Why is there a hum or buzzing noise in my Greyfox Cat 5 Intercom System?
A hum or buzzing noise in your Greyfox Intercom System might be due to several reasons. Ensure you're using the correct power supply for your intercom system size. Check that the wiring guidelines have been followed. Also, make sure all Cat 5 cabling doesn't run parallel to AC power lines within 12 inches and avoids fluorescent lighting fixtures and dimmer switches.
How to stop feedback or squealing from Greyfox Cat 5 speaker?
To eliminate feedback or squealing from your Greyfox Intercom System, first, check the unit placement. Avoid placing units back to back on a common wall. If units must be placed on both sides of a common wall, ensure the audio from a unit’s speaker isn't audible to a nearby unit’s microphone. Another solution is to adjust the volume of the unit from a high level to a medium level.
How to troubleshoot no power to Greyfox Cat 5?
If there is no power to any unit of your Greyfox Intercom System, check the Intercom Module power LED to verify that it is lit. If it's not lit, ensure the power transformer or power distribution module is plugged in. Also, verify that you are using the correct 12 V power supply or power distribution module for your system. If you are not using a 12V power transformer that supplies enough current to the system, the unit may not power on.
What to do if a specific Greyfox Intercom unit has no power?
If a specific Room Unit, Door Unit, or Main Console Unit of your Greyfox Intercom System has no power, check your terminations at both the punchdown block on the rear of the unit itself and the RJ45 connector which plugs into the Intercom Module. Verify that your terminations follow the T568A wiring standard. If your wiring terminations are in the correct order based on the color (T568A), then re-terminate your cable at both the rear of the unit and at the Intercom Module. You can also check and see if the unit will power on by plugging it into a different port on the Intercom Module.
What to do if third door unit is not functioning properly on Greyfox Cat 5 Intercom System?
If a third Door Unit is not functioning properly on your Greyfox Intercom System, verify that the third Door Unit is plugged into the port on the Intercom Module that is labeled 12/DOOR 3. By default, the 12/DOOR 3 port on the Intercom Module is configured to operate a Room Unit. To use a Door Unit on this port, you must first remove the shorting block which is installed on the top two pins of the pin array labeled JP100 on the rear circuit board of the Intercom Module.
