The YML-650B is an electromechanical mortise lock with an adjustable operating mode, designed for single or double-swing doors. In fail-secure mode, the device can also be mechanically unlocked with a key in case of an emergency. The locking mechanism is compatible with EUROPROFILE lock cylinders.
When the door is closed, the mechanism automatically locks the latch. It also features status feedback: when the door is closed and the latch is locked, it provides NO/NC feedback.
During installation, ensure the correct positioning of the device—the lock cylinder must always be at the top.
To reverse the operating mode, always follow the steps in the datasheet precisely and without omission.
