To open the door from the inside of the property
Lift the handle at the rear of the case to with draw the lockbolt and move the door in the opening direction.

2. Insert the key in the inside cylinder and rotate to the stop.

To open the door from the outside
Insert the key in the outside cylinder and rotate to the stop. Move the door in the opening direction whilst holding the bolt in the withdrawn position with the key until the autobolt projects and the lockbolt is held in the withdrawn position. Closing the door will automatically release the lockbolt and secure the door in the locked condition.
It should be noted that this lock has a safety feature whereby the action of re-entering the premises will automatically release the locked inside handle thereby returning the lock to normal operation.
To hold the bolt in the withdrawn position
- Lift the handle to withdrawn the bolt.
- Push on the button whilst pushing the bolt into the case until the button enters a small amount into the lock.
The bolt will now be held in the withdraw position until the button is pulled out.
Indicator Mechanism
To provide awareness of the state of security this product is fitted with an indicator that provides a simple but effective indication of the state of locking.
For maximum security the indicator must be flush with the surface of the lock when the door is closed. This shows that the lockbolt has fully thrown and the deadlocking mechanism is fully in place. If this is not so, examine the staple box to ensure that this is clear to obstructions and if necessary reposition the staple to ensure freedom for the bolt to enter.
It should be noted that this product has a secondary standby position whereby the deadlocking can take place when the bolt has thrown half way. This will be indicated by the indicator projecting half the full amount. Whilst this provides a degree of security the above procedures should be followed to achieve maximum security.
