Benefits and features common to the single-point locks in 3/4-point locking versions.
All effeff multi-point lock models are also available with an integrated latch bolt lock 807 in the face plate and an integrated escape door strike 331® in the striking plate. Thus they also comply with the complex security requirements of doors on escape routes.
In emergency situations, the panic function enables the door to be unlocked at any time using the inside handle or the panic bar. Manipulation and attack attempts against one of the bolts, do not affect the other bolts.
A further special feature of these multi-point locks is that they can be upgraded to include a fourth bolt. Intrusion protection requirements can thus be met even with extremely tall doors.
