Von Duprin 3549A-EO-711 48 – Frequently Asked Questions

1) Will a Von Duprin 3549A concealed vertical cable exit device fit a narrow stile aluminum or hollow metal door?
The 3549A fits stiles as narrow as 2-1/8 inches (44 mm), and it's built for hollow metal single and double doors. If your stile measures under 2-1/8 inches, no narrow stile device in this family will land on it and you need a different opening solution. The cables and latches run inside the door, so the door has to be prepped for concealed vertical hardware, not surface rod.
2) What door width and height does the Von Duprin 3549A-EO-711-48 cover, and can it be cut down?
It's the 48 inch wide device, covering door sizes from 2 feet 8 inches up to 4 feet (813 mm to 1219 mm). Height adjusts up to 96 inches, with the device sized for 82 to 96 inch doors. Order by the widest door in the set and size down at install rather than ordering a device too short.
3) Can I use the Von Duprin 3549A on a fire rated door?
No. The 3549A-EO-711-48 is not fire rated. It is UL listed for panic exit hardware and meets ANSI A156.3 - 2008 (LBL option 2014) Grade 1, which covers panic hardware, not fire door assemblies. Hex dogging is standard on it, and dogging is not permitted on fire exit hardware anyway. For a fire rated opening you need a fire exit device, typically a less-dogging version.
4) Does the 3549A exit device come with outside trim or a lever to get back in?
No outside trim. EO means Exit Only: push the pad from the inside to get out, and there is no operating trim on the pull side. If your opening needs re-entry from outside, you need a trim-prepped function instead, and you'd order the trim separately. Where the door is a stairwell or rear exit that only ever needs egress, EO is the correct call.
5) Will the 3549A latch into my existing top and bottom strikes?
Top and bottom bolts throw 1/2 inch (13 mm) into vertical rod top and bottom strikes. That's a short throw, so the strike prep and the undercut have to be right: maximum door undercut is 3/4 inch (19 mm). If the gap under your door is bigger than that, the bottom bolt won't reach the floor strike and you'd be relying on the top latch alone. Latch cases measure 5-13/16 x 1-1/4 x 1-7/16 inches (147 x 32 x 37 mm).
6) Concealed vertical rod or a rim device with a mullion for a pair of doors?
A concealed vertical device like the 3549A latches at the head and the threshold, so a pair of doors secures with nothing in the opening between them. That's the reason to pick it: clear opening, nothing to remove for moving furniture, and the hardware hides inside the door. The trade is prep. The door has to be manufactured or prepped for concealed cables, and the floor needs a bottom strike with the undercut held to 3/4 inch. Rim devices are simpler to install and service but need a removable mullion between the leaves, such as the Falcon 4023 steel mullion. If the doors are already hung and unprepped, the mullion route is usually the shorter job.
7) Can the Falcon 610061 concealed vertical top rod be used in place of a Von Duprin 3549A-EO-711-48?
No - they are different classes of part. The Von Duprin 3549A-EO-711-48 is a complete narrow stile concealed vertical cable exit device, exit only, 48 inches wide and adjustable up to 96 inches, with 7/32 inch stainless steel cables running concealed in the door. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices - a single rod component that goes into an existing Falcon device, not a push bar and center case. A rod also is not a cable: the 3549A drives its top and bottom latches through cable, so a Falcon rod has nothing in the 3549A to attach to.
8) The top latch on my exit device is worn out - do I need a whole new device like the Von Duprin 3549A-EO-711-48, or just the latch?
It depends on which device is on the door. The Von Duprin 3549A-EO-711-48 is sold as a complete concealed vertical cable exit device with top and bottom latches, center case and push rail, so it is what you buy when you are replacing the opening's hardware outright. If the door carries an Accentra 7110 or 7120, the top latch is available on its own as the Accentra 60-7010-0049-999 top latch replacement component, and for the 7110F there is the 60-7010-0050-999 top latch replacement component. Those two are single-latch service parts for Accentra devices and will not mount to Von Duprin cable hardware.
9) How do I hold the Von Duprin 3549A unlocked during business hours?
Hex key dogging is standard, so you depress the pushpad and set it with a hex wrench to leave the door push-pull all day, then release it at close. Other dogging arrangements exist on the series if you'd rather key it: cylinder dogging (CD), CDSI, HDSI, or less dogging (LD) for openings where dogging isn't wanted. Cylinder dogging is the usual pick where you don't want maintenance staff or tenants dogging the door with a loose hex key.
10) What mounting height does the 3549A install at, and what fasteners come with it?
Centerline of the device sits 39-13/16 inches (1006 mm) from finished floor. Sex bolts are included, sized for 1-3/4 inch to 2-1/4 inch (44 mm to 57 mm) metal doors: #325 SNB standard on the EO device and #425 SNB for the end case. If your door falls outside that 1-3/4 to 2-1/4 inch range, the supplied sex bolts won't work and you need through-bolts to match your thickness.
11) Can I add electric latch retraction or a request-to-exit switch to the 3549A later?
These options are specified at order, not bolted on afterward, and the range is broad: electric latch retraction (EL), quiet electric latch retraction (QEL), Chexit delayed egress (CX), alarm exit kit (ALK), emergency secure lockdown (ESL), request to exit (RX), signal switch (SS), and Allegion Connect (CON). If the opening is going on an access control system, decide between EL/QEL for remote unlatching and RX for monitoring before the device ships, because retrofitting means replacing the device.
12) Are the concealed vertical rods on the 3549A actual rods, or cable?
Cable, not rod. The 3549A runs 7/32 inch (6 mm) diameter stainless steel vertical cables inside the door to drive the top and bottom latches. That matters when you're sourcing service parts or comparing against an older device: a rigid rod assembly like the Falcon 610061 concealed vertical top rod, which serves the 24 Series Monarch F-25-C devices, is a different mechanism and its parts do not carry across to a cable device.
13) Is the Von Duprin 3549A heavy duty enough for a school or hospital main egress door?
It's a commercial Grade 1 device under ANSI A156.3 - 2008 (LBL option 2014), UL listed for panic exit hardware, which is the top grade in that standard and the tier institutional specs normally call for. It's used on schools, healthcare, offices, retail, warehouse, multi-tenant residential, and government buildings. The one thing to confirm against your spec is fire: this device is not fire rated, so it doesn't belong on a rated stair or corridor opening.
14) For a pair of doors, is a mullion an alternative to running Von Duprin 3549A-EO-711-48 devices on both leaves?
Those are two different ways to secure a double opening. The Von Duprin 3549A-EO-711-48 latches top and bottom into the frame head and the floor through concealed vertical cables, with vertical rod top strike and bottom strike, so each leaf latches on its own and the opening stays clear between the leaves. The other approach is a removable mullion between the leaves, which gives rim devices something to latch into: the Falcon 4023 is a steel mullion for double door exit device applications. Going the mullion route means a post standing in the middle of the opening and rim devices rather than concealed vertical hardware, so it is a decision about how the opening is used, not a drop-in swap.
15) Does the Von Duprin 3549A-EO-711-48 take an SFIC cylinder like the Arrow 16RCR-27 rim housing?
Not in the exit only configuration. The 3549A-EO-711-48 is an exit only device with no outside trim, and it ships with hex dogging as its standard dogging configuration, so there is no outside cylinder and no cylinder dogging cylinder to house. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing for 24/25 Series hardware - it is the housing that carries a small format interchangeable core on a rim device with keyed outside access, which is a different way to configure an opening than exit only.
16) What finish is the 3549A-EO-711-48, and will it match other black hardware in the building?
Finish 711 is matte black anodized, listed as 622/711 matte black. That's the anodized black that pairs with other Von Duprin 711 hardware, closers and pulls specified in the same finish. Anodized black on aluminum reads slightly different from painted or powder coated black on steel accessories, so if you're matching existing openings, match to the 711 designation rather than to the word black.
17) How much space does the 3549A center case take up on the door face?
Center case measures 8-13/16 x 2-13/32 x 1-9/16 inches (208 x 62 x 40 mm) with a one-piece cover, and the mechanism case is 2-1/4 x 2-1/4 inches (57 x 57 mm). Those are the numbers to check against vision lites, glass stops, and any surface applied closer arm or card reader landing near the pushpad on a narrow stile door.
18) Where do I get the door prep template for installing a Von Duprin concealed vertical exit device?
Von Duprin publishes prep template indexes by door construction, and they're the documents to hand your door supplier before the leaves are ordered. There are separate indexes for hollow metal door prep and wood door prep, plus matching trim and strike template indexes for each. On a concealed vertical application the prep has to be right at manufacture, since the cable raceway and top and bottom latch pockets are inside the door.
19) Do I need mullion stabilizers such as the Falcon 525 with a Von Duprin 3549A-EO-711-48?
No. The Falcon 525 aluminum mullion stabilizers are an exit device accessory that steadies a mullion in a double door opening. The Von Duprin 3549A-EO-711-48 is a concealed vertical cable device that latches into a vertical rod top strike and a vertical rod bottom strike, so there is no mullion in the opening to stabilize. Stabilizers belong on rim device and mullion openings.
20) Will a Falcon T Series deadlatch work with a Von Duprin 3549A-EO-711-48?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for Falcon T Series hardware - a latch that fits a square corner prep in the door edge. The Von Duprin 3549A-EO-711-48 latches at the head and the sill instead, through a deadlocking anti-friction top and bottom bolt with 1/2 inch throw driven by concealed stainless steel cables. The two engage the opening in completely different places, so the T Series deadlatch is not a service part for it.
