Von Duprin 9847EO-F 3 US26D – Frequently Asked Questions

1) Will the Von Duprin 9847F fit a 1-3/4 inch hollow metal door?
Yes. The 9847F-3ft is built for 1-3/4 inch doors, and that is the only thickness it covers. The 36 inch device suits a 3 ft leaf on single or double metal doors. Fasteners ship for wood or metal doors 1-3/4 inch and 2-1/4 inch thick, but the device itself is a 1-3/4 inch application and it is not rated for wood doors.
2) Why does the 9847F come less dogging?
Because it is a fire rated device. Mechanical dogging holds the latches retracted, which is not permitted on a fire rated opening, so the 9847F-3ft is supplied less dogging and the latches stay active at all times. If you want a door that can be held push-pull during the day, you need a non-fire-rated device on a non-rated opening, such as the Adams Rite 8500 Series concealed vertical rod.
3) Do I have to specify handing on the Von Duprin 9847F?
The device itself is non-handed in standard configurations, but you still pick RHR (right hand reverse) or LHR (left hand reverse) when ordering, because trim and certain options follow the door swing. A few options, such as SD or SS, do affect handing. Get the hand off the door as it swings out toward you in the direction of egress.
4) When should I order LBR (less bottom rod) on a concealed vertical rod device?
LBR drops the bottom rod and latch so nothing drags on the floor, which matters on openings with carpet, uneven thresholds, or where debris jams a bottom bolt. On the 9847F the standard build has a 5/8 inch bottom bolt (the 47 suffix). Two LBR choices are offered: plain LBR for the first leaf, and LBR-AFL for the second leaf, which adds the auxiliary fire pin needed to keep the pair fire rated. On a pair, order the AFL version on the inactive leaf.
5) Does the Von Duprin 9847F latch a pair of doors without a mullion?
Yes. A concealed vertical rod device latches into a strike at the head and, with the bottom bolt in place, at the threshold, so it secures a pair with no center mullion. The rods run inside the door, so nothing shows on the face. On the 9847F the top latch has a 3/4 inch throw and the bottom bolt is 5/8 inch.
6) Is the Von Duprin 9847F approved for a fire rated exit door in a school or hospital?
Yes. The 9847F-3ft is listed to ANSI/UL 10C and CAN/ULC-S104 for fire rated openings, and also certified to ANSI/UL 305 and CAN/ULC-S132. It carries ANSI/BHMA A156.3 2014 Grade 1, the top grade for exit devices, which is what most institutional specs call for on high traffic egress doors.
7) Can I add access control or electric latch retraction to the Von Duprin 9847F later?
Yes, and you can also specify it up front. Latch retraction choices are EL electric, QEL quiet electric, and PN pneumatic. Switch options include RX request to exit, LX latchbolt monitor, LX-RX combined, WP-RX waterproof, RX-LC low current, RX-2 double RX, SS signal switch, and ALK alarm kits with or without RX or LX. Von Duprin also publishes retrofit kits so a mechanical device can be converted as the access control scope grows.
8) Does the Von Duprin 9847F meet the 5 pound ADA operating force requirement?
Only with the AX option, which is offered on this device and is certified to the 5 lb force requirement under 2010 ADA Chapters 404.2.7 and 30934 and the 2013 California Building Code Chapter 11B-309.4. Select AX = Yes at order if your spec calls for accessible operating force.
9) Can I put the Von Duprin 9847F on a wood door, and if not what concealed vertical rod device works there?
The 9847F-3ft is not wood door compatible. For a wood door application, the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod exit device made for wood doors. Confirm the fire rating requirement of the opening separately, since the 9847F-3ft carries a fire rating and you will want that verified on whatever goes onto the wood door.
10) The 9847F does not fit my aluminum storefront stile. What concealed vertical rod device should I use instead?
The 9847F-3ft is a wide stile device with a center case of 8 inches by 2-3/4 inches by 2-3/8 inches and a 3-13/16 inch projection, which needs the stile width a hollow metal door provides. For narrow stile aluminum doors, the Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod device made specifically for aluminum doors. Other narrow stile Grade 1 options include the Corbin Russwin ED4800 and the Falcon 24-C, both narrow stile concealed vertical rod devices for 1-3/4 inch doors. Confirm the fire rating requirement for your opening separately, since the 8600 Series is not fire rated.
11) My opening is not fire rated. Do I still need the 9847F or is there a simpler concealed vertical rod device?
The 9847F-3ft carries a fire rating and is supplied less dogging, which is the configuration required on fire openings where dogging is not permitted. On a non-fire opening you do not need that, and several Grade 1 concealed vertical rod devices are built without a fire rating. The Adams Rite 8500 Series is a Grade 1 wide stile concealed vertical rod device for hollow metal doors with no fire rating, and the DORMA 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device, also non-fire rated, covering doors 1-3/4 inch to 2-1/4 inch thick. The DORMA thickness range is broader than the 1-3/4 inch the 9847F-3ft is specified for.
12) Is there another fire-rated wide stile concealed vertical rod exit device besides the Von Duprin 9847F and the Sargent?
Yes. The Adams Rite 3600 Series is a fire-rated Grade 1 wide stile concealed vertical rod exit device built for hollow metal doors, and the Adams Rite 3900 Series is a fire-rated Grade 1 wide stile concealed vertical rod device carrying a 1-1/2 hour rating. Both share the fire rating, Grade 1 certification and wide stile designation of the 9847F-3ft. Where the Von Duprin differs is in the option set you order it with: it is offered with electric latch retraction including QEL, switch packages such as RX, LX and LX-RX, and bar options including braille, knurled and safety glow pushbars, so if the opening is tied to access control or a specific pushbar, verify the Adams Rite can be configured the same way.
13) I need dogging on my concealed vertical rod device. The 9847F is less dogging, what else is there?
The 9847F-3ft is supplied less dogging because it is a fire-rated device and dogging is not permitted on fire openings. If the opening is not fire rated and you want mechanical dogging, the Sargent MD8613F-LTRIM is a heavy duty Grade 1 concealed vertical rod device for 36 inch by 84 inch metal doors with hex dogging. Confirm your opening is not fire rated before specifying a dogged device.
14) How much does the 9847F stick out into the corridor?
Projection is 3-13/16 inches from the door face, with a center case measuring 8 x 2-3/4 x 2-3/8 inches. That projection is worth checking against corridor clear width and against anything mounted nearby, like a wall stop or a low energy operator arm.
15) What trim do I order with the 9847F, and can I get a lever with a key cylinder?
Trim function runs from exit only and dummy trim through knob and lever sets: K, K-BE, K-NL, L, L-BE, L-KC, L-NL, plus NL, NL-OP, TL, TL-BE, TP and TP-BE. Night latch functions (NL, K-NL, L-NL) give key retraction of the latch from outside; L-KC is the key capture lever. If you pick an L trim you also choose the lever design: 06 is the default, with 01, 02, 03, 05, 07, 17 and 18 also offered.
16) Is there a quieter option for the 9847F on a hospital or dorm corridor?
Two. QM (Quiet Mechanical) is a yes/no selection on the device itself and cuts the mechanical noise on operation. If the door is electrified, QEL quiet electric latch retraction is the quiet alternative to standard EL. Both are ordered as options on the 9847F rather than as separate parts.
17) How does the Von Duprin 9847F compare to the Sargent 8600 Series concealed vertical rod device?
Both are Grade 1 wide stile fire rated concealed vertical rod devices. The Sargent 12-MD8613 is a classroom function device with a fire rating; the 9847F-3ft is ordered by trim function instead, with a wide list running from exit only through night latch and lever options. On the Von Duprin side the fire rated build is less dogging, while Sargent's MD8613F-LTRIM for 36 x 84 metal doors is catalogued with hex dogging. Pick on which function and dogging arrangement your opening and code official require.
18) I need delayed egress on a fire rated exit. Can the 9847F do that?
Yes, with the CX (CHEXIT) option. It holds the door 15 seconds after a request to exit while a nuisance alarm sounds, and meets NFPA and IBC delayed egress requirements. Specify CX at order rather than adding a separate delayed egress unit to the opening.
19) I only need exit only with no outside trim. Is there a cheaper concealed vertical rod device than a full 9847F?
The 9847F-3ft is ordered with a trim function, and exit only is one of the choices, so you can specify it as an EO device without outside trim. If you would rather order a device that is built exit only from the start, the Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors in an exit only function that also accepts trim, and the BEST Precision 2601 Series is a non-handed narrow stile concealed vertical rod device in exit only. Note the 2601 is narrow stile, so it is not a direct fit where a wide stile device is called for.
20) What is the difference between the Von Duprin 9847F and the Corbin Russwin ED7800 concealed vertical rod device?
The two differ in both stile and actuator. The 9847F-3ft is a wide stile device with a push pad style actuator. The Corbin Russwin ED7800 is a Grade 1 narrow stile concealed vertical rod device with a crossbar actuator, for 1-3/4 inch doors, in an exit only function that accepts operator trim. Both are for 1-3/4 inch thick doors. Choose based on the door: wide stile hollow metal with a push pad points to the 9847F, a narrow stile door where a crossbar is specified points to the ED7800.
21) Will a CRL Jackson 1085 work in place of a Von Duprin 9847F on a 36 inch door?
Not as a direct swap. The CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device in an exit only function, so it is sized for a wider opening than the 36 inch the 9847F-3ft covers, and it is exit only rather than accepting the range of trim functions the Von Duprin offers. The CRL Jackson 1285 is a push pad concealed vertical rod panic exit that suits narrow, medium or wide stile, also exit only. Both are panic devices; if your opening is fire rated, note that the 9847F-3ft carries a fire rating and is supplied less dogging for that reason.
22) What finishes does the Von Duprin 98/99 Series exit device come in for matching existing hardware?
Twelve finishes: 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, 643E aged bronze, 710 dark bronze anodized and 711 flat black. For institutional corridors 626 and 630 are the usual standardization choices.
23) What push bar styles are available besides the standard bar?
Five choices on the 9847F: standard bar, BR braille pushbar, KN knurled bar, RSS emergency exit push bar, and SG safety glow. Knurled bars are the tactile warning common on doors leading to hazardous areas, and safety glow helps in a smoke or power loss condition.
24) For standardizing exit devices across a facility, how does the Von Duprin 9847F compare to the BEST Precision 2801?
The BEST Precision 2801 is a wide stile concealed vertical rod exit device, the same basic configuration as the 9847F-3ft. The Von Duprin gives you more standardization levers on a single platform: it is Grade 1 and fire rated, non-handed in standard configurations, and offered across twelve finishes from 605 bright brass through 630 satin stainless and 711 flat black, with fifteen trim functions and upgrade paths including AX accessible operation and CX delayed egress. If your facility mixes fire and non-fire openings and you want one device family and one finish across all of them, that breadth is the reason to specify the Von Duprin.
