Honeywell's 5809 Series wireless fixed heat and rate-of-rise
temperature sensors offer expanded fire detection and
installation flexibility. They are 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.
Both the 5809FXT and 5809SS contain 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 5809 Series is UL Listed (UL 521)
and CSFM approved for commercial and residential applications.
