Abstract
An intrusion detection system can be armed and disarmed from a plurality of remote locations by the use of a plurality of momentary switches, each one associated with one of said locations. Each switch when depressed, functions to change the state of a flip/flop. The flip/flop in one mode operates to disarm the intrusion detection system. When the flip/flop is in its other mode, the intrusion detection system is armed and activated. The apparatus monitors the state of the control loop associated with the detection system in order to indicate to a user that the system can be activated or armed when desired. If the control loop is not secure, the apparatus will indicate this fact to the user to enable him to secure the loop before arming the system by triggering of the flip/flop.
