The HOMESAFE ® WIRELESS HOME SECURITY SYSTEM is a budget-friendly service to your office or home security requirements. This simple to run security system will sound an alarm and call as much as 5 pre-programmed phone numbers to let you know motion has actually been spotted or a door or a window has actually been opened in your house. A land line with tone dialing is required. HOW IT WORKS 1. When the door/window sensor or movement detector is activated, it sounds an alarm and sends out a signal to the base system. 2. The base system dials the very first phone number of your configured list. 3. The individual answering the call will hear a prerecorded alert message. 4. That individual will have the alternative to listen in on the room, broadcast their voice through the base system, or disarm the system. 5. If there is no answer, or if the individual does not disarm the system, it will call the next number on your programmed list. Includes 1 base system with Air Conditioner adaptor, 1 window/door sensing unit (wireless transmission as much as 250 feet), 1 movement detector (variety 8 yards) and 1 push-button control with panic function for equipping and disarming the unit. Extra Remote Controls HA-REMOTE $15.50.
