Von Duprin VON-9827-3-628 – Frequently Asked Questions
1) Will the Von Duprin 9827/9927 exit device fit a 36 inch wide, 1-3/4 inch thick hollow metal door?
Yes on both counts. The 3-foot 9827/9927 is sized for a 36 inch door and the device is specified for 1-3/4 inch thick doors. It is a wide stile push pad device, so it wants the lock stile of a hollow metal or wood door rather than an aluminum storefront rail. On stock hollow metal it covers doors already prepped with 86 or 161 cutouts, which means a door cut for a mortise lock (86) or a cylindrical lock (161) does not need the old prep patched before the device goes on.
2) I have a pair of doors with no center mullion. Will a Von Duprin 9827/9927 secure them?
That is exactly what a surface vertical rod is for. Each device latches into a strike at the head and a strike at the threshold instead of latching into the opposite leaf, so a pair with no mullion gets one device per leaf and both leaves are free to swing. A rim device on that same opening would need a mullion standing between the leaves to latch into. The 98/99 family covers single, double, and double egress openings, and the 27 suffix in 9827/9927 is the surface mounted vertical rod version.
3) Surface vertical rod or concealed vertical rod: which should I use on my exit doors?
Surface rods, which is what the 9827/9927 is, run the rods and latches on the face of the door. That makes it the option for a door that was never prepped for concealed hardware, and everything stays reachable for adjustment and service. Concealed hides the rods inside the door for appearance and keeps them out of the way of cart traffic, but the door has to be prepped for it. Within the 98/99 family the same push pad is available as 47 concealed vertical rod with a 5/8 inch bottom bolt, 48 concealed with a 1-1/2 inch bottom bolt, 47WDC concealed for wood doors, 49 concealed vertical cable, 50WDC wood door concealed cable, 52 one-point concealed cable, 57 three-point latching, 75 mortise lock, or with no suffix as a rim device.
4) Can the Von Duprin 9827/9927 be used on a fire-rated door?
Only in the fire version, which you get by adding the -F suffix to the device. Fire rated 98/99 devices are the ones certified to ANSI/UL 10C and CAN/ULC-S104. The standard, non-fire device carries ANSI/UL 305 and CAN/ULC-S132 as panic hardware. One practical consequence: the hex key dogging that comes standard on the panic device is not permitted on a fire door, because a fire exit device has to latch every time the door closes. Order the fire version knowing the door will always latch and never hold open on the push pad.
5) What trim do I order with a 9827/9927, and can one device do both exit only and night latch?
The device ships field selectable between EO (exit only), DT (dummy trim) and NL (night latch), so that decision can be made at install rather than on the order. If you are running thumbpiece, knob, or lever trim (TP, K or L), you remove the NL drive screw from the device. Trim itself splits two ways: the 990 is pull trim, with classroom (TP), storeroom (NL), dummy (DT), passage (TP-BE) and exit only (EO); the 996 is knob or lever trim, with classroom (L, K), storeroom (L-NL, K-NL), dummy (L-DT, K-DT) and passage (L-BE, K-BE). Storeroom means the key retracts the latch and the lever stays rigid. Classroom means the key locks and unlocks the lever.
6) Is the Von Duprin 9827/9927 handed, or will one device work on either leaf?
Non-handed as it comes, so the same device goes on a left hand or right hand door and you can stock one part for a building. It becomes handed only when certain device options are specified: SD special dogging, SS signal switch, or WS for tornado and hurricane applications. If you are ordering any of those three, the hand has to be called out.
7) How far do the latches on the 9827/9927 throw, and will the bottom bolt still catch over a threshold?
Latch throw is 5/8 inch. That is all the travel the bottom bolt has into the floor strike, so the strike has to sit within 5/8 inch of the end of the rod when the door is closed. On an opening with a heavy undercut, a raised threshold, or thick new flooring, the rod length has to be reset so the bolt still fully engages, and the same applies at the head strike. Check the floor condition before the device goes on the door, not after.
8) The doors are narrow stile aluminum storefront - what surface vertical rod device fits instead of the Von Duprin 9827/9927?
The Von Duprin 9827/9927 is a wide stile push pad device, so the mechanism case needs stile width the typical aluminum storefront door does not have. The narrow stile surface vertical rod peers are the Corbin Russwin ED4400, Grade 1 narrow stile at 36 inches for 1-3/4 inch doors, exit only and accepts trim; the Falcon 19-V-EO, Grade 1 narrow stile 36 inch exit only for 1-3/4 inch doors; the Falcon 24-V-EO, Grade 1 narrow stile 36 inch exit only for 1-3/4 inch doors; the TownSteel ED3727, Grade 1 narrow stile at 36 by 84 inches; and the Adams Rite 8200, a Grade 1 narrow stile life-safety device at 30 inches. Measure the lock stile face before committing either way.
9) What is the closest cross-brand equivalent to the Von Duprin 9827/9927 surface vertical rod exit device?
The Von Duprin 9827/9927 is a Grade 1, wide stile, 36 inch surface vertical rod push pad device for 1-3/4 inch doors. The nearest peers on the same three points are the Corbin Russwin ED5400, a Grade 1 wide stile 36 inch surface vertical rod device for 1-3/4 inch doors that is furnished exit only and accepts trim; the Sargent 3727, a Grade 1 wide stile surface vertical rod device with a standard push bar, exit only; and the TownSteel ED8927, a Grade 1 wide stile 36 by 84 inch surface vertical rod device. All three latch to the frame head and sill the same way the 9827/9927 does, so the swap decision comes down to trim family, strike locations and finish rather than device type.
10) Which surface vertical rod exit device do I use on a fire-rated opening if I am specifying against the Von Duprin 9827/9927?
Von Duprin builds the 98/99 Series fire configuration by adding the -F suffix to the device number, and the fire-rated build is the one certified to ANSI/UL 10C and CAN/ULC-S104. If the label on the door has to be matched from another manufacturer, the fire-rated peers are the Adams Rite 3100, a Grade 1 wide stile fire-rated surface vertical rod device for 1-3/4 inch doors; the Sargent 2727, a Grade 1 fire-rated reversible surface vertical rod device with wide stile design, exit only; the TownSteel EF9727, a Grade 1 heavy duty wide stile fire-rated device at 36 by 84 inches that is wood door compatible; and the Arrow S1150, a fire-rated exit only device that fits narrow or wide stile at 1-3/4 inch. Fire openings also rule out dogging, so confirm the device is ordered without hex key dogging.
11) I need outside lever trim on a vertical rod exit device - which options take trim and which are exit only?
The Von Duprin 9827/9927 is field selectable for EO, DT and NL, and for thumbpiece, knob or lever trim the NL drive screw is removed from the device, so one device covers exit only through lever trim. Among the peers, the Corbin Russwin ED5400 and ED4400 are listed exit only and accept trim, and the Corbin Russwin ED7400 accepts operator trim. The Falcon 20 Series, Falcon 25-V-EO, Falcon 19-V-EO and Falcon 24-V-EO, the Arrow 3700 and the Arrow S1150 are listed as exit only devices. If the opening needs keyed entry from the pull side, order a device whose function line covers trim rather than adding trim to an exit only device later.
12) Is the Sargent 12-8710 a drop-in replacement for a Von Duprin 9827/9927?
No, and the function line is why. The Sargent 12-8710 is a Grade 1 fire-rated wide stile surface vertical rod device in the 8700 Series listed with a dummy function, so it is ordered for openings that need the look and push of the device without the active latching function behind it. The Von Duprin 9827/9927 is field selectable for exit only, dummy trim and night latch, with thumbpiece, knob or lever available by removing the NL drive screw. If the opening is an egress door that has to latch, match the function code first; the wide stile format and Grade 1 rating the two share does not carry the function with it.
13) What is the difference between the Von Duprin 9827 and the 9927?
Case appearance. The 9827 has a smooth mechanism case and the 9927 has a grooved one. Everything else about the device is the same, so pick whichever matches the devices already hanging in the building. Both are offered in the same 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.
14) Does the 9827/9927 dog down so the doors stay push-pull during the day?
Hex key dogging is standard on the 9827/9927, so the push pad can be held depressed with a hex key and the door works as push-pull through business hours, then locked back down at close. For a facility that wants to see the state of the device without walking up to it, the CDSI and HDSI security dogging indicators show device status at a glance, cylinder dogging and hex dogging versions respectively. On a fire-rated -F device none of this applies, since a fire device is never dogged.
15) Can a Von Duprin 9827/9927 be tied into a card reader or access control system?
Yes, and there is more than one way in. QEL is electronic latch retraction with limited operational noise, which lets the latches be pulled back from a reader or a scheduled unlock. For monitoring, RX is a request-to-exit switch and LX is a latchbolt monitor, both of which report device state back to the access control panel. If the opening needs delayed egress, the CX CHEXIT option meets NFPA and IBC delayed egress requirements: the door stays secure for 15 seconds after a request to exit while a nuisance alarm sounds.
16) Does the Von Duprin 98/99 exit device meet the 5 pound ADA operating force requirement?
That is the AX option. AX is the accessible version of the 98/99 device, certified to the 5 lb force requirement in the 2010 Americans with Disabilities Act (Chapter 404.2.7) and the 2013 California Building Code (Chapter 11B-309.4). If the opening is on an accessible route and the spec calls out maximum operating force, specify AX when you order rather than trying to adjust a standard device into compliance.
17) Does the Von Duprin 9827/9927 come with mounting hardware, and can it go on a wood door?
Fasteners are included, covering wood or metal doors 1-3/4 inch and 2-1/4 inch thick, so a wood door is a normal application for this device and you are not sourcing screws separately. The device itself is specified for 1-3/4 inch doors. On a wood door, confirm the leaf can take the through-bolting where the center case lands before you drill.
18) We already have Von Duprin 98/99 devices in the building. Can we upgrade them instead of replacing them?
A good deal can be added to devices already on the doors. Retrofit options include CDSI and HDSI security dogging indicators for at-a-glance status, QEL quiet electronic latch retraction, and the electronic switches RX (request to exit) and LX (latchbolt monitoring) for tying into access control or running standalone. Some things do require a new device rather than a kit: AX for the 5 lb accessible force requirement, CX CHEXIT delayed egress, and XP, the two-piece latchbolt design offered for both 98/99 panic and fire applications.
19) Carts and gurneys keep hitting the bottom rod - what are my options besides the Von Duprin 9827/9927?
Two different approaches. The Von Duprin 9827/9927 is supported by vertical rod and latch guards that protect the bottom rod from impacts by carts or gurneys passing through the opening, so the bottom latch stays in service on a hospital or warehouse door. The other approach is a device furnished without the bottom rod at all: the Orca OED56 is a 36 inch standard duty vertical rod device listed less bottom rod, exit only, non-handed, in an aluminum finish. Dropping the bottom rod removes the sill latch point, so the top latch and strike carry the opening and the fire label requirements have to be checked before that route is taken.
20) Is there a lighter-duty surface vertical rod exit device than the Von Duprin 9827/9927 for a low-traffic back door?
The Von Duprin 9827/9927 is certified Grade 1 to ANSI/BHMA A156.3 2014 and is built for high use in schools, hospitals and government facilities. Where the opening does not call for that, the Grade 2 peers are the Dexter ED2000 Series surface vertical rod panic device and the TownSteel TS5100, a Grade 2 wide stile device at 36 by 84 inches. The Design Hardware 2000V is listed as a standard duty surface vertical rod device at 33 inches, alongside the 1000V heavy duty. Grade 2 devices are tested to a lower cycle and strength count than Grade 1, so match the grade to what the door schedule or the facility standard calls for.
21) The door is narrower than 36 inches - which surface vertical rod exit devices come in shorter lengths?
The Von Duprin 9827/9927 in the 3-foot build is a 36 inch device. For shorter openings, the Design Hardware 1000V heavy duty and 2000V standard duty surface vertical rod devices are listed at 33 inches, and the Adams Rite 3100 fire-rated Grade 1 wide stile, the Adams Rite 8100 Grade 1 wide stile life-safety, the Adams Rite 8200 Grade 1 narrow stile and the Arrow 3700 Grade 1 wide stile pushpad are listed at 30 inches. Device length has to leave room at the hinge and lock stiles, so size to the actual door width rather than the nominal opening.
22) I have not confirmed the handing yet - which surface vertical rod exit devices are non-handed or reversible?
The Von Duprin 9827/9927 is non-handed except when SD special dogging, SS signal switch or WS tornado and hurricane options are specified, in which case handing has to be called out on the order. Among the peers, the BEST Precision 5201 at 36 inches and the Sargent 2727 Grade 1 fire-rated wide stile device are listed as reversible, and the Orca OED56 at 36 inches is listed non-handed. Note that the trim is a separate question from the device: night latch and lever trims are ordered LHR or RHR even where the device itself is non-handed.
23) How far does the Von Duprin 9827/9927 project off the face of the door?
Projection is 3-13/16 inches, and the center case measures 8 x 2-3/4 x 2-3/8 inches. That projection is what you check against a door that swings back against a wall, a tight vestibule, or a pair where the two push pads have to pass each other, and it is also what decides whether a wall stop or hold-open catches the device instead of the door.
24) What other Grade 1 surface vertical rod devices should I look at alongside the Von Duprin 9827/9927 for a wide stile hollow metal door?
The Von Duprin 9827/9927 is Grade 1 and wide stile at 36 inches. Beyond the direct Corbin Russwin and Sargent equivalents, the wide stile Grade 1 field includes the Falcon 20 Series at 36 inches for 1-3/4 inch doors, exit only; the Falcon 25-V-EO at 3 feet, wide stile exit only for 1-3/4 inch doors; the Adams Rite 8100, a Grade 1 wide stile life-safety device; the Dexter ED1000 and ED1500 Series Grade 1 surface vertical rod devices; and the BEST Precision 2201, a 36 inch wide stile device in the 2200 Series. Sorting between them usually comes down to trim family and whether the facility already standardizes on one manufacturer's keying and parts.
