Wired Photoelectric Smoke & Heat Detector Model: SM-04

The Wired Smoke Detector is an INPUT DEVICE used for fire detection which is triggered by smoke and heat. The SM-04 is photoelectric type. It can be used independently or as a front-end detector of an alarm system. Upon detection of smoke and heat, the SM-04 automatically generates an alarm signal to control panel and Led indication alarm. The unit has RF and EMI Immunity to interferences produced by radio devices.
