Sdc 1571V Electromagnetic Lock 1200 Lbs 12/24 Vdc

Product Description

The SDC - SECURITY DOOR CONTROLS 1571V is a heavy-duty electromagnetic lock rated for 1200 pounds of holding force and designed for access control applications in commercial and institutional entry systems. Operating on a dual voltage input of 12 or 24 volts DC, the 1571V provides fail-safe door security by releasing the door when power is cut. The unit is installed by licensed electricians or security system integrators as part of a complete access control installation. Its high holding force makes it suitable for high-traffic or high-security door openings where positive locking is required.

The 1571V electromagnetic lock is intended for use on single door applications in commercial buildings, government facilities, schools, and multi-tenant access points. It is typically mounted on the door frame or header and pairs with an armature plate mounted to the door leaf. Installation is common on aluminum storefront frames, hollow metal frames, and wood doors with appropriate mounting hardware. This lock category is a standard component in card reader, keypad, and intercom-based access control systems managed by security integrators.

Key Features

• 1200 pounds static holding force for high-security door applications
• Dual voltage operation at 12 or 24 volts DC for flexible power supply compatibility
• Fail-safe design releases the lock on power loss, supporting life-safety egress requirements
• Compact electromagnetic design with no moving parts reduces maintenance requirements
• Suitable for single door access control installations in commercial and institutional environments

Compatibility

Designed as an OEM-style electromagnetic lock for commercial access control systems requiring a 1200-pound holding force mag lock with 12/24 VDC input.

Installation Notes

Installation should be performed by a licensed electrician or certified security systems integrator in accordance with applicable NEC requirements for low-voltage access control wiring. Before installation or service, disconnect all power to the access control panel and verify zero voltage at the lock wiring terminals. Armature plate alignment is critical to achieving rated holding force — ensure the armature and magnet face are flush and parallel before finalizing the mount. Do not energize the lock without the armature plate in place.
