Firebird V8-305 5.0L VIN E (1992)
Audible Warning Device: Description and Operation
CIRCUIT OPERATION
The Audible Warnings System sounds a chime to bring attention to one or more of several conditions. These conditions are: 1) the lights are on and the
Ignition Switch is not in RUN, BULB TEST or START; 2) the ignition key is in the Ignition Switch when the driver's door is open; and 3) the seat belt is
unbuckled when the Ignition Switch is in RUN, BULB TEST or START.
Voltage is applied at all times through the STOP HAZ Fuse to terminal C, to power the solid state Audio Alarm Assembly.
IGNITION KEY WARNING
Whenever the key is in the Ignition Switch and the Ignition Switch is in LOCK, OFF, or ACCY with the driver's door open, terminal B of the module is
grounded. This sounds the Key In Ignition Warning.
SEAT BELT WARNING
With the Ignition Switch in RUN, BULB TEST or START, voltage is applied through the GAGES Fuse to the Audio Alarm Assembly. With the driver's
Seat Belt unbuckled, terminal E of the module is grounded through the Seat Belt Switch. The SEAT BELTS Indicator always goes on for about 5
seconds when the Ignition Switch is set to RUN, BULB TEST or START. The Seat Belts Chime sounds, however, only if the Seat Belt is unbuckled
when the Ignition Switch is set to RUN, BULB TEST or START.
LIGHTS-ON WARNING
When the Light Switch is in HEAD or PARK, voltage is applied to the Audio Alarm Assembly at the Lights-On Signal. When the Ignition Switch is in
RUN, BULB TEST or START, voltage is applied through the GAGES Fuse to the Audio Alarm Assembly Power input. If voltage is applied only to the
Lights-On Signal, and not to the Power input, the alarm will sound. The voltage at the Power input, through the GAGES Fuse, cancels the alarm.
