Wireless Smoke Detectors Posts

Johnson Controls, the parent company of DSC and Qolsys, recently released a technical advisory regarding the DSC WS4936 Photoelectric Smoke Detector. Pressing the "Test" button on the device will only trigger the sounder and will not cause the detector to transmit a wireless alarm signal.

The DSC WS4936 Photoelectric Smoke Detector operates at 433 MHz. This is not a DSC PowerG bi-directional smoke. When the "Test" button is pressed on an affected unit, it will sound the smoke detector's built-in sounder, but it will not transmit a signal to the alarm panel, and therefore will not cause an alarm on the panel during the test. In order to properly test the smoke detector, canned smoke should be used. This has the added benefit of being a functional test, and not just a test of the sounder and the transmitter for the WS4936.

Not all DSC WS4936 Smoke Detectors are affected by this issue. In fact, it's a relatively small number. Units produced between February 2022 and April 2022 are the only ones affected. You can determine if you have an affected smoke detector by checking the Date Code on your unit. To check the Date Code, find the ESN sticker. The Date Code will be a 4-digit number. The first two digits are the year of manufacture, the last two digits indicate the week of that year. February through April would show Date Codes of 2207 - 2217. New units without this anomaly will begin shipping in early May 2022.

If you determine you have a DSC WS4936 that is affected by this issue, and you would like to replace it, DSC will gladly do so. Contact your distributor or the alarm dealer you purchased the smoke detector from, and they can confirm the issue and arrange a replacement. However, these units still work perfectly well. In order to continue using an affected unit, all you need to do is be sure you test using canned smoke, as opposed to just using the "Test" button on the unit. If you purchased an affected unit from Alarm Grid, contact us by emailing support@alarmgrid.com, referencing your order number and this post. We will be happy to assist you with a replacement.

We're checking out the best environmental sensors for our top security system picks for the 2020 holiday shopping season, which are the Honeywell Lyric, the Qolsys IQ Panel 2 Plus, and the 2GIG GC3e. Environmental sensors include life-safety sensors, flood sensors, and temperature sensors.

If you haven't seen our alarm panel 2020 holiday buying guide or our security sensor 2020 holiday buying guide, then be sure to go and check those out, as they will give a nice introduction to this buying guide for environmental sensors. You will need to make the same compatibility considerations for environmental sensors as you do for security sensors. The sensors you choose must be compatible with your system and communicate at a wireless frequency that is accepted by the alarm panel you are using.

As a refresher, here are the compatible sensor lineups for our recommended systems. Just like last time, the sensor lineups that are italicized and underlined represent the encrypted sensors that provide extra wireless security and protection.

• 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

While security sensors look for signs of forced entry and unauthorized access, environmental sensors look for undesirable environmental conditions. Specifically, we offer environmental sensors that look for life-threatening conditions, such as a fire or the presence of carbon monoxide (CO) gas. We also offer environmental sensors for detecting floods, water leaks, and unusually high or low temperatures that indicate a broken HVAC system. We will cover each type of environmental sensor in greater detail later in this holiday buying guide.

Adding environmental sensors to your system offers a few advantages. For one, it makes your alarm system more versatile so that it is looking for more than just security breaches. You will also be able to check off more boxes on your certificate of alarm (CoA), and that could lead to bigger savings on your home owner's insurance. Make sure to check with your insurance company to see if that is the case.

Life-Safety Sensors

Life-safety sensors monitor for unsafe environmental conditions that could result in a loss of life. Specifically, this group is primarily comprised of smoke and heat detectors and carbon monoxide sensors. There are also special combination sensors and listening modules that we will discuss further down the line.

First, we will take a look at some of our most popular smoke and heat detectors. These sensors monitor for both the smoke and extremely high temperatures associated with a fire. It is recommended that you have at least one (1) of these sensors on each floor of your building, particularly inside of sleeping areas and in central and connecting areas such as living rooms and hallways.

When checking out these sensors, you might also look for one-go-all-go functionality. This means that when one detector on the network activates, all of the other compatible sensors on the network will also activate their sounders. This can be very important for ensuring that everyone is alerted to the emergency. Certain jurisdictions may require one-go-all-go as part of building codes, so check with your local fire marshal to see if that is the case.

Here are our top picks for smoke and heat detectors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Honeywell SiXSMOKE	Honeywell SiX Series	Lyric	300 Nominal Feet	128-bit AES	Encrypted photoelectric smoke detector and 135°F fixed temperature and 15°F per minute rate-of-rise heat detector w/ 85 dB sounder. Supports One-Go-All-Go.

Now let's look at carbon monoxide sensors. These devices respond upon detecting unusually high levels of carbon monoxide (CO) gas. This gas is both odorless and tasteless, making it virtually impossible to detect without a proper sensor. The gas is extremely harmful to humans, and it can result in serious injury or death in a matter of minutes. We recommend installing at least one CO detector on each floor of your home or office. They are often installed outside of garages and furnace rooms where CO events are most likely to occur.

Here are our top picks for carbon monoxide sensors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
DSC PG9933	PowerG	All IQ Panel 2 Plus	2,000 Feet Open Air	128-bit AES	PowerG CO Detector w/ 85 dB sounder.

Qolsys IQ Carbon	Qolsys 319.5 MHz Series	319.5 MHz IQ Panel 2 Plus	300 Nominal Feet	None	Qolsys CO Detector w/ 85 dB sounder.

We also want to give some special recognition to some combination smoke and CO detectors from Honeywell. These sensors combine fire detection with carbon monoxide detection into one convenient life-safety device.

Here are our top picks for combination smoke and CO detectors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Honeywell SiXCOMBO	Honeywell SiX Series	Lyric	300 Nominal Feet	128-bit AES	Encrypted photoelectric smoke detector and 135°F fixed temperature heat detector and CO detector w/ 85 dB sounder. Supports One-Go-All-Go.

Lastly, we want to mention a pair of listening modules. These devices actively listen for the Temporal 3 (T3) sound of an activated smoke detector or the Temporal 4 (T4) sound of an activated carbon monoxide sensor. These are commonly used with wired smoke detectors and CO detectors that would otherwise have no way of interfacing with an alarm system. If your smoke detectors or CO detectors are one-go-all-go, then, a single listening module can take over your entire wired detector network.

Here are our top picks for smoke & CO listening modules.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Encore FireFighter FF345	Encore 345 MHz Series	Lyric, GC3e, 345 MHz IQ2+	200 Nominal Feet	None	Offers both T3 Detection for Fire & T4 Detection for CO
Interlogix SLX-AD-T3	Legacy Interlogix 319.5 MHz	319.5 MHz IQ Panel 2 Plus	200 Nominal Feet	None	Only offers T3 Detection for Fire. Not for use with CO detectors.

Flood Sensors

Next, we'll be looking at flood sensors. These devices use probes to detect water caused by a flood or leak. It only takes a small amount of liquid to activate one of these sensors, so your system will be alerted before any serious damage occurs. Many of these sensors double as temperature sensors, so expect to see quite a bit of cross-over with that section as well. For best results, use your flood sensors in low-plane areas where leaks are likely to occur, such as underneath toilets, water heaters, and in basements. You might also see that some flood sensor have a reporting delay that is used for false alarm prevention. This will be listed in the notes section in the table when applicable.

Let's check out our top picks for flood sensors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
DSC PG9985	PowerG	All IQ Panel 2 Plus	2,000 Feet Open Air	128-bit AES	PowerG Flood Sensor w/ 6-Foot Detection Probe.

Temperature Sensors

The final type of environmental sensors we'll be checking out are temperature sensors. These sensors look for unusually high or low temperatures that indicate a broken HVAC system. When a temperature sensor is used for high-temperature detection, it should not be confused with a heat detector that looks for extreme temperatures only associated with fires. Instead, the high-end for a temperature sensor will usually activate at around 90°F. When a temperature sensor is used for low-temperature detection, it will sometimes be referred to as a freeze sensor. On the low-end, a freeze sensor will typically activate at a slightly higher than the temperature at which water freezes, which is 32°F. This is done to give the end user a bit of notice so that they can take action before the pipes freeze. You can typically expect a freeze sensor to activate between 40°F and 45°F. Most temperature sensors will offer both high and low temperature detection. And just like in the previous category, there is a lot of crossover with flood sensors, so you may see some repeats from the previous selection.

Here are our top picks for temperature sensors.

Hi DIYers! Today, we're taking a look at the 2GIG SMKT8e-345. This is a wireless encrypted smoke and heat detector that also offers freeze detection. This versatile and effective life-safety combo sensor is designed exclusively for use with the 2GIG GC2e and 2GIG GC3e Security Systems.

Encrypted communication is important for wireless sensors like the 2GIG SMKT8e-345. It prevents anyone from hacking or spoofing the sensor. This way, you can always be sure that it will communicate with the system properly. Many of the newer security systems on the market have their own lineup of encrypted sensors. The 2GIG GC2e and GC3e have the 2GIG eSeries Lineup, and the 2GIG SMKT8e-345 represents the latest addition.

The 2GIG SMKT8e-345 has a photoelectric sensor for smoke detection. This involves using a small light source inside the sensor, coupled with a photo sensor. When smoke enters the chamber, the light will refract onto the photo sensor. The sensor will detect this and alert the system to the fire. This detection method is extremely reliable, and it helps ensure that the system properly responds to any fire. Additionally, the optical chamber for the SMKT8e-345 is designed in such a way that the sensor is more sensitive to synthetic smoke rather than natural cooking smoke. This helps to prevent certain false alarms on the system.

The SMKT8e-345 also uses a fixed temperature and rate-of-rise sensor for extreme heat detection. The heat sensor is triggered in a rather unique way that we've never quite seen with another heat detector. Whenever the sensor detects a temperature increase of 15°F or more in a single minute, it sends a rate-of-rise alert to the panel. But the system will only go into alarm and the sensor will only activate its sounder if the rate-of-rise alert is sent when the sensor detects a fixed temperature of 104°F or higher. The sensor will monitor and report any extreme temperature variations.

We do not have the specifications for the built-in freeze detector at this time. We can assume that the sensor most likely activates at temperatures around 40°F to 45°F and below. This will give you time to take action before the pipes freeze due to a broken HVAC system. Note that the internal sounder for the 2GIG SMKT8e-345 is rated at 90dB. This is good for alerting everyone in an average sized home or a small business. If your system is monitored, the activated sensor will trigger an alarm so that an alert is sent to you and/or a central station. The sensor uses three (3) AAA batteries, and it has an average battery life of 10 years with normal use.

If you have any questions about the 2GIG SMKT8e-345 or any of the products sold on our site, please reach out to us by emailing support@alarmgrid.com. Keep in mind that our support hours run from 9am to 8pm ET M-F. We look forward to hearing from you!

Hi DIYers! Today we are reviewing the brand-new 5800COMBO from Honeywell. The 5800COMBO is a versatile life-safety sensor that is great for any alarm system. It offers smoke, heat and carbon monoxide, all in one convenient device. This reduces the number of life-safety sensors a user will need to install. The device was very reliable in tests, and we have already received great reviews from end users. It definitely lives up to the quality one would expect from a Honeywell sensor. We recommend the sensor for anyone who is starting fresh with new life-safety devices.

The 5800COMBO is a great addition to the Honeywell 5800 Series of wireless sensors. These sensors are easy to program, and they work with a large number of alarm systems. Any LYNX Touch, Lyric Controller, 2GIG GC3 and 2GIG GC2 can use this sensor. The sensor can also interface with Honeywell VISTA Systems using a wireless receiver. But Qolsys System owners must look elsewhere for a wireless life-safety device.

The sensor programs with an alarm system in a somewhat unique way. It requires two wireless zones on the system. One zone is for smoke and heat detection, and the other is for CO detection. Both of these zones use their own 7-digit serial number. The final digit of the CO zone is one digit higher than the fire zone. For example, let's say that the fire zone is 2222222. In that case, the CO zone is 2222223.

Each sensor on the device has shown in testing to operate in a consistent manner. The 5800COMBO smoke sensor will trigger after detecting a small amount of smoke. But this will not set off an alarm on its own. Instead a second trigger must go off for an alarm to occur. This can occur in one of three ways. The first way is for the heat sensor to activate. This will happen if the sensor detects a temperature of 135 degrees Fahrenheit or higher. The second way is for the device's built-in infrared (IR) sensor to detect a fire. The IR sensor will look for the flickering glow of flames. It will trigger an alarm upon sensing this type IR energy. Finally, an alarm will always occur if the sensor detects carbon monoxide.

All this makes the 5800COMBO a very balanced device. You won't have to worry about the sensor triggering any false alarms. That said, it will still activate in the event of a real emergency. Our extensive testing process proved this. One minor concern about the device is that it is a very large sensor. The bulky size will put off some users. But the fact that the 5800COMBO serves dual purposes more than makes up for this. The device also features two prominent test buttons for easy testing. We recommend testing this device on a yearly basis.

The 5800COMBO is UL-listed and CP-01 approved. It can request central station dispatch in the event of an emergency. By installing one, a user can receive a discount on their homeowner's insurance. The amount of this discount will vary between different states and insurance companies. A user should speak with their insurance company to find out more about a possible discount. This is another huge benefit of owning a 5800COMBO.

Alarm Grid completely endorses the 5800COMBO as an outstanding life-safety device. It is one of the most versatile sensors we have ever seen. The device is reliable, and you can count on it in any emergency situation. False alarms are very unlikely to occur, and the insurance benefits you can receive are great. If you already have a standalone smoke or CO detector, then the 5800COMBO isn't for you. In that case, it makes more sense to get a sensor that only includes the function you need. But if you are starting from scratch, the 5800COMBO is second to none. The ability to receive both fire and CO protection in one device in phenomenal. And with the device's reliability and proven performance, you cannot go wrong.

The 5800COMBO is available for sale on our website right now. It is the perfect addition to almost any alarm system. Protect your home and your loved ones with this top-quality Honeywell sensor.

Last week at ISC West, Honeywell received a SIA new product award for the newly released 5800COMBO. The Security Industry Association (SIA) rewards products that balance industry innovation with false alarm prevention. The 5800COMBO encapsulates this criteria almost perfectly. This is the first professionally monitored, fully UL listed wireless heat, smoke and CO combination detector in the industry. This feat alone is quite an accomplishment. The technology packed into the device makes this product even more deserving of this award.

Honeywell did not just integrate standard smoke, heat and CO detection into a single detector housing. They did much more. The individual technologies inside the COMBO are fairly standard. Photoelectric smoke detection, fixed temp (135F degrees) heat detection and electrochemical CO sensing. There is a new infrared (IR) technology designed to pick up ambient light levels and flame flickers. Also the CO detector does have a longer than average life expectancy of 10 years. Everything else is fairly common across other non-monitored combination detectors on the market. So what is it that makes the 5800COMBO so special?

There are 3 programmable zones: smoke (loop 1 with serial), low temp (loop 3 with serial) and CO (loop 1 with serial + 1 on last digit). The low temp and CO zones are standard and only rely on a single sensing element to trip that zone on the alarm system. The smoke zone is much more advanced since this is the most common zone type for false alarms on these types of life safety detectors. This is especially the case in residential environments. It is the "multi-criteria algorithm" that sets this product apart. Yes Honeywell did it again and engineered a state of the art sensor.

The smoke zone requires two of the four sensing elements to be tripped in order to trigger a fire alarm at the alarm system and dial out to a central station. The four elements are photoelectric smoke detection, fixed high temp, CO and the new IR technology mentioned earlier. The first element must be photoelectric smoke detection. Then any of the other three elements in combination with smoke detection will trigger an immediate alarm and report if the system is monitored. If there is only airborne particulate detected the COMBO requires at least 5 minutes of alarm level contact before triggering.

This dual technology of sorts makes the 5800COMBO extremely versatile and less prone to false alarms. That means better protection for your property and more importantly life safety for anyone within the protected premise. False alarms are not only an issue for local authorities. End users are seeing increasingly higher fines per false alarm across the country. That means by using devices like the COMBO will potentially save you money in the event that your local authorities deliver fines for false dispatches.

All in all, we are very excited about the added value of the 5800COMBO to the Honeywell 5800 series line up. The barrier to monitoring smoke, heat and CO just lowered with the introduction of this simple to install, multi-faceted product. We believe that every Alarm Grid customer should have every form of life safety equipped in this device. If you do not already we recommend adding it today!

Note: This is a 5800 series wireless sensor that requires a compatible RF receiver. To confirm panel compatibility you can contact us at support@alarmgrid.com. There is a list of panels mentioned in the product description as well.
