ENGINE FIRE DETECTION
Each engine fire overheat detector system is
connected to an associated ENG FIRE warn-
ing light on the FIRE panel, an associated
ENG FIRE repeater light on the MWS panel,
the MWS flashers, an HP cock warning light,
and, via a relay, a warning bell. Bell operation
may be canceled by setting a switch to BELL
CNCLD (Figure 4-2).
Each detector circuit is provided with a FIRE
warning TEST push switch. Pressing the
switch operates the associated warning system.
LANDING GEAR HORN
WARNING
The horn gives a continuous steady note when
the gear is in any position other than down and
locked and the flap handle is in landing or ap-
proach position. On the ground, with the land-
ing gear down and locked, the gear selector
lever out of the down position, and start power
selected, the horn also sounds. In either cir-
cumstance the horn cannot be overridden.
AIRBRAKES HORN WARNING
The horn gives a continuous steady note if the
gear is down and locked, both throttles are
above approximately 60-70% N
1
rpm, and the
airbrakes are open.
THROTTLES BELOW
60%–70% N
1
RPM
When the landing gear is in any position other
than down and locked when either throttle is
moved below approximately 60-70% of N
1
rpm, and the airspeed is below 150 knots, the
horn will emit a continuous steady note.
Operation of the horn CANCEL button (Figure
4-3) on the No. 1 throttle lever interrupts
power to the horn. The horn remains silent
until the throttles are both above approxi-
mately 60-70% N
1
rpm or the airspeed is above
150 knots.
