This heat detector is designed to detect ambient temperature.Generally it is connected with main controller.The main controller checks the current.When ambient temperature reaches preset value or the temperature flare to rise,the led indicates alarm and the current increase. The detector is suitable for industrial and civil building where there is explosive and combustible gas.

*Voltage:12V-30VDC

*Detecting method:rate of rise and reaching alarm temperature 65℃

*Two type optional:2 wire or 3 wire

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

*The power current should not exceed 30mA

*After installing and switching on power,the detector is in operation state.When it detects the ambient temperature is higher than preset alarm value or the temperature flare up to rise,the LED always light.

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

*No pollution, high safety

*Suitable spot:in the circumstance where there is smokeless fire and there are quantities of powder dust.Kitchen,boiler house,tea stove house,electrical machine house,drying workshop,indoor carbarn,smoking room,other rooms or public place where smoke detector is not fit to install.
