DIN EN 179
The DT700/DT710 is designed for installation on wooden doors.
Before fitting a DT700/DT710 to a door, the door should be checked in order to en-
sure that it has been properly hung.
It is advisable to check whether the design of the door allows the DT700/DT710 to
be used.
Before a DT700/DT710 is fitted to a fire/smoke door, the certification of the fire door
on which the DT700/DT710 was tested should be checked in order to ensure that
the DT700/DT710 is suitable for this particular door.
If door seals are being used (e.g. profile seals, floor seals) it should be ensured that
they do not impede the proper operation of the DT700/DT710.
A suitable size of DT700/DT710 (backset, forend width) for the door leaf must be
selected.
The DT700/DT710 as a grade 2 emergency exit device (standard projection) should
be used in cases where the width of the escape route is limited, or the doors to which
the DT700/DT710 is going to be fitted cannot be opened by more than 90°.
If the DT700/DT710 is fitted to glazed doors, the glazed parts must be made from
tempered safety glass or laminated glass
The DT700/DT710 is not suitable for use on double action doors.
The installation instructions must be carefully followed during the installation of the
DT700/DT710. These instructions and all maintenance instructions must be passed
on to the operator by the installer.
The operating element should normally be installed at a height of between 900mm
and 1100mm above the surface of the finished floor with the door closed.
If it is known that the majority of users of the building will be small children, reducing
the height of the operating element should be considered.
All potential safety risks such as trapping fingers or snagging clothing should be
avoided to the maximum extent when installing emergency exit devices with lever
handle operation (DT700/DT710), particularly on doors with raised or recessed sur-
faces.
The bolt heads and keepers (strikes) must be attached in such a way that access
can take place safely. It must be ensured that the projection of the bolt heads in the
withdrawn position does not impede the free movement of the door.
No devices other than the provided DT700/DT710 must be installed for securing the
door in the closed position. This does not exclude the installation of self-closing de-
vices.
