Alarm Controls Corporation DUC-3C Magnetic Lock 600 Lb

Product Description

The Alarm Controls Corporation DUC-3C is a 600-pound holding-force electromagnetic door lock finished in polished chrome. It is designed for access control applications where a reliable, fail-safe locking solution is required on interior or exterior door frames. When energized, the magnet bonds to its armature plate to hold the door securely closed. When power is removed, the door releases immediately, making this unit well suited for egress-compliant installs. Access control technicians and security contractors are the primary installers of this product.

The DUC-3C is used in commercial and light institutional settings where magnetic locking hardware is specified. Typical applications include office entry doors, server room access points, and interior security doors where an electromagnetic lock is preferred over mechanical hardware. The polished chrome finish suits environments where aesthetics are a consideration alongside function. This lock is sold as a single unit and is intended for door access control systems managed by a compatible controller or access panel.

Key Features

• 600-pound holding force for secure door retention when energized

Installation Notes

Installation is typically performed by a licensed access control or low-voltage security technician. Disconnect and lock out all power to the access control system before mounting or wiring the lock. Proper door and frame alignment is critical to achieving full rated holding force between the magnet and armature plate. Wiring should comply with applicable local electrical codes and the NEC for low-voltage control circuits.
