Von Duprin VON-6221-FS-24-630 – Frequently Asked Questions

1) Will the Von Duprin 6221 electric strike work with my existing cylindrical lockset, or do I need a mortise lock?
Either one. The 6221 is built for mortise or cylindrical locksets, and it accepts latchbolts with a 3/4 inch throw. The one exclusion worth catching before you order: on the mortise side it works with mortise locks without a deadbolt. If the lock on that opening throws a deadbolt as well as a latch, this is not the strike for it.
2) Is the Von Duprin 6221 fire rated for a labeled opening?
Yes. The 6221 is UL 10C fire rated to 3 hours on single doors and 90 minutes on pair doors with an inactive leaf. It's also UL 1034 listed for burglary-resistant electric strikes, UL 294 listed, and certified ANSI/BHMA A156.31 Grade 1. That combination is what an inspector wants to see on a labeled fire door in a school, hospital, or government building.
3) Can the Von Duprin 6221 be set up fail-safe instead of fail-secure?
Both are available. The 6221 ships standard in fail-secure, meaning the door stays locked when power drops and the strike releases only when energized. Fail-safe versions are also orderable, releasing the keeper on power loss so the opening free-egresses in an alarm condition. Pick fail-safe where the fire alarm or life-safety system has to unlock the door, fail-secure where losing power must not open it. Both configurations are available in 12 VDC and 24 VDC.
4) What voltage do I need to run a Von Duprin 6221 electric strike?
24 VDC is the standard, and 12 VDC is the other orderable option, so match it to the power supply already feeding the opening. The strike is also field-selectable across 12, 16, 24, and 28 VDC, drawing 0.6A at 12V, 0.4A at 16V, 0.33A at 24V, and 0.25A at 28V continuous duty. If your supply is AC, rectifier kits are offered for 12 VAC to 12 VDC and 24 VAC to 24 VDC.
5) Will the Von Duprin 6221 retrofit an older Von Duprin 3071 or 3072 strike?
It will. The 6221 is a stated retrofit for the Von Duprin 3071 and 3072, so you can pull the old strike and drop this one into the same opening rather than reworking the frame. Von Duprin also lists it as retrofitting competitive and older-model Von Duprin electric strikes generally. It's non-handed, so there's no left or right version to specify.
6) Will the Von Duprin 6221 work behind a rim exit device?
No. The 6221 is a strike for mortise or cylindrical locksets, not for exit device hardware. For a rim device with a Pullman latch, the SDC 30-4 Series is a 3/4 inch Pullman latchbolt rim mount strike in stainless steel, and the Hager 2945 is a fire-rated rim exit strike. Sizing a lockset strike to an exit device is one of the more common wrong orders on this category, so settle which hardware is on the door first.
7) The frame is an aluminum jamb with a narrow stile lock, not a cylindrical or mortise lockset. What electric strike should be used instead of the 6221?
The 6221 is built for mortise locks without deadbolt and cylindrical locksets in hollow metal, aluminum, or wood frames, so a narrow stile aluminum jamb with a deadlatch is a different prep. The Adams Rite 7100 Series electric strike is made for aluminum jambs and uses a flat faceplate measuring 1-1/4 inches by 4-7/8 inches, and the Adams Rite 7160 covers aluminum jambs with the same 1-1/4 inch by 4-7/8 inch faceplate. Note that both Adams Rite 7100 and 7160 are non fire rated, so they do not serve a labeled opening the way the fire rated 6221 does.
8) Is a 5/8 inch latchbolt electric strike a substitute for the Von Duprin 6221?
Not directly. The 6221 has a 3/4 inch latch throw, while several common strikes are built around a shorter projection: the Adams Rite 7240 is a fire rated cylindrical lockset strike with 5/8 inch latchbolt projection, the SDC 45F is a fire rated strike with 5/8 inch latchbolt compatibility and a radius corner faceplate, and the SDC 25 Series covers 1/2 inch latchbolt. Measure the actual latchbolt projection on the lockset before ordering, because a keeper cut for 5/8 inch will not clear a 3/4 inch throw. The HES Folger Adam 310-1(X) strike body is the exception in this group, built for 1/2 inch, 5/8 inch or 3/4 inch throw latchbolts and Grade 1 fire rated.
9) Which electric strike gives latch monitoring or door status output, since the 6221 does not?
The 6221 is a Grade 1 fire rated strike for mortise and cylindrical locks and is specified on power, throw, and rating rather than on monitoring. If the access control system needs a latch or monitor contact, the Dortronics 3300 Series is an electric strike with a latch bolt sensing switch running 12/24VDC with a strike plate for ANSI prep at 4-7/8 inches by 1-1/4 inches, matching the 6221 on 12/24 VDC power. The Camden CX-ED1799L-8 is a fire rated dual monitor Grade 1 electric strike supplied with 8 faceplates, and the Hager 2945 fire rated rim exit strike includes a latchbolt monitor.
10) Which electric strike suits a rim exit device rather than a mortise or cylindrical lockset?
The 6221 is specified for mortise or cylindrical locks, so a rim exit device needs a rim strike instead. The SDC 30-4 Series is a rim mount electric strike for a 3/4 inch Pullman latchbolt with stainless steel construction, matching the 3/4 inch throw the 6221 also accepts. If the exit opening is fire labeled and needs latch monitoring, the Hager 2945 is a fire rated rim exit strike with field selectable fail safe/fail secure and a latchbolt monitor. For surface vertical rod exit hardware, the HES Folger Adam 310-4-2 is a complete Grade 1 electric strike pac, though it is not fire rated.
11) The existing frame prep does not match the 6221 faceplate. What universal or multi-faceplate electric strike covers an unknown cutout?
The 6221 uses a 6 inch faceplate, so a frame cut for a different strike will need filling or a different unit. 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 Grade 1 strike supplied with 8 faceplates, so one kit can adapt to several existing preps. The Camden CX-ED1410 and CX-ED1420 Series are universal Grade 1 ANSI fire-rated strikes as well. Where no cutting is possible at all, the Locknetics NC450 is a no cut electric strike.
12) How much force will the 6221 electric strike hold, and is it rated for a high-traffic door?
1,300 lbs holding force, 70 ft-lbs of dynamic strength, and endurance tested to 1,000,000 cycles. It's a heavy-duty Grade 1 strike in stainless steel with an integrated faceplate. On a main entrance, a stairwell, or a tenant door cycling all day, that cycle count is the number that matters, and it's the reason this sits above a light-commercial strike like the Trine 001 Series.
13) Can I use one 6221 strike on a pair of doors?
Yes, the 6221 is listed for double-door applications, and it holds its fire label on pairs at 90 minutes with the inactive leaf. Note what it does not do: this is a strike for a mortise or cylindrical latch, not for vertical rod hardware. If the pair runs surface vertical rods, you want a strike built for that, like the HES Folger Adam 310-4-2 pac for surface vertical rods, or the Rockwood double-door strike with a 3/4 keeper.
14) What comes with the Von Duprin 6221 for installation and later service?
Two-piece plug connectors are included, which is the detail that saves a service call later. You can unplug the strike at the jamb to pull and bench it without cutting and re-splicing wire in the frame. The faceplate is integrated into the stainless body rather than being a separate piece, and the strike is non-handed, so there's no handing to specify and no separate plate to order.
15) What's a comparable Grade 1 fire-rated electric strike if the Von Duprin 6221 isn't the right fit?
Staying Grade 1 and fire rated, the Securitron MUNL Series mortise unlatch strike and the HES Folger Adam 310-1(X) body are the closest peers, and the 310-1(X) covers 1/2, 5/8, and 3/4 inch latchbolts. The Hager 2930 is the direct functional analogue: fire rated, for cylindrical and mortise locks, 12/24 VDC dual voltage, with field-reversible fail-safe or fail-secure rather than a configuration you pick at order time. The Camden CX-ED1410 and CX-ED1420 Series are fire-rated universal Grade 1 strikes if you want one part to cover mixed prep across a building.
16) How many configurations of the Von Duprin 6200 Series strike are there, and what do I have to specify when ordering?
Three things decide the part: voltage (12 or 24 VDC), fail-safe or fail-secure, and one of six finishes, which is 24 orderable combinations on the 6221 alone. Von Duprin offers 17 model configurations across the 6200 Series for cylindrical and mortise applications. Handing you can skip, the strike is non-handed. Add a rectifier kit to the order if the door is fed from an AC supply.
17) What is a simpler electric strike option when the opening is not fire rated and does not need heavy duty performance?
The 6221 is a heavy duty Grade 1 commercial strike with fire rating and a 1300 lb holding force, which is more strike than an unlabeled interior or light commercial door calls for. The Trine 001 Series is a fail-secure light commercial electric strike with a 5-7/8 inch by 1-1/4 inch faceplate and is not fire rated, and the RCI 15BS is an economy electric strike for special offset latch entry with fail-secure operation, also non fire rated. Both are fixed fail-secure, so they do not offer the field-configurable fail-safe setting the 6221 carries, and neither belongs on a labeled opening.
18) The system supplies AC power, not DC. What electric strike works where the 6221 needs a rectifier?
The 6221 runs 12/24 VDC and uses optional rectifier kits to take AC input. Where the transformer output is AC, the Trine 2001 in the 4300CC series is a fire rated strike running 16-24VAC/DC, fail secure, with a 5-7/8 inch by 1-1/4 inch faceplate and up to 5/8 inch throw. The Trine 004 is a fire rated strike running 8-16VAC, fail secure, with a 6-1/4 inch by 1-3/8 inch faceplate and up to 5/8 inch throw. Both accept a shorter latchbolt projection than the 6221's 3/4 inch throw, so verify the lockset latch before ordering.
19) Is an electric strike accessory kit the same as ordering a complete electric strike?
No. The HES 1500 and HES 1600 items are electric strike accessories for those Grade 1 fire rated series, and the HES Folger Adam 310-1(X) is a strike body rather than a full assembly. Those are parts that support an existing strike, not a complete unit. The Von Duprin 6221 is a complete heavy duty electric strike with an integrated faceplate, sold in a 6 inch faceplate with two-piece plug connectors included. If a whole opening is being built out, order a complete assembly such as the HES Folger Adam 310-4-2 complete electric strike pac rather than an accessory line.
20) For a pair of doors with an inactive leaf, what electric strike besides the 6221 handles the double door application?
The 6221 is specified for double door application, fire rated to 3 hours on single doors and 90 minutes on pair doors with an inactive leaf. The Rockwood electric strike for double doors is a Grade 1 fire rated unit in the 310-1 Series with a 3/4 keeper, which is the same keeper size class as the 6221's 3/4 inch latch throw. Both are non-handed considerations at the frame, so confirm the inactive leaf prep and the strike cutout on the drawing before selecting between them.
21) What finishes does the Von Duprin 6221 come in, and will it match the other hardware in the building?
Six finishes, all of them available in either voltage and either fail configuration: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 629 bright stainless, and 630 satin stainless. For a property manager standardizing a floor, 630 satin stainless is the one that lines up with most commercial lever and exit hardware already in place; 613 is the match for dark bronze packages.
22) Is the Von Duprin 6221 rated for an exterior door?
It is. Interior or exterior openings are both covered, in hollow metal, aluminum, or wood frames, with stainless steel construction throughout. It's a commercial-duty part, not a residential one. If the opening is an exterior gate rather than a door, that's a different animal and the Camden CX-ED1959 Series outdoor-rated gate strikes are the ones built for it.
