Apollo ORB-HT-11001-APO | Orbis A1R Conventional Heat Detector

The Apollo ORB-HT-11001-APO Orbis A1R Conventional Heat Detector is engineered for reliable fire detection in challenging environments where smoke detectors may not be suitable.

Using a single thermistor, this detector constantly monitors the ambient temperature and triggers an alarm if it detects a rapid rise in temperature or if the fixed threshold of 57°C is reached.

Ideal for dusty or smoky settings such as commercial kitchens, workshops, or industrial areas, the Orbis A1R offers dependable protection against fire hazards that could otherwise go undetected.

The device features a bright red flashing LED at startup, confirming correct operation, and a yellow SensAlert LED that signals any fault conditions.

With the innovative FasTest feature, testing and maintenance are simplified, allowing the detector to be fully tested in just four seconds.
