Von Duprin 6400-630-12/24VDC-FSE – Frequently Asked Questions

1) Will the Von Duprin 6400 electric strike work with my existing mortise lock, or do I need a cylindrical lock?
Either. The 6400 is built to fit cylindrical locks and nearly any mortise lock, including mortise locks with offset latches. It takes a 3/4 inch latch throw and will accept a deadbolt up to 1 inch when the lock is used in a night latch function. The strike ships with two 4-7/8 inch faceplates, one for offset locks and one for centerline locks, so you cover both lock geometries out of the box.
2) Can I use a 6400 electric strike on a 3-hour fire-rated door?
Yes, on a fire-rated opening up to 3 hours. The 6400 is listed to UL 10C as a 3-hour fire-rated strike, but only in the fail-secure configuration, which is how this 32D unit is built. Fail-secure is what a fire-rated opening requires anyway: the latch stays held when power drops, so the door remains positively latched. It also carries ANSI/BHMA A156.31 Grade 1 along with UL 1034, UL 294 and CSFM listings, which is the paperwork most institutional and healthcare specs ask for.
3) My door and frame are out of alignment. Will an electric strike still latch, or do I need to rework the frame?
Misalignment is the problem the 6400 was built around. The strike has a 3-1/8 inch vertical opening, and the deadbolt keeper, plug and dead latch ramp can be inserted and locked anywhere within that opening to match where the latchbolt actually lands. Add 1/8 inch of horizontal adjustment plus the full range of vertical adjustment and you can usually chase a sagging door or a racked frame without touching the frame prep. Backbox depth is 1-3/4 inches.
4) What voltage does the Von Duprin 6400 strike run on, and how much current do I need to budget at the power supply?
Field-selectable 12 or 24 VDC, and it will also run 12/24 VAC. Continuous duty draw is 0.375 A at 12 VDC and 0.19 A at 24 VDC; on AC it is intermittent duty at 0.28 to 0.565 A. Run 24 VDC if you are sizing a supply for several openings, since the per-strike draw is roughly half. If your access control head end puts out AC and you want DC operation, a 12 VAC to 12 VDC or 24 VAC to 24 VDC rectifier is available as an option.
5) Is a fail-secure strike the right choice for my opening, or should I be looking at fail-safe?
Fail-secure means the strike keeps the latch held when power is lost, so the door stays locked from the outside and free egress still comes from turning the inside lever. That is the correct choice on a fire-rated opening and on most perimeter and tenant doors. If your opening genuinely requires the door to unlock on power loss, the 6400 is not the part; look at a field-reversible unit such as the Hager 2930, which is fire rated and switches between fail safe and fail secure in the field, or the Hager 2945 for a rim exit device application.
6) Can this electric strike go in an aluminum storefront jamb, or is it only for hollow metal?
Hollow metal, aluminum and wood frames are all listed applications for the 6400. Be honest about the jamb depth though: this strike needs a 1-3/4 inch backbox depth behind a 4-7/8 inch faceplate, which is more cavity than a shallow narrow-stile aluminum jamb usually gives you. On a tight aluminum storefront jamb, the Adams Rite 7100 or 7160 Series strikes are purpose-built for aluminum jambs with the same 1-1/4 x 4-7/8 inch faceplate, and the Adams Rite 7170 covers hollow metal and wood. Note those Adams Rite units are not fire rated, so they are out on a rated opening.
7) Will the 6400 work on a pair of doors or a double door opening?
No. The 6400 is a single door application. On a pair, the inactive leaf has no jamb for a strike to mount in, so you need a strike built for that condition, such as the Rockwood double door electric strike with a 3/4 keeper, which is Grade 1 and fire rated. If the pair is secured by surface vertical rod exit devices instead, the HES Folger Adam 310-4-2 is a complete strike pac made for surface vertical rods, though that one is not fire rated.
8) My opening has a 5/8 inch latchbolt, not the 3/4 inch the Von Duprin 6400 is set up for. What strike fits?
The Von Duprin 6400 accommodates a 3/4 inch latch throw. For a 5/8 inch latchbolt on a fire-rated opening, the SDC 45F Series is a fire-rated strike for a 5/8 inch latchbolt with a radius corner faceplate, the Adams Rite 7240 is fire-rated for cylindrical locksets with a 5/8 inch latchbolt projection, and the Hager 2925 has a 5/8 inch latch with field reversible fail safe/secure operation. The Trine 2001 covers up to a 5/8 inch throw at 16-24VAC/DC with a 5-7/8 by 1-1/4 inch faceplate. The HES Folger Adam 310-1(X) strike body takes 1/2 inch, 5/8 inch, or 3/4 inch throw latchbolts if you want one body that spans both.
9) What is the closest equivalent to the Von Duprin 6400 electric strike for a fire-rated opening with a mortise or cylindrical lock?
The Von Duprin 6400 is a Grade 1 fail-secure electric strike with a 3-hour UL 10C fire rating, a 4-7/8 inch faceplate, and a 3/4 inch latch throw, and it fits mortise or cylindrical locks on hollow metal, aluminum, or wood frames. The nearest equivalent in the same duty class is the Hager 2930, a fire-rated Grade 1 electric strike for cylindrical and mortise locks with 12/24VDC dual voltage, matching the 6400's 12/24 VDC power. The Securitron MUNL is another fire-rated Grade 1 option, though it is a mortise unlatch strike rather than a strike that covers both lock types. The Camden CX-ED1410 and CX-ED1420 are fire-rated Grade 1 universal strikes as well.
10) What is the difference between the Von Duprin 6400 and an Adams Rite 7100 or 7160 electric strike?
The Von Duprin 6400 is a Grade 1 heavy duty fail-secure strike carrying a 3-hour UL 10C fire rating and fitting mortise or cylindrical locks in hollow metal, aluminum, or wood frames. The Adams Rite 7100 and 7160 are electric strikes built for aluminum jambs with a 1-1/4 by 4-7/8 inch flat faceplate, and neither carries a fire rating. For hollow metal and wood jambs Adams Rite offers the 7170 with the same 1-1/4 by 4-7/8 inch faceplate, also without a fire rating. If the opening is fire-rated, the Adams Rite 7240 is a fire-rated strike for cylindrical locksets with a 5/8 inch latchbolt projection, which is a narrower latch than the 3/4 inch throw the 6400 accommodates.
11) Can I standardize a facility on the Von Duprin 6400, or will some openings need a different strike?
The Von Duprin 6400 covers a wide share of a facility's openings: it is non-handed, fits mortise or cylindrical locks, mounts in hollow metal, aluminum, or wood frames, and carries a Grade 1 rating with a 3-hour UL 10C fire rating for fail-secure use. Openings it does not cover are the ones with a different device type. Rim exit devices call for a rim mount strike such as the SDC 30-4 with a 3/4 inch Pullman latchbolt or the fire-rated Hager 2945 rim exit strike. Surface vertical rod openings call for the HES Folger Adam 310-4-2 strike pac. Exterior gates call for an outdoor rated strike such as the Camden CX-ED1959. Pairs of doors call for a double door strike such as the Rockwood unit with a 3/4 keeper.
12) I need a fire-rated Grade 1 electric strike but the frame prep is already cut. What are my options besides the Von Duprin 6400?
The Von Duprin 6400 uses a 4-7/8 inch faceplate and adjusts to misaligned doors and frames through a 3-1/8 inch vertical opening with 1/8 inch horizontal adjustment. Where existing prep needs a different plate, the Camden CX-ED1689L-4 is a fire-rated universal low profile strike supplied with 4 faceplates, and the Camden CX-ED1799L-8 is a fire-rated dual monitor Grade 1 strike supplied with 8 faceplates. The Locknetics NC450 is a no-cut electric strike. The HES Folger Adam 310-1(X) is a Grade 1 fire-rated strike body that accepts 1/2 inch, 5/8 inch, or 3/4 inch throw latchbolts, covering the same 3/4 inch throw the 6400 accommodates.
13) Does the 6400 electric strike need to be ordered left hand or right hand?
No handing to specify. The 6400 uses a non-handed internal solenoid, so one part number covers left and right hand openings. That is worth knowing if you are standardizing across a building: you stock one strike instead of two, and a field swap never gets held up because the wrong hand showed up.
14) What else could I buy instead of the Von Duprin 6400 for a fire-rated Grade 1 opening?
Closest equivalents in a Grade 1 fire-rated strike are the Camden CX-ED1410/CX-ED1420 universal ANSI fire-rated strikes, the Securitron MUNL mortise unlatch strike, and the HES 1500 and 1600 Series, all of which we hold as Grade 1 and fire rated. The Camden CX-ED1689L-4 is a fire-rated low profile universal that ships with four faceplates if your frame condition is uncertain. Where the 6400 separates itself is the adjustment range, a 3-1/8 inch vertical opening with the keeper positionable anywhere in it, plus 1,500 lbs. static holding force.
15) Which electric strikes besides the Von Duprin 6400 provide latchbolt monitoring for an access control system?
The Von Duprin 6400 is a fail-secure Grade 1 strike and accepts a plug-in latchbolt monitor as an optional component. If monitoring needs to be part of the strike itself, the Dortronics 3300 Series includes a latch bolt sensing switch, runs 12/24VDC to match the 6400's 12/24 VDC power, and uses a strike plate for ANSI prep at 4-7/8 by 1-1/4 inches, the same 4-7/8 inch faceplate height as the 6400. The Hager 2945 is a fire-rated rim exit strike with a latchbolt monitor and field selectable fail safe or fail secure operation, and the Camden CX-ED1799L-8 is a fire-rated dual monitor Grade 1 strike.
16) What other Grade 1 heavy duty electric strikes are available in a 32D satin stainless finish like the Von Duprin 6400?
The Von Duprin 6400 ships in a 630 satin stainless steel finish and is a Grade 1 heavy duty strike. In the same heavy duty class, the Locknetics MDS100 and MS100 are both heavy duty electric strikes in a US32D finish, and the Locknetics CS450 is offered in 32D as well. The Alarm Controls AES-100 is a Grade 1 heavy duty electric strike. Among these, the 6400 is the one that carries a 3-hour UL 10C fire rating for fail-secure operation, which is the deciding factor on a fire-rated opening.
17) What runs on AC power instead of the Von Duprin 6400's DC supply?
The Von Duprin 6400 is field-selectable for 12/24 VDC, with 12/24 VAC available on intermittent duty. If the panel supplies AC, the Trine 004 is a fire-rated fail-secure strike running 8-16VAC with a 6-1/4 by 1-3/8 inch faceplate and up to a 5/8 inch throw, and the Trine 2001 runs 16-24VAC/DC, fire-rated fail secure, with a 5-7/8 by 1-1/4 inch faceplate. Both use a larger faceplate than the 6400's 4-7/8 inch plate, so confirm the frame prep before ordering.
18) What finish does the Von Duprin 6400 32D come in, and will it match my other door hardware?
One finish: 630 satin stainless steel, which is the same thing as US32D. That is the default commercial finish on levers, exit devices and hinges in most office, healthcare and school buildings, so it drops into an existing 630 opening without looking wrong. If your building is standardized on 626 satin chrome, the strike will read slightly brighter than the trim next to it.
19) Can the 6400 electric strike be used on an exterior door or a gate?
Exterior doors, yes. The heavy-duty stainless steel body in a 630 satin stainless finish gives corrosion resistance for interior or exterior openings in hollow metal, aluminum or wood frames. A gate is a different problem: for an outdoor gate application, the Camden CX-ED1959 Series is the outdoor rated gate strike we carry, though it is not fire rated.
