Information
Intended use
The security lock 309N is suitable for installation in single-leaf tubular frame or solid-leaf doors (backset 55
mm or greater) made of metal, plastic or wood.
It is designed to provide door locking in security areas and is approved for use in escape doors according
to DIN EN 179 and panic door locks according to DIN EN 1125.
· With two-leaf escape doors, the inactive leaf must also be designed as an escape door and must be
equipped with an approved passive leaf lock ("Accessories", page 56).
· If the inactive leaf is not designed as an escape door, the security lock 309N may only be installed in the
two-leaf door when the inactive leaf can be securely held in place with zero play and the active leaf runs
against a stop edge.
With double-leaf doors with rebated meeting stile and panic locks in each leaf, the leaf must open when
the panic door lock is actuated. Both leaves must open freely if both panic door locks are actuated at the
same time. This may require a door coordinator to be installed.
For double-leaf doors with rebated meeting stile and door closer, the correct door closing sequence must
be assured; otherwise the function of fire doors or smoke protection doors, in particular, is not guaran-
teed. It may be necessary to install a follower.
It is suitable for use on fire doors (smoke protection doors). All applicable provisions for the approval of
protective doors must be observed.
The security lock 309N may only be installed in properly functioning door systems. All applicable regula-
tions for the complete door system must be observed.
The device is suitable for installation according to the installation instructions and use according to the
functional description.
The security lock 309N is suitable for installation in doors with a high usage frequency for use by persons
with little reason to take care, where there is the possibility of an accident or misuse (such as office doors).
It is not intended for any other type of use.
