Single-leaf escape doors

In single-leaf doors, the lock variant is used without an unlocking pin. When using the lock variant with an
unlocking pin in a single-leaf door, the unlocking pin has no function.

Double-leaf escape doors

The security lock 309N with unlocking pin in the bolt (Fig. 5) is installed in
the active leaf in a set of double-leaf doors.
There is an passive leaf lock with unlocking mechanism ("Accessories",
page 56) in the inactive leaf which can push in the unlocking pin and
then the bolt.
In this manner, the locked escape door can be unlocked and opened with
the door handle or panic bar of either door.
