Fire alarm sensor

Smoke detector is for detection of fire & smoke, All smoke detectors consist of two basic parts: a sensor to sense the smoke and a very loud electronic horn to wake people up. Smoke detectors can run off of a 9-volt battery or 9-35V DC. Smoke detector with two types; 4 wires smoke detector (mainly used for burglar alarm system) and 2 wires smoke detector (mainly used for fire alarm system). All our fire alarm detectors (photoelectric smoke detectors, heat detectors, gas leak detectors, carbon monoxide detector) comply with US NFPA72 and Chinese GBJ116 standard.

Gas leak detectors can help you detect a LPG/natural gas/CO leak if you can't or don't notice its smell. When the gas reach to the alarm warning degree, the Gas detectors will make buzz sounds & lights to alert people. Heat detectors detect the temperature of air flow, it will be trigger alarm when the temperature rise above the trip point (fixed temperature: 135 F,  57 C). Our Fire Alarm Detector(smoke,heat, gas) can work with Honeywell/ADEMCO hardwired alarm control panels.
