Sdc 1511X Electromagnetic Door Lock 12/24 Vdc

Product Description

The SDC - SECURITY DOOR CONTROLS 1511X is an electromagnetic door lock, commonly called an emlock, designed for access control applications on single-door installations. Operating on either 12 or 24 volts DC, the 1511X provides a fail-safe magnetic holding force to keep a door secured when energized. It is installed by licensed security, electrical, or access control technicians as part of a complete door hardware and access control system. The dual-voltage input makes it adaptable to a wide range of control panel power supplies without requiring a dedicated transformer.

The 1511X is suited for commercial and light-industrial door applications where electromagnetic locking is the preferred hardware method. It is typically mounted to the door frame or header on single-door configurations, working in conjunction with an armature plate mounted to the door leaf. The lock integrates into access control systems that supply 12 or 24 volts DC and a door position signal. It is commonly specified by security integrators, electrical contractors, and door hardware professionals on interior and exterior access points.

Key Features

• Dual-voltage operation at 12 or 24 volts DC for compatibility with common access control power supplies
• Fail-safe design — door releases automatically when power is removed, meeting life-safety egress requirements
• Single-door configuration suitable for standard commercial door openings
• Compact emlock form factor for surface-mount header or frame installation
• Door position sensor (DPS) integration supports monitoring of door status at the control panel

Compatibility

Designed as an OEM-style electromagnetic lock for single-door access control installations using 12 or 24 volt DC power supplies in commercial access control systems.

Installation Notes

Installation should be performed by a qualified access control or electrical technician in accordance with local codes and NEC requirements for low-voltage access control wiring. Disconnect and lock out all power to the access control panel before wiring or mounting the lock. The armature plate must be properly aligned to the lock face to achieve full holding force — misalignment reduces performance significantly. Confirm door position sensor wiring is routed and terminated per the control panel manufacturer's requirements before restoring power.
