeater is versatile in the fact that it is used with both Honeywell 5800 Sensors and 2GIG 345 MHz Sensors.

But there are also some downsides to the 2GIG RPTR1-345 that should be considered. Although a plug-in transformer is included, no wiring is provided, so you will need to supply your own. Although the 2GIG RPTR1-345 works with most Honeywell 5800 Sensors, it does not work with those that use two-way communication. Therefore, you cannot use the 2GIG RPTR1-345 with devices like the Honeywell 5828 Keypad and the Honeywell 580WAVE Siren. Also, you cannot repeat a signal more than once, so don't expect using multiple 2GIG RPTR1-345 devices to repeat signals over and over. But you can have two 2GIG RPTR1-345 modules in different directions from the main panel to repeat signals incoming from different sides. Lastly, the RPTR1-345 cannot be used with 2GIG encrypted sensors.

Alarm Grid highly recommends the 2GIG RPTR1-345. It gets 5 Stars.

Good: Doubles Range, Easy to Install, LED Lights, Versatile

Bad: No Wiring, Not for 2-Way 5800 Sensors, Cannot Repeat Signals More than Once

Bottom Line: 5 Stars

The DSC WS4959 Key Fob is a 433 MHz key fob for various 433 MHz security systems. Compatible systems include the DSC Impassa, the DSC PowerSeries Systems with an added wireless receiver, and the 433 MHz Qolsys IQ Panel 2 Plus. The key fob allows a user to control their security system or trigger an emergency panic from anywhere within range. The key fob is also fairly unique in that it offers a 5th button for toggling between different modes. This allows for up to 12 inputs from one single key fob. We really like the DSC WS4959, and we give it a 5 Star rating.

There are many positive aspects regarding the DSC WS4959. For one, its 5th center button is pretty nifty, as it allows a user to toggle between three different modes. The actual commands are performed by pressing any of the surrounding four buttons. This means that up to 12 different functions can be performed using this one key fob device. We also like the LED light, which is useful for determining whether or not a command was sent out. You can also use the light to determine if the battery needs to be replaced.

There are some downsides to the DSC WS4959. The key fob uses a battery, and that battery will need to be replaced every few years. Making matters worse is that this is a CR2025, which can be easily confused with a CR2032. Make sure you get the correct type of coin battery. Also, while the 5th button function is neat, it may be difficult for some users to figure out. But these downsides are relatively minor, and they do not stop the DSC WS4959 from earning a 5 Star rating.

Good: 12 Different Functions, LED Light

Bad: CR2025 Battery, 5th Button Function Can Be Confusing

Bottom Line: 5 Stars

The Honeywell 5811PK10 is a ten (10) sensor pack of Honeywell 5811 Door and window Sensors. These sensors are smaller than their 5816 counterparts, while still retaining most of the features. The product has been discontinued by Alarm Grid, as the Honeywell 5811 is no longer readily available. However, the sensors will still work great if you happen to have any around. We are big fans of the Honeywell 5811, and we like the 10-pack if you really need a large number of these sensors. As a result, we give the Honeywell 5811PK10 a 5 Star rating.

There are many things to like about the Honeywell 5811PK10 and its Honeywell 5811 Sensors. The 5811 is a thin sensor, with just a quarter-inch profile. The makes it almost vanish when placed on a white background. The sensor has a roughly 200 foot range, which makes it suitable for most homes. Keep in mind though that large metal objects and other obstacles can reduce range. We also like the fact that the sensor is easy to program and install. This makes it a good option for DIY users. The sensor is compatible with nearly all 345 MHz security systems.

However, there are some downsides regarding the Honeywell 5811PK10. For one, it is discontinued, so you will be unlikely to find a new pack anywhere. The 5811 has been replaced by the Honeywell 5800MINI, which is an even smaller sensor. Like any wireless sensor, the Honeywell 5811 relies on a battery, and the battery must be replaced about every four (4) years. The sensor uses a CR2032 coin battery, and that could mean a trip to the pharmacy to pick one up if you are not prepared.

Overall, we really like the Honeywell 5811PK10, and it gets 5 Stars.

Good: Thin Profile, 200 Foot Range, Easy to Program & Install, Compatible w/ Many Systems

Bad: Discontinued, Smaller Sensors Available, Battery Must be Replaced Every Four Years

Bottom Line: 5 Stars

The Honeywell IS25100TC is a long-range motion detection sensor. It uses passive infrared (PIR) technology to detect movement. It is a hardwired sensor that must be connected with the panel, a wired expansion module, or a wired to wireless converter. What makes this motion sensor unique is that it detects movement across a very long and narrow area. Its coverage area is measured as 100 feet by 20 feet. This makes it ideal for long hallways, corridors, and other long and narrow areas. Overall, we think this is a very good product, and we give a 5 Star rating.

There are many things to like about the Honeywell IS25100TC. For one, it detects movement across a very long and narrow area, making it suitable for areas with similar dimensions. The sensor has an LED light that is useful for walk testing and performing any necessary troubleshooting. The sensor has settings that are easily configured by adjusting its DIP switches. As a Honeywell product, it is of high quality, and it should last for a very, very long time.

But there are some downsides to the Honeywell IS25100TC that should also be considered. As a motion sensor, it must draw some power from the panel, though this amount is very small. But we have seen a sensor push some users over the appropriate load limits for their panels. While the IS25100TC is generally used as a commercial sensor, it cannot be used with a polling loop panel. This means that it can only be used with wire runs that are somewhat limited in length. In most situations, this won't be a big issue, but it may come into play if you are trying to use the sensor with a long wire run from the panel. The sensor also lacks anti-masking, which would have been a nice addition.

The Honeywell IS25100TC is recommended by Alarm Grid for anyone needing a wired long-range motion sensor for a non-polling loop panel. It gets 5 Stars.

Good: Long & Narrow Coverage Area, LED Light, DIP Switch Settings, Great Build Quality

Bad: Draws Some Power From Panel, Not for Polling Loop Panels, Lacks Anti-Masking

Bottom Line: 5 Stars

The Honeywell 5834-4EN is the exact same key fob as the Honeywell 5834-4, only with an added plastic silver plating. The silver plating is purely for aesthetic purposes, and the key fob is absolutely no different from a standard 5834-4. If you buy a Honeywell 5834-4EN, then you are just spending extra money for the plastic silver plating. And it's not like this is a small difference in price. You will typically find the Honeywell 5834-4EN listed at twice the price of the Honeywell 5834-4. We personally don't recommend spending the extra money in this case. However, the Honeywell 5834-4EN is still a perfectly functional key fob that makes a great addition to any compatible system. We give it 5 Stars for its quality and performance, but we don't recommend buying it.

There are many things to like about the Honeywell 5834-4EN. For one, it allows for both standard security and high security modes. Just keep in mind that the key fob can only work in high security mode when used with the Honeywell LYNX Touch Panels. All other compatible panels can only support low security mode. The buttons on the key fob are easily identifiable and easy to press. An LED light confirms that an input has been made. You can also program various dual-button inputs. This allows for up to eight (8) programmable inputs per Honeywell 5834-4EN Key Fob.

As we already mentioned, the biggest drawback of the Honeywell 5834-4EN is that it is just a glorified Honeywell 5834-4 at double the price. The fact that most security systems do not support high security mode is also a negative. Really, if you are considering this key fob, just get the standard Honeywell 5834-4. But if you already have a Honeywell 5834-4EN, then at least you have a quality product. The Honeywell 5834-4EN gets 5 Stars for its overall performance.

Good: Standard & High Security Modes, Easily Identifiable Buttons, Easy to Press Buttons, Dual-Button Inputs

Bad: Just a 5834-4 With an Added Silver Plating, High Security for LYNX Touch Only

Bottom Line: 5 Stars

The Qolsys IQ Battery is the replacement battery for the original Qolsys IQ Panel Security System. Like most backup batteries, the Qolsys IQ Battery is designed to keep the system temporarily running in the event that AC power is lost. This can be due to the transformer becoming unplugged or disconnected or because of a general electrical outage. The Qolsys IQ Battery should not be confused with the backup battery for the Qolsys IQ Panel 2 or IQ Panel 2 Plus, as that is a completely different part number. Overall, we really like the Qolsys IQ Battery, and we give it a 5 Star rating.

There are many positive aspects regarding the Qolsys IQ Battery. For one, it keeps the system running for up to 24 hours at a time. This is pretty long for a panel backup battery. We also appreciate the fact that the battery has an easy connector for connecting with the panel. You will still need to access the inner panel board, but the process is fairly easy. The battery is rechargeable and will slowly store a charge over time. This is what allows the battery to function properly.

There are not many downsides for the Qolsys IQ Battery. Since the original IQ Panel is not frequently used, not many people will really have a need for the IQ Battery. Remember, this battery cannot be used with an IQ Panel 2 or IQ Panel 2 Plus. Also, like any rechargeable battery, the IQ Battery will lose its ability to store a charge over time. Once that happens, the battery will need to be replaced. Also consider that the battery must installed inside the panel. You will most likely need a screwdriver to access the inside of the panel and complete this process.

We think the Qolsys IQ Battery is a great product if you need a new battery for an original Qolsys IQ Panel. We give it 5 Stars.

Good: Up to 24 Hours of Power, Easy Connector, Rechargeable,

Bad: IQ Panel is Uncommon, Not for IQ2 or IQ2+, Will Eventually Require Replacement, Must be Installed

Bottom Line: 5 Stars

The Alarm.com ADC-SEM110-VT-VZ is a cellular communicator for a Honeywell VISTA P-Series System. But unlike most VISTA System Communicators, the ADC-SEM110-VT-VZ allows the system to connect with the Alarm.com servers for monitoring service. This is opposed to the AlarmNet360 servers that are more frequently used with Honeywell Alarm Panels. The ADC-SEM110-VT-VZ connects across the Verizon LTE Network, which is expected to be supported well into the very distant future. Overall, we really like the Alarm.com ADC-SEM110-VT-VZ, and we give it a 5 Star rating.

There are many positive aspects regarding the Alarm.com ADC-SEM110-VT-VZ. For one, it provides ultra-reliable connectivity through the Verizon LTE Network. This network is expected to be maintained well into the very distant future, even as Verizon inevitably releases their 5G network. The Alarm.com service is fantastic, as you can use it to control your system from pretty much anywhere in the world. We also like the fact that the ADC-SEM110-VT-VZ doubles as a Z-Wave Plus controller so that you can start building an automation network around your VISTA Security System. In fact, until the Honeywell PROA7 Panel, this represented the only method for using true Z-Wave Plus with a Honeywell System.

There are some small downsides to the Alarm.com ADC-SEM110-VT-VZ. For one, it is discontinued, and you will likely have trouble finding a new model. A used one should still work just fine, as long as it has been released by the previous monitoring company. There is no IP connectivity for the ADC-SEM110-VT-VZ. Newer Alarm.com Communicators allow for both IP and cellular connectivity, which is also referred to as dual-path connectivity. If you do not have internet service, then this is a moot point, but most users prefer to connect across both IP and cellular. Like any communicator, the ADC-SEM1110-VT-VZ must be installed.

We think the ADC-SEM110-VT-VZ is a great VISTA Communicator, and it gets 5 Stars from us.

Good: Alarm.com, Verizon LTE, Long-Term Solution, Z-Wave Plus

Bad: Discontinued, No IP Service, Must be Installed

Bottom Line: 5 Stars

The Honeywell LTEXV-TC2 is an upgrade kit that features a Honeywell LTE-XV Verizon Cellular Communicator and the PROM Chip upgrades for VISTA-15P and VISTA-20P Security Systems. This is one of the kits you can get if you need both a new communicator and an upgrade for your 15P or 20P. Remember, these systems require the firmware update if they are running less than version 9.12. Overall, this is a very useful kit, and it gets a 5 Star rating from Alarm Grid.

There are many things to like about the Honeywell LTEXV-TC2. For one, it provides reliable connectivity through the Verizon LTE Network. This network is expected to be supported by Verizon well into the very distant future, even as they eventually put their 5G network into action. Therefore, you can expect the Honeywell LTEXV-TC2 to keep your system monitored for many years to come. Both the 15P and 20P PROM Chips are included, making this kit rather versatile. Once the communicator is activated, you will be able to use your system with Total Connect 2.0, provided that the TC2 service is included in your monitoring plan. All of the Alarm Grid cellular plans include access to TC2, with the sole exception of our $25 per month Cell-Only Plan.

There are not many downsides to the Honeywell LTEXV-TC2. The communicator is cell-only, and it cannot connect with AlarmNet360 and TC2 across the internet. This is opposed to the LTEIV-TC2, which is basically the same upgrade kit, except that the LTE-IV supports both IP and cellular. Of course, if you do not have internet service in the area where the panel will be used, then the LTEXV-TC2 is just as good. And really, with how reliable cell service is, you shouldn't notice much of a difference. One other downside might be the fact that the module must be physically installed. It isn't very difficult, even for a DIY user, but it will still take about 5 to 10 minutes of your time. Lastly, this kit is only needed if the VISTA Panel requires a firmware upgrade to support the communicator. Otherwise, just get the standalone LTE-XV Communicator.

The Honeywell LTEXV-TC2 is recommended by Alarm Grid, and it gets 5 Stars.

Good: Reliable LTE Service, Will Last Many Years, PROM Chip Upgrades, Connect w/ TC2

Bad: Cell-Only, Must be Installed, Only for Panels Needing Firmware Upgrade

Bottom Line: 5 Stars

The Honeywell FP280 is a flood detection probe that connects to a flood sensor, such as the Honeywell 5821 or the Honeywell 470-12. It is not an actual sensor, and it cannot really do anything on its own. But when used as a probe with a corresponding flood detector, it works very well. Attached to the Honeywell FP280 is a 16.5 foot cable, and it is possible to replace it with a longer cable if you require something even longer. Overall, we really like the Honeywell FP280, and we give it a 5 Star rating.

There are many things we appreciate a Honeywell FP280. For one, it is easy to connect to a compatible flood sensor, making it good for DIY users. The accessory is quite versatile, as it can be used with nearly any flood detector that has a compatible input available. The 16.5 is pretty long for this type of device, and the option of swapping out a cable is nice too. This can be very useful if the original cable ever becomes damaged, or if you just need something longer. As with most Honeywell products, the Honeywell FP280 has a great build quality. A resistor is attached so that your system can be alerted if someone tries to tamper with this sensor.

There are not many downsides to the Honeywell FP280. The biggest drawback is that this sensor really cannot do anything on its own. It is only useful if it is used with a compatible flood sensor. Also, many sensors do not need a probe like the Honeywell FP280, as they already have a probe included. And some users prefer a built-in probe, as opposed to an external probe like the Honeywell FP280. But these downsides are very minor, and we still give 5 Stars to the Honeywell FP280.

Good: Easy to Connect, Versatile, Long Cord, Can Swap Cord Out, Good Build Quality, Resistor

Bad: Useless On Its Own, Not Every Flood Detector Needs One

Bottom Line: 5 Stars
