Function of the single-leaf version
When the door closes, all latches and the main deadbolt automatically extend.
The door is opened from the inside using the lever or panic push bar, and from the outside with the cylinder key.
At panic function B the exterior lever-handle can be activated or deactivated via the cylinder key.
Function of the double-leaf version
When the door closes, all latches and the main deadbolt automatically extend and are sucured against being pushed back. Unimpeded escape to the outside, using the lever or panic push bar on either the active or inactive leaf, is however assured. When the inactive leaf is opened in an emergency, the rods of the drive locks are retracted from the keep and, at the same time, all of the locking elements in the active leaf are pushed back. The round rods of the inactive leaf automatically latch in this position. Only when the passive leaf is closed, does a switching lock automatically trigger locking the rods at the top and bottom.
