Abstract

A multi-state selection switch for a personal emergency response system which permits selective operation of the system in HOME or AWAY modes. In the HOME mode, a subscriber unit located in a remote subscriber station is activated by a subscriber using either a portable or wired-in activator to transmit an alarm message to a central station via an interconnecting communications link. In the AWAY mode, the subscriber unit is inhibited from activation as a personal emergency response system by the protable activator and may be interfaced with one or more funtional subsystems of the remote subscriber station and operative to perform one or more predetermined regulating and/or monitoring functions in combination with the corresponding interfaced subsystems. The subscriber unit in the AWAY mode may be operative to transmit status messages to the cnetral station. Also, while the system is in the AWAY mode, the portable activator can be used for command or control purposes without causing an alarm to be transmitted. Upon return of the subscriber to the remote subscriber to temporarily deactivate the subscriber unit, thereby permitting the subscriber to enter the remote subscriber station and selectively switch the subscriber unit to the HOME mode.
