The YD30S from BQT Solutions, also known as the Cobalt Single, is an advanced low-voltage, motor-driven door lock for pedestrian doors. Designed to secure single-acting doors, it resolves the two biggest issues in door locking: the ability to align a misaligned door and the ability to release when requested, even with pre-load load on the door. The unit seamlessly integrates into access control systems and can be mortice- or surface-mounted, making it ideal for use on glass doors. Made to exacting standards with full monitoring and user selectable fail safe or secure operation.
