Advanced Delayed Egress Security for High-Risk Commercial Openings

The Locknetics® M490DEP Delayed Egress Electromagnetic Lock is a powerful, commercial-grade delayed egress locking solution engineered to secure controlled exit points while maintaining compliance with life safety and fire safety requirements. Designed for demanding access control environments, the M490DEP combines 1500 lbs of holding force, intelligent monitoring capabilities, integrated alarm functions, and delayed egress technology to help deter unauthorized exits, reduce theft, and improve perimeter security management.

Ideal for healthcare facilities, retail environments, educational campuses, warehouses, commercial office buildings, and institutional facilities, the M490DEP provides a controlled egress delay that helps prevent unauthorized departures while still allowing safe emergency exit operation. Once activated by the internal plunger switch or auxiliary input, the lock initiates a 15-second delayed egress cycle, providing audible and visual warning alerts before releasing the door.

Built for advanced monitored access control systems, the M490DEP includes integrated DSM (Door Status Monitoring) and MBS (Magnetic Bond Sensor) technology to deliver real-time feedback regarding door position and magnetic lock bond integrity. These monitoring capabilities improve system reliability, simplify diagnostics, and provide enhanced security visibility for facility managers and integrators.

The Locknetics M490DEP also features dedicated fire alarm input, release input, and reset input connections, allowing seamless integration with fire alarm systems, emergency release circuits, request-to-exit devices, delayed egress controllers, and centralized access control platforms. Automatic Voltage Selection (AVS) simplifies installation by automatically detecting operating voltage requirements during setup.

Engineered for professional installation and long-term durability, the M490DEP incorporates a rugged aluminum housing with a 628 satin aluminum finish, along with a convenient bayonet mounting system that eliminates the need to hold the magnet overhead during installation. The armature pivot feature further enhances reliability by compensating for slight door and frame imperfections to ensure consistent magnetic contact and holding performance.

Whether securing retail exits, pharmacy doors, memory care units, emergency exits, inventory-controlled areas, or high-traffic institutional openings, the Locknetics® M490DEP delivers dependable delayed egress protection, advanced monitoring functionality, and enterprise-level electromagnetic locking performance.
