The smoke detector is suitable for industrial and civil building where there is explosive and combustible gas.

 *Voltage:16V~32V DC

*Alarm current:10-100mA

*Static current/voltage:35uA/24VDC

*Working humidity:＜95% RH

*Operating temperature:0℃ to +90℃

*4 wire

*Photoelectric sensor

*Explosionproof function,elegant shell,ceiling mounting easily in minutes

*After installing and switching on power,the detector is in operation state.When it detects the ambient smoke concentration is higher than preset alarm value,the LED always light.

*The smoke detector has good stabilization, false alarm is a little and it is not influenced by weather changing.

*No pollution, high safety

*Suitable spot:Stairway is very important for you to rush out when fires occur,so there must install smoke detectors.

In the circumstance where there are smog and steam resorting.
