3.4 Activator
Activator, inside outside, night/bank and and intercom
system may be connected to the device. The activator inside
is usually found inside a building or room. The activator
outside is found on the outside of a building or room. The
activator night/bank is installed on the outside and often
designed as a card reader or key switch button.
3.5 Manual lock
If the door is closed manually, the drive must be switched to
the function OFF in order to prevent damage to the system.
If a door lock switch is installed, the drive function will
be automatically shut off.
DORMA recommends the use of a door lock switch.
3.6 Low/Full Energy mode
The drives ED 100 and ED 250 can be operated in the low
and full energy mode.
Low energy mode
The low speed of the door avoids most of the risk posed by
automatic movements. The door opens very slowly and offers
therefore superior safety.
Full energy mode
The high speed makes it necessary to secure the turning
range of the door with sensors.
Safety sensors mounted to the door panel monitor the
turning range and will prevent people from getting hit by the
door as far as possible.
3.7 Safety sensors
If the safety sensors on the hinge side detect an obstacle
during the opening, the door will stop.
If the safety sensors on the hinge side detect an obstacle
while the door is closed, the door will remain closed.
If the safety sensors on the opposite hinge side detect an
obstacle during the closing, the door will reverse.
If the safety sensors on the opposite hinge side detect an
obstacle while the door is open, the door will remain in the
open position.
If the monitoring range is free again, the drive will resume its
normal operation.
3.8 Maintenance interval display
If the internal 4-digit program switch is used, a service
interval display will be available. A yellow LED will inform
you about required maintenance work. The service counters
can be set by DORMA service personnel.
3.9 Use in a hold-open system
If the drive is used on a smoke control door or fire door,
the drive will usually be operated in a hold-open system in
combination with smoke detectors. The drive of the door will
keep the door open either permanently (PERMANENT OPEN)
or temporarily (AUTOMATIC). However, in case of a fire,
the door must close in order to prevent smoke and fire from
spreading. For this reason, the opening automatic of the
drive will be automatically shut off as soon as a connected
smoke detector detects smoke; this is indicated on the
smoke detector by a red LED. The door can then only be
opened manually. The hold-open function will be canceled
even if the power supply is interrupted.
Manual activation of the hold-open function
In case of danger, the door can also be closed manually -
either by pushing the optional red pushbutton with the label
"Close door" or by manually moving the door approx. 10-20
cm in the Closed direction.
Recommissioning the drive unit
In order to reestablish the drive function, the hold-open
system must be reset. In accordance with the legal
provisions, this must be carried out manually. The reset can
be carried out in different ways.
Reset via the door position
1.
Reset the smoke detector (LED display is green).
2. Completely close the door.
3. Open the door to the adjusted opening width.
4. Release the door.
Reset via the program switch
1. Reset the smoke detector (LED display is green).
2. Program switch in OFF and back.
Smoke control doors and fire doors are important for
your safety. However, this is only the case if the doors
will properly close in the case of danger. Therefore, do
not use additional wedges or objects that could prevent
the closing.
