Wireless Heat Detector

  • Product Description

    Honeywell’s wireless fixed heat and rate-of-rise temperature sensor offers expanded fire detection. Fires typically cause a rapid rise in temperature in the surrounding area. The wireless heat sensor's rate-of-rise thermostat senses the rise in temperature and signals an alarm if the increase is 15° or more per minute. A built-in fixed temperature sensor will also signal an alarm if the environmental temperature rises above 135°F. The wireless heat sensor is UL Listed (UL521) and CSFM approved for commercial and residential applications.


    • Contains a built-in transmitter which can send alarm, supervisory and battery condition messages to the system’s receiver/control unit
    • Powered by a three-volt lithium battery. If the battery voltage gets too low, the 5809 sends a low battery signal to the control panel
    • Features a tamper switch, which causes a trouble signal to be sent to the control if the unit is removed from the mounting base
    • UL Listed for Commercial (when using 5881EH Receiver) or Residential applications
