detecting temperature method: rate of rise and fixed temperature
* alarm temperature:65℃
* static current:40μA~80μA
* working temperature:－10℃~+50℃
* working humidity:10~90%
* installing method:ceiling installation
*The power current should not exceed 30mA
*After installing and switching on power, the detector is in operation state. When it detects that the ambient temperature is higher than preset alarm value or the temperature flare up to rise, the LED light indicating alarm.
