Troubleshooting - Firecom pantherC Series Operation Manual

TROUBLESHOOTING

When properly installed and powered, a pantherC series intercom network will
perform reliably even in a harsh environment. If you believe one or more of your
intercom units are malfunctioning, use the following troubleshooting information
to locate the problem.
NOTE: This is a network communication system. Problems at one unit may affect
audio quality at some or all other units. Troubleshooting should include power and
network connections at all units.
If the symptoms you are experiencing are not covered in this manual, or if you are
having difficulty troubleshooting your system, contact your local Firecom dealer for
assistance, or see www.firecom.com for additional information.
Problem: One or more intercoms are not working.
• Check that the status light is on for each intercom.
If status light is out:
Check that the power switch is on (if it has one).
Check that the station has power. (See "Installation" section.)
Check that the network wiring is connected properly, and pay special attention
to correct termination. (See "Installation" and Appendix A – Network
Installation Tips.)
Problem: Cannot hear voice traffic on the speaker of an intercom.
• If there is a headset connected to the intercom unit, disconnect it.
• Adjust the volume control on the intercom.
• Be sure you are not pressing the PTT button while you are trying to listen.
• Check if other users can hear you talk on the intercom. If you can talk on the
intercom but can not hear through the speaker, the intercom is malfunctioning
and should be serviced by an intercom technician.
Problem: Cannot talk through the intercom microphone.
• If there is a headset connected to the intercom unit, disconnect it.
• Be sure to press the PTT button when talking from a base unit.
• If you are trying to talk on a remote unit, be sure you are speaking loudly
enough to activate the voice-activated microphone.
Can you hear traffic on the intercom through the speaker?
• If you can't talk or listen on the intercom, check the connection of the network
wires to your intercom unit.
