Section III - SYSTEMS DESCRIPTION
ANNUNCIATORS
The lighting intensity control for the MWS annunciators is provided by a dimmer and a switch located
on the center instrument panel. A MWS DIM FAIL annunciator is positioned at the top of the left
instrument panel. The MWS ANNUN test push switch is located on the test panel at the top of the
overhead roof panel and will illuminate most of the annunciators at full intensity. For details of the
operation of annunciators associated with the master warning system, refer to Sub-section 1 - MASTER
WARNING SYSTEM.
The lighting control of the MWS annunciators is by variable dimming effected by a rotary MWS DIM
control in conjunction with a NORM - DIM OVRD switch. Should the dimming circuit fail, resulting in loss
of light to the annunciator, the NORM - DIM OVRD switch may be selected to the OVRD position; this
effectively bypasses the dimming circuit and connects a 28 VDC supply direct to the annunciators. Both
power supplies are taken from the PE busbar.
The flight annunciator illumination intensity is controlled by the ANNUN BRT/DIM switch located on the
left side glareshield panel. This switch also controls the landing gear and wheel brake emergency
annunciator illumination levels.
