Installation on double doors
If the operators are to be mounted at the same height with pushing and pulling arm systems, the
height is determined by the pulling arm system, PULL. The pushing arm system PUSH must always
have a shaft extension, minimum 50 mm, maximum 70 mm to match the mounting heights visually.
Example: if PULL has a 20 mm extension, the PUSH must have a 70 mm extension. If PULL has 0 mm
extension, the PUSH must have a 50 mm extension.

How to cut the jumper on the sync cable for double doors
Note! Connect a cable between primary CU and secondary CU.
Primary
Note! The connection/marking of the sync cable determines which of the operators is the primary
and secondary.
For a Rebated door;
• the Primary door must open before the secondary door
• the secondary door must close before the Primary door

Double door installations
There are four different types of double door installations:
• Rebated Has an overlapping primary door, can be opened synchronously if it is not jamming
and must be closed asynchronously to avoid that the doors will jam or close in the wrong order.
• Jamming This door type needs to be opened and closed asynchronously to avoid that the
doors will jam with each other.
• Not jamming, not rebated This door type has doors that always can move independently of
each other and can be opened and closed synchronously.
• Double egress This door type has doors that opens in different directions which can be opened
and closed independently. This door type may have a different way of handling safety sensors
due to the difference in opening direction of the doors.
