Apollo Orbis Marine BR Heat Detector (ORB-HT-41003-MAR)

The Apollo Orbis Marine BR Heat Detector (ORB-HT-41003-MAR) provides reliable heat detection for marine 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.

Designed for marine fire alarm systems, the ORB-HT-41003-MAR 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 unwanted alarms while maintaining dependable fire detection.

Its modern low-profile design, wide operating temperature range, and high humidity tolerance make it suitable for demanding marine environments.
