 The door is locked with a hook on the upper section of the door.
 This hook is attached to the locking shaft with a rod and a bellcrank.
 An arm on the locking shaft gives a visual indication.
 A spring rod holds the door in the locked position.
 A safety pin stops the door if there is a malfunction of the locking
 mechanism or the lifting mechanism.
 The inner and outer control handles are slaved to one another by a
 gearbox assembly.
 The gearbox assembly is attached to the locking shaft and the reducer
 shaft. It stops the outer handle when the door is released with the inner
 handle.
 When the door closes, the inner control handle puts the outer control
 handle in its housing through the gearbox.
 When the door is open, and in the up position, a safety pin prevents the
 gearbox from turning.
 The door is immobilized in the up position when the lowering shaft no
 longer touches the stop fitting on the frame.
 The compensation mechanism is a torsion bar. It enables easy opening and
 closing of the door by weight compensation when it is released.
 The force that is necessary to release the door must be equal to or less
 than 16 daN (35.9694 lbf)

 B. Escape slide control mechanism (Ref. Fig. 003) The escape slide is installed on the bottom of the door. When the emergency control handle is in the armed position, the escape slide girt bar engages into the fittings on the door threshold. It is stowed on the door when the emergency control handle is in the DISARMED position

 A housing installation that contains a cam-disk and a roller attaches the escape slide control lever to the outer control handle. It disarms the escape slide automatically when the door is opened with the exterior control handle. The escape slide control mechanism puts the escape slide control lever in the DISARMED position when the door is not fully closed and locked. A hook prevents arming of escape slide when the door is open. A spring rod and a hook are attached to the locking shaft with a rod. The locking shaft locks the escape emergency handle in the DISARMED position. The escape slide inflation mechanism is a striker attached to the bellcrank assembly on the escape slide control mechanism. When the emergency control handle is put in the ARMED position, the striker turns about its axis and moves under the striker mechanism attached to the damper and emergency operation cylinder. The emergency control handle is in the ARMED position. A visual indicator is installed at the forward end of the girt bar. There is a special "wiper" ring on slide flexible controls. The special ring reduce the control loads of flexible controls under adverse freezing conditions.
