B. Troubleshooting Guide
Problem Solution
No power to any intercom unit
-Check Intercom Module power LED to verify that it is lit.
If not, make sure power supply is plugged in.
-Verify that you are using the correct 24V power supply
for your system by obtaining the model number and
calling your On-Q installer or On-Q Technical Support.
No power to a specific Room Unit, Patio Unit, or
Door Unit
-Check the Cat 5e cable terminations at both the rear of
the Unit and at the Intercom Module. Verify that your
terminations follow the T568A wiring standard.
-If your wiring terminations are visibly correct according
to the T568A standard, test the conductivity of the
connections, and re-terminate if a problem is found.
-Check to see if a Unit will power on by plugging it into a
different port on the Intercom Module.
Feedback or squeal noise from a Room Unit, Patio
Unit, or Door Unit speaker
-Verify Unit placement. Avoid placing Units back to back
on a common wall. If Units must be placed on both sides
of a common wall, do so in a manner which avoids
feedback problems, ensuring that the audio from a Unit’s
speaker will not be audible to a nearby Unit’s
microphone.
-Feedback issues can normally be eliminated by
adjusting the volume of a Unit from a high level to a
medium level.
Hum or buzzing noise that can be heard in some or
all units of the Selective Call Intercom System
-Verify that the proper wiring guidelines, found in this
manual, have been followed.
-Verify that Cat 5e cabling does not run parallel to and
within 12 inches of AC power cabling. Also avoid running
Cat 5e cabling near florescent lighting fixtures, dimmer
switches, or fan controls.
