ABSTRACT:
A security system which includes remotely controlled entrance monitors (12) to indicate when an intrusion has occurred, an arming/disarming control (18), a console (14) responsive to the entrance monitors and arming/disarming control, and an alarm (16) responsive to the console for audibly indicating intrusion. These components are completely wireless with one another. Radio coded signals are transmitted between components requiring a coded combination between the console and entrance monitors, and a coded combination between the console (14) and alarm (16) and arming/disarming control (18). The arming/disarming control (18) includes an arming button (20) for arming the system and a disarming button (22) for disarming the system with a slideable protective cover thereover to prevent accidental depression of either button.
