COMPONENTS

The master caution system (see Figure 4-1)
contains the two annunciator panels, an elec-
tronic circuit-breaker unit, two MASTER
CAUTION lights, and up to 32 individual dim-
ming modules.
Electronic Circuit Breaker
(ECB) Box
This unit has 40 individual power outputs.
Two outputs power the 8 and 10 channel an-
nunciators. the other outputs provide power to
the dimming modules, which illuminate most
cockpit caution, warning, and advisory lights.
A failure of any of the 40 power outputs which
make up this ECB is indicated by the illumi-
nation of the Auto CB fail annunciator light on
the 10 channel annunciator panel. There is an
internal reset circuit which causes the annun-
ciator light to extinguish if the ECB is suc-
cessful in reestablishing power to that circuit.

Dimming Modules
The dimming modules provide interface be-
tween the airplane systems and the annunci-
ator panels. These modules are located under
the consoles in the cockpit. Each module is
powered by a separate channel of the elec-
tronic circuit breaker and routes this power to
the associated light groups. The modules each
have eight different channels that can be used
for illuminating lights.
The BRT-DIM switch is used to illuminate
most lights powered by the dimming modules
at either of two selected light intensities.

LAMP TEST SWITCHES

Lamp test switches (Figure 4-2) are located on
the 10-channel annunciator panel, the pilot's fas-
cia panel, the copilot's fascia panel, and the rear
of the center pedestal. All lights can be tested by
any of the three WARN LT test switches.
