Mechanical heat detector shall be a System Sensor 5600 series model number BK-5624, listed to Underwriters Laboratories UL 521 for Heat Detectors for Fire Protective Signaling

Brand: System Sensor
Part Number: BK-5624

Availability: This item requires 2 business days to process.




The fixed temperature element reacts to heat by responding to a specific temperature setting (194ºF). The detection method is based on the spring action of a metal contact, held to the metal chamber by a fusible alloy. When the temperature reaches the alloy’s melting point, the metal contact will depress the diaphragm, causing the electrical contact to close the circuit. The circular external heat collector is released from the detector to visually indicate that the detector has been activated.
