Product Description
Von Duprin 6223 Electric Strike — Satin Brass
The Von Duprin 6223 directly replaces the older Von Duprin 3091 and 3092 strikes. Same prep, same holes — no frame modification. Upgraded stainless steel body with modern electronics. Factory configured as fail safe with dual signal low-current monitoring switch. 24VDC operation. Fire rated UL 10C. If you've got VD 3091s or 3092s in the building, this is the factory-blessed replacement.
⚡ Fail Safe vs. Fail Secure — What's the Difference?
Fail Safe — Strike unlocks when power is lost. The door can be opened freely during a power outage. Required on most fire-rated egress doors for life safety. This is the default for fire exits and emergency egress paths.
Fail Secure — Strike remains locked when power is lost. Key override is always available from outside. Used for server rooms, evidence rooms, or anywhere security must be maintained during a power failure. The mechanical push bar still allows free egress from inside.
Pro-Tip from Our Locksmiths: If you're pulling out old VD 3091s or 3092s, the 6223 drops right in. Same prep, same screw holes. Saves a lot of time on retrofit jobs. This is a 24VDC model — make sure your power supply matches. Von Duprin PS914 or PS904 are the go-to supplies for 24V strike installations.
