Alarm Module Smoke Sensor, Smoke Sensor, DC 9V Photoelectric

Size: 70 mm X50mm X20mm length * width * height

Second, the main chip: smoke sensor probe

Three, working voltage: DC 9 v

Four, features:

1, with a relay control output;

2, working current is small, low power consumption, induced current 30 ma, standby current: 10 ua;

3, with level detection alarm signal output can be effective control;

4. A copy of the power supply can be directly use DC9V batteries;

5, induction, high sensitivity, low rate of false positives;

6, effective insect resistance, resistance to dust, resistance to light effect, long service life;

7, large detection area, easy installation

Five, the application:

Suitable for residential home or commercial, such as indoor and outdoor smoke detection.

Module wiring label details:

GND - connect power anode

VCC - connect power anode

OUT - the default level signal output low level (smoke) output level is detected

K - often start relay output

G - relay output public side

B - relay output normally closed end

Test method:

3 s 1, hold down the test buttons, lights start flashing, relay suck together, often beginning with the public through.

2, blowing smoke into the maze, about 3 s lights began to twinkle, relay or absorption, relay often start with the public through;
