Procedure 8.14: PERFORM COMMUNICATIONS MODULE/TIME-MULTIPLEXED SWITCH
FAN ALARM TESTS
OVERVIEW
CAUTION:
Do not remove fuses to simulate fan alarms. The RESET button on the fan unit power control board is
used to simulate a fan failure that results in system alarm responses.
This procedure checks the system responses for fan alarm circuits. The test provides for the fan alarms in the
communications module (CM) and the time-multiplexed switch (TMS). The test simulates a fan failure that causes a
momentary loss of power, by depressing the power
RESET
button on the fan unit control board. The exchange
indicators (alarms, reports, and display pages) are checked to verify the proper responses.
