Installation instructions - Door sequence selector SR 2000
INSTALLATION
Important: The minimum width of a door leaf is about 750 mm. For doors with less than 1000
mm width per leaf you need to choose the short version of the SR 2000 door sequence selector
(hatched area). Exception: with door leaves 100 mm-thick the short type can be used up to
900 mm door width only.
1. Fit the door sequence selector from below to the frame with two M5x30 hexagon socket
screws. Make sure the door sequence selector runs parallel to the door. The front edge should
be about 1 mm from the door leaves.
2. It is important that in its upright position the telescopic arm hits the active door leaf at exactly
90°. This angle can be adjusted with a screw at the bottom of the telescopic arm. With doors
made of thin sheet steel we recommend using a reinforcement plate in which the telescopic
arm hits the leaf (the distance to the pivot point of the door is approx. distance X less 65 mm).
3. The roller on the release arm can be adjusted by an eccentric screw, so that the passive leaf
closes completely and the telescopic arm folds up entirely.
4. Remember to tighten the counter nut again.
5. After installation, check the proper function of both arms and the adjustment of the angle of
the arms.
Important installation advice
When fitting the selector, both washers furnished along with the selector have to be inserted
between the casing of the selector and the door frame to avoid any twisting between frame
and casing - see drawing.
Max. torque when tightening the screws: 4.5 Nm (If the screws are tightened too much, the
casing of the selector might be slightly distorted and thus a proper function of the selector be
prevented.)
The function of the selector might be impaired by exterior influences. That is why it must not be
painted, plastered of modified in any way.
