Sdc 1581VD Electromagnetic Lock 650 Lb 12/24VDC Dps

Product Description

The SDC - SECURITY DOOR CONTROLS 1581VD is a heavy-duty electromagnetic door lock designed for access control applications in commercial and institutional buildings. Operating on 12 or 24 volts DC, this mag lock delivers a 650-pound holding force, providing a high level of physical security at controlled entry points. It includes an integrated Door Position Sensor (DPS), which allows the access control system to monitor whether the door is open or closed in real time. The 1581VD is typically installed by licensed security technicians or low-voltage contractors as part of a broader electronic access control system.

The 1581VD is suited for single-door access control installations in commercial buildings, office facilities, schools, healthcare environments, and government buildings. It mounts to the door frame and door face, typically on aluminum or hollow metal door assemblies. The integrated DPS function eliminates the need for a separate door position switch, reducing hardware count and simplifying wiring at the door junction. This model is appropriate for interior and covered-entry doors where a fail-safe locking solution is required.

Key Features

• 650-pound static holding force for high-security door control
• Dual-voltage operation at 12 or 24 volts DC for flexible power supply integration
• Integrated Door Position Sensor (DPS) provides real-time door status monitoring
• Fail-safe design releases the lock when power is cut, supporting life-safety egress requirements
• Compact electromagnetic design with no moving mechanical parts for long service life

Compatibility

Designed as an OEM-style electromagnetic lock for use in commercial access control systems requiring a 12/24 VDC fail-safe mag lock with integrated door position sensing.

Installation Notes

Installation should be performed by a licensed low-voltage technician or access control installer familiar with NFPA 101 life-safety egress requirements and local building codes. Disconnect power to the access control panel before wiring the lock. Verify supply voltage matches the selected operating voltage before applying power. Do not install on fire-rated door assemblies unless the lock and hardware configuration has been reviewed for code compliance with the authority having jurisdiction.
