Working Principle: Heat detectors respond to changes in temperature. There are two main types: fixed-temperature detectors and rate-of-rise detectors. Fixed-temperature detectors trigger an alarm when a specific temperature is reached, while rate-of-rise detectors activate when the temperature rises rapidly.
Suitability: Suitable for environments where smoke detectors may yield false alarms due to dust or other airborne particles.
