Schlage Electronics M490P Maximum-Security Electromagnetic Lock, For Access Control Systems, Single Door, 1,500-lb. Holding Force

The Schlage M490P maximum-security electromagnetic lock meets or exceeds Builders Hardware Manufacturer Association (BHMA) 1,500-lb. hold force requirements, can connect to an access control system, and connects to a door access system such as a push bar, request-to-exit device, or credential reader to create a secure locking system for a single inswing or outswing door. The electromagnet mounts to below the top of the doorframe using the included bayonet mounting bracket that enables hands-free installation of the magnet. The armature attaches flush against the door and pivots to compensate for slight irregularities. 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). 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, and the automatic surge suppressor protects the equipment from damage if voltage spikes. The lock housing has a satin chrome finish and has a symmetrical design that allows for both right and left hand installation. When used with an access control system, the lock's door-status and magnetic-bond sensors communicate with the system to identify if a door is open or closed and to monitor the strength of the magnetic connection to ensure a strong door hold. The lock can be programmed with a 0.5- to 30-second relock delay. Two locks can be combined with a connector block (sold separately) to create a locking system for double doors.SpecificationsHolding force1,500 lb.Specifications metLock meets ANSI/BHMA 156.23, UL1034, and UL10C specifications.

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.Schlage Electronics, an Allegion brand, manufactures security products for commercial and residential use.
