The Honeywell 5809SS is a wireless fixed temperature and rate-of-rise heat detector. Both technologies offer their own benefits which is why Honeywell decided to keep them bundled in a single sensor. The rate-of-rise heat detection requires a 15F degrees increase within 1 minute. The temperature must be under 100F degrees for ROR detection to activate.

Although rate-of-rise offers unique fire detection for open flame fires the fixed temperature sensing is always a good backup for slow, smoldering fires. There is a 135F degrees fixed temperature sensor designed to trigger a fire alarm on your Honeywell alarm system. If the fixed temperature element is triggered this detector will need to be replaced. It is a single use, non-restorable element.

The original 5809 was replaced by the detector to meet new UL 521 commercial/residential standards but is essentially the same heat detector. It is ideal for residential kitchens where burning food may trigger false alarms on a traditional smoke detector. You may also use it in designated smoking areas inside a building. It is also good to use in bathrooms and garages, where excessive moisture or dust may cause problems for a regular smoke detector.

One 3V lithium battery is specified to power this device for 3 to 5 years. Honeywell requires the following brands to meet this life expectancy: Panasonic CR123A, Duracell DL123, DL123A, or HUIDERUI CR123A.

The Honeywell 5809SS is a wireless fixed-temperature and rate-of-rise heat detector that operates at 345 MHz. This makes it compatible with systems like the Honeywell Lyric, the Honeywell LYNX Touch Panels, the Honeywell VISTA Panels (added receiver required), the 2GIG Panels, and the 345 MHz Qolsys IQ Panel 2 Plus. The sensor is great for locations where installing a conventional smoke detector may result in false alarms. This can include a kitchen, garage, or attic with excessive dust. Overall, the Honeywell 5809SS is a simple, yet effective heat sensor. It gets a 5-Star score from Alarm Grid.

There are many positive aspects regarding the Honeywell 5809SS. Perhaps the biggest positive attribute is the fact that this heat sensor supports both fixed-temperature and rate-of-rise detection. This helps to ensure that the sensor will respond quickly to a fire. The sensor can be readily used in locations where smoke might regularly be present, making it a great alternative to a conventional smoke detector. We also like the fact that this sensor has tamper detection to alert the system if someone removes it from the base.

There are some downsides to the Honeywell 5809SS that should also be considered. As is the case for many standalone heat sensors, the 5809SS is considered a "one-and-done" device. Once it is activated, it will no longer work, and it must be replaced. This doesn't exactly lead to good product value. But even if you don't allow the Honeywell 5809SS to activate from high temperatures, you will still need to replace its CR123A battery on a three (3) to five (5) year basis. We are also disappointed by the fact that the Honeywell 58099SS does not have a built-in sounder. You will be relying on the panel or an external siren to alert building occupants during a fire. While none of these downsides are unusual for a wireless heat sensor, they are still important to consider. But none of these aspects are major deal-breakers, and we can still give the Honeywell 5809SS a 5-Star rating.

Good: Fixed Temp & RoR, Use in Locations Not Suitable for Smoke Detectors, Tamper Detection

Bad: One-And-Done, Limited Battery Life, No Sounder

Bottom Line: 5 Stars

No. The hi temp sensor is a mechanical device that melts at 135 F. and makes an electrical connection. I don't know of anything set for a higher temp that would work here.
I have a Lyric system. I'm looking for a wireless heat detector for my attic. In the winter the attic could get into the negative temps and over 135 degrees in the summer. Is the 5809SS available in 194 degree sensor?
Actually, we had the wrong information up about this previously. This product cannot operate as a stand-alone unit as it has no internal sounder.
Honeywell products are not compatible with Nest products unfortunately.
does this work with Nest?
Yes this does work with the Lyric.
Does this work with Lyric?
Does the Honeywell 5809SS work as a stand alone unit without need for a wireless receiver or controller? I'm looking for a heat detector that I can just attach to the ceiling without any additional tech.
On another page, I asked about the loop numbers. I said that my unit autodetected as loop 4 and wondered if that was correct. Sterling's answer was great so I'll copy it below for other's information: "Loop 4 is the pre-programmed loop for the device's tamper detection so if you auto-enrolled the heat detector to your Lyric by removing the head from the base, it would have auto-enrolled as loop 4. When on loop 4, the device would only ever trigger on tamper and never on actual heat detection. Once you re-save it as loop 1, with Device Type as 'Heat Sensor' and Response Type as 'Fire No Verification', the sensor should activate as expected."
