1.Joint functioning way: NO type and NC type.
2.There are two LEDs which can turn 360o and watch the situation of the detector.
3.The use of common base is advantageous to the exchange of detector.
4. Functioning way: as there is smoke getting in the detector, the ion current will be decreased, making the voltage increase and touching the detector to function and send out alarm. Meanwhile, the LED will be turned on automatically. Under normal situation, the LED has monitoring function. And as it functions, the LED keeps turning on continuously. It is suitable for installation at the places like the entrance of staircase, corridor, lift hall, indoor room, etc.
