Standard electric strike with rounded and adjustable latch (FF, FaFix).
Fail locked operation.
The door can only be opened while a contact is made. In alternating current operation, a humming noise is audible. In direct current operation, there is no noise. When mounting with a throw-open spring or throw-open bolt, the door is opened visibly after a contact is made.

During the opening procedure the latch turns back into the lock case, thus the usual door frame cutout at the latch is not needed.

Compatible with all common standard striking plates.
DIN right and left installation thanks to 180° rotation.
Symmetrical structure.
