26 Electronic Door Fittings of the PegaSys Series
Installing the lock cylinders
Insert the round cylinder from the inside and
fasten it.
Screw tight the door handle on the inside and the
fitting.
1.3.3 Function check - mechanical components
Check whether the gap between front metal and
striking plate is 2 to 5 mm .
With the key, check the "security function".
In a lock, the "security function" means that the latch
bolt can be retracted from the outside of the door by
means of the "key". This function is e.g. important if
no door handle is used on the outside of the door, but
instead a rigid knob. The latch actuation function
thus switches from the door handle to the key.
