Sdc 1511VDBT Electromagnetic Door Lock 12/24 Vdc

Product Description

The SDC - SECURITY DOOR CONTROLS 1511VDBT is an electromagnetic door lock, commonly called an emlock, designed for access control applications in commercial and institutional buildings. Operating on 12 or 24 volts DC, it provides a magnetically held locking mechanism that releases immediately when power is interrupted, supporting fail-safe door hardware configurations. The 1511VDBT is built in a mortise-style form factor suited for aluminum storefront, wood, or hollow metal door frames. Installation is typically handled by licensed access control or low-voltage security technicians working alongside a licensed electrician where local codes require.

This electromagnetic lock is intended for use in commercial door access control systems where a fail-safe, power-to-lock or power-to-hold configuration is required. The DPS designation indicates an integrated door position switch, which provides door status feedback to the access control panel or alarm system. The 628 finish designates a satin aluminum anodized surface, appropriate for aluminum storefront and contemporary commercial door hardware. Typical installation scenarios include single-door entry points, vestibule doors, stairwell access doors, and interior security perimeter doors in commercial facilities.

Installation Notes

Installation should be performed by a qualified low-voltage access control technician, with electrical connections made in accordance with NEC Article 725 for Class 2 or Class 3 low-voltage circuits. Disconnect all power to the door controller and access control panel before wiring or mounting the device. Verify door frame alignment before final mounting to ensure full contact between the magnet and armature plate for rated holding force. Do not apply power until all wiring connections are confirmed correct and secure.
