ESCRIPTION
The production auxiliary annunciator panel has been replaced with a new panel which adds the following
new switches:
•
CABIN TEMP - COCKPIT/CABIN
•
CALL RESET - CABIN/LAV
•
ENTRY LIGHTS - ON/OFF
•
SMOKE DET TEST
The CABIN TEMP switch allows the cockpit crew to transfer control of the cabin temperature to the cabin
switch panels. The CALL RESET switch illuminates when a CALL switch is pressed in the cabin or
lavatory and allows the cockpit crew to reset the call system. The ENTRY LIGHTS switch allows the
cockpit crew to turn the entry lights on or off. The SMOKE DET switch allows the cockpit crew to test the
lavatory and baggage compartment smoke detectors.
A new annunciator dim/test unit has been installed to provide additional power and test functionality for
the backlighting of switches installed in the cockpit during the completion process. The
production-installed IND LTS DIM/BRT switch provides dim/test control of the original aircraft system
and the added annunciator dim/test unit.
