The ABUS FAS97 additional lock is intended for securing the hinge side of a window. You should secure the opening side separately. Locking is automatic so there is no need to activate the additional lock manually. When you open the window, the FAS97 moves with it; to tilt the window, simply push the hinged bar to the side. The hinge side lock is mounted on the casement and on the frame. Because it locks automatically when the window is closed, the lock is always engaged.
