Apollo Orbis I.S. CR Heat Detector with Flashing LED (ORB-HT-51154-APO)
The Apollo Orbis I.S. CR Heat Detector with Flashing LED (ORB-HT-51154-APO) monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature.

Please note: this product is now obsolete, the recommended replacement is the Apollo Orbis CR I.S. Heat Detector – ORB-HT-51153-APO.
The Apollo Orbis I.S. CR Heat Detector with Flashing LED (ORB-HT-51154-APO) provides reliable heat detection for hazardous environments where smoke detectors may not be suitable. Using a single thermistor network, it monitors the surrounding air temperature and delivers accurate fixed-temperature heat detection.
Designed for use in intrinsically safe fire alarm systems, the ORB-HT-51154-APO performs well in environments where dust, smoke, steam, or airborne contaminants are present during normal operation. By responding to heat rather than smoke particles, it helps reduce false alarms while keeping reliable fire detection.
The integrated flashing LED provides clear visual indication of the device status, while advanced Orbis technology improves reliability and helps reduce false alarms in dangerous industrial and challenging applications.
