Characteristics ／
1.There are two LEDs which can turn 360o and watch the    situation of the detector at any angle. 2.Joint functioning way: NO type and NC type. 3.The use of common base is advantageous to the     exchange of detector.
Functioning way／
As there is smoke getting in the detector, by making use of the scattered rays caused by the reflection of smoke, the rays can be detected by the luminous two-node substance inside the device. Then the detector functions and sends out alarm. Meanwhile, the LED is turned on. It is suitable for installation at the places like the entrance of staircase, corridor, lift hall, indoor room, etc.
