The SR 90 door sequence selector remains unfolded when only the finally locking leaf is opened. Every time both door leaves are opened the telescopic arm of the SR 90 door sequence selector is automatically set in an upright position by the integrated leg spring.

Montage
Montage-instructies
First, fix both support brackets to the upper middle corners of both door leaves with the included hexagon socket screws (M8x16 DIN 7991). The exact dimensions for the position can be found on the dimensioned drawing.
Then, screw the door sequence selector to the door frame with the included M8x16 hexagon socket screws. The countersunk head screw should go into the hole with countersink, the cylinder head stud should fit into the oblong hole. Please make sure that the door sequence selector runs absolutely parallel to the door lintel when closed. You can adjust the horizontal position by loosening the M8 cylinder head stud in the oblong hole and moving the base of the door sequence selector slightly around the countersunk head screw.
