The System Sensor 5602 Mechanical Heat Detector provides dependable fire detection for environments where smoke detectors are impractical due to dust, dirt, humidity, or normal airborne contaminants. This model combines a 194°F (90°C) fixed-temperature sensor with a rate-of-rise (ROR) element that activates when temperatures increase rapidly at approximately 15°F (8.3°C) per minute.
The self-restoring rate-of-rise feature allows for convenient field testing without replacing the detector, while the fixed-temperature element provides dependable protection against sustained heat conditions. The low-profile design blends into commercial, industrial, institutional, and utility spaces while maintaining code-compliant performance.
