Von Duprin 3549A-EO-626-36 – Frequently Asked Questions

1) Will the Von Duprin 3549A-EO fit a narrow stile aluminum-look hollow metal door?
The 3549A-EO is built for narrow stile doors, fitting stiles as narrow as 2-1/8 inches (44 mm). It covers a 36 inch door width and adjusts up to 96 inches in height, with device lengths for door widths from 2 feet to 4 feet. If your stile is narrower than 2-1/8 inches, this device will not mount.
2) Does the 3549A-EO need to be ordered left or right hand?
No handing to specify. The concealed vertical cable device is non-handed, with one exception: if you add the SS signal switch option, handing applies.
3) What does exit only mean on the 3549A-EO, and can I add a lever or pull outside?
Exit only means there is no outside trim. The door pushes open from the inside and is secured from the outside with no key or lever function. If you need outside access, this is the wrong configuration, you want a trimmed version of the device instead.
4) Does the 3549A-EO meet a Grade 1 spec for an institutional door hardware schedule?
Yes. The device is certified to ANSI A156.3 - 2008 (LBL option 2014) Grade 1 and is UL listed for panic exit hardware, which is what most commercial and institutional egress specs call for. It is not fire rated, so rated openings in the same schedule need different hardware.
5) For a pair of doors, is it better to run concealed vertical cable devices on both leaves or to use a removable mullion with rim devices?
Both approaches close a double opening, and they differ in where the latching happens. The Von Duprin 3549A-EO latches into the frame head and the floor, with a vertical rod top strike and vertical rod bottom strike, and fits stiles as narrow as 2 1/8 inches, so no center post sits in the clear opening. The Falcon 4023 is a steel mullion for double door exit device applications, which puts a vertical post between the leaves for rim devices to latch against. Choose the 3549A-EO where a clear unobstructed opening matters for traffic or equipment movement, and the mullion approach where rim devices are already standardized across the building.
6) Can a Falcon 610061 concealed vertical top rod be used in place of a Von Duprin 3549A-EO?
No. The Falcon 610061 is a concealed vertical top rod component for Falcon F-25-C and F-25-CWDC exit devices in the 245 Series, so it is a single rod inside an existing Falcon device, not a complete exit device. The Von Duprin 3549A-EO is a full narrow stile concealed vertical cable exit device for a 36 inch wide door, adjustable in the 82 to 96 inch height range, in an exit only function. If the goal is to repair a Falcon concealed vertical rod device, the 610061 rod is the matching component; if the goal is to hardware a narrow stile opening with a complete device, the 3549A-EO is the one to order.
7) Will the 3549A-EO latch bolts work with my existing top and bottom strikes?
Top and bottom bolts throw 1/2 inch (13 mm) and are deadlocking anti-friction type. They land in vertical rod top and bottom strikes, and the device centerline sits 39-13/16 inches (1006 mm) from finished floor, so existing strike locations have to match that geometry.
8) How do you hold the 3549A-EO in a pushed-down, free-swinging state during business hours?
Hex key dogging comes standard, so a hex wrench holds the pushpad depressed and the latches retracted. Other dogging options are available: cylinder dogging (CD), cylinder dogging with security indicator (CDSI), hex dogging with security indicator (HDSI), and less dogging (LD). If the opening is keyed and you want staff to dog it with a key instead of a wrench, order CD.
9) What mounting hardware ships with the Von Duprin 3549A-EO?
Sex bolts are furnished for 1-3/4 inch (44 mm) to 2-1/4 inch (57 mm) metal doors. The #425 sex bolt is standard for the end case and the #325 is standard for the exit only configuration. That covers standard commercial 1-3/4 inch hollow metal doors without extra fasteners.
10) Can the 3549A-EO be electrified for access control or a delayed egress application?
Yes, and the option list is broad: electric latch retraction (EL), quiet electric latch retraction (QEL), Chexit delayed exit (CX), alarm exit kit (ALK), emergency secure lockdown (ESL), request to exit (RX), signal switch (SS), and Allegion Connect (CON). Note that choosing SS makes the device handed.
11) Can I order the 3549A-EO without a bottom latch for a dirty or uneven threshold?
Yes, specify LBL (less bottom latch). That eliminates the bottom bolt and strike, which is the usual move where debris, carpet, or an out-of-level slab fouls a floor strike. Related mechanical options include Pullman latch (PL), weep holes (WH), security screws (SEC), sex bolts (SNB), glass bead kit (GBK), hurricane (HH), accessible device (AX), safety glow (SG), and Insulclad kits for 1/2 inch and 1/4 inch panels.
12) What should I use on a fire rated opening instead of the 3549A-EO?
The Von Duprin 3549A-EO is not fire rated, so it suits panic exit openings rather than fire doors. Among the related exit device parts, the Accentra 7110F top latch component, 60-7010-0050-999, serves the 7110F device family, while the Accentra 60-7010-0049-999 serves the 7110 and 7120. For a fire rated leaf, specify a device labeled for fire exit hardware for that series rather than a panic only device, and keep the 3549A-EO for non rated narrow stile hollow metal openings where exit only operation with no outside trim is wanted.
13) My concealed vertical device has a worn top latch. Do I need a whole new device, or will an Accentra top latch part work?
Top latch replacement components are brand and series specific. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110 and 7120 exit devices, and the 60-7010-0050-999 is the top latch replacement for the 7110F, so both serve Accentra devices rather than Von Duprin ones. If the device on the door is a Von Duprin 33/35 Series concealed vertical cable unit, replacing the complete 3549A-EO keeps the center case, cables, and top and bottom bolts as a matched set; it carries hex dogging as standard and ANSI Grade 1 certification.
14) Do I need a rim cylinder housing like the Arrow 16RCR-27 to go with a 3549A-EO?
Not for the standard configuration. The Arrow 16RCR-27 is an SFIC rim housing for 6 or 7 pin cores in the 24/25 Series, which is used where a rim cylinder operates or dogs a device. The 3549A-EO is supplied exit only with hex dogging as standard, so no cylinder is required to put it in service. A cylinder housing only enters the conversation if cylinder dogging is specified in place of hex dogging.
15) What finishes does the 3549A-EO come in for matching other doors in a building?
Two finishes: satin chrome and dark bronze anodized. Satin chrome is the usual match for brushed stainless and aluminum storefront hardware, dark bronze anodized for bronze anodized frames.
16) How much space does the 3549A-EO 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) and the mechanism case is 2-1/4 x 2-1/4 inches (57 x 57 mm). The cover is a one-piece center case cover. Those case dimensions are what has to clear glass stops and vision lite trim on a narrow stile door.
17) What are the vertical cables made of on a concealed vertical cable exit device?
On the 3549A-EO the cables are stainless steel, 7/32 inch (6 mm) diameter, which is what gets you corrosion resistance on exterior and wash-down openings where exposed steel rods would suffer.
18) Will a Falcon 525 mullion stabilizer help a concealed vertical cable installation?
No, those address a different problem. The Falcon 525 is an aluminum mullion stabilizer for exit devices, so it stiffens a mullion in a double door application. The Von Duprin 3549A-EO does not use a mullion; it latches at a vertical rod top strike and a vertical rod bottom strike, so stabilizing hardware for a center post has nothing to attach to. Specify the 525 only if the opening keeps a mullion with rim devices.
19) Is a Falcon T Series deadlatch an alternative for securing the same opening?
They are different kinds of hardware. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for T Series devices, a latch component used where a square corner deadlatch is already in the door. The Von Duprin 3549A-EO is a complete concealed vertical cable exit device with top and bottom bolts for narrow stile hollow metal doors, carrying ANSI Grade 1 certification. Use the Falcon part to restore an existing T Series latch and the 3549A-EO where panic exit hardware is being specified for the leaf.
