Von Duprin 9927EO-F 4 US26D – Frequently Asked Questions

1) Can the 9927F be used on a fire rated door assembly?

Yes. The 9927F carries the F for fire rated and is listed to ANSI/UL 10C and CAN/ULC-S104, plus ANSI/UL 305 and CAN/ULC-S132 for panic. It's also certified to ANSI/BHMA A156.3 2014 Grade 1. That combination is what an inspector wants to see on a fire door in a school, hospital, or government building. One consequence to plan for: fire rated devices come less dogging, so this one cannot be held retracted mechanically.

2) Why can't I dog down the push bar on the 9927F, and how do I hold the door unlatched during business hours?

Less dogging is not an omission, it's a fire code consequence: a fire rated exit device has to latch every time the door closes, so mechanical dogging is not offered on the 9927F. If you need the latches held back during open hours, the electric route is the one available here. Order it with QEL quiet electric latch retraction, EL electric latch retraction, or PN pneumatic. Those retract the latches on a signal and drop them back on fire alarm, which is what keeps the assembly compliant.

3) How much does the 9927F stick out from the door, and will it clear my frame and adjacent wall?

Projection is 3-13/16 inches off the door face, with a center case of 8 x 2-3/4 x 2-3/8 inches. That's the number to check against a door that swings back against a wall or into a tight vestibule, and against any wall stop or overhead holder you're mounting. It's a wide stile device, so you also need enough flat stile face to land the 8 inch case.

4) Can a surface vertical rod exit device secure a pair of doors without a mullion?

That's exactly what it's for. The 9927F latches at the head and at the threshold rather than into a strike on the jamb, so a pair of doors can be secured with no center mullion and the full opening stays clear when both leaves are open. If you'd rather keep a mullion and a simpler single latch point, a rim device is the alternative type. Where the bottom rod is a hazard, carts and gurneys in a hospital corridor being the usual case, order LBR less bottom rod, or add a vertical rod and latch guard to protect it.

5) What outside trim can I get with the Von Duprin 9927F, and what do I order for a classroom door?

Fifteen trim functions are offered, covering exit only with no outside operator, night latch and night latch with optional pull, knob and lever in plain, blank escutcheon, and night latch versions, lever with key capture, thumbturn, thumbpiece, and dummy trim. For a classroom or office where staff need key access from the corridor, night latch or a lever night latch is the usual pick. If you choose an L lever function you also pick the lever design: 06 is the default, with 01, 02, 03, 05, 07, 17, and 18 also available. Exit only means the door is push-to-exit with no way in from outside.

6) Does the Von Duprin 9927F meet ADA opening force requirements?

Only with the AX option specified. AX is the accessible device version, ADA certified at 5 lb force per 2010 ADA chapters 404.2.7 and 30934 and 2013 California Building Code chapter 11B-309.4. It's a yes or no choice at order time on the 9927F, so if the opening is on an accessible route, select AX rather than assuming the standard device meets it.

7) Will the 9927F latch into my existing top and bottom strikes?

Latch throw is 3/4 inch, which is what determines engagement into the head and floor strikes. If you're replacing another surface vertical rod device, measure the existing strike pockets against that 3/4 inch throw, and confirm the door prep. The 9927F mounts to hollow metal doors with 86 or 161 cutouts at 1-3/4 inch thickness. Top and bottom latch kits are stocked separately as the 050492 top latch kit and 050493 and 050495 bottom latch kits for 33/35 and 98/99 Series devices.

8) What's the difference between a narrow stile and a wide stile surface vertical rod exit device?

Stile type is about how much flat face the door gives you next to the glass. The 9927F is wide stile with an 8 x 2-3/4 x 2-3/8 inch case, which suits hollow metal and full flush doors. On an aluminum storefront leaf with a slim stile, that case has nowhere to land, and you want a narrow stile device instead: the Corbin Russwin ED4400 or the Adams Rite 8200 Series are narrow stile surface vertical rod devices, though neither is fire rated. For a narrow stile opening that does need a fire rating, the Arrow S1150 is fire rated and listed for narrow or wide stile.

9) What is the closest cross-brand equivalent to the Von Duprin 9927F 48-inch surface vertical rod exit device for a fire-rated opening?

The Von Duprin 9927F-4ft is a fire-rated, Grade 1, wide stile surface vertical rod device. The closest cross-brand match on those same three attributes is the TownSteel 9700 Series EF9727, a fire-rated Grade 1 heavy-duty wide stile surface vertical rod device. The Sargent 12-8710 is also a fire-rated Grade 1 wide stile surface vertical rod device, and the Adams Rite 3100 Series is fire-rated Grade 1 wide stile for 1-3/4 inch doors, the same door thickness the 9927F is designed for. One difference that matters on a wood opening: the TownSteel EF9727 is listed as wood door compatible, while the 9927F is not.

10) Is the Sargent 2727 or the Corbin Russwin ED5400 a valid substitute for the Von Duprin 9927F on a fire door?

The Sargent 2727 is a Grade 1 wide stile surface vertical rod device that is fire rated, so it addresses the same fire-door requirement the 9927F-4ft does; it is an exit only function, so a trim-operated opening needs a different function. The Corbin Russwin ED5400 is a Grade 1 wide stile surface vertical rod device for 1-3/4 inch doors, but it is not fire rated, so it is not a substitute on a fire-door assembly even though the stile type and grade line up. The same applies to the Adams Rite 8100 and the Falcon 20 Series, both Grade 1 wide stile devices that are not fire rated.

11) Which surface vertical rod exit devices can be used instead of the Von Duprin 9927F on a wood door?

The Von Duprin 9927F-4ft is not wood door compatible; its included fasteners are for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. When the opening is a wood door, the TownSteel EF9727 is listed as wood door compatible and is a fire-rated Grade 1 wide stile surface vertical rod device. If the opening is not fire rated, the TownSteel ED8927 is a Grade 1 wide stile wood door compatible surface vertical rod device, and the TownSteel ED3727 is the narrow stile version of the same wood-compatible approach.

12) What looks like a substitute for the Von Duprin 9927F but will not actually work as one?

Two traps. The Sargent 12-8710 is a fire-rated Grade 1 wide stile surface vertical rod device, which reads as a straight match, but its function is dummy - it does not latch or release, so it cannot replace an operating 9927F-4ft. The Corbin Russwin ED7400 is a Grade 1 surface vertical rod device for 1-3/4 inch doors, but it is a narrow stile crossbar device, so both the stile requirement and the actuator differ from the 9927F push pad. The 9927F-4ft is a push pad device in a wide stile grooved case.

13) Do I need to specify a hand for the Von Duprin 9927F?

The device itself is non-handed, so the mechanism doesn't care which way the door swings. Handing still gets specified on the order, RHR or LHR, because trim and certain options key off it. The description also notes the device is non-handed except when SD, SS, or WS options are used, so if you're adding a signal switch that exception applies.

14) What is LBR on a vertical rod exit device and should I order it?

LBR means less bottom rod: the device ships without the lower rod and bottom latch, latching only at the head. Buyers specify it where the bottom rod would get beaten up by carts or gurneys, or where floor conditions make a bottom strike impractical. The 9927F is offered both ways. Understand the trade before you pick, since dropping the bottom latch changes how the leaf is held at the floor, and on a fire rated opening the LBR configuration has to match what the door assembly's listing permits.

15) Which Von Duprin 9927F options do I need for access control tie-in?

For monitoring and control the switch options are RX request to exit, LX latchbolt monitor, LX-RX combined, WP-RX waterproof, RX-LC low current, RX-2 double request to exit, SS signal switch, and the ALK alarm kits in less switch, RX, and LX plus RX versions. For remote unlocking, add EL, QEL, or PN latch retraction. RX tells the panel someone pushed the bar, LX tells it the latch is actually thrown, and integrators commonly run both. Existing 98/99 devices can be converted later with the Von Duprin 040061 QEL modular conversion kit for 3 foot and 4 foot devices, or the 050251 request to exit switch.

16) How do I quiet down a noisy exit device in a hospital or library corridor?

Two options on the 9927F address noise. QM quiet mechanical is a yes or no selection on the device itself. If you're also electrifying it, QEL is the quiet version of electric latch retraction, as against standard EL. Both are chosen at order time and neither is a field add without the conversion kit, so decide before you place the order if the opening is anywhere sound matters.

17) What other fire rated Grade 1 surface vertical rod exit devices could I use instead of the Von Duprin 9927F?

Three in the same class. The Sargent 2727 is a reversible Grade 1 fire rated wide stile device, exit only. The TownSteel EF9727 from the 9700 Series is a fire rated Grade 1 heavy duty wide stile device and is wood door compatible, which the Von Duprin is not. The Adams Rite 3100 Series is a fire rated Grade 1 wide stile device for 1-3/4 inch doors. Where the Von Duprin separates itself is the depth of field options, AX accessible, QEL, the RX and LX switch family, and the ALK alarm kits.

18) What is a simpler exit only surface vertical rod device to use where the Von Duprin 9927F trim options are not needed?

The 9927F-4ft is offered with trim functions ranging from exit only through lever, knob, night latch, thumbturn and thumbpiece. Where the opening only needs egress and no outside operation, the Falcon 25-V-EO is a Grade 1 wide stile surface vertical rod device in an exit only function for 1-3/4 inch doors, the Arrow 3700 Series is a Grade 1 wide stile pushpad exit only device, and the Sargent 3727 is a Grade 1 wide stile exit only device with a standard push bar. The Orca OED56 is a standard duty exit only vertical rod device supplied less bottom rod. None of these four are fire rated, so they suit a non-rated opening.

19) What is the difference between the Von Duprin 9927F and a Grade 2 surface vertical rod exit device like the TownSteel TS5100 or Dexter ED2000?

The 9927F-4ft is certified Grade 1 and fire rated. The TownSteel TS5100 is a Grade 2 heavy duty wide stile surface vertical rod device that is not fire rated, and the Dexter ED2000 is a Grade 2 surface vertical rod panic device that is not fire rated. Grade is the ANSI/BHMA cycle and strength classification, so a Grade 2 device is a different certification level, and neither carries the fire listing a fire-door assembly requires. Within Grade 1 but without a fire rating, the Dexter ED1500 and the BEST Precision 2201 wide stile device are alternatives for non-rated openings.

20) Which heavy duty surface vertical rod exit devices are in the same class as the Von Duprin 9927F for a high traffic school or hospital opening?

The 9927F-4ft is a Grade 1 wide stile device with a 3/4 inch latch throw, built for high use commercial and institutional openings. In the same heavy duty class, the TownSteel EF9727 is a heavy duty Grade 1 fire-rated wide stile device and the Design Hardware 1000V is a heavy duty surface vertical rod device. The Design Hardware 2000V is the standard duty device in that same line, and the Orca OED56 is also standard duty - a lower duty level than the 9927F carries.

21) Can a less bottom rod surface vertical rod device replace the Von Duprin 9927F where carts damage the bottom rod?

The 9927F-4ft is available in an LBR less bottom rod configuration, which removes the bottom rod and latch from the opening. Among other surface vertical rod devices, the Orca OED56 is supplied less bottom rod as a standard duty exit only device in aluminum finish, though it is not fire rated. On a fire-door assembly the LBR configuration and the fire listing have to be specified together, which the fire-rated 9927F-4ft and the fire-rated Grade 1 TownSteel EF9727 both address as fire-rated devices.

22) What finishes does the Von Duprin 9927F come in for matching existing hardware 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 satin chrome and 630 satin stainless are the two that most commonly match an existing fleet of openings. Order the same BHMA number that's on the doors you're matching and the new device will read the same across the building.

23) What push bar styles are available on the 9927F for accessibility or low light egress?

Five bar choices beyond the standard grooved case push pad. BR is a braille pushbar and KN a knurled bar, both giving a tactile cue at the exit. SG is a safety glow pushbar for low light or power loss conditions in a corridor or stairwell. RSS is the emergency exit push bar. Pick the bar when you order, since it's part of the device build rather than a later add.
