Abstract:
A system for transmitting and registering calls for assistance includes a plurality of call boxes, a central processor for receiving calls for assistance from the call boxes, and a plurality of portable radios capable of receiving paging messages from the central processor. At least one of the call boxes includes a frequency hopping spread spectrum transmitter for transmitting the calls for assistance, an actuator whereby a user can make a call for assistance, a voice message response device for providing a voice message, and a reset switch for resetting the call box. The central processor includes a transceiver for transmitting the paging messages, a receiver for receiving the calls for assistance, a memory and a processor. The plurality of portable radios may be carried by associates, whereby an associate may be notified of the call for assistance and report to the location. The voice message response device in the call box may verify to the user that the call for assistance has been transmitted, and may further instruct the user to remain at the call box until assistance arrives.
