Schlage – M490DE Delayed Egress Electromagnetic Lock

The Schlage M490DE delayed egress locking system is designed to meet NFPA 101 Life Safety Code, while providing the same robust, easy-to-install, security of our M400 Series line of electromagnetic 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 an request-to-exit push bar.

All M400 Series locks have automatic voltage sensing for 12 and 24 volts along with polarity protection to make wiring less complex. The M490DE is tested and certified to meet or exceed UL special locking arrangements and BHMA 1500 lb hold force requirements.

The M490DE electromagnetic lock comes in two configurations to meet your specific security needs. The M490DE provides basic security and delayed egress functionality, while the M490DEP provides intelligent sensing and reporting features needed to integrate with access control systems.

This easy-to-install, cost effective solution provides the highest access security and safety.
