Von Duprin 6223 12V 32D Electric Strike Fail Secure 12V

Product Description

The VON DUPRIN 6223 12V 32D is a Grade 1 electric strike designed for fail-secure operation, meaning the strike remains locked when power is removed and unlocks only when voltage is applied. Rated at 12 volts DC, it features a 6-inch by 1-1/4-inch faceplate finished in satin stainless steel. This unit carries a fire rating, making it suitable for installations where code-compliant life-safety hardware is required. It is intended for installation by licensed security or access control technicians on commercial and institutional door assemblies requiring controlled entry.

This electric strike is designed for use on double doors with a closed back configuration. It is compatible with cylindrical and mortise locksets and installs into hollow metal, aluminum, or wood door frames. Typical applications include commercial office buildings, institutional facilities, schools, and healthcare environments where access control integration is required at paired door openings. The fail-secure design is commonly specified for perimeter doors and secure interior zones where the door must remain locked during a power loss event.

Installation Notes

Electric strikes of this type are typically installed by licensed locksmiths, security technicians, or electricians qualified to perform low-voltage access control work. Power to the access control system and any connected locking hardware must be fully de-energized before beginning installation or wiring. Installations on fire-rated door assemblies must comply with applicable fire and building codes, including listings for the complete door assembly. Confirm that the power supply output matches the 12 VDC requirement before energizing the circuit.
