Sdc 1591U Electromagnetic Lock 12/24 Vdc

Product Description

The SDC - SECURITY DOOR CONTROLS 1591U is an electromagnetic door lock designed for access control applications operating at 12 or 24 volts DC. Commonly called an Emlock, this unit uses magnetic force to hold a door in the secured position when energized, releasing instantly when power is interrupted or an authorized signal is received. The 630 finish designation indicates a satin stainless appearance, suited for commercial and institutional door hardware environments. Licensed locksmiths, access control technicians, and low-voltage security installers are the primary trades that specify and install this hardware.

The 1591U is applicable to commercial and institutional access control installations where fail-safe door holding is required. Fail-safe operation means the lock releases on power loss, making it appropriate for egress-compliant door applications such as stairwells, corridors, and entry points that must remain passable during a power outage or fire alarm event. It is sold as a single unit and is suited for interior door frames where surface-mounted electromagnetic hardware is specified by the system designer or integrator.

Key Features

• Dual-voltage operation at 12 or 24 volts DC allows compatibility with a range of access control power supplies
• Fail-safe electromagnetic design releases instantly upon power interruption for code-compliant egress
• 630 satin stainless finish provides a clean, professional appearance on commercial door frames

Compatibility

Designed as an OEM-style electromagnetic lock for use in commercial access control door hardware systems requiring 12 or 24 VDC fail-safe magnetic locking.

Installation Notes

Installation is typically performed by a licensed locksmith, access control technician, or low-voltage security contractor. Disconnect and lock out all power to the access control system before mounting or wiring the lock. Surface mounting requires the door and frame to be properly aligned so the armature plate makes full contact with the magnet face. Wiring should comply with applicable local electrical codes and any relevant low-voltage installation standards.
