Von Duprin 51003FP28 Fail Secure Electric Strike 24V

Product Description

The VON DUPRIN 51003FP28 is a 24 volt DC fail secure electric strike designed for use in commercial access control applications. In a fail secure configuration, the strike remains locked when power is removed, making it appropriate for doors where a locked state during a power outage is required by security protocol. The unit ships with three interchangeable faceplates to accommodate different door frame preparations. At 1.7 pounds, it is a compact strike suitable for hollow metal and aluminum frame installations. Licensed access control technicians and commercial locksmiths are the primary installers.

This electric strike is intended for commercial and institutional door hardware applications where electronic access control is integrated with a locking system. Typical installations include office entry doors, stairwell doors, and controlled-access corridors in commercial buildings. The three included faceplates allow the installer to match the strike to various mortise cutout dimensions without sourcing additional hardware. The 689 aluminum finish is a standard anodized finish commonly specified in commercial construction documents.

Installation Notes

Electric strike installation should be performed by a licensed locksmith or access control technician in accordance with applicable local codes and the door manufacturer's frame preparation requirements. Disconnect and lock out all power to the access control system before beginning installation or wiring work. Verify that the power supply output matches the 24 volt DC requirement of this strike before connecting. Do not force the strike housing into an undersized frame cutout — confirm the correct faceplate is selected before final mounting.
