Apollo Orbis Conventional Heat Detector
Summary
The Orbis Heat Detector is designed to provide reliable heat detection in environments where smoke detectors may not be suitable. This range includes various classes of heat detectors, each tailored for specific operating conditions. The detectors utilise advanced thermistor technology to measure temperature changes, ensuring accurate detection while minimising the risk of false alarms. With classifications based on ambient temperature and response type, the Orbis Heat Detector is ideal for a wide range of applications.
