Place the wireless motion sensor module against a wall so it faces the direction of the window or door that will be protected by the wireless home alarm.
Mount the sensor module to the wall, using wood screws and a Phillips screwdriver. Plug the power cord into a wall outlet.
Open the control panel lid and adjust the setting knobs to sound an alarm immediately when movement is detected from the sensor. Also, set the unit so it will turn itself on when the sun goes down.
Close the lid and adjust the volume knob on the back or top fully clockwise. Place the wireless receiver on your night table. Plug the receiver's power cord into a wall outlet and turn on the receiver.
Press the "Sync" button on the side of the module and then on the receiver to sync the two together.
