Honeywell 5821 Posts

Some Resideo 5821 wireless flood and temperature sensors manufactured between July and October of 2023 may not transmit properly. They may fail to learn into the alarm panel or fail to transmit when an alarm occurs. Affected units can be returned to the vendor for refund or replacement.

The 5821 is a versatile wireless sensor from the Resideo (formerly Honeywell) 5800 Series sensor line. Alone, it can monitor for high and low temperature conditions. It can also be used with either a remote temperature probe, or a remote flood-sensing probe. The use of either remote probe allows the 5821 to monitor harsh conditions that the circuitry of the transmitter itself cannot endure.

The date code for the 5821 is located on the box it comes in, and should also be visible as a sticker or a printed series of numbers on the circuit board itself. The date code consists of a 2-digit number for the year and a 2-digit number for the week of that year.

In 2023, between week 30 and week 40*, a manufacturing issue caused 5821 transmitters to be produced with a defect that caused affected units not to transmit properly. These units may never learn into the panel, or they may fail to transmit when a monitored condition occurs. This could result in damage to a home or business.

The date codes included in this notice are 2330 (2023, week 30) through 2340 (2023 week 40). Any unit with date code 2342 or later is not affected by this issue. July 24, 2023 begins week 30, and October 8, 2023 ends week 40.

If you recently purchased a 5821 from Alarm Grid, check the date code on the unit. If it falls within the affected range, contact us at support@alarmgrid.com and we will happily provide you with a warranty replacement. You can read the full notification from Resideo here. If you received a unit that would not learn into the panel initially, it is likely that we have already performed troubleshooting with you and have at least begun the warranty replacement process.

For customers who may not read our blog, Alarm Grid is reaching out to anyone who purchased this product from us from March 2023 until now. We will provide information on the notification, how to check the date code, and will gladly replace any units affected.

*Important Note: When this issue was discovered, production of the 5821 was halted and the issue was investigated to discover the root cause. There was no production of the 5821 during 2023 week 41, which accounts for the seemingly "lost week" missing in the above referenced announcement.

Resideo announced last week that due to a required component becoming obsolete, they are forced to discontinue the popular 5800FLOOD sensor. There is still some available stock, so Alarm Grid has not yet discontinued it, but once all stock has been exhausted, the 5800FLOOD is gone for good.

The 5800FLOOD is popular because unlike the 5821, it doesn't require that a water probe be added to the sensor. Water detection is built-in, and configuration is easy. Another benefit of the 5800FLOOD is that it will alert for flooding more quickly than the 5821. The prongs of the 5800FLOOD need only be in contact with water for about 25 seconds before a signal is sent to the alarm panel. The 5821 flood probe must be in contact with water for about three (3) minutes before sending a signal.

In addition to flood sensing, the 5800FLOOD also monitors for extreme cold and/or hot temperatures locally. This is done using a temperature sensor that is built into the 5800FLOOD. For cold temperature sensing, if the ambient temperature drops below 45℉ (7.2℃) for more than 15 minutes, an alert is sent using Loop 1. For high-temperature sensing, if the temperature rises above 95℉ (35℃) for more than 15 minutes, then an alert is sent using Loop 2. The flood sensor transmits using Loop 3.

Now that the 5800FLOOD is being discontinued, the Resideo and Honeywell Home 5821 is the recommended replacement. One drawback to the 5821 is that it requires a remote probe be added for flood sensing, and for freeze sensing. However, only one (1) remote probe can be used per transmitter, so if you need to monitor for both flood and freeze, two (2) 5821s are required.

The 5821 supports the following functions:

For flood sensing, we recommend using the FP280 as it includes wiring, and the required resistor is already in place. With the 470PB, the user is responsible for providing their own wire and must add the 2.2 MΩ resistor themselves. In all cases, wiring between the 5821 and whichever remote probe is used should be made as short as possible, and should not exceed 96" (243cm). Be sure to read the full Install Guide for the 5821 for all of its various quirks.

Supply chain shortages claim another victim in the 5800FLOOD. It seems like only yesterday that we were excitedly telling you about it. What are your thoughts on the demise of this "New and Improved" environmental sensor? Leave us a note in the comments, as we always love hearing from our readers.

Freezing and water damage accounted for 29.4% of Homeowner's Insurance losses by cause in 2019*. From 2015 - 2019, the weighted average cost per accident year was $11,000* for freezing and water damage. Only fire and lightning damage was more costly. But flood damage can often be avoided.

At this time of year, with the worst of winter still ahead of us, our thoughts always turn to incidents of flooding which are caused predominantly by freezing temperatures. In many instances, homeowner's insurance companies want proof that there is both freeze and flood protection in a dwelling as a condition of insurance, or in order to provide the best available rate. With just a few added sensors and tweaks, your existing alarm system can help you prevent freezing and flood damage. Below we'll outline some products and strategies that can help.

To properly protect against this type of damage, it is helpful to know when the temperature in a building drops low enough to cause concern. There are many sensors that can assist in this, and in many cases, a sensor may perform double duty. There are motion detectors that also have built-in freeze sensing, as well as smoke, heat, and combination sensors. Here's a list of just a few, and the systems they are compatible with:

With any of the low-temperature sensing devices above, you can be alerted to dangerously low temperatures within a building. Alerts can come in the form of an email, text, or push notification from either Alarm.com or Total Connect 2.0, a call from the monitoring station, or both. With a Z-Wave or WIFI thermostat you can adjust the temperature when the HVAC system is working, or contact an HVAC service technician when it isn't.

Some of the devices listed in the table above combine freeze and flood sensing into a single unit. Of course, avoiding the presence of water in a location where it shouldn't be is optimal, but in some cases, it may not be possible. Flooding isn't always the result of freezing water pipes. With a flood sensor, you can be alerted to these situations and then take action accordingly. Alarm Grid offers a variety of both wired and wireless flood sensors. Some are listed above. Those and others can be found here.

If you can't control what's happening with the temperature in a location, then the next step in avoiding flood damage is controlling the flow of water. If you have a water shut-off valve within the building, then a Z-Wave water valve is just the thing you need to save the day (and a good deal of money). Once you receive a notification that a freeze condition is possible, or that a flood situation is underway, with Alarm.com or Total Connect 2.0 service, you can either set up a scene to automatically shut off the water within the premises, or you can manually log in and do so remotely.

With a combination of freeze and flood sensors, and a Z-Wave Water Valve, you can anticipate potential low-temperature flooding issues, be alerted to non-freeze-related flooding issues, and either automatically or manually turn off the water before damage occurs. Check with your homeowner's insurance agent to see if there are any discounts available on your policy if you add freeze and/or flood protection with an automated water shut-off option. You may be surprised at how quickly this equipment can pay for itself, even if you never have to use it.

**Qolsys Panels come in a variety of versions. All IQ Panel 2 Plus and IQ Panel 4 versions support PowerG wireless sensors. Then in addition, there are versions that support 319.5 MHz wireless, including S-Line Sensors. There are also versions that support 345 MHz wireless and 433 MHz wireless. When purchasing a Qolsys panel, or a sensor that will be used with a Qolsys panel, be sure to match the receiver type with the sensor type. Panels that support 319.5 MHz come in a box with a Gold stripe. Panels that support 345 MHz sensors come in a box with a Silver or Gray stripe, and those that support 433 MHz sensors have a Red stripe on the box.

As you may know, the fall season began earlier this week. This means that cooler temperatures are on the way. If you want to prepare your home or business, then you will certainly want to consider getting some low-temperature freeze sensors. Nearly every system has good options available!

Freeze sensors alert your system when the temperature in the building drops to a dangerously low level, usually due to the HVAC system being broken. Having one of these sensors in your home or business is crucial for monitoring the building while you are away. The consequences of having below-freezing temperatures in your home or business can be dire. The pipes can freeze, and major damage can occur. Installing a freeze sensor is small price to pay to prevent this from happening.

Most freeze sensors are designed to alert a system before freezing temperatures occur. Usually, a freeze sensor will activate at or around 40°F to alert the system. This a little bit higher than 32°F, which is when water begins to freeze. This function is intentional, as the user will hopefully be alerted to the situation with enough time to take action. Many users will set up notifications on an interactive service platform used with their alarm systems so that they are notified via text and/or email when a freeze sensor activates while they are off-site. This is possible in both Total Connect 2.0 and Alarm.com.

The main thing to consider when choosing a freeze sensor is whether or not it will work with your security system. If you know which sensor lineups are compatible with your system, then you likely already have a good idea which sensors will work. But we'll list out some of the more popular options to get you started. A very versatile 345 MHz freeze sensor that will work with the Honeywell Lyric, the Honeywell LYNX Touch Panels, and any 2GIG Panel is the Honeywell 5821. This sensor can also be used for flood detection if a probe is added.

If you have a PowerG-compatible system, such as any version of the Qolsys IQ Panel 2 Plus, then you might consider the DSC PG9905 Temperature Sensor. Many users prefer PowerG Sensors like the the PG9905 due to their superior wireless range and 128-bit AES encryption. If you have an original, non-Plus IQ Panel 2, then the 319.5 MHz Qolsys IQ Temp-S is a good choice. The Qolsys IQ Temp-S will utilize rolling code encryption when paired with the IQ Panel 2. Users of the 2GIG GC3e and 2GIG GC2e also have a good encrypted freeze sensor option in the 2GIG FT6e-345. There's also the non-encrypted 2GIG FT6-345 for users of the older 2GIG GC3 and 2GIG GC2 Systems.

Alarm Grid wants to help you keep your home or business comfortable this winter, as well as for many more winters to come. If you need help choosing a freeze sensor, then please don't hesitate to reach out to us. We are also happy to discuss monitoring services that you might use to receive alerts regarding a freeze sensor that activates while you are away from your home or office, The best way to reach us is to email support@alarmgrid.com.

A great way to build out your Honeywell Lyric is with Honeywell 5800 Sensors. These are simple, 345 MHz wireless sensors that you can easily enroll with the system for security, life-safety, and environmental monitoring. They are perfect for expanding your system and making it more robust.

When you want to pair a Honeywell 5800 Sensor with the Lyric, the process is very straightforward. Put the Lyric in its auto-enrollment mode by choosing Security > Tools > enter Installer Code (default 4112) > Program > Zones > Add New > Serial Number. Make sure the RF Type on the right-hand side is set to 5800. Then activate the sensor either by faulting it or triggering its cover tamper switch. The Lyric should beep to confirm that it received a signal transmission. Then activate the sensor a second time to have the Lyric display the Serial Number. The third activation will confirm the Serial Number and return you to the screen where you can configure the zone settings.

Programming the zone settings for the sensor is actually quite simple. Depending on how you enrolled the sensor, you may need to adjust the Loop Number. This is almost always the case if you enrolled the sensor by activating its tamper switch. Refer to the instruction manual for the 5800 Sensor to determine which Loop Number to use.

The two (2) Zone Descriptors and the Device Type serve as the name for the sensor. You should choose a name that will help you identify the sensor, e.g. "Front Bedroom Motion Sensor", "South Hallway Door", etc. The Response Type determines how the system responds when the sensor is faulted. See our list of Lyric Response Types for more info.

Alarm Report should be set to Yes if you want the system to report out through AlarmNet to a Central Station if the zone causes an alarm on the system. That is an essential component of alarm monitoring services. Chime is optional, and it has the panel emit any one of several available sounds when the zone is faulted. Supervision tells the panel to look for an RF check-in signal from the sensor periodically to ensure that it is online. Click Save in the bottom-right after you finish adjusting the settings.

Keep in mind that only uni-directional (one-way) sensors from the Honeywell 5800 Series can be used with the Lyric. This leaves out bi-directional devices like the Honeywell 5800WAVE Siren, the Honeywell 5828 Keypad, and the Honeywell 5800RL Relay Module, so make sure you do not buy those for the Lyric. But you still have a lot of excellent sensors and security devices to choose from.

Hi DIYers! As you know, you can't have a security system without some sensors! Of course, with all the possible sensor types it can be overwhelming to decide which ones you really need for your system. While nearly every sensor type serves a purpose, these are the 5 we deem most crucial.

5. Glass Break Sensors

Glass break sensors are used to detect broken windows and other glass break events. These devices have built-in microphones, and they actively listen for the sound of breaking glass. Most glass break sensors utilize a dual-sound detection method. This means that the sensor must detect both the low-pitched thud of an object striking against the glass and the high-pitched shattering of the glass itself. This helps prevent false alarms. Glass break sensors are perfect for monitoring for forced entry into your home. You can even use a single glass break sensor to monitor multiple windows in the same room!

4. Environmental Sensors

Environmental sensors include devices like temperature sensors and flood sensors. These sensors monitor for unusual environmental conditions that likely indicate a problem. For example, a flood sensor will let your system know if there is a water leak that could lead to expensive water damage. Meanwhile, a temperature sensor will monitor for unusually high or low temperatures that indicate a broken HVAC system. There are also many environmental sensors that can perform dual functions and operate as both temperature and flood sensors.

3. Life-Safety Sensors

Life-safety sensors are used to monitor for life-threatening environmental conditions, such as a fire or an outbreak of carbon monoxide gas. These include devices like smoke and heat detectors and carbon monoxide sensors. There are also special combination CO and smoke detectors that can monitor for multiple types of life-safety conditions. Enrolling properly functioning life-safety sensors with your system can mean the difference between life and death. And for fires, you will be able to ensure a faster response if one occurs while you are away. These are a must-have for any system.

2. Motion Detection Sensors

Motion sensors are some of the most useful sensors you can add to your system. These devices alert the system upon detecting a change in infrared (IR) energy caused by movement. There are also some motion sensors that use microwave radar technology in addition to passive infrared (PIR). You can install motions inside your home as interior sensors to determine if anyone gains entry while you are away. They are perfect for detecting general activity and movement in areas where none should be present. There are even pet-immune motion sensors so that you won't need to worry about your pets setting them off. Just make sure you choose the installation area carefully.

1. Door & Window Contacts

Door and window contacts are the easiest to use and most effective sensors for any alarm system. They are used for letting your system know if someone opens up a door or window. These sensors usually consist of two parts, which are a sensor and a magnet. The sensor goes on the door or window frame, and the magnet goes on the moving part of the door or window. Opening the door or window will cause the magnet to become separated from the sensor. The sensor will detect this and alert the system. There are also recessed door and window sensors that allow for a more aesthetically- pleasing installation!

Hi DIYers! It's hard to believe, but it's already May. Time sure flies doesn't it? Summer is quickly approaching and now is a great time to buy temperature sensors for your home. This way, you can be quickly notified if your home's AC system is ever not cooling the building properly.

Temperature sensors aren't just for letting you know about low-temperatures. They can also let you know about unusually high temperatures that would only occur if the AC went out. This is great for ensuring that the house you come home to is nice and comfortably. There's nothing worse than ending your day only to find that your AC went out and your home is uncomfortably hot! Our temperature sensors are also great for pairing with smart thermostats, which can often send you remote alerts when temperatures go outside certain thresholds.

Today, we're taking a look at three temperature sensors that you might consider adding to your system. We'll be focusing on the high-temperature sensing capabilities here, but we may brush over other features as well. Let's take a look!

Honeywell 5821

The Honeywell 5821 has two possible temperature settings. If programmed as Loop 2 with both DIP switches OFF, the sensor will alert the system when the temperature rises above 95°F for more than 10 minutes. You can also set it to SW1 DIP Switch ON and SW2 DIP Switch OFF on Loop 2 to have the sensor activate when the temperature rises above 75°F for more than 10 minutes.

The option to choose between a 95°F and a 75°F threshold is very useful, as some homes in different areas will certainly have different normal temperatures! The sensor also offers freeze detection and flood monitoring when paired with a water detection probe. An optional wired temperature probe is also available. The device operates at 345 MHz.

Qolsys IQ Temp

The Qolsys IQ Temp offers high-temperature detection at 100°F. The zone will then restore when the temperature falls below 95°F. Although this might be too high for many homes, there are some very hot areas that frequently exceed 110°F or even 120°F. This is a relatively simple device that can easily pair with nearly any 319.5 MHz alarm system. It also offers freeze detection at 40°F and restores once the temperature rises above 45°F. Like most temperature sensors, the high and low temperature zones will need to be configured separately.

2GIG FT6-345

The 2GIG FT6-345 Wireless Flood and Temperature Detector is a 345 MHz sensor designed with 2GIG Security Systems in mind. The sensor uses Loop 2 for high-temperature detection. It activates when a temperature of 95°F or higher is detected for three straight minutes. The sensor will restore when the temperature falls below 95°F for three straight minutes. The sensor can also be programmed with Loop 1 for freeze detection (41°F or lower for three straight minutes) or Loop 3 for water detection.

Just last week, Resideo purchased startup company Buoy Labs. This is the first acquisition from Resideo since the company completed its spin-off from Honeywell in October of last year. The purchase of Buoy Labs should greatly assist Resideo in its technology for environmental sensors.

Buoy Labs is best known for its smart home products that allow users to track the amount of water they use and quickly identify leaks. Their lineup fits in perfectly with Resideo. The company already offers many great flood detecting sensors. These include the Honeywell 5800FLOOD and the Honeywell 5821 when used with a Honeywell 470PB Probe or Honeywell FP280 Probe. Many of our monitored customers use these sensors to receive alerts in the event of a water leak. They can then take action before serious water damage occurs. This equipment works great with the wireless panels from Resideo, including the Honeywell Lyric Controller.

We believe that this acquisition will help Resideo make fantastic strides in its offering of environmental sensors, particularly for flood sensors. Buoy Labs has an impressive portfolio of smart home water management and water leak detection products. Resideo has cited industry studies claiming that homeowner's insurance companies pay more than $9 billion in water damage claims every year. The average claim is roughly $9,000. With the purchase of Buoy Labs, we expect that Resideo will achieve great success in reducing these figures and preventing house floods. And if you still don't think flood sensors are important, think again.

Alarm Grid will certainly keep you up-to-date with the latest news regarding any new environmental or flood sensors released from Resideo. This acquisition means Resideo has some big plans in store, and we are very excited to see what the future holds. Stick with Alarm Grid as we move forward in the exciting worlds of security, property protection and home automation!

Hi DIYers! We know it has been awfully chilly out there lately. We thought it would be a good time to talk about freeze sensors and the benefits they provide. These devices are strongly recommended for anyone who lives in a colder area who wants to make sure their home is kept temperate.

Also called temperature sensors, freeze sensors alert a security system when the ambient temperature falls below a certain threshold. Usually, this is around 40 degrees Fahrenheit. That way, the user can take proper action to prevent their pipes from freezing. Remember, water freezes at 32 degrees Fahrenheit, and serious damage can occur if nothing is done in time. There are all sorts of horror stories of this happening while people are away for the day or on vacation.

Freeze sensors are particularly useful when used with an interactive service platform, such as Total Connect 2.0. These services will provide you with mobile alerts so that you will know if a situation occurs while you are away. Nearly every panel we sell can connect with one of these services. You just need the right communicator and monitoring plan.

While there are some standalone temperature sensors, freeze detection is often a secondary feature on a device. In fact, you might already have a device with freeze detection capabilities in your home and not even know it! The feature is commonly found on smoke detectors and flood sensors, so it never hurts to find out if your existing devices can also do freeze detection. For multi-function devices, freeze detection will usually operate on a specific Loop Number, and a unique system zone for freeze detection must be programmed.

If you're in the market for a new freeze sensor, you have plenty of options to choose from. The main thing to keep in mind is whether or not the device will work with your security system. If you are looking for a wireless sensor, then it must communicate at a compatible frequency. If you go the hardwired route, then your system must be able to support hardwired sensors. You might consider getting a smoke detector or a flood sensor that also includes the freeze detection function.

If you have a Honeywell or 2GIG System, then you likely use 345 MHz Sensors. The Honeywell 5821 is a convenient option for reliable freeze detection. You can also add a probe to have the 5821 Sensor double as a flood sensor. If you want a combination smoke and heat detector with freeze detection built-in, you might consider a Honeywell 5808W3.

For Interlogix Systems and the original Qolsys IQ Panel 2, you will want a 319.5 MHz Sensor. The Qolsys IQ Temp is a viable option. There's also the Interlogix TX-E611, which doubles as a flood sensor. For users also looking for a smoke, the Interlogix SDX-135Z also provides freeze detection.

If you have a Qolsys IQ Panel 2 Plus or a DSC PowerSeries Neo, then your system supports PowerG Sensors. In that case, you might go with the DSC PG9905. This sensor will offer the impressive range of PowerG, as well as extremely secure 128-bit AES encryption.

For users who want to go the hardwired route, the best bet is often to go with a smoke detector that includes the feature. We often steer customers towards 2-wire smokes, since they are easier to set up. A good option is the System Sensor 2WTA-B, which also includes a built-in sounder.
