INTRODUCTION
Overview
The Fire Research ICA700 intercom is designed to meet rescue and fire service
requirements for a two, three, or four-way voice communications system. (More than
four intercom boxes can be connected when using the ICA700.) The hands free intercom
system is weather-resistant and specifically designed for outside use on fire service
apparatus. A high level output signal ensures high quality sound even when the wires
are routed through an aerial turntable.
The ICA700 hands free intercom is voice activated. When power is applied the
intercom is in receive mode. To talk on the intercom the operator speaks and the intercom
automatically switches to transmit mode.
There is a rocker switch on the bottom of each standard station box so it can be
set to hands free or PTT (Press-To-Talk) mode. The PTT indicator LED will flash to
indicate that the PTT mode has been selected. In this mode the PTT switch on the
station box must be pressed to transmit.
Two optional configurations are available:
PTT (Push-To-Talk) Only - The PTT button must be pressed to transmit. There
is no mode selector switch or indicator LED on this station box.
Hands Free Only - The station box is always in transmit mode unless interrupted
by a transmission from another station. There is no mode selector switch, PTT
button, or indicator LED.
