IF THE SYSTEM DOES NOT OPERATE
AS EXPECTED, CHECK THE FOLLOWING
ITEMS FIRST
• Check that the apparatus master switch is on.
• Check the fuse or circuit breaker.
• Check system wiring and interconnections.
• Check the orientation of ALL RJ-12 Modular Connectors on BOTH ends of each
CA Cable. See "Modular Plug Installation" (page 21).
• Check that the headsets are plugged in all the way.
• Check intercom and headset control settings.
• Check for corrosion on headset plugs.
• Check that the headsets are plugged into the proper locations. A Radio-Transmit
Headset MUST be plugged into an Intercom/Tx port. An Intercom-Only
Headset will NEVER transmit on the radio.
If these steps do not correct the problem, continue with the advanced troubleshooting
procedures on page 27. If you cannot find a section relating to the symptoms you are
experiencing, or if you need assistance, contact your local Firecom Dealer.
TROUBLESHOOTING A HEADSET LOCATION
This procedure will help determine if a problem exists in a particular headset location, and
which component in the headset location is faulty.
1. Examine the headset's label to determine if the headset is an Intercom-Only
Headset or a Radio-Transmit Headset.
• If the headset is a Radio-Transmit Headset, the speakers should always be
active. The mic should always be active, pressing the red PTT button on the
ear dome should key the radio only if that headset location is plugged into an
Intercom/Tx port, otherwise the PTT button will have no effect.
• If the headset is an Intercom-Only Headset, the speakers should always be
active. The mic should be active only when the black or yellow PTT button
on the ear dome is pressed. The headset should never cause the radio to key
when installed in any headset location.
2. Plug the headset into another good headset location.
• If the headset fails to perform properly in the new location, the headset is
faulty. Contact Firecom for a Return Authorization to return the headset for
repair.
