A personal alarm system operative to provide a warning at a central monitoring station indicative of subscriber inactivity. The system comprises a subscriber station which interfaces to a communications link and a remote central monitoring station also interfaced to the link and operative to receive and analyze messages transmitted to the monitoring station by the subscriber station. The subscriber station transmits an alert message to the monitoring station over the communication link if the subscriber fails to reset clock logic via a reset switch or activity sensor within a predetermined time interval. An annunciator may be activated at the subscriber station coincident with transmission of the alert message. If the subscriber fails to activate a reset switch or a selected activity sensor within a predetermined period, the monitoring station provides an inactivity alarm indication to an operator who will take appropriate action. The system is primarily intended for the elderly, infirm, or incapacitated who are living alone and who, in event of illness or injury, might be unable to summon assistance and thereby suffer further harm as a result of inattention. The availability of this system will permit the aging and infirm to live independently without this fear.
