Von Duprin 5575EO-US3-3 – Frequently Asked Questions

1) Can I use the Von Duprin 5575 on a fire rated door?
No. The 5575 as configured is not fire rated. It is UL listed for accident hazard installations and certified to ANSI/BHMA A156.3 2008 Grade 1, ANSI/UL 305 and CAN/ULC-S132, all of which is panic hardware, not fire exit hardware. Fire rated configurations of the 55 Series are a separate order, built to ANSI/UL 10C and CAN/ULC-S104 with an -F suffix. If the opening is a labeled fire door, order the -F version, or look at a device rated from the start such as the Adams Rite 3300 Series fire rated mortise device.
2) Do I have to order the Von Duprin 5575 handed, or can it be reversed in the field?
Handing is picked at order time, LHR or RHR, but you are not locked in. The 7500 mortise lock inside the 5575 is field reversible without pulling the lock off the door, and the auxiliary deadlocking bolt is non-handed. The faceplate bevel is adjustable too. For a property manager standardizing a building, that means one device can be turned around on site rather than sent back.
3) What outside trim functions can I order with the Von Duprin 5575 mortise exit device?
Six trim choices on the 5575: exit only (EO, no outside trim at all), night latch (NL, key retracts the latch to get in), lever (L), lever with blank escutcheon (L-BE), lever dummy trim (L-DT), and dummy trim (DT). Any of the lever functions needs a lever style called out as well: 06 is the default on L trim, with 03, 07 and 17 also offered. Pick EO where nobody re-enters through that door, NL for a service or back-of-house door a keyholder needs to open.
4) Will the Von Duprin 5575 latch into my existing strike?
Latch throw is 1/2 inch, which is a short mortise latch throw, so the existing strike has to be a mortise strike in the frame with the pocket at the right height for a 7-1/4 x 1-1/4 x 2-1/4 inch case. It is not a substitute for a vertical rod or rim strike. There is also a non-handed auxiliary bolt that deadlocks the latch when the door closes, so the strike prep has to clear that bolt as well as the main latch.
5) I have a wide stile hollow metal or wood door. Is the Von Duprin 5575 still the right device?
It will look and sit wrong. The 5575 is built to the narrow stile profile. For a wide stile wood or hollow metal leaf, the wide stile mortise devices are the match: the Adams Rite 8300 Series for wood and hollow metal, the Falcon 25-M-EO in a 36 inch exit only version for 1-3/4 inch doors, or the Corbin Russwin ED5600AL, which is a 3 hour fire rated Grade 1 mortise device for 1-3/4 inch doors that accepts passage or classroom lever trim. Note the Detex 30 Series wide stile device is not wood door compatible.
6) Which mortise exit device should I use on an aluminum narrow stile storefront door instead of the Von Duprin 5575?
The Von Duprin 5575-3ft is a narrow stile mortise exit device, so it is already in the right family for narrow stile openings, and it carries a 1-3/4 inch door thickness. If the opening is an aluminum narrow stile door, the Adams Rite 8400 Series is a Grade 1 non-fire-rated narrow stile mortise exit device built specifically for aluminum doors. The difference is the operating style: the 5575 is a crossbar device with a 3-3/4 inch projection from the door face, which reads differently on a glass storefront than a flat pushbar profile.
7) What is the closest narrow stile mortise exit device to the Von Duprin 5575 if I need a fire rated opening?
The Von Duprin 5575-3ft in its standard form is not fire rated. For a fire rated mortise exit device, the Adams Rite 3300 Series is a Grade 1 fire rated mortise exit device for wood and hollow metal doors, though it is built for wide stile rather than narrow stile doors. On the Von Duprin side, fire rated configurations to ANSI/UL 10C and CAN/ULC-S104 are ordered by adding the -F suffix to the 5575. If the door is a narrow stile aluminum door and the opening is fire rated, the Adams Rite 3300 will not fit the stile and the -F version of the 5575 is the path.
8) I need a night latch mortise exit device on a narrow stile door. How does the Sargent 8304 compare to the Von Duprin 5575 NL?
Both cover the same opening type. The Von Duprin 5575 offers NL Night Latch as one of its trim functions on a narrow stile Grade 1 mortise device with a field reversible 7500 mortise lock and hex key dogging. The Sargent 8304 is a Grade 1 narrow stile mortise exit device from the 8300 Series supplied in the night latch function specifically. The 5575 arrives as a crossbar device with a 3-3/4 inch projection; if the aesthetic on the rest of the building is crossbar, staying with the 55 Series keeps the openings matched.
9) Can I put the Detex 30 Series on a wood door where I would otherwise use a Von Duprin 5575?
No. The Detex 30 Series Advantex is a Grade 1 wide stile mortise exit device that is not wood door compatible, and it is supplied device only in exit only function. The Von Duprin 5575 accepts wood doors: the screw pack covers 1-1/4 inch and 2-1/4 inch thick metal and wood doors, wood doors require the 589 cover plate, and the 2-1/4 inch door must be specified when ordering. The 5575 also carries lever and night latch trim functions rather than exit only alone.
10) Should I use a mortise exit device or a rim or vertical rod device on my opening?
Go mortise, like the 5575, when the door has a mortise pocket prepped in the lock stile and you want the latching hardware inside the door rather than hung on the face. It latches into the frame at the lock edge, so it suits a single door or one leaf of a pair against a mullion. Where a pair of doors has no center mullion, you want vertical rods instead, latching at head and threshold: the 55 Series covers that with the 27 rim and 47 concealed vertical rod configurations. Concealed rods hide the hardware for appearance, surface rods are easier to service.
11) Will a 36 inch Von Duprin 5575 fit my door width, or do I need the 4 foot?
The 3 foot (36 inch) 5575 is field sizeable, so it can be cut down on site to suit narrower leaves. The 55 Series also comes in a 4 foot length for wider openings, and both sizes work on single doors and on pairs. Measure the door width first: if the leaf is wider than what a 36 inch crossbar can cover, take the 4 foot.
12) Can the Von Duprin 5575 be dogged down for daytime push/pull traffic?
Yes, with a hex key. Hex key dogging holds the crossbar retracted so the door pushes and pulls freely during business hours, then a turn of the key puts it back to latching. Worth knowing that hex key dogging is a mechanical feature not permitted on fire doors, which is consistent with the 5575 being a panic device rather than fire exit hardware.
13) Can I tie a Von Duprin 5575 into an access control system or monitor the door?
Both are available. An RX request-to-exit switch can be ordered on the device, which signals your access control or alarm panel when someone pushes the bar. The 55 Series also takes the E8875 electrified option for pairing with access control, fire alarm or remote switching. Order the switch with the device rather than trying to add it later.
14) What is a good alternative to the Von Duprin 5575 for an aluminum storefront door?
The 5575 is a narrow stile device, so it already suits a narrow aluminum stile, but the crossbar profile is a period look. If you want a narrow stile mortise device without that styling, the Adams Rite 8400 Series is a narrow stile mortise exit device built for aluminum doors, and the Sargent 8304 is a narrow stile mortise device in night latch function. All three are Grade 1. The Adams Rite 8400 and the 5575 are both non-fire-rated life safety devices.
15) Does the Von Duprin 5575 meet Grade 1 for a school or healthcare facility?
Certified to ANSI/BHMA A156.3, 2008 Grade 1, ANSI/UL 305 and CAN/ULC-S132, and UL listed for accident hazard installations. Grade 1 is the highest ANSI/BHMA durability tier and is what most institutional specs call for on high traffic egress doors. What it does not carry is a fire label, so on any labeled opening in that facility you need the -F configuration instead.
16) What is a simpler exit only mortise device if I do not need lever trim or a night latch?
The Von Duprin 5575 covers exit only as one of its trim functions alongside Dummy Trim, Lever, Lever with Blank Escutcheon, Lever with Dummy Trim, and Night Latch. If the opening only ever needs push-to-exit with no outside trim at all, the Falcon 25-M-EO is a Grade 1 wide stile mortise exit device supplied exit only in a 36 inch, 3 foot length with a 1-3/4 inch door thickness, and the BEST Precision 2301 is an exit only mortise device with heavy wrought construction. Both are wide stile devices, so the door stile has to accept a wide stile chassis; the 5575 is the narrow stile option.
17) Is the Sargent 8904 a substitute for the Von Duprin 5575 night latch device?
Not directly. The Sargent 8904 is a Grade 1 night latch mortise exit device but it is a wide stile device and runs on 24VAC/DC, so it is an electrified wide stile solution. The Von Duprin 5575 is a narrow stile mechanical crossbar device; its electrified path is the E8875 option, and door position monitoring is added through the RX Request to Exit switch. If the stile is narrow, the 8904 chassis will not suit the door regardless of function match.
18) Adams Rite 8300 or Von Duprin 5575 for a life safety egress door that is not fire rated?
Both are Grade 1 non-fire-rated mortise exit devices. The difference is the door. The Adams Rite 8300 Series is a wide stile life safety mortise exit device for wood and hollow metal doors. The Von Duprin 5575 is a narrow stile crossbar device, UL listed for accident hazard installations to ANSI/UL 305 and CAN/ULC-S132, with a field reversible 7500 mortise lock and a non-handed auxiliary deadlocking bolt. Measure the stile first: a wide stile chassis will not land on a narrow stile door.
19) Is the Sargent 1256NB-8710G an alternative to the Von Duprin 5575?
They solve different openings. The Sargent 1256NB-8710G is a Grade 1 narrow stile device, but it is an 84 inch fire rated surface mount vertical rod exit device with electric latch retraction, which latches at the head and sill of the door. The Von Duprin 5575 is a mortise lock device that latches into the frame at the strike with a 1/2 inch latch throw, in a 36 inch crossbar length. Within the 55 Series, the surface vertical rod configuration is the 27 device and concealed vertical rod is the 47, so a vertical rod opening stays in the same series without changing to a mortise chassis.
20) What crossbar options does the Von Duprin 5575 come with, and when would I need the knurled one?
Three crossbars: standard, RCB reinforced, and KN knurled. Knurling is a tactile hazard warning, the raised texture that tells someone by feel that the door leads somewhere hazardous, which is a common requirement on mechanical and electrical room doors. The reinforced crossbar is the one to take on abuse-prone openings such as school corridors or loading areas.
21) What finishes does the Von Duprin 55 Series crossbar exit device come in for matching existing hardware?
Eight finishes, so matching a run of existing openings is usually possible: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 643E aged bronze and 693 black. The brass and bronze options are why this crossbar device turns up on historical and retro-inspired buildings where a modern push bar would look out of place.
22) Do I need to order the Sargent 810 trim if I buy a Von Duprin 5575 in the dummy function?
No. The Sargent 810 is a Grade 1 dummy pull exit device trim from the PE80 Series, a trim piece rather than a device, and it is matched to Sargent exit devices. The Von Duprin 5575 carries dummy trim as an ordering choice on the device itself through the DT Dummy Trim and L-DT Lever with Dummy Trim functions, so the dummy configuration is selected with the 5575 rather than bought as a separate Sargent part.
