Von Duprin 7847EO-F 4 626 – Frequently Asked Questions

1) Will a 7847F fit a 1-3/8 inch door?
No. The 7847F is built for 1-3/4 inch doors only, which is the standard commercial thickness. There is no thicker or thinner range on this device. If your openings are 1-3/4 to 2-1/4 inches, the DORMA 9100 Series wide stile pushpad CVR covers that thickness range.
2) Is the Von Duprin 7847F approved for a fire rated door assembly?
Yes. The 7847F is a fire rated device, certified to ANSI/UL 10C and CAN/ULC-S104, and it also carries ANSI/BHMA A156.3-2014 Grade 1 along with ANSI/UL 305 and CAN/ULC-S132. On a fire door you must order it less dogging, since a fire rated exit device cannot be held dogged down.
3) What strikes do I need with the Von Duprin 7847F?
The 7847F uses a 338 strike at the top and a 385A strike at the bottom. The latch throw is 3/4 inch, so both the head and threshold prep have to be set for those specific strikes rather than reused from an older device with different keepers.
4) What trim functions can I get on the 7847, and do I pick a lever style separately?
Trim functions run from EO exit only and DT dummy trim through NL night latch, NL-OP night latch with optional pull, L lever, L-BE lever with blank escutcheon, L-DT, L-NL, T-BE thumbturn with blank escutcheon, and TL thumbturn that unlocks. If you choose an L function you also pick the lever design: 06 is the default, with 01, 02, 03, 05, 07, 12, 16, 17 and 18 also available. Non-lever functions take no lever selection.
5) Can I get electric latch retraction and exit monitoring on the 7847?
Yes. Latch retraction options include QEL quiet electric latch retraction, HD-QEL with hex dogging (panic only), and QELX and HD-QELX for AX accessible devices. On the switch side you can specify RX request to exit, LX latchbolt monitor, LX-RX combined, RX2 double RX switch, WP-RX waterproof RX, or the ALK alarm exit kit in less switch, RX-ALK, and LXRX-ALK versions. Note HD-QEL variants are panic only, so they are not the path on a fire rated opening.
6) Can I use the Von Duprin 7847F on a wood door?
No - the 7847F is not wood door compatible. For a wood door, the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod exit device specified for wood doors. If your opening is hollow metal, the Adams Rite 3600 Series and 8500 Series are concealed vertical rod devices for hollow metal doors.
7) The 7847F will not fit my narrow stile aluminum door - what concealed vertical rod device should I use instead?
The 7847F is built for wide stile doors, so it is the wrong platform for a narrow stile aluminum opening. Narrow stile concealed vertical rod options include the Adams Rite 8600 Series for aluminum doors, the Corbin Russwin ED4800, a Grade 1 narrow stile CVR for 1-3/4 inch doors, the DORMA 9600BB narrow stile pushpad device, and the Falcon 1690EO and 1990EO narrow stile exit-only devices for 1-3/4 inch doors.
8) What is the closest fire-rated wide stile concealed vertical rod alternative to the Von Duprin 7847F?
The Von Duprin 7847F is a Grade 1, fire-rated concealed vertical rod exit device for wide stile doors. The closest fire-rated wide stile equivalents are the Adams Rite 3600 Series and Adams Rite 3900 Series, both Grade 1 fire-rated concealed vertical rod devices for wide stile openings, and the Sargent 12-MD8613, a Grade 1 fire-rated wide stile concealed vertical rod device in classroom function. If your opening requires a fire-rated assembly, any of these keeps you within a fire-rated CVR device rather than a panic-only one.
9) My door is thicker than 1-3/4 inch - which concealed vertical rod device should I look at instead of the 7847F?
The 7847F is specified for a 1-3/4 inch door thickness. For a thicker door, the DORMA 9100 Series wide stile pushpad concealed vertical rod device and the DORMA 9600BB narrow stile version are both listed for 1-3/4 inch to 2-1/4 inch doors, so pick by stile type at your opening.
10) Why choose a concealed vertical rod exit device instead of a rim device with a mullion?
A concealed vertical rod device latches at the head and the sill with the rods hidden inside the door, so a pair of doors is secured top and bottom with no center mullion and nothing exposed on the door face. A rim device plus removable mullion is simpler to install and service but puts a post in the middle of the opening and leaves hardware on the surface. Concealed rod also requires factory or shop door prep, which a rim device does not.
11) Can I order the 7847F without the bottom rod?
Yes, less bottom rod is an orderable option on the 7847. Crews commonly specify it where a bottom latch would foul an uneven floor or a threshold, and it removes the bottom strike from the picture. Where you keep the bottom rod, the 385A bottom strike applies.
12) How high off the floor does the 7847 push pad mount, and how far does it stick out?
Device centerline is 39-13/16 inches from finished floor and the projection off the door face is 3-13/16 inches. Use the projection when checking clearance against door swing, adjacent walls, or a pair of doors in a tight vestibule.
13) What dogging choices are there on the Von Duprin 78 Series 7847?
Three: hex key dogging (the default), CD cylinder dogging if you want to dog and undog with a key rather than an allen wrench, or LD less dogging. Hex key dogging holds the latch retracted through busy hours, but on a fire rated opening you need LD.
14) Is the 7847F heavy duty enough for a warehouse or school exterior door?
It is a commercial Grade 1 device under ANSI/BHMA A156.3-2014, which is the top performance tier for exit devices, and the 78 Series is built for warehouse, industrial, office, retail, multifamily and institutional traffic. For high-use periods you can dog the push pad down with the hex key so the latch stays retracted, though that option is off the table on a fire rated leaf.
15) Does the 7847F come with an accessible-device option for reduced operating force?
Yes, AX accessible device is a required selection on the 7847, so you choose it as yes or no when ordering. If you go AX and also want electric latch retraction, the matching retraction options are QELX and HD-QELX rather than the standard QEL.
16) Which wide stile concealed vertical rod devices compete with the Von Duprin 78 Series in Grade 1 commercial work?
The Von Duprin 7847F is a Grade 1 wide stile concealed vertical rod device with a 3/4 inch latch throw for 1-3/4 inch doors. Directly comparable Grade 1 wide stile CVR platforms include the Corbin Russwin ED5800 for 1-3/4 inch doors, the DORMA 9100 Series heavy duty pushpad for 1-3/4 inch to 2-1/4 inch doors, the Adams Rite 8500 Series, and the BEST Precision 2801 Series wide stile concealed vertical rod device.
17) I only need exit-only push pad hardware at 48 inches - what compares to the 7847F?
The 7847F is a 48 inch push pad concealed vertical rod device offered in EO exit-only among its trim functions, alongside lever and night latch options. If exit-only is all the opening needs, 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, and the CRL Jackson 1285 is a push pad concealed vertical rod panic exit in exit-only function that suits narrow, medium or wide stiles.
18) What wide stile concealed vertical rod device accepts lever trim like the 7847F L function?
The 7847F offers lever trim functions including L, L-BE, L-DT and L-NL. Among wide stile concealed vertical rod alternatives, the Corbin Russwin ED5800 is a Grade 1 wide stile CVR for 1-3/4 inch doors in exit only function that accepts trim, and the Sargent MD8613F-LTRIM is a Grade 1 heavy duty concealed vertical rod device supplied with lever trim and hex dogging for 36 inch by 84 inch metal doors.
19) What looks like a substitute for the 7847F but will not work as an egress device?
The Falcon 1491DT is a narrow stile concealed vertical rod unit in dummy function with a 9970 pull for 1-3/4 inch doors - it has no latching or egress function and is used on the inactive or pull side, so it does not replace the 7847F, which is a Grade 1 fire-rated latching exit device. The BEST Precision 2601 is exit only and narrow stile, so it also will not drop into a wide stile opening that needs lever or night latch trim.
20) What finishes does the Von Duprin 7847 come in for matching the rest of a building?
Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. 628 aluminum and 626 satin chrome are the usual picks when standardizing across a commercial stairwell or exterior set.
21) Is a crossbar concealed vertical rod device an alternative to the 7847F push pad?
They are different operating styles. The 7847F uses a push pad. 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, so it changes both the actuator style and the stile type. Specify it only where a crossbar appearance is wanted on a narrow stile opening.
