8.6.6 FAULTS
Viewing of Failures (from the OPERATOR menu)
The OPERATOR menu provides access to the “FAULTS” panel, as
illustrated in the “FAULTS” section of the <INSPECTION> menu.
The additional function enabled on accessing the “Report>
FAULTS” panel from the OPERATOR level is “Manual Resetting
of a Failure Signal”.
8.6.6.1 Manual Resetting of a Failure Signal (RES)
Manual Resetting is necessary in the following cases:
• To reinstate operation of a speaker output line following
detection of a failure due to a short circuit (SHORT A, SHORT B
or SHORT A+B).
• To cancelled a stored RES (RESOLVED) signal following
detection and subsequent clearing of a failure, for all the other
items being monitored.
To RESET the FAULT signalling manually, from the general FAULT
display panel, access each of the following display panels by
pressing the corresponding numbered key:
1- LOUDSPK. LINE FAULT
2- VOICE ALARMS FAULT
3- AMPLIFIER FAULTS
4- POWER SUPPLY FAULTS
5- CONTROL INPUT FAULT
6- COMMUNICATION FAULT
• Press the RESET key.
Upon completion of the procedure, press the ESC key repeatedly
to return to the OPERATOR menu.
8.6.6.2 Restoring the 6-zone configuration
In a 12-zone system, when the REMOTE LINK between two
VAIE 2250 units connected to one another fails, the REMOTE
LINK FAULT is signalled.
To clear this fault signal and restore the normal configuration,
access the “FAULTS” panel from the OPERATOR Menu. Press key
2 to go to the “VOICE ALARM FAULT” panel, then press RESET.
The FAULT LED will extinguish to indicate that the fault is no longer
present.
Repeat the procedure on both VAIE 2250 units.
