Sensors are essential to protecting your home.They should be installed on doors and windows that are easily accessible from the outside, especially on the ground floor. Entry Sensors are made up of two parts: a magnet to install on your door or window, and a sensor to install on the doorframe or window frame. However, depending on your home, the installation of your Entry Sensor may be different. The most important part of installation is making sure that the magnet aligns between the two grooves on the sensor, and that they are less than two inches apart from each other when the door or window are closed.
If you open a door or window with an Entry Sensor installed on it the sensor will flash a blue status light once indicating that the magnet and sensor have been separated more than two inches. The sensor will flash the blue status light twice when you close the door or window, and the magnet returns within two inches of the sensor.
Opening a door or window that has an Entry Sensor installed on it will also trigger the Base Station to make a chime sound when the system is disarmed. If your system is armed, and an entry sensor is triggered the alarm will sound.
To install your Entry Sensor pull the white battery activation strip hanging from the sensor’s battery compartment. Next, remove the liner from the adhesive strip on the sensor’s bracket, and adhere it to the corner of your doorframe or window frame. Press and hold the sensor for 30 seconds to ensure it is firmly attached. If you would prefer a more secure installation, slide the sensor up off of it’s bracket, and screw the bracket into the doorframe or window frame. Once you have finished securing the bracket slide the sensor back on to the bracket, and it is installed. Repeat these steps with the magnet, however you will be installing the magnet on the door or window. Remember the magnet must align between the two grooves on the sensor, and they should be less than two inches apart when the door or window are closed.
