Description
In the case of the fail-unlocked locking principle, the device is locked when an
electric current is flowing.
The lock pocket is the recess in the door or door frame to hold the lock.
The armature contact is a monitoring contact. The armature contact signals
whether the bolt is locked or unlocked.
The monitoring contact is a feedback contact. The monitoring contact signals
whether the door is closed with the lock sensor system detecting the proxim-
ity of the locking counterpart to the swing bolt.
The sensor system consists of a reed contact in the swing bolt and a trigger
magnet in the locking counterpart. If the lock is installed correctly, the reed
contact is triggered by the magnet when the door is closed.
The strike plate is used to fasten the lock into the lock pocket.
Moved by an electric motor, the bolt extends into the locking counterpart
recess and locks the door.
The locking counterpart is the counterpart to the swing bolt installed in the
door.
The rebate gap is the distance between the faceplate and locking counterpart.
