Von Duprin 99EO-F 4 US26D – Frequently Asked Questions

1) Will the Von Duprin 99 latch into my existing rim strike?
The 99 throws a 3/4 inch latchbolt into a surface mounted rim strike on the frame or on the mullion. If your current opening already runs a rim device with a rim strike at that throw, the geometry lines up; if you are coming off a vertical rod or mortise device, there is no rim strike on the frame and you will be adding one.
2) Do I need to specify handing when ordering a Von Duprin 99F rim device?
The 99 rim device is non-handed by design, but handing gets specified on the order because certain options are handed, including SD special dogging, -2 double cylinder, and SS signal switch. Handing choices are RHR and LHR. If you are adding lever trim or any of those options, get the hand right off the door.
3) Can I put a Von Duprin 99 rim device on a pair of doors?
Yes, with a mullion. A rim device latches into a strike on the frame, so a pair needs a removable or fixed mullion for the inactive side to strike against. If you cannot have a mullion in the opening because of equipment or gurney traffic, go to a vertical rod configuration instead, which the 98/99 platform also offers as surface vertical rod (27), concealed vertical rod (47 and 48), and concealed vertical cable (49).
4) Can I get a Von Duprin 99 rim exit device with lever trim for classroom or storeroom outside access?
Yes. Trim functions include lever (L), lever with blank escutcheon, lever key capture, lever night latch, knob and knob variants, thumbpiece, night latch, night latch with optional pull, dummy trim, and exit only. If you pick an L trim you also choose the lever design: 01, 02, 03, 05, 06, 07, 17, or 18. Exit only (EO) is the choice when nothing should open the door from outside.
5) How do I tie a Von Duprin 99 exit device into an access control system?
Order it with the electric options rather than retrofitting later. Latch retraction comes as EL electric latch retraction, QEL quiet electric latch retraction, or PN pneumatic, which lets a card reader or timer pull the latch and leave the door on free pull. For monitoring, the switch options are 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 the ALK alarm kit versions. Delayed egress is the CXA 15 second delay option.
6) Can I dog down a Von Duprin 99F to hold the door on free pull during business hours?
Not mechanically. The 99F ships less dogging, which is standard for fire devices since a fire door has to latch every time. If you need the door on push-pull during the day and the opening is rated, the route is electric latch retraction (EL or QEL) on a timer or access control schedule, not dogging. If the opening is not fire rated, a non-rated device with hex key dogging, such as the Design Hardware 1000R, does the job mechanically.
7) Is the Cal-Royal A9820 a direct substitute for the Von Duprin 99F on a fire rated door?
No. The Cal-Royal A9820 is a 48 inch rim exit device, exit only, heavy duty, but it is not fire rated and carries a Grade 2 rating. The Von Duprin 99F-4FT is fire rated and Grade 1. Matching the 48 inch size alone does not carry a fire door; the label requires a fire rated device. The Cal-Royal 5500 is likewise a 48 inch push bar unit that is not fire rated.
8) The door is a wood fire door - will the Von Duprin 99F-4FT work?
The Von Duprin 99F-4FT is not wood door compatible. Among fire rated rim devices, the Adams Rite 3700 is a Grade 1 fire rated narrow stile rim device listed as wood door compatible; the Adams Rite 8700 is also wood door compatible but is not fire rated. Marks USA M9900F-48, Orca OED85 and Arrow FS1250 are fire rated but are not wood door compatible, so they do not solve a wood leaf either.
9) Can I put the Von Duprin 99F on an aluminum storefront door, or do I need a narrow stile device?
The Von Duprin 99F-4FT 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 a stile deep enough to carry that case. Narrow stile alternatives for a glass front leaf include the Adams Rite 3700, a fire rated Grade 1 narrow stile rim device with starwheel interlocking, and the non-fire Adams Rite 8700 and 8800; the 8800 covers doors 1-3/4 inch to 2-1/4 inch. Corbin Russwin ED4200 and Falcon 19-R are Grade 1 narrow stile rim devices for 1-3/4 inch doors. Only the Adams Rite 3700 among these carries a fire rating.
10) What is the closest fire rated 48 inch rim exit device to the Von Duprin 99F-4FT?
The Marks USA M9900F-48 is the nearest one-for-one match: a 48 inch fire rated rim panic exit device, exit only, with a panic protector end cap. The Von Duprin 99F-4FT is also a fire rated rim device at a 48 inch product size, Grade 1, with a 3/4 inch latch throw and a non-handed chassis. The difference that matters on a spec is trim: the Marks unit is exit only, while the 99F-4FT is ordered with trim functions including EO exit only, L lever, K knob, NL night latch and TP thumbpiece. If the opening needs outside key or lever access, the exit-only unit will not cover it.
11) The opening is a fire door but the leaf is only 36 inches wide - what fire rated rim device fits instead of the 48 inch Von Duprin 99F?
For a narrower fire door leaf, the Marks USA M9900F-36 is a 36 inch fire rated rim panic exit device, exit only, and the Orca Hardware OED85 is a 36 inch fire rated rim exit device, also exit only. The Arrow FS1250 is a 32 inch fire rated rim exit device for doors 1-3/4 inch thick. The Von Duprin 99F-4FT is sized at 48 inches, so the push pad run is matched to a wider leaf; the Dexter ED1000-R-F-EO is another Grade 1 fire rated rim option to consider.
12) I need electric latch retraction on the exit device - what are my options besides the Von Duprin 99F with QEL?
The Von Duprin 99 Series takes EL, QEL quiet electric latch retraction, or PN pneumatic latch retraction as an ordered option on a fire rated Grade 1 chassis. Electrified alternatives include the SDC Spectra S6136, a 36 inch electrified architectural rim exit device with a 4 inch wide stile for doors 1-3/4 inch to 2 inch; the Dormakaba E2103 electrified 36 inch rim device with 4908A classroom trim; and the Securitron EMB electromechanical exit bar for 2-1/4 inch doors. None of those three is listed fire rated, so on a labeled opening the 99F chassis is the one that carries the rating.
13) How much does the Von Duprin 99 stick out from the door face, and how much wall clearance do I need?
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. That is what you check against a return wall, an adjacent door in a vestibule, or anything in the swing path before you commit to a wide stile device.
14) What is the AX option on a Von Duprin 99 and do I need it for ADA?
AX is the accessible upgrade that brings operating force down to the 5 lb. requirement of the 2010 ADA (Chapters 404.2.7 and 30934) and the 2013 California Building Code (Chapter 11B-309.4). If your project is being reviewed against those force limits, specify AX at order time. It is a build option, not a field kit.
15) Is a Grade 2 exit device good enough, or do I need Grade 1 like the Von Duprin 99?
For school corridors, hospitals, and government buildings the 99F is the Grade 1 answer, certified to ANSI/BHMA A156.3 2014 Grade 1 and listed to UL 305 and CAN/ULC-S132 for panic. Grade 2 devices such as the Cal-Royal 5000 and 5500 are cheaper duty class and are not fire rated, so they cannot go on a fire door at all. On a low-traffic non-rated back door, Grade 2 is defensible; on a rated egress path in an institution it is not.
16) Which 48 inch rim exit devices can I use on a non-fire opening in place of the Von Duprin 99F-4FT?
On an opening with no fire label, the wide stile 48 inch options include the Corbin Russwin ED3200, a Grade 1 crossbar rim exit device for doors 1-3/4 inch thick; the DORMA 9300A, a Grade 1 heavy duty wide stile rim device, exit only, for doors 1-3/4 inch to 2-1/4 inch; the CRL Jackson 1095 crossbar rim panic device, exit only; and the Cal-Royal 5500 push bar rim device. The Von Duprin 99F-4FT is fire rated and uses a push pad style actuator, so a crossbar unit changes the look of the door face as well as the label status.
17) What is the difference between the Von Duprin 99F and the Sargent 8800 fire rated wide stile rim device?
Both are Grade 1 fire rated wide stile rim exit devices for doors that are not wood. The Sargent 12-8810-LTRIM is configured as a dummy function unit with RX and MELR. The Von Duprin 99F-4FT is a live 48 inch device with a 3/4 inch latch throw, non-handed, and its switch and latch retraction options are selected at order time, including RX request to exit, LX latch bolt monitor, and QEL quiet electric latch retraction. If the opening needs a functioning latch, the dummy-configured Sargent will not do the job.
18) We need to standardize a school on one rim device family - what Grade 1 wide stile lines are comparable to the Von Duprin 99 Series?
Grade 1 wide stile rim exit device families that cover a facility include Corbin Russwin ED5200 and ED2200, both Grade 1 wide stile rim devices for 1-3/4 inch metal doors; DORMA 8300, a Grade 1 wide stile panic rim device; Detex Advantex 10 Series, Grade 1 extra heavy duty wide stile; and TownSteel ED1100, Grade 1 heavy duty wide stile. The Von Duprin 99F-4FT is Grade 1 wide stile and fire rated, and among this group only the 99F carries a fire rating, which matters where corridor and stair doors on the same standard are labeled.
19) Is a pressure sense bar or switch bar the same thing as a Von Duprin 99F rim exit device?
No. The SDC SureExit PSB560 is a pressure sense bar with tri-failsafe technology and the SDC MSB550 is a mechanical switch bar with electromagnetic lock release; both are 36 inch bars for narrow or wide stile doors that release an electric lock rather than throwing a mechanical latch, and neither is fire rated. The Von Duprin 99F-4FT is a mechanical rim latch device with a 3/4 inch latch throw that engages a strike, fire rated and Grade 1. They are not interchangeable on a labeled fire door.
20) Which rim exit devices are non-handed like the Von Duprin 99F, so I do not have to stock left and right?
The Von Duprin 99F-4FT is non-handed except when certain options are applied. Other non-handed or reversible rim devices include the BEST Precision 5101, described as a non-handed universal design; the BEST 2401 narrow stile exit only device, non-handed; the CRL Jackson 1295, a non-handed push pad rim panic device for 1-3/4 inch doors; and the Sargent 2828 and 3828, Grade 1 reversible wide stile rim devices for 48 inch minimum door width. Of these, the 99F is the fire rated one.
21) Can I use a concealed vertical rod device where the Von Duprin 99F rim device is specified?
Only if the door and frame are prepped for it. The Von Duprin 99F-4FT is a rim device, latching into a strike on the frame with a 3/4 inch throw. The Hager 4501 is a Grade 1 concealed vertical rod device with a wide stile push pad and the Hager 4601 is the Grade 1 narrow stile concealed vertical rod version; both latch top and bottom and require a door prepped for concealed rods, and neither is fire rated. The 98/99 Series itself is also built in concealed vertical rod configurations, which is the path that keeps the same family on the job.
22) Which finishes does the Von Duprin 99 series come in for matching the rest of a building?
Twelve finishes cover most standardization jobs: 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 630 and 626 are the usual matches to existing hardware.
23) What push bar options are there on the Von Duprin 99 besides the standard bar?
Five bar choices: the standard bar, BR braille pushbar, KN knurled bar, RSS emergency exit push bar, and SG safety glow pushbar. Knurled bars are the tactile warning bar used where code calls for a hazardous-area indication, and safety glow helps in a stairwell or corridor that goes dark on power loss. Also available is the QM quiet mechanical option and RGO rod guard.
24) What should I order for a matching inactive leaf or a pull-side dummy next to a Von Duprin 99F?
The Von Duprin 99F-4FT is ordered with a DT dummy trim function, which keeps the same grooved case and 48 inch push pad appearance on the leaf. If the dummy is being matched to a different family, the Detex Advantex 00 Series is a super heavy duty Grade 1 wide stile dummy exit device. A Detex dummy next to a Von Duprin active device will read as a different bar profile across the pair of leaves.
25) I only need a basic exit only rim device on a 48 inch non-labeled door - what is simpler than a Von Duprin 99F?
For a plain exit only opening with no label and no outside trim, the Dexter ED1000-R-EO-4FT is a 4 foot Grade 1 rim exit device, and the Sargent 3828 is a Grade 1 reversible standard push bar rim device for 48 inch doors. The Von Duprin 99F-4FT carries the fire rating plus the field options for switches, delayed egress and electric latch retraction, which an exit only unit does not include.
