System Sensor 5604

The System Sensor 5604 is a mechanical heat detector for fire alarm systems. It provides fixed-temperature detection at 194°F for property protection applications where smoke detectors are not appropriate. The detector continuously monitors air temperature and triggers an alarm when the temperature rises above the set point, providing low-cost, reliable heat-based fire detection.
