Apollo Orbis I.S. CS Heat Detector with Flashing LED (ORB-HT-51156-APO)

The Apollo Orbis I.S. CS Heat Detector with Flashing LED (ORB-HT-51156-APO) provides reliable heat detection for hazardous environments where smoke detectors may not be suitable. The detector monitors temperature using a single thermistor network, which generates a voltage output to match to the surrounding air temperature, making sure of accurate fixed temperature heat detection.

Designed for use in intrinsically safe fire alarm systems, the ORB-HT-51156-APO performs well in environments where dust, smoke, steam, or particles in the air are a part of normal daily operations. By detecting heat rather than smoke particles, the detector helps reduce false alarms while maintaining reliable fire detection.

The integrated flashing LED provides a clear visual indication of detector status, while advanced Orbis technology helps improve detection reliability and minimize false alarms in challenging industrial and dangerous locations.
