Modular Cables; Interface Connections; Intercom Unit - Firecom 3000A Installation & Operator's Manual

3000A
If you wish to have an uncovered plug-in module near a
pump panel, for example, FIRECOM has a waterproof en-
closure available. The modular connectors used in the
system are gold-plated to resist corrosion. The cabling
may be installed on the surface, or you may choose to hide
it behind panels, headliners, door sills, etc. Protect any
cabling run through bulkheads or other sheet metal by use
of grommeted holes to prevent damage to the cables.
Prior to securing the system components in place, verify
the layout for:
• Control accessibility
• Headset storage
• Headset cable reach
• Interconnect cable length
• Ease of installation
Stow any excess cable length behind panels or other out-
of-the-way locations. Additional interconnect cables may
be ordered from FIRECOM if needed.
Headset modules may be daisy-chained to the same
intercom connection, but multiple headsets on one
chain may reduce the received audio. This permits
multiple location use of each intercom channel.

Cables are fabricated at the factory in set lengths. Do
not cut these cables unless you are familiar with phone
plug crimping techniques and have the proper tools.
Additional cables may be ordered from FIRECOM if
needed.
Read the Pre-Installation section before attempting
installation. All cables should be installed prior to final
placement of other system components. Be sure to have
all system component locations pre-selected and
Observe that there are three INTERCOM/TRANSMIT
ports and three INTERCOM ONLY ports at the rear of
the Intercom 3000A (see photo). In a typical installation
this would allow the Officer, Engineer/Driver, and Pump
Panel positions to be connected to the INTERCOM/
TRANSMIT side and the jumpseat positions to the IN-
TERCOM ONLY side.

The Intercom 3000A includes a 25-pin connector and
interface cable for connection to the fire apparatus. Con-
nections to power and to the radio are made through this
cable. We recommend that these connections be made
by a qualified radio technician.
