The Wireless Home Security System consists of a main control unit with a 105 dB alarm, one door/window sensor, one motion detector sensor and a remote control with panic button. The instructional DVD makes it easy to install.

You can also install the control unit and use the remote panic button to notify someone in case of an emergency. This is an ideal use for elderly people who live alone.

1. You program your cell phone and additional emergency contact phone numbers into the main control unit. When the door/window sensor or motion detector is triggered, it sounds an alarm and sends a signal to the control unit.

2. The control unit dials the first telephone number of your programmed list.

3. The person answering the call will hear the pre-recorded alert message.

4. That person will have the option to listen in on the room, broadcast their voice through the control unit, or disarm the system.

5. If there is no answer, or if the person does not disarm the security system, the unit will dial the next number on your programmed list.

You can also install the control unit and use the remote panic button to notify someone in case of an emergency. This is an ideal use for elderly people who live alone.

The main unit can accommodate up to 14 additional sensors for expansion. Door window sensors and motion detector sensors are also sold separately.
