The DT 700/DT 710 are intended for installation on wooden doors.
Prior to installing a DT 700/DT 710 on a door check the door to make sure it is
mounted correctly.
We recommend checking if the door design is suitable for use with a DT 700/DT 710.
Before a DT 700/DT 710 is installed on a fire protection/smoke control door check
the certification of the fire protection door on which the DT 700/DT 710 has been
tested, to make sure the DT 700/DT 710 is suitable for that particular door.
If door seals (e.g. sealing profile, floor seals) are used make sure that these don't
impede the correct function of the DT 700/DT 710.
The DT 700/DT 710 must be selected in the appropriate size (backset, forend width)
for the door leaf.
As a panic exit device class 2 (standard projection), the DT 700/DT 710 must be
used in places where the width of the escape route is limited, or where the doors on
which the DT 700/DT 710 is to be installed cannot be opened by more than 90°.
If the DT 700/DT 710 is installed on glazed doors, the glass parts have to be made
of safety glass or laminated glass.
The DT 700/DT 710 are not suitable for use on double action doors.
During the installation of the DT 700/DT 710 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 reduc-
tion of the height of the operating device should be considered.
When installing panic exit devices with lever handle activation (DT 700/DT 710),
in particular on doors with stepped surfaces, any possible safety risk, e.g. trapping
of fingers or entanglement of clothes, must 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 700/DT 710 intended for this purpose may
be installed to hold the closed in the closed position. This does not exclude the in-
stallation of door closers.
