General information

An exit device complying with these European standards
always consists of (Fig. 1):
Mortise lock/Multi-point lock (active and/or passive leaf)
A
Door hardware (active and/or passive leaf)
B
Accessories (fixing material, square spindle, vertical rods,
C
passive-leaf control lock)
Keeper(s) (door frame, striker/latch&deadbolt striker,
D
passive-leaf lock, floor strikers).
Door closers and locking cylinders
E
required, but, if used, must be approved for use with the
appropriate exit device
(see www.g-u.com/de/downloads - Door Technology
- „Zulässige Schließzylinder in Kombination mit BKS-
Fluchttürschlössern" (permissible locking cylinders in
combination with BKS emergency door locks).
„ Only those devices are allowed to be installed which use components listed in the EC certificate of
conformity EN 179 or EN 1125. This also applies to the subsequent installation of spare parts.
„ Due to different frame designs, it may be impossible for the manufacturer to supply an appropriate keeper.
In this case the fabricator takes over responsibility, in agreement with the manufacturer, to design and
install an equivalent solution as demanded. See approved latch striker shapes (Fig. 3+4).
„ Before installing the exit device, make sure the door is properly installed and is not warped.
„ The deadbolt and vertical rods of the mortise lock and the additional latchbolts of the multi-points locks
must be received by the keepers freely without frictional resistance, even when load is applied to the door.
„ Also make sure that when retracted, the locking elements do not protrude so far as to obstruct the
movement of the door.
„ The exit device 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 exit device.
„ Make sure when using door gaskets that they do not impair the proper functioning of the exit device.
„ 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 exit device 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.
„ Check at double-leaf doors with rebated meeting stile 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 activating horizontal 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.
