Place the sensor in the area of the home where you would like to install it. If you have a ceiling sensor, use your power drill to drill in the screws on the included mount on the ceiling, then slide the sensor into the mount.
Position the sensor so the eye of the sensor has a clear field of view to the area you would like to monitor.
Plug the power cable running from the sensor into an available wall outlet.
Power on your central keypad and enter the sync code found in the user manual for the particular model sensor that you have just set up.
Set the alarm the same way you would normally do it and the sensor will now be included in the system. You can also manually turn the sensor on and off via the "Power" button on the front of the sensor.
