14.3 Important information on EN 179

The DT 600c FH is intended for installation on wooden doors and narrow frame doors.
Prior to installing a DT 600c FHon a door, check the door to make sure it is mounted correctly.
We recommend checking if the door design is suitable for use with the DT 600c FH.
Before a DT 600c FH is installed on a fire protection / smoke control door, check the
certification of the fire protection door on which the DT 600c FH has been tested, to make sure
the DT 600c FH is suitable for that particular door.
If door seals (e.g. sealing profile, floor seals) are used, make sure that these do not impede
the correct function of the DT 600c FH.
The DT 600c FH must be selected in the appropriate size (backset, forend width) for the door
leaf.
As a class 2 panic exit device (standard projection), the DT 600c FH should be used in places
where the width of the escape route is limited, or where the doors on which the DT 600c FH is
to be installed cannot be opened by more than 90°.
If the DT 600c FH is installed on glazed doors, the glass parts have to be made of safety glass
or laminated glass.
The DT 600c FH is not suitable for use on double action doors.
During the installation of the DT 600c FH, carefully observe the notes for fixing the terminal.
These instructions and all maintenance instructions must be handed to the operator by the
installer.
Generally, the operating device should be installed at a height between 900 mm and 1100 mm
above the surface of the finished floor, with the door closed.
If it is known that the majority of the users of the building are small children, a reduction of the
height of the operating device should be considered.
When installing panic exit devices with lever handle activation (DT 600c FH), in particular on
doors with stepped surfaces, any possible safety risk, e.g. trapping of fingers or entanglement
of clothes, should be avoided as far as possible.
The locking elements and locking counterpieces (striking plates) have to be installed in such
a way to make it safe to reach into the installation. It must be ensured that the projection of the
locking elements in retracted position does not hinder the free movement of the door.
No other devices except for the DT 600c FH intended for this purpose may be installed to hold
the door in the closed position. This does not exclude the installation of door closers.
If a door closer is installed to move the door to the closed position again, make sure that the
operation of the door by children and elderly as well as frail people is not impeded.
The provided locking counterpieces (striking plates) or panelling must be installed in order to
ensure compliance with EN 179.
