Dormakaba Rci S2500A-12 Electromagnetic Door Lock 12VDC

Product Description

The DORMAKABA RCI S2500A-12 is a 12-volt DC electromagnetic door lock designed for access control applications. Commonly called a mag lock, this device holds a door securely in the closed position by generating a strong magnetic field between the magnet body and a steel armature plate. When power is removed, the door releases immediately, making it well-suited for fail-safe egress requirements. Licensed access control installers and low-voltage technicians are the primary trade professionals who specify and install this hardware.

The S2500A-12 is intended for use in commercial and light-industrial door applications where electric locking hardware is required. Typical installations include single swinging doors in office buildings, data centers, schools, and government facilities where access control panels, keypads, or card readers govern entry. The unit operates on a 12-volt DC supply, which aligns with standard access control power supplies commonly found in these environments.

Key Features

• 12-volt DC operation compatible with standard access control power supplies
• Fail-safe design releases the door immediately upon power loss
• Electromagnetic holding force suitable for commercial door applications
• Sold as a single unit for straightforward procurement and installation

Compatibility

Designed as an OEM-style electromagnetic mag lock for commercial access control door installations requiring a 12-volt DC fail-safe locking device.

Installation Notes

Installation should be performed by a licensed low-voltage or access control technician in accordance with applicable local codes and NFPA 70 (NEC) requirements. Disconnect and lock out all power to the access control system before mounting or wiring the device. Verify that the door frame and armature plate mounting surface are properly aligned to ensure full magnetic contact. Consult the manufacturer data sheet for wiring diagrams and mounting hardware specifications before beginning the installation.
