20 Operational topics
Low energy and full energy modes
ED100 and ED250 operator systems may be used in low
energy mode and full energy mode applications.
1. Low energy mode
Reference: Single door Installation Instructions manual,
Section 6, technical data.
The adjustable opening and closing speed range of door, and
door opening and closing torque, is restricted to certain limits.
Respective limits depend on actual door width and weight.
Depending on the application, door controlled by the swing
door operator may not need to be monitored by safety sensors.
2. Full energy mode
Reference: Single door Installation Instructions manual,
Section 16-U, Upgrade cards.
Requires full-energy upgrade card option. Due to high driving
speed of door, swing path must be monitored by safety sensors.
Safety sensors
Swing (hinge) side
Approach (opposite hinge) side
1. Safety sensors on swing (hinge) side
In case an obstruction is detected within detection range of
the safety sensors:
Door stops during its opening cycle.
Door, if closed, remains closed (does not perform an
opening cycle).
Operator will resume standard operation as soon as the
detection range is no longer obstructed.
2. Safety sensors on approach (opposite hinge) side
In case an obstruction is detected within detection range of
the safety sensors:
Door will reverse during closing cycle.
Door, if open, will remain open.
In manual mode, door stops.
Operator will resume standard operation as soon as the
detection range is no longer obstructed.
Manual locking of door
When door is manually locked,
operator program switches
must be set to OFF position in
order to avoid operator system
damage!
If an electronic lock with feedback device is installed, operator
will be switched off automatically.
Dorma recommends installation of an automatic lock
with feedback device.
Use with hold-open devices
1. When operator system is used at a smoke/fire door, it is
normally installed in conjunction with an electro-magnet
hold-open device (such as DORMA EM series).
2. With aid of hold-open device, operator holds door open
either:
Permanently – program switches are set to PERMANENT
OPEN.
Until expiration of adjusted hold open time – program
switches are set to AUTOMATIC.
3. Operation in event of a fire:
Door must close, or remain closed, to avoid smoke or fire
from spreading throughout the building.
As soon as one of the connected smoke detectors (or
building fire alarm system if connected) is triggered (fire
protection input at the operator), automatic opening
function of operator is deactivated and door will close
after a set period of time.
Hold-open device(s) are typically powered from a building
fire alarm system and / or local smoke detectors. When
fire protection input at operator is opened, hold-open
device(s) are deenergized.
From this point on, users can only open door manually.
4. Hold-open function is also deactivated whenever the
power supply is interrupted.
5. Manual triggering of hold-open device.
Apart from automatic triggering via a smoke detector, it
must be possible to trigger hold-open device manually
on site.
This allows users to close door in case of danger, even
before local smoke detectors, or building fire alarm
system, have been triggered.
How users can trigger hold-open device manually
depends on the connected accessories:
Pressing a red "Close door" pushbutton, located
within close range of door.
Closing door manually from its "open" position.
To deactivate the function manually, user
has to move door in closing direction by 10°,
which corresponds to approximately 4 - 8"
[10 - 20 cm] - depending on width of door.
