Installation and Use of Door Sensor:

Door sensor is used in magnetic induction of close and open state, and is consisted of transmitter and magnetic. It can be installed on doors, windows or any object that can be closed and opened. When transmitters is separated with magnetic, door senser will send alarm signal to alarm panel, and host begins alarm siren.

The door contact should be installed on the movable door. Firstly, clean the corresponding position, and take out wireless door contact , then put on the double faced adhesive. The installation should note the items below:

1.The door sensor part A (transmitter) and part B (magnet) should be installed separately, that is, A on fixed door frame and B on movable door. ( the side with lights of transmitter should correspond with the magnet )

2. A and B should in the same vertical line and the distance between A and B should not greater than 1 cm. 

3. After the installation, the indicator light flashes for 1s as the door open, that means the door sensor is installed successfully.

4.The indicator light lit for 1 second, means alarm. The indicator in constant light is a suggestion of power lack. 

5.A, B can also be reinforced by screws, (A: remove the bottom cover, then screw in the bottom, buckle the cover to the bottom; B can be directly fixed on the screw back.)
