TROUBLE SHOOTING
Fault: Volume Control at Master does not adjust music level on a 6-wire system.
Fix: The conversion to 6-wire at the Master is achieved not by programming, but by fitting
wire links between the COM1 to MUS1 and COM2 to MUS2 terminals. Ensure Master is
programmed to 8-wire.
Fault: On a 6-wire system Music mutes when the talk button is pressed but returns as
soon as the talk button is released.
Fix: For 6-wire systems, music is transmitted on the same cables as communication
therefore music must be muted throughout the system whenever communication takes
place. To achieve this, ensure the jumper is fitted to both the link pins labelled L1 on the
Master Audio Interface PCB or the Auxiliary Input Jack for Room Station only systems.
Fault: House and door talk functions work correctly but no communication using numerical
private dialling.
Fix: Ensure Room Stations have been coded correctly and all stations are set to either
single digit or double digit dialling format.
Fault: Music and monitoring is not being received at certain Room Stations although
communication is being received okay.
Fix: Ensure that all stations are correctly programmed to either 8-wire or 6-wire
(Master must be programmed to 8-wire in all cases).
Fault: No communication or chimes, on a "Room Station Only" system.
Fix: - Ensure load resistor is fitted to system.
- Make sure the load resistor is not shorting against the speaker when the fascia is
attached to the Room Station.
- At all stations, ensure the VLC and TC wires are in the correct terminals and have
not been reversed.
- At all stations, ensure that there are no exposed wires at any terminals.
Fault: No communication or chimes on a "Master" system.
Fix: - At all stations, ensure the VLC and TC wires are in the correct terminals and have
not been reversed.
- At all stations, ensure that there are no exposed wires at any terminals.
