Von Duprin 9848EO-F 3 US26D – Frequently Asked Questions

1) Will the Von Duprin 9848F fit a 36 inch wide door, and what door thickness does it need?
The 9848F-3ft is built for a 36 inch door opening and is specified for 1-3/4 inch thick doors. Fasteners ship with it for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. It is a wide stile device, so the door stile has to be wide enough to carry the 8 x 2-3/4 x 2-3/8 inch center case, and the device projects 3-13/16 inches off the door face, which matters where a door swings into a tight corridor or against a wall.
2) Is the Von Duprin 9848F fire rated, and what standards does it carry?
Fire rated, yes. The 9848F is UL listed for fire exit hardware under ANSI/UL 10C and CAN/ULC-S104, and it is certified to ANSI/BHMA A156.3 2014 Grade 1, with ANSI/UL 305 and CAN/ULC-S132 listings as well. Because it is fire exit hardware, it comes less dogging: fire doors must latch on every closing, so there is no mechanical hold-down of the push pad.
3) Can I use a concealed vertical rod exit device on a pair of doors without a mullion?
That is exactly what a concealed vertical rod device like the 9848F is for. It latches at the head and at the threshold with a 1-1/2 inch bottom bolt and a 3/4 inch latch throw, so a pair of doors can be secured with no center mullion and the full clear opening stays available. The rods run inside the door, so nothing is exposed on the face. If you would rather keep the rods out of the door entirely, a rim device with a removable mullion is the alternative, but it puts a post in the middle of your opening.
4) Does the Von Duprin 9848F meet ADA opening force requirements?
Only in the AX configuration. The AX accessible device option is ADA certified and meets the 5 lb force requirement under 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. AX is a yes/no selection at order time, so if the opening is on an accessible route, choose it up front.
5) What else could I use instead of the Von Duprin 9848F on a wide stile fire rated opening?
Wide stile fire rated concealed vertical rod alternatives include the Adams Rite 3600 Series for hollow metal doors and the Adams Rite 3900 Series with a 1-1/2 hour rating, both Grade 1. Sargent's 12-MD8613 is a Grade 1 wide stile fire rated CVR in a classroom function if you need keyed outside operation. The Corbin Russwin ED5800 is a Grade 1 wide stile CVR for 1-3/4 inch doors that accepts trim, though it is not carried here as fire rated. Watch the stile: the Adams Rite 8600, Corbin Russwin ED4800, and DORMA 9600BB are all narrow stile and will not substitute on a wide stile door.
6) My opening is not fire rated - is there a simpler concealed vertical rod device I can use instead of a 9848F?
Yes. On a non-rated wide stile opening the DORMA 9100 Series is a Grade 1 heavy duty concealed vertical rod pushpad device that is not fire rated and covers 1-3/4 inch to 2-1/4 inch doors. The Adams Rite 8500 Series is another non-rated Grade 1 wide stile concealed vertical rod for hollow metal doors. The Von Duprin 9848F-3ft is fire rated to begin with and is furnished less dogging; non-rated devices such as these are where mechanical dogging is normally available.
7) What is the closest fire rated wide stile concealed vertical rod equivalent to the Von Duprin 9848F if I need another brand for the same opening?
The Sargent MD8613F-LTRIM is the nearest match on a 36 inch metal door: it is a Grade 1 heavy duty concealed vertical rod device from the Sargent 80 Series sized for 36 inch by 84 inch metal doors. The Von Duprin 9848F-3ft is Grade 1, fire rated, wide stile, 36 inch, with a 3/4 inch latch throw. The Sargent is supplied with hex dogging, while the 9848F is a less dogging device, which is the normal arrangement for fire exit hardware. Also in fire rated wide stile Grade 1 are the Adams Rite 3600 Series and 3900 Series, the 3900 carrying a 1-1/2 hour rating.
8) The 9848F will not fit my narrow stile aluminum storefront door - what concealed vertical rod device should I use instead?
The Von Duprin 9848F-3ft is a wide stile device, so it is not the part for a narrow stile aluminum door. For narrow stile, the Adams Rite 8600 Series is a Grade 1 concealed vertical rod built for aluminum doors, and the DORMA 9600BB Series is a Grade 1 narrow stile pushpad concealed vertical rod in a 36 inch size for doors 1-3/4 inch to 2-1/4 inch. Both are non-rated, so confirm your opening does not require fire exit hardware before specifying either.
9) Is the 9848F handed, and do I still have to pick a hand when I order?
The device itself is non-handed, so one unit works on either swing. You still select RHR or LHR on the order because trim and some options are handed. One exception worth knowing: the SS signal switch option makes the device handed.
10) What outside trim options can I get with the Von Duprin 9848F?
Trim runs from exit only with no outside operation through night latch (NL and NL-OP), key capture, thumbturn (TL, TL-BE), thumbpiece (TP, TP-BE), knob (K, K-BE, K-NL), lever (L, L-BE, L-KC, L-NL), and dummy trim. If you pick an L lever function you also choose the lever design: 06 is the default, with 01, 02, 03, 05, 07, 17 and 18 also offered. For a classroom or stair-return opening most buyers land on L-NL or NL.
11) What electrical options can I add to a Von Duprin 9848F for access control?
For monitoring you can specify RX request-to-exit, LX latchbolt monitor, LX-RX combined, RX-2 double request-to-exit, RX-LC low current, WP-RX waterproof, or SS signal switch. For remote unlocking there is EL electric latch retraction, QEL quiet electric latch retraction, or PN pneumatic. Alarm kits are available as ALK, RX-ALK, or LXRX-ALK. Von Duprin also offers QEL, and CDSI/HDSI dogging indicators, as field retrofit kits, so an opening can be upgraded later without swapping the device.
12) I need delayed egress on a fire rated exit door. Can this device do it?
Yes, through the CX CHEXIT upgrade. With CHEXIT the door stays secure for 15 seconds after a request to exit while a nuisance alarm sounds, which meets NFPA and IBC requirements for delayed egress. Specify CX with the device rather than adding it later.
13) Will the 9848F hold up in a school or hospital corridor?
That is the environment the 98/99 Series is built for. It is a commercial Grade 1 device under ANSI/BHMA A156.3 2014, the top rating for exit devices, and the series is aimed at high-use, high-abuse institutional openings in schools, hospitals, and government buildings. For a fleet standardization program the field-configurable retrofit kits matter as much as the grade: you can add QEL latch retraction or CDSI/HDSI dogging indicators later without replacing the device.
14) Can I use the Von Duprin 9848F on a wood door, and what concealed vertical rod works if I cannot?
The 9848F-3ft is listed as not wood door compatible, though its fasteners are supplied for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. If the leaf is wood, the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod device specified for wood doors. Confirm the wood door assembly's own label rating separately from the device.
15) I only need push-to-exit with no outside trim - is there a cheaper alternative to a fully trimmed 9848F?
If the opening needs no outside operation, an exit only device avoids buying trim. The Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod furnished exit only and able to accept trim, for 1-3/4 inch doors. The BEST Precision 2801 Series is another wide stile concealed vertical rod option. The Von Duprin 9848F-3ft itself can be ordered in an EO exit only trim function alongside knob, lever, night latch and thumbpiece trims, so staying in the 98/99 Series without trim is also possible.
16) What concealed vertical rod devices look like a substitute for the 9848F but are not?
Two to watch. The Falcon 1491DT is a dummy trim narrow stile concealed vertical rod assembly with a 9970 pull at 42 inches - dummy function, so it does not latch and cannot serve an egress opening. The Corbin Russwin ED7800 is a Grade 1 narrow stile concealed vertical rod but uses a crossbar rather than a push pad; the Von Duprin 9848F-3ft is a push pad device on a wide stile door at 36 inches. Narrow stile Falcon exit only devices such as the 1690EO at 3 ft and the 24-C at 36 inches also share the size but not the stile.
17) My door is 48 inches wide - the 9848F is 36 inches. What concealed vertical rod fits?
The Von Duprin 9848F-3ft is built for a 36 inch opening. For a wider leaf, the CRL Jackson 1085 Series is a 48 inch non-handed concealed vertical rod panic exit device in exit only function for wide stile doors. The Falcon 1990EO is a 44 inch narrow stile exit only concealed vertical rod if the stile is narrow. Both are exit only, so outside trim would need to be addressed separately.
18) What finishes does the Von Duprin 9848F come in for matching existing doors in a building?
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 steel, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. For institutional corridors 626 and 630 are the usual standards; 628 aluminum is the common match on aluminum storefront openings.
19) What are the push bar options on the 9848F, and when would I need something other than the standard bar?
Beyond the standard push pad you can order BR braille, KN knurled, RSS emergency exit push bar, or SG safety glow. Knurled bars are a tactile warning at hazardous or restricted doors; safety glow helps locate the exit in a smoke or power-loss condition, which is worth considering on a fire rated egress opening.
20) What is the QM quiet mechanical option on the Von Duprin 9848F for?
QM is a yes/no selection that quiets the mechanical operation of the device. On a fire rated opening you cannot dog the pad down, so the device latches and re-latches on every cycle, and in a library, hospital ward corridor, or testing area that noise adds up. Pick QM there. If you need quiet plus remote unlocking, QEL is the quiet version of electric latch retraction.
21) I have a mix of stile widths across a building - is there one concealed vertical rod device that covers them all instead of specifying the 9848F per door?
The CRL Jackson 1285 push pad concealed vertical rod panic exit is listed for narrow, medium or wide stile and is an exit only device, which is the single closest thing to a one-spec answer across mixed stiles. The Von Duprin 9848F-3ft is specifically a wide stile device, fire rated and Grade 1, so for the labeled openings in that mix you would still be specifying a rated device door by door.
22) Does a narrow stile Grade 1 device like the Corbin Russwin ED4800 do the same job as the Von Duprin 9848F?
Only on a different door. The Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod for 1-3/4 inch doors, furnished exit only and able to accept trim. The Von Duprin 9848F-3ft is a wide stile fire rated Grade 1 device for 1-3/4 inch doors with a 3-13/16 inch projection and an 8 by 2-3/4 by 2-3/8 inch center case. The stile width and the fire rating are the deciding differences, not the grade.
