5151AUS series thermal detectors

5151AUS Series of conventional heat/thermal detectors has been designed specifically for the Australian and New Zealand markets using thermistor sensing technology to provide reliable detection of heat which would only be caused by a fire emergency.

These detectors feature dual red LEDs and mounting base interchangability with Notifier's photoelectric smoke detectors. Model 5151RAUS is a low temperature heat detector featuring both fixed temperature and rate-of-rise operation for use in areas below 50°C without rapid temperature increases.


  • Provides fixed point and/or rate of rise operation.
  • Available in low temperature (63˚C) or high temperature (90˚C).
  • Compatible with 100 and 400 series products.
  • Dual LED design provides 360° viewing angle.
  • Thermistor sensing technology.
  • Uses universal B401 plug in base.
  • Low profile.
  • Built-in functional test switch activated by external magnet.
  • 12/24VDC operation.
