Von Duprin 9847WDC EO 4 US26D – Frequently Asked Questions

1) Do I have to specify handing on the Von Duprin 9847WDC exit device?
The device itself is non-handed, so the mechanism works either way. Handing is still a required selection at order time, RHR (right hand reverse) or LHR (left hand reverse), and it becomes a real mechanical difference when you pick the SD special dogging or SS signal switch options, which are handed. If you are stocking spares for a building, the base non-handed device is what keeps the shelf count down.
2) How does a concealed vertical rod exit device latch a pair of wood doors without a mullion?
A concealed vertical rod device latches at the head and the threshold rather than into the door edge, so a pair of doors can be secured with no center mullion in the opening. The 9847WDC runs its rods inside the wood door, which is why the door has to be prepped for it, and the top and bottom latches carry a 3/4 inch throw. If you would rather not prep the doors internally, a rim device with a removable mullion is the alternative for a pair, but it puts a vertical post in the middle of the clear opening.
3) Is there a Von Duprin exit device option that meets the 5 pound ADA operating force requirement?
Yes, the AX accessible device option. Von Duprin certifies AX to the 5 lb. force requirements of 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. AX is a selection made at order time on the 9847WDC, not a field kit, so specify it up front on any opening on an accessible route.
4) Can the Von Duprin 9847WDC be tied into an access control system?
Yes, several ways, and they are order-time selections. For monitoring, RX request-to-exit and LX latchbolt monitor are available, along with LX-RX combined, WP-RX waterproof, RX-LC low current, RX-2 double RX, and SS signal switch. For remote unlocking, EL electric latch retraction, QEL quiet electric latch retraction, and PN pneumatic retraction are the latch retraction choices. Alarm kits ALK, RX-ALK and LXRX-ALK cover local alarm on egress. RX and LX are also available as retrofit upgrades if the device is already installed.
5) What trim do I order with a Von Duprin 9847WDC and what does exit only mean?
Trim is a required choice and there are seventeen functions. EO is exit only, no outside operation at all, which is what you use on a stair discharge or a rear door nobody comes in through. If you need to get back in, NL night latch (key retracts the latch) or the lever versions L, L-NL, L-KC, L-BE, L-DT give outside access, and knob versions K, K-NL, K-BE, K-DT do the same with a knob. TL thumbturn, TP thumbpiece, DT dummy trim, and NL-OP night latch with optional pull round it out. If you pick an L lever function you also choose the lever design, 06 is default with 01, 02, 03, 05, 07, 17 and 18 also offered.
6) What is the difference between a wide stile and narrow stile concealed vertical rod exit device?
Stile width is the vertical rail at the lock edge, and it determines what will physically mount. The 9847WDC is a wide stile device, correct for wood and hollow metal doors that have a broad lock stile. Aluminum storefront doors typically have a narrow stile and need a narrow stile device instead, such as the Adams Rite 8600 Series for aluminum doors, the Corbin Russwin ED4800, or the Falcon 1690EO. Fitting a wide stile device to a narrow stile leaf is the most common ordering mistake on this category.
7) Is the Von Duprin 9847WDC Grade 1 and what does that mean for a school or hospital?
Certified to ANSI/BHMA A156.3 2014 Grade 1, the highest of the three ANSI durability grades for exit devices, and UL listed under ANSI/UL 305 and CAN/ULC-S132 for panic hardware. Grade 1 is the specification level institutional work is normally written to, so it satisfies a spec calling for Grade 1 panic hardware on a wood door. It is not fire rated, so it cannot go on a labeled opening.
8) What is the closest wide stile concealed vertical rod exit device to the Von Duprin 9847WDC for a wood door?
The BEST Precision 2701 is the nearest match on door material: it is a wide stile reversible concealed vertical rod exit device built for wood doors, the same application the 9847WDC-4ft covers with its wood door concealed vertical rod design and non-handed configuration. The Corbin Russwin ED5800 is also a Grade 1 wide stile concealed vertical rod device rated for 1-3/4 inch doors, matching the 9847WDC-4ft door thickness, though its function is exit only or accepts trim. The 9847WDC-4ft carries a 3/4 inch latch throw and an 8 inch x 2-3/4 inch x 2-3/8 inch center case.
9) The opening needs a fire rated concealed vertical rod exit device - what should be used instead of the Von Duprin 9847WDC-4ft?
The 9847WDC-4ft carries a fire rating of No, so a labeled opening needs a device certified for it. The Adams Rite 3600 Series is a fire rated Grade 1 wide stile concealed vertical rod device for hollow metal doors, and the Adams Rite 3900 Series is a fire rated Grade 1 wide stile concealed vertical rod device with a 1-1/2 hour rating. The Sargent 12-MD8613 is a fire rated Grade 1 wide stile concealed vertical rod device in classroom function if the opening also needs keyed outside trim.
10) Will the Von Duprin 9847WDC-4ft work on a narrow stile aluminum storefront door?
No. The 9847WDC-4ft is a wide stile device with an 8 inch x 2-3/4 inch x 2-3/8 inch center case, which will not fit a narrow stile rail. For narrow stile concealed vertical rod openings, the Adams Rite 8600 Series is built for aluminum doors, and the Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod device for 1-3/4 inch doors. The DORMA 9600BB is another narrow stile pushpad concealed vertical rod device, Grade 1 and non fire rated.
11) What looks like a substitute for the Von Duprin 9847WDC-4ft but is not?
The Falcon 1491DT is the one to watch. It is a concealed vertical rod device in name, but its function is dummy trim with a 9970 pull, narrow stile, so it does not latch and cannot serve a panic opening the way the 9847WDC-4ft does with its 3/4 inch latch throw. The Corbin Russwin ED7800 is also a concealed vertical rod Grade 1 device but it is a narrow stile crossbar unit, not a push pad, where the 9847WDC-4ft is push pad style.
12) How much does the Von Duprin 9847WDC push pad stick out from the face of the door?
Projection is 3-13/16 inches off the door face, with a center case measuring 8 x 2-3/4 x 2-3/8 inches in a smooth case. That projection is what you check against a corridor clear-width calculation or a door that swings toward a wall, side light, or adjacent leaf.
13) What dogging options can I get on the Von Duprin 98/99 Series concealed vertical rod device?
Hex key dogging is standard, which holds the latches retracted during high-traffic periods. Eight choices are available in all: hex key standard, CD cylinder dogging, CDSI cylinder dogging with security indicator, HDSI hex dogging with security indicator, SD special center case dogging, LD less dogging, DI dogging indicator, and CI cylinder dogging indicator. Schools and offices that want the doors pushed open during the day but keyed control over it typically go CD; anywhere staff need to see at a glance whether the door is dogged, the SI indicator versions are the ones to pick. Note SD makes the device handed.
14) I need delayed egress on a wood door exit. Can the 9847WDC do that?
Yes, through the CX CHEXIT upgrade. Configured that way the device holds the door secure for 15 seconds after someone pushes the pad while a nuisance alarm sounds, which meets NFPA and IBC delayed egress requirements. It is the configuration used where a facility needs controlled egress, healthcare and retail loss prevention being the usual cases.
15) What is a comparable wide stile concealed vertical rod exit device to the Von Duprin 9847WDC?
Closest equivalents we carry are the Corbin Russwin ED5800, a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors that is exit only and accepts trim, and the DORMA 9100 Series, a Grade 1 heavy duty wide stile pushpad device covering 1-3/4 to 2-1/4 inch doors and also non-fire-rated. For wood doors specifically, the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod device built for wood. The BEST Precision 2801 Series is another wide stile option in the same family of devices.
16) Can I upgrade a Von Duprin 98/99 device already installed in my building instead of replacing it?
Retrofit kits cover a good part of the option list. CDSI and HDSI security dogging indicators, QEL quiet electronic latch retraction, and the RX request-to-exit and LX latchbolt monitoring switches are all available as field retrofits on the 98/99 Series. That matters for a facility adding access control to openings that were installed years earlier, since the device body stays in the door and the prep does not change.
17) What is the less bottom rod option on a concealed vertical rod device and when do I need the ES pullman latch?
Standard build is PL pullman latches top and bottom. Less bottom rod removes the floor strike and bottom rod, which is what facilities do when the threshold collects dirt or the floor strike keeps getting damaged by carts and traffic. With less bottom rod you order the ES top pullman latch, which is the version built for an electric strike application, and it is the only pullman selection valid with that option. The standard PL top and bottom selection does not apply to a less bottom rod build.
18) Will the 3/4 inch latch throw on the Von Duprin 9847WDC engage my existing top and bottom strikes?
Latch throw is 3/4 inch at both the head and the threshold. If the strikes already in the frame and floor were set for a 3/4 inch throw concealed vertical rod device, the latches will engage. Where you get into trouble is a different rod system with a different throw or a different strike location, in which case the frame and floor strikes get replaced along with the device rather than reused.
19) Is there a simpler exit only concealed vertical rod device instead of the Von Duprin 9847WDC-4ft with lever trim?
Yes. The 9847WDC-4ft is ordered with trim functions ranging from EO exit only through lever, knob, night latch and thumbturn configurations, so an exit only build is available within the same device. If a plainer device is wanted, the CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device in exit only function, matching the 48 inch size of the 9847WDC-4ft. The BEST Precision 2601 is an exit only non-handed concealed vertical rod device in narrow stile.
20) Which wide stile concealed vertical rod exit device covers doors thicker than 1-3/4 inches?
The DORMA 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device with a door thickness range of 1-3/4 inch to 2-1/4 inch. The Von Duprin 9847WDC-4ft is specified at 1-3/4 inch door thickness and ships with fasteners for wood or metal doors 1-3/4 inch and 2-1/4 inch thick.
21) For standardizing a school or hospital across Grade 1 concealed vertical rod exit devices, which peers match the Von Duprin 9847WDC-4ft on grade?
The 9847WDC-4ft is Grade 1. Peers at the same grade in concealed vertical rod include the Adams Rite 8500 Series wide stile for hollow metal doors, the Corbin Russwin ED5800 wide stile, the DORMA 9100 Series wide stile pushpad in heavy duty, and the Sargent MD8613F-LTRIM heavy duty device with hex dogging. The 9847WDC-4ft also uses hex key dogging as its standard configuration, with cylinder dogging and dogging indicator options available.
22) Which concealed vertical rod exit device suits a door where the stile width is uncertain?
The CRL Jackson 1285 push pad concealed vertical rod panic exit is listed for narrow, medium or wide stile applications in exit only function, which covers a range of rail widths. The Von Duprin 9847WDC-4ft is specifically a wide stile device at 48 inches with a 3-13/16 inch projection off the door face.
23) What finishes does the Von Duprin 9847WDC come in to match existing hardware in my building?
Twelve finishes, so matching an existing fleet of openings is usually straightforward: 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. 626 satin chrome and 630 satin stainless are the two that show up most on institutional work.
24) Can I get a Von Duprin push bar with braille or a glow-in-the-dark finish?
Yes. Bar option is a required selection with five choices: standard bar, BR braille pushbar, KN knurled bar, RSS emergency exit push bar, and SG safety glow pushbar. Knurled bars are the traditional tactile warning for a door leading to a hazardous area; SG safety glow helps locate the exit in a smoke or power-loss condition. All are ordered with the device, not added later.
25) What is the QM quiet mechanical option on a Von Duprin exit device?
QM is a yes/no selection made when ordering the 9847WDC that reduces the mechanical noise of the device operating. It is worth specifying on library, healthcare, and office corridor openings where a hard latching clack every time someone exits is a complaint waiting to happen. On the electrified side, QEL is the quiet version of electric latch retraction for the same reason.
26) What is the XP option on a Von Duprin concealed vertical rod exit device?
XP is a patented 2-piece latchbolt design offered as an upgrade configuration on the 9847WDC. It is the choice on high-abuse openings, schools in particular, where the latch takes a beating from doors being forced or pulled against the latch.
27) What is the difference between the Von Duprin 9847WDC-4ft and the BEST Precision 2801 concealed vertical rod device?
Both are wide stile concealed vertical rod exit devices. The BEST Precision 2801 is in the 2800 Series; the 9847WDC-4ft is in the Von Duprin 98 and 99 Series, is non-handed, and carries a 3/4 inch latch throw with an 8 inch x 2-3/4 inch x 2-3/8 inch center case. The 9847WDC-4ft is ordered in finishes from 605 bright brass through 626 satin chrome, 630 satin stainless steel and 711 flat black.
