A home communicator includes aid request circuitry capable of establishing communication with a central monitoring station in response to a first predetermined activation step performed by a subscriber and test circuitry capable of self-testing the home communicator in response to a second predetermined activation step formed by the subscriber. The home communicator further includes enable/disable circuitry capable of transmitting an identification number to a central monitoring station in response to a third predetermined activation step with the aid request circuitry and the test circuitry being unresponsive prior to the functioning of the enable/disable circuitry.
