INTERCOM CONNECTIONS

MODULAR JACKS
On the rear of the intercom, there are 6 modular jacks (Figure 7). These jacks are for con-
necting 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 modular jack closest to the power connector 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 3010 Series Intercom requires +12 volts DC (with a negative ground) at 0.25 amps. The
3010 Series Intercom comes with a Power Cable Assembly and a 1/4 amp, slo-blo, in-line
fuse. We suggest connecting the Intercom power and ground to the apparatus power busses,
preferably to the same connection points as the radio.
RADIO INTERFACE
A universal Radio Interface Cable is supplied with the 3010 Series Intercoms. This cable is
a 9-wire, shielded cable which terminates with bare wires.
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 3010 Series Intercom System.
There are many different interface cables available from Firecom to interface the 3010 Series
Intercom with specific radios. These "dedicated" 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.
