Sdc 45-4SU Heavy Duty Electric Strike 12/24 Vdc

Product Description

The SDC - SECURITY DOOR CONTROLS 45-4SU is a heavy duty electric strike designed for access control applications in commercial and industrial door assemblies. Operating on 12 or 24 volts DC, this strike replaces a standard door frame keeper and allows remote release of a locked door without retracting a latchbolt. It is sized at approximately 4 7/8 inches in length, making it compatible with standard commercial hollow metal and wood frame cutouts. Access control technicians and licensed electricians install this type of hardware as part of broader electronic access control systems.

The 45-4SU is suited for commercial entry doors, office suites, stairwell access points, and other controlled-access openings where remote electric release is required. Its dual-voltage operation simplifies integration into both 12 VDC and 24 VDC access control panels, reducing the need for additional power supply matching at install. The heavy duty construction targets high-traffic commercial environments where standard-duty strikes would experience accelerated wear.

Key Features

• Dual-voltage operation accepts 12 VDC or 24 VDC input for flexible panel integration
• Heavy duty construction rated for high-traffic commercial applications
• 4 7/8 inch body length fits standard commercial door frame cutouts
• Electric strike format allows door release without retracting the latchbolt
• Single-unit packaging for straightforward replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation electric strike for commercial door frames requiring a heavy duty 12/24 VDC electric strike in a 4 7/8 inch form factor.

Installation Notes

Installation of electric strikes should be performed by a licensed access control technician or electrician familiar with low-voltage door hardware and applicable local codes. Disconnect power to the access control panel and any door position switch circuits before beginning work. Verify frame type and cutout dimensions before installing to confirm proper fitment. Follow the manufacturer product manual for wiring polarity, fail-safe versus fail-secure configuration, and strike alignment procedures.
