Personal radio alarm system - uses transceiver coupled to central monitoring station with facility for range of alarm routines

摘要

A personalised alarm system couples an individual with a central monitoring station with a transmitter-receiver. The signals from the transmitter-receiver are passed to the monitoring station containing a facility for timing signals and generating signals requiring a response. The system is readily adapted to allow the generation of a specific range of call signals, that in extreme cases provide automatic connection to the police services.
