Hawker 800 XP, Pilot Training Manual

Page: 269 / 504

INTRODUCTION
The Hawker 800 XP fire protection system includes the detection and warning of fire
and overheat conditions in each engine and within the auxiliary power unit (APU).
Overheat detection capability for the rear equipment bay is also provided. Fire extin-
guishers are installed to extinguish engine and APU fires. A portable hand-held extin-
guisher is located within the cockpit for extinguishing a fire inside the fuselage.
GENERAL
The engine fire protection system is composed
of two sensing elements and responders per en-
gine, a warning indicator on the roof panel for
each engine, a warning bell, two fire extin-
guisher bottles which are activated from the
cockpit, and two fire detection circuit test
switches. The engine fire extinguishing sys-
tem is a two-shot system; if an engine fire is
not extinguished with actuation of the first
bottle, the second bottle is available for dis-
charge into the same engine. The engine fire
bottles are located in the rear equipment bay.
Exterior pressure relief discharge indicators
provide a visual indication if either fire bot-
tle has been discharged by thermal expansion.
The fire protection system for the APU in-
cludes three overheat detector switches, a
warning indicator light on the APU control
panel, the fire bell, one fire extinguisher bot-
tle which is activated from the cockpit, and a
FIRE detection circuit test switch.
Overheat detectors are installed in the rear
equipment bay. An indicator light on the MWS
panel is provided to warn of overheat conditions.
