Apollo Orbis A1R Heat Detector (ORB-HT-11001-APO)

The Apollo Orbis A1R Heat Detector (ORB-HT-11001-APO) provides reliable heat detection in environments where smoke detectors may not be suitable. Using a single thermistor, it monitors the surrounding air temperature and responds to both fixed temperature levels and rapid increases in temperature, helping provide early warning of developing fires.

The ORB-HT-11001-APO incorporates several features that simplify installation, commissioning, and maintenance. A red flashing LED confirms correct operation during StartUp, while SensAlert uses a yellow flashing LED to indicate potential faults. The detector also supports FasTest, allowing engineers to test and verify functionality in as little as four seconds.

Designed as part of the Apollo Orbis range, the unit combines dependable performance with advanced maintenance features that help reduce service time and improve long-term reliability.
