Von Duprin 9847EO 4 US26D – Frequently Asked Questions

1) Will the Von Duprin 9847 concealed vertical rod exit device work on a 1-3/4 inch hollow metal door?
Yes. The 9847 is built for metal doors and covers a 1-3/4 inch to 2-1/4 inch thickness range, with fasteners in the box for both 1-3/4 inch and 2-1/4 inch doors. Note that it is not rated for wood doors, so if the opening is a wood door you want a different device.
2) Do I need to specify handing when I order a Von Duprin 9847?
The 9847 ships non-handed in its standard configuration, so one device covers either swing. Handing only becomes a real selection when you take the SD (special center case dogging) or SS (signal switch) options, which are built hand-specific. Both RHR and LHR are offered when you need to call it out.
3) How do I hold the doors unlocked during the school day with a Von Duprin 9847?
Hex key dogging is standard on the 9847, which holds the latchbolts retracted so the doors push-pull freely during high-traffic hours. If you would rather control that with a key instead of an allen wrench, CD cylinder dogging is an option, and CDSI or HDSI add a security indicator so staff can see at a glance whether the device is dogged. LD (less dogging) is there for openings where dogging is not permitted, and DI or CI cover dogging indication on their own.
4) Will the Von Duprin 9847 latch into my existing strike?
Latch throw on the 9847 is 3/4 inch at both the top and bottom latch points. Because it is a concealed vertical rod device, it does not use an edge strike at all, it needs a top strike in the frame head and a bottom strike or threshold strike at the floor. Rim device strikes on the jamb will not transfer over.
5) How do I get outside trim on a Von Duprin 9847, and what are my options?
The 9847 takes trim as an ordering choice, not an afterthought. Exit only (EO) leaves no outside operation. For entry from the pull side you can specify a lever (L), knob (K), thumbpiece (TP), thumbturn (TL), or night latch (NL and NL-OP with optional pull). Combinations are offered too, L-NL, K-NL, L-KC key capture, and blank escutcheon versions (L-BE, K-BE, TL-BE, TP-BE) for openings where you want the plate without an operator. DT dummy trim and the K-DT and L-DT combinations cover the inactive leaf. If you pick an L trim you also choose the lever design: 01, 02, 03, 05, 06 (default), 07, 17, or 18.
6) Does the Von Duprin 9847 meet the 5 pound ADA operating force requirement?
Only if you order it with the AX accessible device option. AX is certified to the 5 lb force requirement of the 2010 ADA (Chapters 404.2.7 and 30934) and the 2013 California Building Code Chapter 11B-309.4. The base device is not the AX device, so on an opening where accessible operating force is on the drawing, AX has to be called out at order time.
7) The Von Duprin 9847 is not fire rated - what concealed vertical rod device should I use on a fire rated opening?
The Von Duprin 9847-4ft carries a Grade 1 certification and is not fire rated. For a fire rated opening, the Adams Rite 3600 Series is a fire rated Grade 1 wide stile concealed vertical rod exit 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. On the wide stile side with a keyed function, the Sargent 12-MD8613 is a fire rated Grade 1 concealed vertical rod device in classroom function. All three keep the concealed rod configuration, so the door prep concept stays the same as the 9847.
8) Will a Von Duprin 9847 fit a narrow stile aluminum storefront door?
The Von Duprin 9847-4ft is a wide stile device, sized for a wide stile door with a 48 inch push pad and a center case of 8 inches by 2-3/4 inches by 2-3/8 inches. A narrow stile aluminum storefront needs a narrow stile device instead. The Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod exit device for aluminum doors. The Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod device for 1-3/4 inch doors in exit only or accepts trim form, and the DORMA 9600BB Series is a Grade 1 narrow stile concealed vertical rod pushpad device, 36 inch, covering 1-3/4 inch to 2-1/4 inch doors. Glass front installers working aluminum stile doors should be specifying from that group rather than the 9847.
9) What is the closest wide stile concealed vertical rod alternative to the Von Duprin 9847 for a metal door?
The Von Duprin 9847-4ft is a wide stile concealed vertical rod exit device certified to ANSI/BHMA Grade 1, with a 48 inch push pad and hex key dogging standard. The DORMA 9100 Series is also a Grade 1 wide stile concealed vertical rod pushpad device, rated heavy duty, and covers a 1-3/4 inch to 2-1/4 inch door thickness range - the same range the 9847 carries. The Corbin Russwin ED5800 is another Grade 1 wide stile concealed vertical rod device, listed for 1-3/4 inch doors, in an exit only or accepts trim configuration. Both sit on the same door and do the same job as the 9847; the 9847 differs in offering the trim function range from exit only through lever, knob, thumbturn, thumbpiece and night latch on one model.
10) What concealed vertical rod exit device should I use on a wood door instead of the Von Duprin 9847?
The Von Duprin 9847-4ft is specified for metal doors and is not a wood door device, though its fasteners are supplied for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Where the leaf itself is wood, the BEST Precision 2701 Series is a wide stile concealed vertical rod exit device built reversible for wood doors, which keeps the wide stile push pad format and the concealed rod configuration you get on the 9847.
11) For a classroom door needing keyed outside trim, how does the Von Duprin 9847 compare to the Sargent 8600 concealed vertical rod device?
The Sargent 12-MD8613 is a Grade 1 wide stile concealed vertical rod device in classroom function and is fire rated. The Von Duprin 9847-4ft is a Grade 1 wide stile concealed vertical rod device that is not fire rated, and it is ordered with the outside operation chosen at the trim function - lever with a choice of 01, 02, 03, 05, 06, 07, 17 or 18 lever design, knob, thumbturn, thumbpiece, night latch, or key capture lever. Where the opening is a fire rated classroom door, the Sargent 12-MD8613 is the one carrying the fire rating.
12) Should I use a concealed vertical rod device or a rim device on a pair of doors?
A concealed vertical rod device like the 9847 latches at the head and the threshold on each leaf, so a pair can be secured with no center mullion and no exposed rods on the face of the door. That is the reason it gets specified in schools, hospitals and government work where appearance and abuse both matter. A rim device only latches on the strike edge, so on a pair it needs a mullion or a second leaf with a vertical rod. The tradeoff with concealed rod is that the rods live inside the door, so the door has to be prepped for it and service means opening the door up.
13) How much clearance do I need in front of the door for the Von Duprin 9847 push pad?
Projection is 3-13/16 inches off the door face, and the center case measures 8 x 2-3/4 x 2-3/8 inches. That projection is the number that matters in a tight vestibule, a corridor with a swing-path conflict, or where the door opens toward a wall return.
14) Can I get access control or an electric latch retraction on the Von Duprin 9847?
Yes. QEL quiet electric latch retraction and EL electric latch retraction both pull the latches back on a signal, and PN pneumatic retraction is offered as well, which is what you use where the doors need to open on a card read or a push plate. For monitoring, RX gives request-to-exit signalling and LX monitors the latchbolt, with LX-RX combining both. Variants of RX cover specific conditions: WP-RX for wet or exterior locations, RX-LC for low current boards, and RX-2 for a double request to exit.
15) I need delayed egress on an exit door. Can the Von Duprin 9847 do that?
Yes, with the CX (CHEXIT) option. It meets NFPA and IBC requirements for delayed egress, with a 15 second door hold and a nuisance alarm. That is the configuration for openings where you need to slow an unauthorized exit without defeating egress, common in healthcare and retail loss prevention. Alarmed exit is a separate path: ALK gives an alarm exit kit, with RX-ALK and LXRX-ALK adding the switches.
16) I only need push to exit with no outside trim - is there a simpler option than the Von Duprin 9847?
The Von Duprin 9847-4ft is offered in an exit only trim function alongside its lever, knob, thumbturn, thumbpiece and night latch options, so it can be ordered as a pure egress device. If the opening will never take outside trim, several peers are built exit only from the start. The CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device in exit only function - the same 48 inch push pad width as the 9847 and, like the 9847, non-handed in standard form. The BEST Precision 2601 Series is a non-handed narrow stile concealed vertical rod device in exit only form, and the Falcon 1990EO is a Grade 1 narrow stile concealed vertical rod exit only device at 44 inches for 1-3/4 inch doors.
17) Is a crossbar concealed vertical rod device the same as the Von Duprin 9847?
No. The Von Duprin 9847-4ft is a push pad style device with a 48 inch pad and a smooth mechanism case, and its projection off the face of the door is 3-13/16 inches. The Corbin Russwin ED7800 is a Grade 1 concealed vertical rod device as well, but it is a crossbar device on a narrow stile, in exit only or accepts operator trim form for 1-3/4 inch doors. The rods and the egress function are comparable; the actuating hardware the occupant touches and the stile it mounts on are not, so a crossbar device is not a drop-in for a push pad opening.
18) What looks like a Von Duprin 9847 substitute but will not give me a working exit device?
Watch the dummy trim entries. The Falcon 1491DT is a narrow stile concealed vertical rod device in dummy function with a 9970 pull at 42 inches - it looks like an exit device on the door but does not latch or provide panic egress, and it is a narrow stile part. The Von Duprin 9847-4ft carries a dummy trim option among its trim functions too, but its standard forms are working panic hardware with a 3/4 inch latch throw. On a pair of doors the dummy device belongs on the inactive leaf only; ordering it for the active leaf leaves the opening without egress hardware.
19) We standardize on hex key dogging across the building - which other concealed vertical rod devices match that?
The Von Duprin 9847-4ft ships with hex key dogging as standard, with cylinder dogging, dogging indicator and less dogging available as ordered options. The Sargent MD8613F-LTRIM is a heavy duty Grade 1 concealed vertical rod device for metal doors that also uses hex dogging, sized for a 36 by 84 inch door with lever trim. For a facility standardizing dogging method and key control across openings, that keeps one dogging tool in the maintenance kit across both devices.
20) I have a mix of narrow, medium and wide stile doors - can one concealed vertical rod device cover all of them instead of the Von Duprin 9847?
The Von Duprin 9847-4ft is a wide stile device, so it is specified per opening by stile. The CRL Jackson 1285 push pad concealed vertical rod panic device is listed for narrow, medium or wide stile in exit only function, which lets a single model cross a mixed set of stiles where no outside trim is required. Where the opening needs outside operation - lever, knob, thumbturn, thumbpiece or night latch - the 9847 covers those trim functions on a wide stile door.
21) What is the difference between the Von Duprin 9847 and the Adams Rite 8500 for a hollow metal door?
Both are Grade 1 wide stile concealed vertical rod exit devices without a fire rating. The Adams Rite 8500 Series is built for hollow metal doors. The Von Duprin 9847-4ft is a 48 inch push pad device with a smooth mechanism case, non-handed in standard configuration, a 3/4 inch latch throw, and a door thickness range of 1-3/4 inch to 2-1/4 inch. The 9847 is also offered across finishes from 605 Bright Brass through 630 Satin Stainless Steel and 711 Flat Black, and across trim functions from exit only to lever and night latch.
22) I need a shorter concealed vertical rod device than the 48 inch Von Duprin 9847 - what covers a 36 inch door?
The Von Duprin 9847-4ft is built around a 48 inch push pad. For a narrower leaf, the DORMA 9600BB Series is a 36 inch Grade 1 narrow stile concealed vertical rod pushpad device for 1-3/4 inch to 2-1/4 inch doors, the Falcon 24-C Series is a 36 inch Grade 1 narrow stile concealed vertical rod device in exit only function for 1-3/4 inch doors, and the Falcon 1690EO is a 3 ft Grade 1 narrow stile concealed vertical rod exit only device. All three are narrow stile parts, so confirm the stile width on the door before ordering against a wide stile opening.
23) Is the BEST Precision 2801 an equivalent to the Von Duprin 9847?
The BEST Precision 2801 Series is a wide stile concealed vertical rod exit device, so it sits in the same family as the Von Duprin 9847-4ft, which is a wide stile concealed vertical rod device certified to ANSI/BHMA Grade 1 with a 3/4 inch latch throw, non-handed as standard, for commercial metal doors. The 9847 is ordered in a 48 inch push pad size with a smooth mechanism case, and adds field-configurable RX, LX, QEL and CX options along with the AX accessible device option meeting the 5 lb force requirement of the 2010 ADA. Confirm the door thickness and the outside trim needed before treating either as a swap for the other.
24) How do I match the Von Duprin 9847 to the finishes already on my building's doors?
Twelve finishes are offered, called out by ANSI/BHMA number so they match across brands: 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. If you are standardizing a fleet of openings, 626 and 630 are the usual institutional choices and the finish code on your existing hardware is what to match to.
25) What is the difference between the Von Duprin 98 and 99 series push bars?
It is the look of the mechanism case. The 9847 uses the 98 Series smooth case; the 99 Series is the same device family with a grooved case. Function, grade and dimensions do not change with the choice, so it comes down to matching what is already installed elsewhere in the building or what the architect drew.
26) Can I get a Braille or glow-in-the-dark push bar on the Von Duprin 9847?
Yes. Beyond the standard bar, the 9847 offers BR with a Braille pushbar, SG safety glow for low-light egress, KN knurled bar as a tactile hazard warning, and RSS emergency exit push bar. Knurled and Braille bars come up on accessibility and life-safety specs, so they are worth pinning down before the order goes in rather than after.
27) How do I quiet down an exit device that slams in a corridor?
Order the 9847 with the QM quiet mechanical option, which dampens the push pad return stroke. Von Duprin also builds a fluid damper into the 98/99 Series for the same purpose. On the electrified side, QEL is the quiet version of electric latch retraction, which matters in a library, a hospital ward corridor, or anywhere the device cycles all day next to occupied space.
