SECTION 3
AURAL/VISUAL WARNING SYSTEMS
GENERAL There are two aircraft central warning systems, the aural warning system, which provides audible tones associated with seven significant events, and the master caution and warning system which advises the crew of system malfunctions*
AURAL WARNING SYSTEM (Figures 1 and 2) The aural warning system monitors seven events and provides a separate aural warning for each event, as follows: EVENT TONE TEST SWITCH AURAL WARNING
Engine fire FIRE Fire Bell
Overspeed OVSPD CI acker Airspeed too high for flap setting FLAP OVSPD Wailer Stall STALL Warbler Incorrect take-off configuration TOC Intermittent horn Altitude alert ALT-ADV C chord Landing gear not down and locked LDG GR Horn The system consists of two main components, an aural warning unit and an aural warning test panel• The aural warning unit has seven tone generators. Depending on the event, one of the tone generators is triggered. The output is fed via amplifiers to the pilot1s and copilot's headphones and to the flight compartment speaker system. The aural warning test panel has a TONE TEST switch, a PRESS TO MUTE switch and a VOLUME CONTROL. Setting the TONE TEST switch to the selected position triggers the associated tone generator. When the TONE TEST switch is set to the FIRE or FLAP OVSPD positions, the tone can be muted by pressing the PRESS TO MUTE switch which also causes the TONE MUTED light to come on. When the TONE TEST switch is set to the STALL, TOC, ALT-ADV, LDG GR or OVSPD positions, the tone cannot be muted by pressing the PRESS TO MUTE switch and the TONE MUTED light does not come on. The aural warning system can be tested by selecting each event, in turn, on the TONE TEST switch. The VOLUME CONTROL adjusts the audio output level.

MASTER CAUTION AND WARNING SYSTEM (Figures 3, 4, 5, 6 and 7) The master caution and warning lights provide a visual indication to the pilot and copilot of an aircraft system malfunction. Safe indication and advisory lights provide a visual status indication of aircraft systems. A specific fault is indicated by an individual system warning or caution light and, for a caution light, also by a system legend on the 10-channel or 8-channel system annunciator panel and by two flashing master caution lights mounted on the glareshield. Warning lights (red) that may require immediate action by the flight crew are not annunciated and do not trigger the master caution light flasher. Caution lights (amber) that may require future action by the flight crew are divided into two groups, annunciated and not annunciated. Safe indication and advisory lights (white or green) are not annunciated and the colour of the light varies with the light function. When either MASTER CAUTION PRESS TO RESET switch/light is pressed, a reset signal is sent to the 10-channel and 8-channel system annunciator panels and the annunciated legend and master caution lights go out, thus arming the system to display a subsequent fault. The individual system light remains on and only goes out when the fault is cleared.
If the TEST-RECALL switch is set to RECALL after reset and the affected system annunciator legend comes on again and both master caution lights flash a fault is still present.
When the TEST-RECALL switch is set to TEST, all legends on the 10-channel and 8-channel system annunciator panels and the master caution lights come on.
The BRT-DIM switch on the 10-channel system annunciator panel controls the brightness of both system annunciator panel legends, the two master caution lights and all individual system lights.
Four test switches allow all warning lights to be tested. The switches are located as follows:
TEST/RECALL on 10-channel system annunciator panel - WARN LTS TEST on pilot's facia panel - WARNING LT TEST on centre pedestal WARN LTS TEST on copilotfs facia panel
Figure 8 shows the locations of the warning lights tested by each switch,

OPERATING MANUAL
An electronic circuit breaker unit completes the system. The unit contains 40 protected 28-volt dc power supplies for the master caution and warning system and other flight compartment warning lights. Each power supply is fed from three separate sources:
- BATT BUS, CBP-B
- 28V DC ESS BUS, CPD-D
- 28V DC BUS 2, CBP-B Each output is automatically scanned to detect any possible overload, indicating a fault in one of the channels. When a fault is detected the AUTO CB CHAN FAIL annunciator comes on. The unit operates individually or simultaneously from the three power sources.
