Schlage Electronics M490DE Electromagnetic Lock, 1500 lbs Holding Force, Delayed Egress
electromagnetic locks provide breadth of application, depth of features and a proven record of performance.
The Schlage M490DE delayed egress electromagnetic lock is designed to meet NFPA 101 Life Safety Code while providing the same robust, easy-to-install, security of our M400 Series magnetic locks. The M490DE has a 15-second delayed egress timer with audible alarm which can be configured to trigger by an internal "plunger switch," or by external contacts, such as a request-to-exit push bar.
