Von Duprin 3527AEO 3 US26 – Frequently Asked Questions

1) Can I use the Von Duprin 3527A on a fire rated door?
No. The 3527A-3ft is a panic device, not a fire exit device, and it is not fire rated. Two reasons matter on a rated opening: fire exit hardware cannot have dogging, and the 3527A ships with hex key dogging as standard. For a rated pair, look at a fire rated surface vertical rod device instead, such as the Adams Rite 3100 Series or the Arrow S1150, both of which we carry fire rated.
2) Do I have to order the 3527A handed?
The device itself is non-handed, so one part number works on left or right hand doors. The one exception is the SS signal switch option, which is handed. Handing still gets specified on the order (RHR or LHR) because the trim and switch prep follow the door, so know your hand before you order even though the chassis does not care.
3) Will a surface vertical rod exit device secure a pair of doors without a mullion?
Yes, and that is the main reason to pick one. A vertical rod device like the 3527A latches into the head frame and the threshold on each leaf, so a pair of doors is secured without a removable mullion in the middle. That keeps the full clear opening free for gurneys, carts, and furniture moves. A rim device on a pair needs a mullion between the leaves; if you want the wide clear opening, vertical rod is the right call.
4) What is the less bottom rod option on a Von Duprin 3527A and when should I use it?
Less bottom rod (LBR) deletes the bottom rod and floor strike, so nothing runs to the threshold. Order it where the bottom rod would collect dirt, get kicked, or drag on an uneven floor, which is common in schools and hospitals. With LBR the device latches only at the head, so you give up the bottom latching point. If you go LBR and want an electric strike at the head, the ES top pullman latch option is the one to specify.
5) Does the 3527A meet the 5 lb ADA opening force requirement?
Only with the AX option specified. The AX accessible device is certified to the 5 lb force requirement of the 2010 ADA (Chapters 404.2.7 and 30934) and the 2013 California Building Code Chapter 11B-309.4. The base device is ANSI/BHMA A156.3 2014 Grade 1 and UL listed under ANSI/UL 305 for panic hardware. If your spec calls out 5 lb maximum operating force, AX is not optional.
6) How do I tie a Von Duprin 3527A into my access control system?
Several ways, and they are ordered as options on the device. For monitoring, RX gives request to exit, LX monitors the latchbolt, LX-RX does both, RX2 is a double RX switch, and WP-RX is the waterproof version for exterior openings. For remote unlocking, EL is electric latch retraction and QEL is the quiet version, which is what most people pick for lobbies and offices where the solenoid clack is a problem. PN is pneumatic. If you need delayed egress, the CX (CHEXIT) option meets NFPA and IBC delayed egress with a 15 second hold and nuisance alarm. Alarm kits are also available as ALK, RX-ALK, and LXRX-ALK.
7) What trim do I need to order with a 3527A if people have to get back in from outside?
Exit only (EO) has no outside trim at all, so pick a trim function if the door needs outside access. Lever trim (L) with a keyed escutcheon is the standard for a door people use both ways, and the lever design is a separate choice: 01, 02, 03, 05, 06, 07, 17, or 18, with 06 as the default. NL night latch or NL-OP with the optional pull suits a service door where a key retracts the latch. Thumbturn options (T, TL, and their blank escutcheon versions) work where a cylinder is not wanted, and DT is a dummy trim pull only.
8) Does the 3527A come with mounting screws, or do I have to order fasteners separately?
Fasteners are in the box. It ships with 1-3/4 inch and 2-1/4 inch wood and metal door fasteners plus sex nut and bolt (SNB), so the device mounts on either a wood door or a hollow metal door without a separate hardware order. What is not included is outside trim, a cylinder for CD cylinder dogging or a keyed trim function, and any power supply for EL or QEL latch retraction. Order those on the same PO or the door does not finish.
9) Our door has a wide stile - what takes the place of the Von Duprin 3527A-3ft?
The Von Duprin 3527A-3ft is built for narrow stile doors down to 1-3/4 inch stiles, so a wide stile door calls for a wide stile device. Grade 1 wide stile surface vertical rod peers at 36 inches include the Corbin Russwin ED5400 for 1-3/4 inch doors, which is exit only and accepts trim, and the TownSteel 8900 Series ED8927 for a 36 by 84 inch opening, which is wood door compatible. The Falcon 20 Series and Falcon 25-V-EO are Grade 1 wide stile 36 inch devices for 1-3/4 inch doors in an exit only function.
10) What is the closest narrow stile surface vertical rod equivalent to the Von Duprin 3527A-3ft for a 36 inch door?
The Von Duprin 3527A-3ft is a Grade 1 narrow stile surface vertical rod exit device for 36 inch doors on 1-3/4 inch thick doors. The closest peers of the same description are the Corbin Russwin ED4400, a Grade 1 narrow stile surface vertical rod device for 36 inch doors at 1-3/4 inch door thickness, and the TownSteel 8900 Series ED3727, a Grade 1 narrow stile surface vertical rod device for a 36 by 84 inch opening. The Falcon 19-V-EO is also Grade 1 narrow stile at 36 inches, but it is an exit only device, so it does not take the lever, thumbturn and night latch trim functions the 3527A offers.
11) The opening is fire rated - can the Von Duprin 3527A-3ft be used, and what should go on it instead?
The Von Duprin 3527A-3ft carries a fire rating of No, so a fire rated opening needs a fire rated device. Fire rated surface vertical rod peers include the Adams Rite 3100 Series, a Grade 1 wide stile device for 1-3/4 inch doors, the Arrow S1150, an exit only device listed for narrow or wide stile at 1-3/4 inch thickness, the Sargent 2727 reversible Grade 1 wide stile device, and the TownSteel 9700 Series EF9727, a Grade 1 heavy duty wide stile device for a 36 by 84 inch opening that is wood door compatible. On a narrow stile aluminum opening the Arrow S1150 is the one of those four that covers narrow stile.
12) Can an exit only device be used in place of the Von Duprin 3527A-3ft when outside trim is needed?
No. The Von Duprin 3527A-3ft can be ordered with outside trim functions including lever, lever with blank escutcheon, night latch, night latch with optional pull, thumbturn and thumbturn with unlock, so it covers openings that need controlled entry from the pull side. Several peers that look similar on paper are exit only and will not take that trim: the Falcon 19-V-EO, the Falcon 24-V-EO, the Falcon 25-V-EO, the Arrow 3700 Series exit bar and the Orca OED56 Series are all listed as exit only. The Corbin Russwin ED4400 is exit only but accepts trim, so it is the narrow stile peer to look at when outside trim is part of the opening.
13) Can I dog the 3527A open during business hours, and can I get a cylinder instead of a hex key?
Standard build is hex key dogging, which holds the push pad depressed so the door pushes free during open hours. Two other choices on the order form: CD cylinder dogging, so staff can dog it with a key instead of an allen wrench, and LD less dogging where the door must stay latched at all times. Cylinder dogging is the usual pick when you do not want a loose hex wrench living behind the front desk.
14) How is the Von Duprin 3527A different from the 3327A?
Mechanism case finish is the difference. The 3527A has a smooth one-piece center case cover; the 3327A is the grooved case version of the same 33/35 Series device. Function, stile capability, and grade are the same family, so the choice is architectural appearance, not performance. Smooth is the usual pick where the hardware is visible in a finished lobby.
15) I have a hollow metal door with a wide stile. Should I still buy the narrow stile 3527A?
No need. A narrow stile device fits a wide stile door but you are paying for stile capability you do not use, and a wide stile device gives you a longer push pad, which is easier to hit. For a 36 inch wide stile opening at Grade 1 we carry the Corbin Russwin ED5400, the Falcon 20 and 25 Series, the Sargent 3727, and the TownSteel ED8927. If the wide stile opening is fire rated, the Sargent 2727 and the TownSteel EF9727 are the fire rated ones.
16) How high off the floor does the Von Duprin 3527A push pad mount?
Device centerline is 39-13/16 inches from finished floor. That is the number to put on your shop drawing and the one to check against existing hardware if you are replacing devices across a building and want the push pads to line up door to door. Panic hardware operating height has code limits, so hold the stated centerline rather than eyeballing it.
17) Will the 3527A latch into the strikes already on my frame?
Latch throw is 3/4 inch top and bottom. A surface vertical rod device uses its own top strike at the head and a floor strike at the threshold, and those are matched to the device, so plan on the Von Duprin strikes rather than reusing whatever is in the frame from another brand. If your existing strike pockets came off a different manufacturer's vertical rod device, the prep will not line up and you will be drilling.
18) Can I add security dogging indicators or electric latch retraction to a 3527A already installed on my doors?
Yes. Von Duprin offers field-configurable options and retrofit kits for the 33/35 Series, including CDSI and HDSI security dogging indicators that show at a glance whether the device is dogged, QEL quiet electric latch retraction, and RX request to exit and LX latchbolt monitoring switches for access control tie-in. That matters for a facility standardizing on one device now and adding lockdown or card access later.
19) Is there a lighter duty or Grade 2 alternative to the Von Duprin 3527A-3ft?
The Von Duprin 3527A-3ft is certified to ANSI/BHMA A156.3 Grade 1. Grade 2 surface vertical rod peers are the Dexter ED2000 Series, a non fire rated Grade 2 panic device, and the TownSteel TS5100 Series, a Grade 2 heavy duty wide stile device for a 36 by 84 inch opening. Design Hardware also splits its line by duty: the 1000V Series is heavy duty and the 2000V Series is standard duty, both non fire rated at 33 inches. A Grade 2 device carries a different ANSI cycle and strength classification than the Grade 1 3527A, which matters where a specification or facility standard calls out the grade.
20) What is the difference between the Von Duprin 3527A-3ft and the Corbin Russwin ED7400 for a narrow stile door?
Both are Grade 1 narrow stile surface vertical rod exit devices for 36 inch doors, and the Corbin Russwin ED7400 is listed for 1-3/4 inch door thickness like the 3527A-3ft. The difference is the actuator: the ED7400 is a crossbar device that is exit only and accepts operator trim, while the 3527A-3ft is a push pad device with a smooth mechanism case. If a facility is standardizing on one look across a run of doors, the crossbar and the push pad will not match visually.
21) Which surface vertical rod devices are reversible or non-handed like the Von Duprin 3527A-3ft?
The Von Duprin 3527A-3ft is non-handed, which is why a single part number covers both hands on a pair of doors. Among the peers, the BEST Precision 5201 Series is a reversible 36 inch surface vertical rod device, the Sargent 2727 is a reversible Grade 1 fire rated device, and the Orca Hardware OED56 Series is a non-handed 36 inch exit only device supplied less bottom rod in aluminum finish for 1-3/4 inch doors. Reversible and non-handed both cut the number of part numbers a multi-door project has to stock.
22) Is the Sargent 12-8710 a substitute for the Von Duprin 3527A-3ft?
No. The Sargent 12-8710 is a Grade 1 fire rated wide stile surface vertical rod device in a dummy function, meaning it does not latch and is used where a device is needed for appearance or push side operation only. The Von Duprin 3527A-3ft is a working panic device with a 3/4 inch latch throw and hex key dogging, certified to ANSI/BHMA A156.3 Grade 1 and UL listed for panic hardware. The two are not interchangeable on an egress opening.
23) What Grade 1 alternatives to the Von Duprin 3527A-3ft are confirmed for wood doors?
The Von Duprin 3527A-3ft ships with 1-3/4 inch and 2-1/4 inch wood and metal door fasteners with SNB included, so it mounts on wood as well as hollow metal. Among the peers, TownSteel lists wood door compatibility outright: the 8900 Series ED3727 is Grade 1 narrow stile and not fire rated, the 8900 Series ED8927 is Grade 1 wide stile and not fire rated, and the 9700 Series EF9727 is Grade 1 heavy duty wide stile and fire rated. All three are sized for a 36 by 84 inch opening, matching the 36 inch size of the 3527A-3ft.
24) Which alternatives to the Von Duprin 3527A-3ft come standard less bottom rod?
The Von Duprin 3527A-3ft can be ordered less bottom rod, which removes the bottom latch and floor strike on openings where the threshold is a problem. Among the peers, the Orca Hardware OED56 Series is supplied less bottom rod as its standard configuration, a 36 inch non-handed exit only device in aluminum finish for 1-3/4 inch doors that is not fire rated. The 3527A-3ft also offers an ES top pullman latch for electric strike applications with the less bottom rod option, which is what an access control integrator needs on that same opening.
25) What finishes can I get a Von Duprin 3527A in to match the rest of my building?
Ten finishes, covering the usual commercial specs: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 628 aluminum, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. On aluminum storefront, 628 aluminum and 710 dark bronze anodized are the two that normally match the frame; 626 satin chrome is the common pick for institutional interiors.
26) Which Grade 1 surface vertical rod devices can replace the Von Duprin 3527A-3ft without specifying a stile width?
The Von Duprin 3527A-3ft is a narrow stile device that fits stiles as narrow as 1-3/4 inch. Two peers are not tied to one stile width: the Arrow S1150, listed for narrow or wide stile at 1-3/4 inch door thickness in a fire rated exit only configuration, and the Dexter ED1000 and ED1500 Series Grade 1 surface vertical rod devices. That flexibility matters on a mixed campus where some openings are aluminum narrow stile and others are hollow metal.
