Sdc 1511Y Electromagnetic Door Lock 12/24VDC 335 Lb

Product Description

The SDC - SECURITY DOOR CONTROLS 1511Y is a single-door electromagnetic lock designed for access control applications requiring reliable, electrically operated door holding. Operating on 12 or 24 volts DC, the 1511Y delivers 335 pounds of holding force, making it suitable for standard interior and perimeter door applications in commercial and institutional settings. The lock holds the door secured when power is applied and releases instantly upon power interruption, supporting fail-safe egress requirements. Installation is typically performed by licensed electricians or low-voltage access control technicians.

The 1511Y is intended for single-door installations in commercial buildings, schools, healthcare facilities, and secured access areas where electromagnetic locking is specified. It is well-suited for integration with access control systems, push-button release stations, request-to-exit devices, and fire alarm interfaces. The dual-voltage 12/24 VDC input makes it adaptable to a variety of control panel configurations without requiring a dedicated power supply voltage.
