Transcript HC-202D Ionization Smoke Detector

Characteristics ／
1.Has monitoring function. The LED flashes once
every 4 ~ 6 seconds.
2.There are two LEDs which can turn 360o and watch the
situation of the detector at any angle.
3.It provides the wiring (-R) function of entrance LED.
4.The use of common base is advantageous to the
exchange of detector.
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.
