The active leaf can be opened by the push bar at any time (panic function); in doing so, the spring-operated top latch is withdrawn through the spring-loaded rod; locking is done by key. With Series 23, locking is done by key. With Series 21, locking is done automatically without key. To ensure proper panic release, the key should always be removed.

Passive leaf
Inside
Active and passive leaf can be opened with the push bar at any time (panic function on both leaves). Upon closing, the passive leaf is locked automatically via the vertical rods. If the door is opened by the passive leaf, the carrier bar ensures that the active leaf is taken along, as far as to activate the door leaf coordinator, so the leaves can close in the appropriate sequence. Moreover, the leaves cannot jam, not even with a small clearance. The closing sequence of the door is controlled by the door leaf coordinator integrated in the door closer.
