The Schlage GF3000BRD DSM MBS bottom-rail mortise-mounted shear electromagnetic lock with 3,000-lb. holding force and status sensors creates a fully concealed locking mechanism that connects to an access control system such as a keylock or keypad. The electromagnet installs into the floor and the armature mounts into the bottom of the door or bottom rail to The door-status and magnetic-bond sensors identify if a door is open or closed and monitor the strength of the magnetic connection to ensure a strong door hold. The lock can be used for both inswinging and outswinging doors that do not have the top clearance for air adjustment and are recommended for doors that are wood framed or hollow metal with a hollow frame. An access hole enables air gap adjustment from the side. The locking tabs on the electromagnet hook into the armature's grooves for additional security when locked. The automatic voltage selection feature distinguishes between either a 12- or 24-VDC electrical connection and adjusts the lock automatically, eliminating the need for field adjustment when voltage changes.
The lock housing has a satin aluminum finish and has a symmetrical design that allows for both right and left hand installation. The integrated door-position switch prevents relocking before the door is back in position. The lock can be programmed with a 0- to 30-second relock delay. The magnet portion is active when connected to a power source, and it loses its magnetic hold and unlocks the door when power is removed either with a door access system such as a push-to-exit button or by power outage (also called a fail-safe design).

Electronic door locking systems use electric current to control and secure access. Entry is regulated with a door access device such as a keypad or a reader that limits entry to authorized users. Some systems can designate user access for specific hours or days and may include a keyway for mechanical override. Common electronic locking mechanisms include electromagnetic locks and electric strikes. These systems are hardwired or battery powered, which is suitable when electrical wiring is not readily available. Locks are available in cylindrical and mortise styles. A cylindrical lock requires two bored perpendicular holes in the door for installation: one in the door face and a crossbore hole in the door edge. A mortise lock fits into a pocket recess in the door edge.
