For G - SR without electro-mechanical hold-open
(EMF), skip to step 10
Install interconnecting cabling supplied
7
(shortening as necessary)
Ensure that the cable does not come into contact
with any moving parts and that it is not caught inside
the connecting rod.
Connect the cable as follows:
EMF - inactive leaf
24 V DC - from RMZ smoke detector or smoke
detector by others
E = Limit switch - this releases the inactive leaf when
the active leaf is pulled off/released from its
hold-open position.
8
Setting the hold-open point
GSR-EMF 1
The hold-open point of the inactive leaf is adjustable
between approx. 80° and 130°. The active leaf is held
open by the door co-ordinator.
GSR-EMF 1G
The hold-open point of the active leaf is adjustable
between approx. 80° and 130° (inactive leaf cannot
be held open).
GSR-EMF 2
Both hold-open points can be adjusted independently
of one another between approx. 80° and 130°.
Switch on power supply (24 V DC).
Open door leaves and engage hold-open
Loosen screws
Open door to required hold-open angle and secure
Re-tighten screws
The door cannot be opened beyond the hold-open
point; fix a door stop at this position
9
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.
Functional checks:
GSR EMF 1, GSR EMF 2:
Open both door leaves and engage hold-open.
Then pull the active leaf closed.
The inactive leaf must be automatically released and
closed.
The active leaf should also close automatically once
the inactive leaf has reached its closed position.

Open active leaf and engage hold-open.
Open inactive leaf and engage hold-open
(not EMF 1G).
Interrupt the power supply and ensure that the hold
open mechanisms are released.
The active leaf should also close automatically once
the inactive leaf has reached its closed
position.

Clip on end cap trims.
Break out marked recess in the cover and clip cover
into position. Ensure that the cover provides a flush
closure with the end cap trims.

saw to size.
Clip on cover and plastic jointing elements.
