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

1) Will a Von Duprin 3549A concealed vertical rod exit device fit a narrow stile hollow metal door?
Down to a 2-1/8 inch (44 mm) stile. The smooth mechanism case on the 3549A is what sets that limit, so hollow metal profiles with stiles at or above 2-1/8 inches take it. Anything narrower than that and you need a different device family.
2) Is the Von Duprin 3549A-EO fire rated? I need panic hardware for a rated stair door.
No. The 3549A-EO is a panic device, not fire exit hardware, and it carries hex dogging as standard, which is exactly what a fire door cannot have. For a rated opening you need the fire-rated version of the device with less dogging. Use this one on non-rated egress openings only.
3) Can I use the Von Duprin 3549A CVR on a pair of doors without a mullion?
Yes, that is the point of a concealed vertical rod device. The 3549A latches at the head and at the threshold using a vertical rod top strike and a vertical rod bottom strike, so a pair of doors is secured with no center mullion and the opening stays clear. A rim device on the same pair would need a removable mullion such as the Falcon 4023 steel mullion to have something to latch into.
4) How much clearance do I need under the door for a Von Duprin concealed vertical rod device?
3/4 inch (19 mm) is the maximum door undercut the 3549A allows. The bottom bolt has to reach the floor strike, so if the door is undercut more than 3/4 inch for carpet or an air return, the bottom latch will not engage and you should be looking at a less bottom rod arrangement instead.
5) What does EO mean on the Von Duprin 3549A, and can I add a lever to get back in?
EO is exit only. There is no outside trim and no cylinder, so the door is pull-side egress with no key or lever entry from outside. If you need outside access, that is a different trim configuration ordered with the device, not an accessory added later. Mount it with #325 sex bolts for the EO device and #425 for the end case.
6) Is the Von Duprin 3549A handed? I'm ordering for both leaves of a pair.
Non-handed as built, because the vertical cable design does not care which way the door swings. The one exception is the signal switch (SS) option, which is handed. So for a standard pair with QEL you order the same device for both leaves; add SS and you have to call handing per leaf.
7) Is the Falcon 610061 concealed vertical top rod an equivalent to the Von Duprin RX-QEL-3549A-EO-626-36-CON?
No. The Von Duprin RX-QEL-3549A-EO-626-36-CON is a complete concealed vertical rod exit-only panic device, 36 inches wide, Grade 1, with Quiet Electric Latch Retraction and Allegion Connect built in. The Falcon 610061 is a concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC exit devices - a single rod component that fits an existing Falcon device rather than a push-bar assembly with electrified latch retraction. If the door already carries a Falcon F-25-C and only the top rod has failed, the 610061 is the part that addresses it; if the opening needs the whole egress device with access control integration, the Von Duprin device is what does that job.
8) What is needed to pair two Von Duprin RX-QEL-3549A-EO-626-36-CON devices on a double door, and does a mullion work instead?
The Von Duprin RX-QEL-3549A-EO-626-36-CON is a concealed vertical rod device, and its top and bottom vertical rod strikes latch into the frame head and the floor, so a pair of them on a double door needs no center post. A removable mullion such as the Falcon 4023 steel mullion is the accessory for double door openings running rim devices, which latch into the mullion instead of the frame head - a different approach to the same opening, not an add-on to a concealed vertical rod pair. The Falcon 525 aluminum mullion stabilizers likewise belong to a mullion-based setup. Where the opening cannot take a floor strike, the rim plus mullion route is the one to price out.
9) Will the 1/2 inch latch bolt on the Von Duprin 3549A work with my existing top and bottom strikes?
The top and bottom bolts are deadlocking anti-friction latch bolts with a 1/2 inch (13 mm) throw. That is a shallower throw than a rim or mortise latch, so the strikes have to be the matching CVR top and bottom strikes prepped for this device. Existing rim strike prep will not accept it.
10) How far does the push bar on the Von Duprin 3549A stick out into the opening?
Push bar projection is 3-13/16 inches (97 mm) at neutral and 3-1/16 inches (78 mm) depressed. That matters on a tight vestibule or where a door swings toward a wall or a second leaf, since the neutral figure is what you clear against. The center case measures 8-13/16 x 2-13/32 x 1-9/16 inches and the top and bottom latch cases are 5-13/16 x 1-1/4 x 1-7/16 inches.
11) What does QEL add over standard electric latch retraction on a Von Duprin exit device?
QEL is Quiet Electric Latch Retraction. It pulls the top and bottom latches back electrically so the door can be held in a push-pull state or released by an access control system, and it does it without the buzz of a solenoid-driven EL device. In a library, a courtroom, a patient floor, or an executive suite, that noise difference is the whole reason to specify QEL. The CON suffix on this unit is factory-installed Allegion Connect for monitoring and control.
12) Does the Von Duprin 3549A use rods or cables inside the door?
Cables, not solid rods. They are 7/32 inch (6 mm) diameter stainless steel and run concealed inside the door leaf. Cable is what allows the non-handed build and keeps the bolt travel out of sight, but it does mean the door has to be prepped for a concealed vertical device, which is a factory or shop prep on hollow metal rather than something you cut in on site.
13) Should I choose a concealed vertical rod exit device or a surface vertical rod for a commercial double door?
Concealed, like the 3549A, puts the cables and latch cases inside the door for a clean face and no exposed hardware to catch carts or get vandalized, but it needs a door prepped for it and the door has to come out for major service. Surface vertical rod mounts on the face of an existing door, which is the retrofit answer when the leaf is not prepped. Rim with a removable mullion is the third route: least prep, but you give up the clear opening. All three latch a pair without a permanent center post except rim, which needs the mullion.
14) Is the Von Duprin 3549A Grade 1, and what standard is that under?
Grade 1 under ANSI A156.3 2008, with the LBL option to the 2014 revision, and UL listed. For an institutional spec that calls for Grade 1 panic hardware on a non-rated egress door, this meets it. What it does not meet is a fire label requirement, since it is not fire rated.
15) What height do I mount a Von Duprin 3549A push bar at?
Device centerline is 39-13/16 inches (1006 mm) from finished floor. That is the number the door prep templates work from, and it is what keeps the bar in the operable range for an accessible opening. Von Duprin publishes separate hollow metal and wood door prep template sets for the series.
16) Can I lock the latches down during business hours on a Von Duprin 3549A?
Hex key dogging comes standard, so you can hold the latches retracted mechanically with a hex wrench for daytime push-pull operation. If you would rather control that with a key, cylinder dogging (CD) is an option, along with CDSI, HDSI, and less dogging (LD) where a facility does not want anyone dogging the door at all. With QEL on this unit you also have the electric route for scheduled unlock.
17) What electrified and monitoring options can I get on this Von Duprin 33/35 Series device besides QEL?
Beyond QEL and CON, the 33/35 Series supports ALK alarm exit kit, CX Chexit delayed egress, EL and HD-EL latch retraction, ESL emergency secure lockdown, LX and LX-RX latch and request-to-exit switching, RX and WP-RX request-to-exit, and SS signal switch. The unit described here is ordered with RX request-to-exit plus QEL plus CON, which is the common combination when an access control head end needs both a release and a confirmed exit signal.
18) Are the mounting fasteners included with a Von Duprin 3549A on a hollow metal door?
Sex bolt mounting is called out for metal doors in the 1-3/4 inch (44 mm) to 2-1/4 inch (57 mm) range, using #425 sex bolts at the end case and #325 at the exit only device. Confirm your leaf thickness falls in that band before you order, because a thicker door needs longer fasteners than the standard set covers.
19) Can an Accentra 7110/7120 top latch replace the top latch on a Von Duprin RX-QEL-3549A-EO-626-36-CON?
No. 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 same style of component for the 7110F. Both are built to their own device family. The Von Duprin RX-QEL-3549A-EO-626-36-CON uses Von Duprin 33/35 Series top and bottom vertical rod strikes, so a top latch replacement is sourced within that series rather than from the Accentra 7110 family. Worth noting for anyone matching fire openings: the Accentra 7110F part and the Von Duprin RX-QEL-3549A-EO-626-36-CON are both non-fire-rated.
20) Does the Von Duprin RX-QEL-3549A-EO-626-36-CON take a rim cylinder housing like the Arrow 16RCR-27 for cylinder dogging?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing for Arrow 24/25 Series devices, keyed into that series. The Von Duprin RX-QEL-3549A-EO-626-36-CON ships with hex key dogging as its dogging configuration, so a cylinder housing is not part of how this device is held down - the hex key does it. A facility standardizing on SFIC keying and wanting a key-operated dog on the door should specify the Von Duprin cylinder dogging option within the 33/35 Series rather than fitting an Arrow housing to it.
21) What finishes does the Von Duprin 3549A come in if I need to match other hardware in the building?
626 satin chrome is the finish on this unit, which is the common commercial match for satin chrome and satin nickel trim. The device is also produced in 605, 606, 612, 619, 622/711, 625, 626AM, 628, 630, 630AM, 643e, 693, and 710, so a property standardizing on oil-rubbed, bright brass, or stainless can be matched across a fleet of openings.
22) I need a replacement top latch for a concealed vertical rod exit device that isn't Von Duprin. What are my options?
Parts do not cross between exit device brands, so match the manufacturer. For Accentra 7110 and 7120 devices there is a top latch replacement component, and a separate one for the fire-rated 7110F. On Falcon 24 Series Monarch devices, the 610061 concealed vertical top rod serves the F-25-C and F-25-CWDC. None of these interchange with Von Duprin 33/35 Series internals.
