Check hook operation
As stated, the latches are the compression
points and when the trigger is depressed and
the hooks drop, the hooks should not come into
contact with the keeps. Please ensure that the
door is fully closed, to check that the hooks are
correctly fully engaged. However, it is important
that the door is pushed or pulled fully closed to
check the hooks are fully engaging.
Remove the tape temporarily holding the
hooks. Close the door until it latches and fires
the hooks and centre deadbolt. Unlock the door
by rotating the thumbturn cylinder away from
the lock jamb.
Setting the latch operation
In order to ensure that the door latches
correctly, it is important to temporarily disable
the hooks. To do this, please use a piece of tape
placed over the hooks aperture on the face bar,
to hold them into the retracted position. It is
also important that compression of the gaskets
is achieved on the latches only. The hooks and
deadbolt are security measures and should
operate “in fresh air”.
With the hooks disabled, please close the door
until it latches. Check that the leaf is flush with
the frame on the opening side of the door. If you
need to adjust the keep for compression, then
open the door and adjust the roller plates on the
centre keep first by undoing the adjustment
screws and moving the plates until you achieve
a smooth latching operation. Repeat the
process on the top and bottom hook keeps until
the desired compression is achieved.
Please note: Contact of the hooks with the
keeps will result in increased operating forces
and therefore, a stiff key operation.
