FIXING INSTRUCTIONS
Technical Data EMF
Operating voltage: 24 V DC
Power input: 1,4 W
Rated for continuous duty: 100 % ED
Release torque: approx. 25 - 65 Nm at an
opening angle of 90°
(dependent upon the
strength setting of the door
closer)
Door opening angle: max. 120°
The unit is controlled by an external smoke detector.
Installation on the pull side (hinge side)
Drill fixing points for closer and slide channel using
template TS 93 B or as per dimensioned drawing.
For electro-mechanical hold-open, wire in power
supply from the smoke detector.
Installation on the push side (opposite hinge side)
A separate approval certificate may be required in
conjunction with the fire/smoke door concerned ( e.g.
where DIN standards apply) – check local
regulations.
Drill fixing points for closer and slide channel using
template TS 93 G or as per dimensioned drawing.
For electro-mechanical hold-open, wire in power
supply from the smoke detector.
Install door closer and arm as specified in the fixing
instructions for the TS 93.
Lead the 24 DC cable through the end cap .
Insert end cap in the slide channel .
Fix the side channel .
Connect cable and stow in the hollow chamber of the slide
channel .
Connect the arm and slide shoe of the slide channel
as per TS 93 instructions, and adjust door closer
settings.
Setting the hold-open point:
Switch on power supply (24 V DC).
Open door leaf and engage hold-open. Loosen screws.
Open door to required hold-open angle and secure in
this position. Re-tighten screws.
The door cannot be opened beyond the holdopen
point; fix a door stop at this position.
Setting the pull-off force:
Adjust the pull-off force to suit the door width and
size of door closer.
EN 1155 states that the release torque at 90° door
opening angle should be between 40 and 120 Nm.
If the pull-off force is set too high, damage might
occur at the hinges and the fixings of the door closer
system.
Clip on end cap trims.
Break out marked recess in the cover and clip cover
into position.
Functional checks:
Open the door and engage hold-open.
Interrupt the power supply and ensure that the hold-
open mechanism releases the door.
