Sdc 101-DENA Delayed Egress Controller Nfpa Exit Device

Product Description

The SDC - SECURITY DOOR CONTROLS 101-DENA is a delayed egress controller designed for use in access-controlled door systems that must comply with NFPA life-safety requirements. Delayed egress hardware introduces a timed delay before a secured door can be opened during an egress event, providing both security and code-compliant emergency exit capability. This controller is the core timing and control component in a delayed egress assembly, managing the delay sequence, alarm output, and door release functions. It is typically specified and installed by licensed security integrators, access control technicians, or low-voltage contractors working on commercial door hardware projects.

The 101-DENA is suited for commercial and institutional applications where perimeter door security is required alongside life-safety egress compliance. Typical installations include retail loss-prevention doors, stairwell and exit corridor doors in healthcare or education facilities, and secure areas requiring monitored egress. This controller integrates into a complete delayed egress system alongside the appropriate locking device and egress sensing hardware.

Key Features

• NFPA-compliant delayed egress control for life-safety door assemblies
• Manages timed delay sequence and door release for compliant egress events
• Designed for commercial and institutional perimeter door security applications
• Sold as a single unit for direct integration into a delayed egress door assembly

Compatibility

Designed as an OEM-style controller for use in delayed egress door assemblies meeting NFPA life-safety egress requirements. Consult the product manual and door hardware schedule for specific compatible locking devices and egress sensors.

Installation Notes

Installation should be performed by a licensed low-voltage contractor or access control technician familiar with NFPA egress requirements and local Authority Having Jurisdiction (AHJ) approvals. Disconnect and lock out all power to the door control system before servicing or wiring the controller. Verify that the complete delayed egress assembly, including locking device, signage, and alarm, meets the requirements of NFPA 101 and any applicable local amendments before commissioning. Do not substitute components in a listed delayed egress assembly without confirming continued code compliance.
