Von Duprin 9947EO-F 4 US26 – Frequently Asked Questions

1) Do I have to specify a hand when ordering the Von Duprin 9947F?
The device itself is non-handed, so it goes on either hand of door. Handing still gets specified on the order (RHR or LHR) because trim and certain options follow the hand, and the description notes the non-handed claim does not hold when SD special dogging or SS signal switch is specified. If you are adding SS, get the hand right.
2) Is the 9947F fire rated, and can I dog it open?
Fire rated, listed to ANSI/UL 10C and CAN/ULC-S104, and it ships less dogging. That is the point: fire rated exit devices cannot be mechanically dogged, because the latches have to stay projected to keep the door latched under fire conditions. If you need a device you can hold open during business hours, you need a non-fire rated device with hex or cylinder dogging.
3) Can I use a concealed vertical rod device on a pair of doors with no mullion?
Yes, that is what a CVR is for. The 9947F latches top and bottom into the frame head and the threshold, so a pair of doors works without a center mullion. The top latch throws 3/4 inch and the bottom bolt is 5/8 inch. The tradeoff versus a rim device with a removable mullion is that the rods and latches are inside the door, so the door has to be prepped for them, and floor conditions matter at the bottom strike.
4) What is LBR on the Von Duprin 9947F order, and when do I need LBR-AFL?
LBR is less bottom rod, ordered when you want to drop the bottom latch and rod, usually because of carpet, uneven floor, or a trip hazard at the threshold. On a fire rated pair you specify LBR on the first leaf and LBR-AFL on the second leaf, which adds the auxiliary fire pin needed to keep the fire rating on the inactive leaf. Both are order options on the 9947F.
5) Does the 9947F meet the 5 lb ADA opening force requirement?
Only if you order it with the AX option. AX is the accessible device configuration, certified to the 5 lb force requirement under 2010 ADA Chapters 404.2.7 and 309, and 2013 California Building Code 11B-309.4. AX is a yes or no selection when you configure the device, so on an ADA-scoped opening you have to pick it up front.
6) Is the Von Duprin 9947F Grade 1, and what standards does it carry for a school or hospital spec?
Certified to ANSI/BHMA A156.3 2014 Grade 1, the top grade for exit devices, plus ANSI/UL 305 and CAN/ULC-S132 for panic hardware and ANSI/UL 10C and CAN/ULC-S104 for fire. That combination is what an institutional spec on a fire rated egress opening in a school, hospital or government building normally calls for.
7) My door is an aluminum narrow stile storefront - can I use the Von Duprin 9947F on it?
No. The 9947F is a wide stile device built for metal doors 1-3/4 inch thick, and a wide stile push pad case will not fit a narrow aluminum stile. For narrow stile aluminum openings, the Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod device specifically for aluminum doors. Other narrow stile concealed vertical rod options include the Corbin Russwin ED4800 Grade 1 for 1-3/4 inch doors, the Falcon 1690EO, and the Falcon 1990EO.
8) The opening is not fire rated - is there a simpler concealed vertical rod device than the Von Duprin 9947F?
The 9947F carries a fire rating, and fire-rated devices ship less dogging, so the push bar cannot be held retracted. If the opening does not require a fire rating, the Adams Rite 8500 Series is a Grade 1 wide stile concealed vertical rod device for hollow metal doors listed as non-fire-rated, and the DORMA 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device also listed as non-fire-rated, with a door thickness range of 1-3/4 inch to 2-1/4 inch. Either covers a non-rated metal opening in the same wide stile format.
9) What is the closest cross-brand equivalent to the Von Duprin 9947F concealed vertical rod exit device for a fire-rated hollow metal opening?
The Von Duprin 9947F is a Grade 1, fire-rated, wide stile concealed vertical rod device for metal doors. The closest cross-brand matches on those same attributes are the Adams Rite 3600 Series and the Adams Rite 3900 Series, both fire-rated Grade 1 wide stile concealed vertical rod devices for hollow metal doors, and the Sargent 12-MD8613, a fire-rated Grade 1 wide stile concealed vertical rod device in the 8600 Series. All three cover the same basic opening type: a fire-rated metal door needing concealed top and bottom latching with a wide stile push pad.
10) I need dogging on a concealed vertical rod device - what should I look at besides the Von Duprin 9947F?
The 9947F-4ft is a less dogging device, which is standard for fire-rated exit hardware. If the opening does not require a fire rating and you want mechanical dogging, the Sargent MD8613F-LTRIM is a Grade 1 heavy duty 80 Series concealed vertical rod device for 36 by 84 inch metal doors listed with hex dogging. Confirm your opening's fire requirement before swapping, since dogging a rated door is not permitted.
11) What outside trim options can I get with a Von Duprin 9947 series device?
Fifteen trim functions, from exit only with no outside trim up through night latch, knob, lever, thumbturn, thumbpiece, blank escutcheon, key capture lever, and dummy trim. Classroom-style control comes from the trim, not the device, so pick the function first: NL for a key-to-retract night latch, L or K for always-live lever or knob, EO where you want no outside operation at all. If you choose an L trim you also pick the lever design, 01 through 18, with 06 as the default.
12) Can I get the 9947F with electric latch retraction for access control?
Yes. EL electric latch retraction, QEL quiet electric latch retraction, and PN pneumatic are all available. Pair that with a switch option if you need signalling back to the panel: RX request to exit, LX latchbolt monitor, LX-RX combined, RX-2 double RX, RX-LC low current, WP-RX waterproof, or SS signal switch. Alarm kits ALK, RX-ALK and LXRX-ALK are also on the option list. On a fire rated device the latches must relatch on alarm, so the electric latch retraction is the code-correct way to get a hold-open-like function instead of dogging.
13) What is the difference between the 9947F grooved case and the 9847F?
Same device mechanically, different look. The 99 series uses the grooved mechanism case with a wide stile push pad, the 98 series is the smooth case. Both are in the 98/99 Series family and share the Grade 1 rating, the 3/4 inch latch throw and the same option list. Pick on appearance and on what is already hanging in the building if you are matching other openings.
14) Are fasteners included with the Von Duprin 9947F, or do I need to order them?
Fasteners come in the box, covering wood or metal doors 1-3/4 inch and 2-1/4 inch thick. What is not in the box is the outside trim and cylinder, those are ordered separately by trim function, and any strike work at the head and threshold that the opening needs.
15) Does the 9947F support delayed egress?
Yes, through the CX CHEXIT upgrade. Configured that way the door stays secure for 15 seconds after a request to exit while a nuisance alarm sounds, which meets NFPA and IBC delayed egress requirements. Confirm your local authority permits delayed egress on that occupancy before speccing it.
16) I only need exit-only with no outside trim - what are the alternatives to a trimmed Von Duprin 9947F?
The 9947F can be ordered in an EO exit only trim function, so you can stay in the 98/99 Series without outside trim. If you are looking at other brands for a straight exit-only concealed vertical rod device, the CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device listed as exit only, matching the 48 inch size of the 9947F-4ft. The BEST Precision 2601 Series is another exit-only, non-handed concealed vertical rod device, though in a narrow stile.
17) What is the difference between the Von Duprin 9947F and a crossbar concealed vertical rod device?
The 9947F uses a push pad style actuator on a wide stile grooved case. The Corbin Russwin ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device for 1-3/4 inch doors that accepts operator trim - a horizontal crossbar rather than a push pad, and a narrow stile case. If your facility standard is push pads, stay with the 9947F or another wide stile push pad device such as the Corbin Russwin ED5800.
18) Can a CRL Jackson 1285 replace a Von Duprin 9947F on a fire-rated door?
The CRL Jackson 1285 is a push pad concealed vertical rod panic exit device listed as exit only and fitting narrow, medium or wide stiles. It is a panic device by listing, not a fire-rated device, and it is exit only, so it will not carry outside trim. The 9947F is fire rated and can be ordered with knob, lever, thumbturn, thumbpiece or night latch trim. For a rated opening that needs outside trim, stay with the 9947F or another fire-rated wide stile device such as the Adams Rite 3900 Series.
19) My doors vary between 1-3/4 inch and 2-1/4 inch thick - is the Von Duprin 9947F still the right choice?
The 9947F is specified for 1-3/4 inch metal doors and ships with fasteners for doors 1-3/4 inch and 2-1/4 inch thick. If you want a device whose stated thickness range spans 1-3/4 inch to 2-1/4 inch, the DORMA 9100 Series wide stile pushpad and the DORMA 9600BB narrow stile pushpad both list that range, though both are listed as non-fire-rated, so they do not cover a rated opening the way the 9947F does.
20) Can I get the Von Duprin 9947F in a finish to match the rest of my building's door 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 standards.
21) What push bar options are there for a low vision or high abuse installation?
Beyond the standard bar you can order BR braille pushbar, KN knurled bar, RSS emergency exit push bar, or SG safety glow pushbar. Knurled bar is the tactile warning surface used on doors leading to hazardous areas, and safety glow helps in a power-down egress path. QM quiet mechanical is a separate yes or no option if noise in a corridor or a dorm is a concern.
22) Are there Grade 1 concealed vertical rod alternatives to the Von Duprin 9947F that also accept outside trim?
Yes. The 9947F accepts a wide range of outside trim including lever, knob, thumbturn and night latch. Among other Grade 1 concealed vertical rod devices for 1-3/4 inch doors that are listed as exit only and accepting trim, the Corbin Russwin ED5800 is the wide stile option and the Corbin Russwin ED4800 is the narrow stile option. Match the stile type to your door leaf before ordering.
23) Is the BEST Precision 2801 a wide stile match for the Von Duprin 9947F?
The BEST Precision 2801 Series is a wide stile concealed vertical rod exit device, so it shares the wide stile push-style format of the 9947F. The 9947F additionally carries a Grade 1 certification and a fire rating with a 3/4 inch latch throw. If the opening is rated, verify the 2801 configuration you are quoting carries the fire listing your inspector requires.
