Abstract
A personal emergency response system (PERS) is disclosed which includes a method and apparatus for monitoring alarm signals to provide improved emergency response capabilities and enhanced system operability. The system includes a local response center for relaying alarm signals received from subscribers to mobile on-site field personnel via individual paging units. The system is also capable of retransmitting an alarm signal in the event that a response to the original alarm signal has not been registered within a predetermined period of time. The system is also provided with redundant communications paths to minimize the possibility of a missed alarm message from a subscriber, and self-test capabilities for detecting system faults and transmitting fault messages to the individual paging units of the system.
