Von Duprin 78EO-F 4 626 – Frequently Asked Questions

1) Can I use the 78F on a fire rated door assembly?
Yes, that is what the F suffix means. The Von Duprin 78F is fire rated and certified to ANSI/UL 10C and CAN/ULC-S104. Note that fire rated devices cannot be dogged down open, so the hex key dogging is only usable on non-fire applications. On a true fire door, order the LD (less dogging) option.
2) Which strike do I order with the 78F for a pair of doors?
Strike choice is a required selection. The 299 strike is the one for hollow metal and wood door frames on a single opening. For double door applications, take the 499F strike. Pick this before you order, since the wrong strike means the latch has nothing to catch.
3) Will the 78F fit a narrow stile aluminum storefront door?
No. The 78 Series is a wide stile pushpad device and needs the stile width of a hollow metal or heavy commercial door. For narrow stile aluminum storefront, look at a narrow stile rim device such as the Adams Rite 8800 Series or the Corbin Russwin ED4200.
4) Can the 78F be set up so an access control system retracts the latch?
Yes. The 70 Series platform supports QEL quiet electric latch retraction, and it is offered several ways: plain QEL, HD-QEL with hex dogging (panic only), and QELX or HD-QELX for AX accessible devices. Pair it with an RX request-to-exit or LX latchbolt monitor switch if the access control panel needs door status.
5) What is the difference between a rim device like the 78F and a vertical rod device?
A rim device latches into a strike on the frame or on the mullion, so it suits a single door or a pair with a mullion between them. The 78 Series also comes as 27/SVR surface vertical rod and 47/CVR concealed vertical rod, which latch at the head and threshold instead and are what you want on a pair with no mullion or on double egress openings.
6) Is the 78F ANSI Grade 1, and what standards does it hold for a spec submittal?
Grade 1 under ANSI/BHMA A156.3-2014, plus ANSI/UL 305 and CAN/ULC-S132 for panic hardware and ANSI/UL 10C with CAN/ULC-S104 for fire. That set covers the usual submittal requirements on institutional and government work.
7) Which Grade 1 fire rated rim exit devices work on a wood door, since the 78F does not?
The Von Duprin 78F is listed as not wood door compatible. For a fire rated Grade 1 rim device on wood, the Adams Rite 3700 Series is fire rated, Grade 1, and wood door compatible, though it is a narrow stile device with starwheel interlocking rather than the wide stile pushpad format of the 78F.
8) What is a fire rated 48 inch rim exit device I can use instead of the Von Duprin 78F-4ft?
The Marks USA M9900F-48 is a 48 inch fire rated rim panic exit device supplied exit only with a panic protector end cap, and it is not wood door compatible. The Von Duprin 78F is also fire rated at 48 inches, is Grade 1, and is offered in trim functions from exit only through lever, night latch and dummy trim, so the Marks device covers the exit only opening while the 78F covers openings that need outside trim.
9) My door has a narrow stile - what rim device should I use instead of the Von Duprin 78F?
The 78F is a wide stile device and needs the stile width to suit. For narrow stile aluminum and similar doors, the Falcon 19-R is a Grade 1 narrow stile rim device in exit only for 1-3/4 inch doors, and the Corbin Russwin ED4200 is a Grade 1 narrow stile rim device for 1-3/4 inch doors available exit only or accepting trim. The Sargent 8504 is a narrow stile Grade 1 rim device in night latch function if outside key access is required.
10) Is the Cal-Royal 5500 a direct substitute for the Von Duprin 78F-4ft?
They are both 48 inch wide rim exit devices, but they are not equivalent on the two specs that usually govern the order. The Cal-Royal 5500 is a heavy duty push bar device with a Grade 2 rating and is not fire rated. The Von Duprin 78F is Grade 1 and fire rated, so on a rated assembly or a Grade 1 spec the 5500 will not substitute.
11) How high off the floor does the 78 Series exit device mount?
The device centerline sits at 39-13/16 inches from finished floor, which keeps the pushpad inside the code band for panic hardware. Projection off the door face is 3-13/16 inches, so account for that clearance where the door swings past a wall or a second leaf.
12) What mounting hardware comes with the Von Duprin 78F, and do I need sex bolts?
A screw pack for 1-3/4 inch and 2-1/4 inch thick metal or wood doors ships with the device. If the door construction calls for through-bolting, the 425 SNB sex nut and bolt kit is a separate order.
13) What trim functions can I get on the 78 Series rim device?
Eight trim functions are offered: exit only, night latch, night latch with optional pull, dummy trim, lever, lever with blank escutcheon, lever with dummy trim, and lever with night latch. If you pick an L trim, you also choose the lever style, with the 06 lever as the default and 01, 02, 03, 05, 07, 12, 16, 17 and 18 also available.
14) Does the 3/4 inch latch throw on the 78F work with my existing rim strike?
The 78F latchbolt throws 3/4 inch, which is the standard rim device throw, but Von Duprin rim latches are keyed to their own strike geometry. If you are replacing a different brand, plan on installing the 299 strike (single door) or 499F (pairs) that goes with the device rather than reusing the old one.
15) Do I need cylinder dogging instead of hex key dogging?
Hex key dogging is the default and is fine where only staff hold the door open. CD cylinder dogging lets you dog and undog with a key instead of an allen wrench, which property managers usually prefer on doors the public can reach. LD is less dogging, and that is the one to take on fire rated openings where dogging is not permitted.
16) When should I order the AX accessible version of the 78 Series?
AX is the accessible device option and is selected yes or no at order. If the opening has to meet accessibility requirements for operating force, take AX. Note that the electric latch retraction option changes with it: AX devices use QELX or HD-QELX rather than plain QEL.
17) If the opening is not fire rated, what wide stile 48 inch rim device compares to the Von Duprin 78F-4ft?
For a non-rated opening, the DORMA 9300 Series is a 48 inch wide stile panic rim exit device in exit only, Grade 1 heavy duty, for 1-3/4 inch to 2-1/4 inch doors. The Corbin Russwin ED3200 is a Grade 1 48 inch wide stile crossbar rim device for 1-3/4 inch doors, a crossbar rather than the push pad style of the 78F. The Von Duprin 78F carries the fire rating, so it is the one to keep where the assembly is rated.
18) Von Duprin 78F versus Sargent 8800 fire rated wide stile - what is the difference?
The Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim exit device in dummy function, supplied with RX and motorized electric latch retraction. The Von Duprin 78F is also fire rated Grade 1 wide stile and can be configured with RX, LX, LX-RX and alarm kit switches and with QEL quiet electric latch retraction, plus trim functions from exit only through lever and night latch rather than dummy alone.
19) Is an SDC exit bar an alternative to the Von Duprin 78F?
They solve different problems. The SDC MSB550 is a mechanical switch bar that releases an electromagnetic lock, and the SDC PSB560 SureExit is a pressure sense bar with tri-failsafe technology; both suit narrow or wide stile and neither is fire rated. The Von Duprin 78F is a mechanical latching rim exit device with a 3/4 inch latch throw and a fire rating, so on a rated latched opening the switch bars are not a substitute.
20) I need hex key dogging on a rim device - which products besides the Von Duprin 78F offer it?
The Von Duprin 78F comes with hex key dogging as standard and can also be ordered CD cylinder dogging or LD less dogging. The Design Hardware 1000R is a 33 inch heavy duty rim device with hex key dogging, the 2000R is the 33 inch standard duty wide stile version with hex key dogging, and the Stanley QED200 is a Grade 1 heavy duty narrow stile rim device with hex key dogging. None of those three are fire rated devices on the same basis as the 78F, which carries a fire rating.
21) What finishes does the Von Duprin 78F come in for matching existing hardware?
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. For a building already standardized on 626 satin chrome, that is the common commercial match.
