    Overview

    The Schlage M490DE is designed specifically for delayed egress applications and meets NFPA 101 Life Safety Code. 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. Standard features include automatic voltage selection, field-selectable handing, internal plunger switch, and bayonet mounting bracket for easy hands-free installation. The "Plus" model adds intelligent sensing and reporting features needed for integration with access control systems.

    All Schlage electromagnetic locks come with a limited lifetime warranty on the magnetic coil assembly for added confidence in the longevity of these robust products.
