Emir Software: AN Overview

An intercom capability is added to a basic radio telephone system by configuring the base station to function as a radio repeater for inter-active communication between a telephone/intercom handset and an intercom unit. A distinctive intercom ring signal permits a user to switch the handset to the intercom mode. Activation of the intercom receiver and transmitter on a timed basis limits battery drain. A purchaser, after setting up the base unit, need only position the intercom unit adjacent to a residence entry. Since no intercom wiring is required, the telephone/intercom is immediately ready for use with minimal installation. The base unit is also configured to prevent intercom access to or from the public telephone network.
