Product Description

The DORMAKABA USA INC. RCI 831040 is a single-magnet electromagnetic lock rated for both 12-volt and 24-volt operation. Mag locks of this type use direct-current electromagnets to hold a door securely in the closed position, releasing instantly when power is interrupted. The 831040 is designed for access control applications where fail-safe egress is required by code. Licensed locksmiths, low-voltage electricians, and access control technicians are the primary installers of this hardware.

This electromagnetic lock is suited for single-door access control installations in commercial and light industrial settings. Typical applications include interior and perimeter doors in office buildings, server rooms, warehouses, and other facilities where controlled entry is required. The dual-voltage 12 volt and 24 volt compatibility allows integration with a wide range of access control panels and power supplies already in the field.

Installation Notes

Installation of electromagnetic locks is typically performed by a licensed low-voltage electrician or certified access control technician. Disconnect and lock out all power to the access control panel and door hardware before beginning installation. Mounting must comply with applicable local building codes and fire egress requirements, including NFPA 101 where applicable. Verify supply voltage matches the lock's operating range before energizing.
