Security Door Opener 12V

The door opener latch with lock bolt catcher holds the lock bolt when the door is closed. While the door opener coil is energised, the opener latch is movable and the door is released.

When the door is opened, the door opener latch is turned open by the lock bolt and remains in this state. When the door is closed again, the pre-closed lock bolt turns the lock bolt catch with the door opener latch back into the locked position. When the safety pin is sufficiently actuated, the door opener locks and the door is secured again. The safety pin ensures that the electric strike does not lock when the electric strike latch is turned back manually.

The door can only be opened during contact (power supply to the electric strike). In the event of a power failure, the door remains locked. It is then only possible to open the door by manually unlocking the bolt lock via the locking cylinder or key.

Feedback function

The model RR AK RR provides two messages about its functional status:

The changeover-controlled feedback contact (RR) reports the door status "open" or "closed" with a potential-free changeover contact. The microswitch is controlled by the change in the door opener. The message "locked" is only given when the latch of the dead bolt door opener is brought into the locked position by the lock bolt and the safety pin is sufficiently actuated by the lock bolt. (Change in the locked position) Closing back of the lock bolt with the door opener locked is not detected.

The armature switching contact (AK RR) signals the locking status of the electric strike with a potential-free change-over contact. This signalling contact is controlled directly by the armature of the electric strike. With AC operation of the electric strike coil, the armature is set into oscillation by the changing magnetic field at the moment of unlocking; this also affects the armature contact. This behaviour must be taken into account in the design of the monitoring circuit.

Der wechselgesteuerte Rückmeldekontakt (RR) meldet den Türzustand „geöffnet“ oder „geschlossen“ mit einem potentialfreien Wechselkontakt. Der Mikroschalter wird durch den Wechsel im Türöffner gesteuert. Die Meldung „verriegelt“ erfolgt erst, wenn die Falle des Riegelschlosstüröffners durch den Schlossriegel in die Verriegeltposition gebracht ist und der Sicherheitsstift ausreichend vom Schlossriegel betätigt wird. (Wechsel in der Verriegeltposition) Das Zurückschließen des Schlossriegels bei verriegeltem Türöffner wird nicht erkannt.

Der Ankerschaltkontakt (AK RR) meldet den Verriegelungszustand des Türöffners mit einem potentialfreien Wechselkontakt. Gesteuert wird dieser Meldekontakt direkt durch den Anker des Türöffners. Bei Wechselstrombetrieb der Türöffnerspule wird im Moment des Entriegelns der Anker durch das wechselnde Magnetfeld in Schwingung versetzt, dies wirkt sich auch auf den Ankerkontakt aus. In der Auslegung der Überwachungsschaltung muss dieses Verhalten berücksichtigt werden.

The door opener latch with lock bolt catcher holds the rigid lock bolt when the door is closed. During energisation of the door opener coil, the opener latch is movable, the door is released.

The electric strike SB 312 is designed for deadbolt locks with a maximum deadbolt dimension of 65 x 18 mm. Wherever the installation of a motor lock is not possible for technical or structural reasons, the electric strike can be used with a mechanical deadbolt lock.
