Sdc 1581Y Single Electromagnetic Lock 12 24VDC

Product Description

The SDC Security Door Controls 1581Y is a single electromagnetic lock designed for access control applications in commercial and institutional door systems. Operating on either 12 or 24 volts DC, this electromagnetic lock provides a holding force of 335 pounds to secure a door in the locked position when energized. The 1581Y mounts to the door frame and works in tandem with an armature plate mounted on the door leaf. Installation is typically performed by licensed access control or low-voltage security technicians as part of an integrated access control system.

The 1581Y is suited for single door applications in commercial buildings, office environments, schools, healthcare facilities, and other locations requiring controlled entry. It is commonly installed on aluminum, wood, or hollow metal door frames where a flush or surface-mount electromagnetic lock is required. The dual-voltage compatibility at 12 or 24 VDC makes it adaptable to a wide range of access control panels and power supplies already in use on the job site.

Key Features

• Dual-voltage operation at 12 or 24 VDC for compatibility with common access control power supplies
• 335-pound holding force secures single door openings in commercial and institutional settings
• Electromagnetic locking mechanism with no moving parts, reducing mechanical wear over time
• Sold as a single unit, one lock per package

Compatibility

Designed as an OEM-style electromagnetic lock for single door access control installations requiring 12 or 24 VDC input and a 335-pound holding force.

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 de-energize the access control power supply before wiring or mounting the lock. Verify that the door frame and door leaf can accommodate the lock body and armature plate dimensions before mounting. Confirm the system power supply output matches the selected operating voltage before applying power.
