3. Description___________
R
R The emergency exit doors (referred to as doors) are installed with the
R support arm on the related hinge fittings of the fuselage. Each door has a
R locking mechanism to release or lock the door and to operate the lifting
R mechanism. The lifting mechanism moves the door up so that the lateral guide
R rollers come free from the fuselage guide fittings. The balance mechanism
R decreases the force necessary to operate the locking mechanism.
R
R Each door has an escape-slide release mechanism which operates the automatic
R inflation system (ATA Ref. 25-62-00). There are two operation modes for the
R escape slide-release mechanism:
R - the DISARMED MODE for the operation during maintenance,
R - the ARMED MODE for the operation during the flight.
R The DISARMED MODE prevents the operation of the escape-slide release
R mechanism when the door is manually opened.
R
R When the door is unlocked from the inner side of the cabin in the ARMED
R MODE:
R - the emergency operation cylinder opens the door in its fully open position
R within 10 seconds,
R - the escape slide-release mechanism operates the automatic inflation system
R which inflates the escape slide below the applicable door.
R When the door is unlocked from the outer side, the ARMED MODE of the escape
R slide-release mechanism changes automatically to the DISARMED MODE.
Two proximity sensors and their targets monitor the UNLOCKED/LOCKED
condition and the DISARMED/ARMED mode of the door. One proximity sensor
which is part of the Escape Slide-Warning System (circuit WN) transmits a
signal to the Electronic Centralized Aircraft Monitoring (ECAM) System. It
indicates a warning in the cockpit on the lower ECAM display panel when a
person tries to open the door in the ARMED MODE. At the same time the white
indicator light SLIDE ARMED located near the door window comes on. The other
proximity sensor is part of the Door Warning System (circuit WS) and also
transmits a signal to the ECAM system. It shows on the lower display panel
that the door is unlocked.
An additional proximity sensor and its target are installed in the fuselage
above the door. This sensor is also a part of the Door Warning System
(circuit WS) and monitors the OPEN/CLOSE position. When the switch mechanism
