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 ambient 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.
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.
