Von Duprin 9947EO 3 US26D – Frequently Asked Questions

1) What door thickness does the Von Duprin 9947-3ft fit?
It covers 1-3/4 to 2-1/4 inch doors, and the fasteners in the box are sized for both 1-3/4 and 2-1/4 inch leaves, so a thicker hollow metal door does not need a separate fastener kit. Standard commercial hollow metal at 1-3/4 inches is the common case; the 2-1/4 inch end is what lets it go onto heavier institutional doors. Projection off the face is 3-13/16 inches, which is the number to check against a corridor clear width or anything that swings past the push pad.
2) Do I need to specify handing for a Von Duprin 9947 exit device?
In its standard build the 9947 is non-handed, so the same device goes on either leaf. Handing only becomes a real requirement when SD special center case dogging or the SS signal switch is ordered, since those put handed parts in the center case. The order form still asks for RHR or LHR, and outside orientation is what determines it.
3) Will a 3 ft concealed vertical rod device cover my 36 inch door leaf?
Yes, the 9947-3ft is sized for a 36 inch leaf. Concealed vertical rod means the rods run inside the door and the device latches at the head and the threshold rather than into the frame edge, so it secures a pair of doors without a center mullion. Device size is per leaf, so a pair of 36 inch doors takes two of them.
4) Will the 9947 latch into the strikes already in my frame and floor?
The latch throw is 3/4 inch top and bottom, so the existing top strike pocket and floor or threshold strike have to accept that much bolt at the head and sill. Von Duprin publishes the 330 top strike and 305A bottom strike as the matching hardware for the 9847/9947 concealed vertical rod. If what is in the opening now is a surface rod device, the strike locations are not the same prep and the frame head will need reworking.
5) How do I order the 9947 with a lever on the outside instead of exit only?
Trim function is a separate selection from the device. Exit only (EO) gives you a pushbar with no outside operation. For outside access, pick a lever function such as L, L-NL night latch, L-BE blank escutcheon, L-DT dummy trim or L-KC key capture, or a knob function K, K-NL, K-BE, K-DT. There are also thumbturn (TL, TL-BE), thumbpiece (TP, TP-BE), night latch (NL, NL-OP) and dummy trim (DT) options. When you choose an L function you also pick the lever design: 01, 02, 03, 05, 06 (default), 07, 17 or 18. The 990 pull trim and 996 lever or knob trim are the trim families used in Classroom, Storeroom, Dummy, Passage and Exit Only functions.
6) The Von Duprin 9947 is not wood door compatible. What concealed vertical rod device works on a wood door?
The 9947 is listed as not wood door compatible, so a wood door opening needs a device prepped for it. The BEST Precision 2701 Series is a wide stile reversible concealed vertical rod exit device for wood doors, which is the direct swap when the stile width matches what the 9947 would have taken. Verify the door core and any required reinforcement with the door manufacturer before specifying.
7) The Von Duprin 9947 is not fire rated. What concealed vertical rod device should be used on a fire rated opening instead?
The 9947 carries a Fire Rating of No, so a labeled opening needs a device built for it. The Adams Rite 3600 Series is a fire-rated concealed vertical rod exit device for hollow metal doors, and the Adams Rite 3900 Series is a fire-rated concealed vertical rod device with a 1-1/2 hour rating; both are Grade 1 and wide stile, matching the 9947 stile type. On the Sargent side, the 12-MD8613 is a fire-rated Grade 1 wide stile concealed vertical rod device in Classroom function. Fire-rated exit devices do not include dogging, so the hex key dogging hold-open on the 9947 will not carry over to the fire-rated substitute.
8) Will a Von Duprin 9947 fit a narrow stile aluminum storefront door?
No. The 9947 is a wide stile device with a center case measuring 8 inches by 2-3/4 inches by 2-3/8 inches and a 3-13/16 inch projection, which needs the stile width of a hollow metal or wide stile door. For a narrow stile aluminum opening, the Adams Rite 8600 Series is a narrow stile concealed vertical rod exit device built for aluminum doors, and the DORMA 9600BB is a Grade 1 narrow stile concealed vertical rod pushpad device in a 36 inch size. Falcon offers narrow stile concealed vertical rod devices as well, including the 1690EO at 3 ft and the 24-C Series at 36 inches, both Grade 1 exit only.
9) What is the closest wide stile concealed vertical rod equivalent to the Von Duprin 9947 from another manufacturer?
The Von Duprin 9947 is a wide stile concealed vertical rod push pad device certified to ANSI/BHMA Grade 1, non-fire-rated, for doors 1-3/4 inch to 2-1/4 inch thick. The DORMA 9100 Series matches that profile closely: it is a Grade 1 wide stile concealed vertical rod pushpad device, non-fire-rated, heavy duty, with the same 1-3/4 inch to 2-1/4 inch door thickness range. The Corbin Russwin ED5800 is another Grade 1 wide stile concealed vertical rod device, listed for 1-3/4 inch doors, in exit only or trim-accepting configurations. The BEST Precision 2801 is a wide stile concealed vertical rod device as well. Confirm trim function and finish separately, since those are ordered per opening.
10) Is a Sargent MD8613F a drop-in replacement for a Von Duprin 9947 on a 36 inch metal door?
Not a drop-in. The Sargent MD8613F-LTRIM is a Grade 1 heavy duty concealed vertical rod exit device for metal doors 36 inches by 84 inches with hex dogging, which matches the 9947 on grade, on the 36 inch door size, and on hex key dogging. What does not carry over is the door prep: concealed vertical rod devices use manufacturer-specific rod pockets, top and bottom latch cutouts, and strike locations, so a Von Duprin prepped door will not accept a Sargent device without rework. Treat it as an equivalent spec for a new or reprepped opening, not as a swap into an existing 9947 prep.
11) What dogging options can I order on the Von Duprin 9947?
Hex key dogging is standard, which holds the pushbar depressed and the latches retracted for scheduled open hours. Beyond that you can order CD cylinder dogging, CDSI cylinder dogging with security indicator, HDSI hex dogging with security indicator, DI dogging indicator, CI cylinder dogging indicator, SD special center case dogging, or LD less dogging. The indicator variants show at a glance whether the door is dogged, which is what facilities with a scheduled lockdown routine usually want. SD forces a handed device.
12) What electric options are available on the Von Duprin 9947 for access control?
For latch retraction you can order EL electric latch retraction, QEL quiet electric latch retraction, or PN pneumatic, which lets a card reader or an automatic operator pull the latches back and leave the door free to push. For monitoring, RX request to exit, LX latchbolt monitor, LX-RX combined, RX-2 double RX, RX-LC low current, WP-RX waterproof, or SS signal switch. Alarm kits are ALK, RX-ALK and LXRX-ALK. CX CHEXIT delayed egress is also a compatible upgrade: the device holds the door 15 seconds after a request to exit while a nuisance alarm sounds, which meets NFPA and IBC delayed egress requirements. Ordering SS makes the device handed.
13) Is the Von Duprin 9947 ANSI Grade 1?
Yes, certified to ANSI/BHMA A156.3 2014 Grade 1, the top grade for exit devices, plus ANSI/UL 305 and CAN/ULC-S132 panic hardware listings. Grade 1 is the cycle and strength tier institutional specs normally call for on high traffic egress, so it will satisfy a school, hospital or municipal spec written to that level. It is not fire rated, so it is for non-labeled openings.
14) What is the difference between the Von Duprin 98 and 99 Series exit devices?
They are the same 98/99 Series platform; the difference is the mechanism case. The 99 Series, which is what the 9947 is, uses a grooved case, and the 98 Series uses a smooth case. It is an appearance choice, so the usual reason to pick one is matching the cases already installed on the rest of the building's openings.
15) Should I use a concealed vertical rod device or a surface mounted one?
Concealed vertical rod puts the rods inside the door leaf, so nothing is exposed on the face and the door stays clean looking, and it latches top and bottom to hold a pair without a mullion. The trade-off is the door has to be prepped for it: concealed rods mean a factory-prepped leaf, so it is a specify-at-order-time decision, not something you retrofit onto a blank door. Surface vertical rod is what you use when the existing leaf has no concealed prep. The 9947 is the concealed type, for hollow metal, not wood.
16) Can I add request to exit or an alarm to a Von Duprin 9947 already installed?
The 98/99 Series is supported by retrofit kits, including CDSI and HDSI security dogging indicators, QEL electronic latch retraction, RX request to exit and LX latchbolt monitoring switches, AX accessible device, CX CHEXIT delayed egress, and the XP patented two-piece latchbolt. That is the practical reason facilities standardize on the 98/99 platform: the openings can pick up monitoring or electrification later without replacing the device.
17) If the opening only needs free egress with no outside trim, is there a simpler alternative to a Von Duprin 9947 with lever trim?
Yes. The 9947 is ordered with a trim function that ranges from EO exit only through knob, lever, night latch, thumbturn and thumbpiece configurations, so the exit only build already drops the outside trim. If the goal is a device that is exit only by design, the BEST Precision 2601 Series is a non-handed narrow stile concealed vertical rod device in exit only configuration, the CRL Jackson 1085 Series is a non-handed exit only wide stile concealed vertical rod panic device in a 48 inch size, and the Falcon 1690EO is a Grade 1 narrow stile exit only device at 3 ft. Stile type differs across those, so match the device to the door leaf.
18) What is the difference between a Von Duprin 9947 and a Corbin Russwin ED7800?
Both are Grade 1 concealed vertical rod exit devices, but they are built for different doors and different operation. The 9947 is a wide stile push pad device with an 8 inch by 2-3/4 inch by 2-3/8 inch center case for doors 1-3/4 inch to 2-1/4 inch thick. The Corbin Russwin ED7800 is a narrow stile crossbar device listed for 1-3/4 inch doors, in exit only or accepting operator trim. Crossbar actuation and narrow stile mounting make it a different opening entirely; the wide stile Corbin Russwin ED5800 is the closer cross-reference to the 9947.
19) Can a Falcon 1491DT be used in place of a Von Duprin 9947?
Only on the inactive leaf. The Falcon 1491DT is a dummy function narrow stile concealed vertical rod device supplied with a 9970 pull at 42 inches, so it does not latch or provide egress hardware. The 9947 is a working Grade 1 panic device with a 3/4 inch latch throw, though it can be ordered in DT dummy trim and L-DT or K-DT configurations when the outside trim is meant to be inoperable. If the requirement is a non-functioning device that matches an adjacent panic device, confirm the stile type first, since the Falcon unit is narrow stile and the 9947 is wide stile.
20) Which concealed vertical rod exit device covers a range of stile widths on a mixed door fleet?
The CRL Jackson 1285 push pad concealed vertical rod panic exit is listed for narrow, medium or wide stile in exit only function, which makes it a single part number across doors of differing stile width. The Von Duprin 9947 is a wide stile device only, so a fleet of mixed stile widths would take more than one Von Duprin model. Where the doors are consistently wide stile and the facility wants one standard, the 9947 covers exit only through lever, knob, night latch and thumbturn functions from the same series.
21) For a non-fire-rated hollow metal opening, what is the alternative to a Von Duprin 9947 that keeps the Grade 1 wide stile spec?
The Adams Rite 8500 Series is a Grade 1 wide stile concealed vertical rod exit device for hollow metal doors, listed non-fire-rated, which matches the 9947 on grade, stile type and fire rating status. The DORMA 9100 Series is a second option at Grade 1 wide stile, non-fire-rated and heavy duty, with a 1-3/4 inch to 2-1/4 inch door thickness range that mirrors the 9947. Where the specification calls out Von Duprin 98/99 Series by name, the 9947 remains the device that satisfies it directly.
22) Is a Falcon 1990EO the same as a Von Duprin 9947 for a 44 inch door?
They are not interchangeable. The Falcon 1990EO is a Grade 1 narrow stile concealed vertical rod exit device in exit only function for 1-3/4 inch doors at 44 inches, while the 9947 is a wide stile device sized for 36 inch doors and accepts thicknesses from 1-3/4 inch to 2-1/4 inch. Door width and stile type both differ, so match the device to the actual leaf width rather than treating the two as the same part in different sizes.
23) What finishes does the Von Duprin 9947 concealed vertical rod device come in?
Twelve: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 630 satin stainless steel, 643E aged bronze, 710 dark bronze anodized and 711 flat black. For matching existing openings across a building, 630 satin stainless and 626 satin chrome are the two that most commercial door hardware is already specified in.
24) Can I get the 9947 pushbar with braille or a glow strip for accessibility?
Yes. Bar options are standard bar, BR braille pushbar, SG safety glow pushbar, KN knurled bar (the tactile warning texture used on doors leading to hazardous areas), and RSS emergency exit push bar. Separately, the AX accessible device option can be ordered on the same configuration.
25) Can I quiet down a Von Duprin exit device that bangs every time someone pushes it?
Yes, two options address noise on the 9947. QM Quiet Mechanical uses the fluid damper that decelerates the push pad instead of letting it snap back, and QEL quiet electric latch retraction replaces the loud solenoid pull of standard EL. Both are ordered on the device, so it is a decision at order time rather than a field kit. This is worth specifying on hospital corridors and anywhere near occupied rooms.
