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

1) Will the Von Duprin 3549A-EO fit a narrow stile aluminum-look hollow metal door?
The 3549A-EO concealed vertical cable device fits door stiles as narrow as 2-1/8 inches (44 mm) and is built for hollow metal single and double doors. If your stile measures less than 2-1/8 inches, this device will not mount.
2) What door width and height does the 3549A-EO-48 cover?
It is a 48 inch wide device, and the height adjusts from 82 up to 96 inches, covering door sizes from 2 ft 8 in to 4 ft (813 mm to 1219 mm). Device centerline sits 39-13/16 inches (1006 mm) off the finished floor.
3) Can I use the Von Duprin 3549A-EO on a fire rated opening?
No. The 3549A-EO is not fire rated. It is UL listed for panic exit hardware only, so on a labeled door you need a fire rated exit device instead (no mechanical dogging allowed on those).
4) Does the 3549A-EO latch a pair of doors without a mullion?
Yes. It is a concealed vertical cable device that latches top and bottom, so a pair of doors is secured at the head and the threshold with no center mullion needed. Both top and bottom vertical rod strikes apply. If you would rather keep a mullion arrangement with rim devices, a steel mullion like the Falcon 4023 is the other approach.
5) What is the latch bolt throw on the 3549A, and how much door undercut can it tolerate?
Top and bottom bolts are deadlocking anti-friction latch bolts with a 1/2 inch (13 mm) throw. Maximum door undercut is 3/4 inch (19 mm), so if your door is cut higher than that above the floor the bottom bolt will not engage the strike.
6) Is there outside trim with the EO version of the 3549A?
No. EO means exit only, so there is no outside trim and no outside operation at all. The door is push-to-exit from the inside and blank outside. If you need outside access, you need a trim-prepped function rather than EO.
7) On a pair of doors, do I need a mullion like the Falcon 4023 if I use concealed vertical cable exit devices?
Not for the latching itself. The Von Duprin 3549A-EO-4FT latches into vertical rod top and bottom strikes in the frame head and floor, so each leaf is secured independently and no center post is required. The Falcon 4023 is a steel mullion for double door exit device applications, which is what you add when you are using rim exit devices that need a vertical surface to latch into at the center of the opening; the Falcon 525 aluminum mullion stabilizers are the related accessory for those installations. Choose the mullion route if the opening must also accept rim devices or if the project drawing calls for a removable mullion; choose the concealed vertical cable device if you want a clear, unobstructed opening between the two leaves.
8) I need panic hardware on a fire rated opening - does the 3549A-EO work there?
The Von Duprin 3549A-EO-4FT is not fire rated, so for a labeled opening you need to specify fire rated panic hardware instead. The same split shows up at the component level on other brands: the Accentra 7110/7120 top latch replacement component is a non fire rated part, while the separate Accentra 7110F top latch component serves the F, or fire rated, version of that device. For the Von Duprin opening, use the 3549A-EO where dogging and a non labeled door are acceptable, and move to a fire labeled device family where the door carries a label.
9) Does the 3549A-EO come with mounting fasteners, or do I order them separately?
Sex bolts are furnished. The #325 SNB is standard on exit only devices and the #425 SNB is standard for the end case, covering metal doors 1-3/4 inches (44 mm) to 2-1/4 inches (57 mm) thick.
10) What dogging comes on the 3549A, and can I get cylinder dogging instead?
Hex key dogging (HD) is standard. Other dogging configurations offered on the device include cylinder dogging (CD), CDSI, HDSI, and less dogging (LD), which you specify at time of order.
11) Can the 3549A be electrified for access control or delayed egress?
Yes, the 3549A supports electric latch retraction (EL), quiet electric latch retraction (QEL), Chexit delayed exit (CX), emergency secure lockdown (ESL), request to exit (RX), signal switch (SS), alarm exit kit (ALK), and Allegion Connect (CON). These are ordered as option suffixes on the device, not added in the field.
12) What ANSI grade does the Von Duprin 3549A meet?
Grade 1 under ANSI A156.3 - 2008 (LBL option 2014), and UL listed for panic exit hardware. That is the level institutional and MRO specs normally call for on high-traffic egress doors.
13) How much of the 3549A hardware actually shows on the door face?
Only the touchbar assembly and cases are exposed; the vertical actuation runs inside the door on 7/32 inch (6 mm) stainless steel cables. Center case is 8-13/16 x 2-13/32 x 1-9/16 inches (208 x 62 x 40 mm), mechanism case 2-1/4 x 2-1/4 inches (57 x 57 mm), and each top and bottom latch case 5-13/16 x 1-1/4 x 1-7/16 inches (147 x 32 x 37 mm). That is the clean look you pick concealed over surface vertical rod for.
14) My exit device only needs a new top latch - is the Von Duprin 3549A-EO the right order?
Only if the device being replaced is a Von Duprin narrow stile concealed vertical cable unit, since the 3549A-EO-4FT is a complete exit only device with its own top and bottom latch cases and cables rather than a loose latch. For a top latch repair on an Accentra device, the component-level parts are the Accentra 7110/7120 exit device top latch replacement component and, for the fire rated version of that device, the Accentra 7110F top latch replacement component. Both of those are single-component orders for an existing Accentra chassis and will not mount to a Von Duprin device.
15) Can I add key access to a 3549A-EO using an Arrow 16RCR-27 rim cylinder housing?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing from the Arrow 24/25 Series, intended for rim exit devices that accept a rim cylinder for outside key retraction or cylinder dogging on that platform. The Von Duprin 3549A-EO-4FT is supplied in the exit only configuration with no outside trim and comes standard with hex key dogging, and it belongs to the Von Duprin 33/35 Series, so Arrow rim housings are not a cross-brand fit. If you need keyed outside access or key dogging on the Von Duprin opening, specify a device configuration that includes outside trim or cylinder dogging rather than adapting a rim cylinder housing.
16) What should I use instead of a concealed vertical cable device on an aluminum narrow stile storefront door with a deadlatch?
A concealed vertical cable device like the Von Duprin 3549A-EO-4FT is engineered for narrow stile hollow metal single and double doors, with the cables and vertical latching concealed inside the door and top and bottom strikes in the frame and floor. If the opening is an aluminum storefront leaf that latches with a deadlatch rather than vertical rods, the corresponding part on that type of door is a deadlatch such as the Falcon T Series 2-3/8 inch square corner deadlatch replacement part. Confirm which latching method the existing door is prepped for before ordering, since the two preps are not interchangeable.
17) Where do I get the door prep dimensions for a Von Duprin concealed vertical exit device install?
Von Duprin publishes template indexes for both hollow metal and wood doors, plus separate indexes for trims and strikes on each substrate. Pull the hollow metal door prep index and the hollow metal trims and strikes index before cutting a door, since concealed cable devices need the stile cavity prepped.
18) What finish does the 3549A-EO-711 come in, and will it match modern black hardware?
Finish 711 is matte black anodized (622/711 matte black). It is the only finish offered on this configuration, so for a building standardized on black lever trim and closers it drops right in.
