M490DE Delayed Egress Electromagnetic Lock, Satin Aluminum - Schlage Electronics

Product Overview

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. All M400 series electromagnetic locks are symmetrical with field-selectable handing, allowing optimum placement of the magnet no matter the application. They are designed to provide automatic voltage sensing for 12 and 24 volts along with polarity protection to make wiring less complex. "Plus" models offer magnetic bond sensor (MBS), adjustable relock time delay (RTD) and door position switch (DPS). Bayonet mount simplifies installation by eliminating the need to hold lock overhead while securing. Armature mount pivot feature compensates for slight opening imperfections.
