Lock case LC100

Lock case with an automatically deadlocking latchbolt. 

The lock must always be equipped with handles, as the latchbolt is retracted with the handles only.

The deadlocking is controlled by a snib in the forend. 

When the snib is in deadlocking mode, the door is opened by turning the outside key 180° or the inside thumbturn 90°. 

The handles are then activated, and the latchbolt can be retracted.

Snib position:

UP = Deadlocking, latchbolt protrudes 21 mm.

The lever handles are activated by the key or the thumbturn.

DOWN = Latchbolt protrudes 14 mm. 

The door is opened with the lever handles.

The lock case LC100 is fitted with a feature to prevent  unauthorized use of the snib.

The snib is locked to the deadlocking mode by turning a set screw, located below the snib, about two turns anticlockwise by a hexagonal key, until the screw stops and is opened by turning the screw clockwise.

LC100X is the microswitch version of the lock.

The switch changes it’s status when the bolt has protruded to 21 mm.

Following striker plates are recommended to be used with a microswitch locking box: 4692, 4693.
