    Orbis A1R Heat Detector

    The Orbis IS Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. There are seven classes of heat detectors in the Orbis IS range designed to suit a wide variety of operating conditions.

    Please note, all Orbis Detectors require an Orbis Base in order to be mounted.


      • TimeSaver Base designed for fast installation
      • StartUp for fast commissioning
      • FasTest reduces maintenance time
      • Automatic drift compensation, with DirtAlert warning to easily identify dirty detectors
      • Can be used for applications where smoke detectors are unsuitable
      • Ideal in environments that are dirty or smoky under normal conditions
      • Red flashing LED at StartUp confirms the device is operating
      • SensAlert®, yellow flashing LED indicates faulty operation
      • FasTest® takes just four seconds to test and confirm detectors are functioning correctly
