Product Description
6400 US32D Von Duprin 6400 Series Modular Electric Strike, Fail Secure, 12/24 VDC, Satin Stainless (630)
The 6400 is Von Duprin's modular electric strike for mortise and cylindrical locks. Modular means one strike body with movable inserts. A deadbolt keeper, a plug and deadlatch ramp inserts set it up for the lock on the door, so one strike covers cylindrical locks and nearly any mortise lock. It mounts in hollow metal, wood or aluminum frames on single doors.
It runs on 12 or 24 VDC, chosen with the plug-in voltage connectors in the box: 375 mA at 12 VDC, 190 mA at 24 VDC. It is fail secure: the door stays locked when power drops. It is UL 10C three-hour fire rated in fail secure. A mortise lock deadbolt up to 1" throw can project into the strike, but the deadbolt has to be retracted and extended by hand. The strike only releases the latch.

Pro-Installer FAQ
Q: Can I make it fail safe?
A: Not this strike. The 6400 is a fail secure strike, and fail secure is how it carries its fire rating. If the opening needs fail safe, look at a strike Von Duprin builds with a selectable power failure mode, such as the 6100 or 6200 Series.
Q: My power supply is AC. Will it work?
A: The strike runs on 12 or 24 VDC. Von Duprin sells 12 VAC and 24 VAC rectifier kits as options for AC supplies, intended for fail secure, momentary use.
Q: Can I monitor whether the door is latched?
A: Yes, with the LM6400 latch monitor. It plugs in and can be added in the field.
