3.2.3 Wireless Door / Window Contact
Features
The door/window contact can be installed on doors, windows, and any other objects that open
and close. The sensor sends signals to the control panel when the magnet is separated from the
transmitter.
Thanks to the tamper switch, any attempt to remove the cover of the Door / Window Contact will
trigger the alarm.
When the sensor is in operation, if it is triggered
more than twice within 3 minutes, it switches to
standby mode to save power. If no movement
is detected within the next 3 minutes, the
sensor goes back to working mode.
Connect Button
Register in the control panel
Enter Connection Mode on the control panel. Press the connect button at the back of the motion
sensor or trigger the sensor (by moving in front of it).
Installation
Avoid mounting the detector close to windows, air conditioner, heater, refrigerator, oven, sunshine
and places where the temperature changes fast or where the air stream flows frequently.
If two detectors are installed in the same detection scope, adjust the location to avoid interferences
and false alarms.
Fix the bracket on the wall with screws
and attach the detector to the bracket.
Adjust the bracket to change the
detection distance and angle. It is
recommended to mount the detector
2,2 m from the ground.
