Using your Door Sensor

1. Dry clean the installation area. Remove the protective layer of the double-side tape of

the Sensor’s Part A and B. Simply stick the two parts on the door and door frame.

Please ensure that the horizontal installation gap between two parts is less than or

equal to 5/8 inches.

* Please stick the sensor indoor, and do not use the sensor with iron door. The two small

marks that both parts have on the side should be facing each other, that is, almost in

contact。
