The Honeywell Home 5809SS Wireless Fixed Heat And Rate-of-Rise Temperature Sensor offers expanded fire detection and installation flexibility. It is ideal for hard-to-wire locations and applications that require more than smoke detection. This is a fast and easy install with no wires to run.

The 5809SS contains a built-in fixed temperature sensor, which will signal an alarm if the environmental temperature rises above 135°F. The 5809SS also incorporates an additional rate-of-rise temperature sensor. Fires typically cause a rapid rise in temperature in the surrounding area. The 5809SS rate-of-rise thermostat senses the rise in temperature and signals an alarm if the increase is 15°F or more per minute. The 5809SS is UL Listed (UL 521) and CSFM approved for commercial and residential applications.
