INTERCOM CONNECTIONS
AUDIO MODULAR JACKS
On the rear of the intercom, there are 6 modular jacks under INTERCOM (Figure 7). These
REMOTE MODULAR JACKS
On the rear of the intercom, there are 2 modular jacks under REMOTE (Figure 7). These
jacks are for connecting CA Cables for the Remote Head(s). The CA Cables are all the same.
jacks are for connecting the CA Cables from the Headset Modules to the intercom. All of these
modular jacks will provide intercom and radio communication to the headset positions.
PRIORITY TRANSMIT
It may be desirable for one member of the crew to have priority for transmitting on the
radio. The audio modular jack closest to
AUX OUT
is the Priority Transmit Position
(Figure 7). Any headset position plugged into this jack will have priority for radio transmit
over all other headset positions. When the person in this position presses the PTT on the
headset,
ALL
transmissions from any other headset position will be stopped and the person
in the priority position will be able to transmit.
POWER CONNECTIONS
The 3010R Series Intercom requires at least +12 volts DC nominal (with a negative ground) at
.5 amps. This Intercom will accept DC voltage as high as 36 volts. The 3010R Series Intercom
comes with a Power Cable Assembly and a 1.0 amp, in-line fuse. We suggest connecting the
Intercom power and ground to the apparatus power buses.
RADIO INTERFACE
All Radio Interface cables are purchased separately.
ALL connections to the 2-way radio should be performed by a Qualified Radio Technician
to ensure proper interface between the 2-way radio and the 3010R Series Intercom System.

PR
There are many interface cables available from Firecom to interface the 3010R series intercoms
with specific radios. These custom interface cables will make interfacing the radio easier, but
should still be done by a qualified radio technician. Contact your local Firecom Dealer for more
information regarding the availability of an interface cable for your radio. The 3010R series
intercoms are compatible with radio interface cables used with the 3010 series intercoms.
If a radio specific cable is not available for a particular radio, a MR-0X cable will be required
to interface the radio and intercom. This cable is a 9-wire, shielded cable with a 9 pin D-sub to
connect to the intercom and unterminated wires to be connected to the radio.
