The Orbis heat detector monitors temperature using a single thermistor that provides an output voltage proportional to the temperature of the surrounding air.

• It can be used for applications where smoke detectors are not suitable.
• Ideal for dirty or smoky environments under normal conditions.
• The flashing red LED at startup confirms that the device is functioning.
• SensAlert®, the flashing yellow LED indicates faulty operation.
• FastTest® only takes four seconds to test and confirm that the detectors are functioning correctly.
• Maximum static response temperature 75°C.
