Also make sure that, when retracted, the locking elements do not
protrude so far as to obstruct the movement of the door.
 
The locking system must operate smoothly and easily.
If it does not move easily, this could be a sign of incorrect assembly or
locked-up stress in the locking system.
 
Make sure when using door gaskets that they do not impair the proper
functioning of the locking system.
 
Due to the design, other hole diameters or fixing types than those
described which are not compatible with our fixing materials may be
required. The fabricator is responsible for verifying that the lock has been
fastened correctly in these cases and they therefore do not constitute
part of these assembly instructions.
 
To guarantee a secure fixing, a through-fixed screw connection is the
most recommended installation.
 
On double-leaf doors with a rebated meeting stile, make sure that each
leaf opens individually when the corresponding panic exit device is
actuated and that both leaves open when both locks are operated at
the same time. To ensure the door functions correctly, use of a carrier
bar and a door leaf coordinator (to EN 1158) is recommended to ensure
the doors are not restrained and also close in the correct sequence. This
particularly applies for fire/smoke protection doors.
 
The horizontal activating bar must normally be installed at a height of
900-1100 mm above finished floor level (FFL) with the door closed so as
to achieve the greatest possible effective bar length.
If most of the users are small children, lowering the installation height of
the activating horizontal bar should be considered.
 
To hold the door shut, no other devices than those approved to EN 1125
should be installed.
However, this does not exclude the use of door closers.
 
When using a door closer, it must be ensured that the door closer does
not prevent children or elderly or infirm persons from operating the door.
