The model 842 is an electromotive swing bolt, which both pivots the bolt outwards and retracts it by means of a high motorised force. The bolt moves into the striking plate with a V-shaped cutout. This has the advantage that the bolt can also be pushed out if the striking plate and bolt are not in a fully aligned position. The motorised power cam bolt is the lock with fail-unlocked function, which means the unlocking takes place by spring power in the event of a power failure. The swing bolt can be installed concealed within the door frame or door leaf.
