Operation - Firecom 210 Installation & Operation Manual

OPERATION

The 210 intercom is designed to offer clear, full-duplex communication between participants. In addition, mobile
radio communication is possible when connected to Firecom's 210 intercom.
Before testing the intercom, make sure the power supplied to the intercom is turned on. If a radio is connected
to the intercom, confirm that it has power as well.
To begin using the intercom, plug your Firecom headset into a headset module. For proper headset fitting
instructions, as well as care and maintenance, see your headset manual.
Firecom offers many different styles of headsets for use with the 210 intercom system including over-the-head
and under-the-helmet styles. Either of these styles can be intercom-only headsets or radio-transmit headsets.
Radio-transmit Headsets
Radio-transmit headsets are identified by a red momentary PTT button on the headset. These headsets receive
both intercom and radio communications at all times. The mic is always active for intercom communications,
while the red PTT button is used to transmit over the radio. When you speak into the microphone you will hear
yourself in the headset speakers. Volume is adjusted on the ear dome. You will hear other participants on the
intercom as well as radio traffic when a radio is installed with the system.
Intercom-only Headsets
Intercom-only headsets are identified with either a black momentary or yellow latching PTT button on the
headset. These headsets receive both intercom and radio communications at all times, but are not capable
of radio transmission. Headsets with black momentary PTT buttons require the user to push and hold the PTT
button to talk over the intercom. Headsets with yellow latching PTT buttons require a user to push the button
once to talk over the intercom and press again to end audio transmissions. When the PTT button is activated
and you speak into the microphone, you will hear yourself in the headset speaker. Volume is adjusted on the
ear dome. You will hear other participants on the intercom as well as radio traffic when a radio is installed with
the system.
Foot Switch (optional)
If an optional foot switch is installed, any headset plugged into the headset module attached to the foot
switch will transmit over the radio when the foot switch is activated. See System Wiring section, "Foot Switch
(optional)" in this manual.
When a mobile radio is connected to the intercom, radio traffic will be heard in the headset speakers. The volume
level of the radio traffic should be similar to the intercom audio volume level – see the Settings section of this
manual for adjustment.
One of the two headset intercom ports on the intercom is a radio transmit priority "PR" port – see the "CA
Cable Routing" in the System Wiring section in this manual. When a mobile radio is connected to the system,
the intercom user on this port will have priority when transmitting out the radio. Other users will not be able to
transmit over the radio once this user is transmitting.
