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

1) Will a Von Duprin 3549A concealed vertical cable exit device fit a narrow stile aluminum or glass door?
Yes, down to a 2-1/8 inch (44 mm) stile. That is the point of the 3549A: the mechanism case is sized for narrow stile openings where a wide stile device would overhang the glass stop. The vertical cables are 7/32 inch (6 mm) stainless steel and run concealed inside the door, so nothing is exposed on the face. If your stile measures under 2-1/8 inches, this device will not land on it and you need a rim device on a different door.
2) What door size does the RX-QELA-3549A-EO cover, and can it be cut down for a narrower opening?
It is built for a 36 inch wide door and a door height range of 82 to 96 inches. Von Duprin states the device fits doors from 2 to 4 feet (610 mm to 1219 mm) in width, so the 36 inch device is sized and cut for that opening. Order to the actual door width you are hanging it on rather than assuming one length covers the building.
3) Can the 3549A CVC exit device be used on a fire rated door?
No. The RX-QELA-3549A-EO is not fire rated, and electric latch retraction devices generally cannot be dogged or held retracted on a fire opening anyway. For a labeled opening you need a fire rated exit device with fire rated top and bottom latching, not this one.
4) Does the Von Duprin 3549A concealed vertical cable device need to be ordered handed?
The concealed vertical cable design installs non-handed, with one exception: when the signal switch is used, handing matters. This unit ships with RX (request to exit), which is a switch, so confirm the door hand before you order rather than treating it as a field-reversible device.
5) Will the 3549A latch into my existing top and bottom strikes?
The device latches with a deadlocking anti-friction latch bolt top and bottom, each with a 1/2 inch (13 mm) throw, and it uses vertical rod top and bottom strikes. A 1/2 inch throw is short, so the head strike and the threshold strike have to be set at the right depth and in line with the cable path. On a retrofit, plan on the Von Duprin strikes that go with the device rather than reusing whatever is in the frame.
6) Does Exit Only mean there is no way to get back in through this door?
Correct. EO means no outside trim, so the door is egress only from the mechanical side. Entry happens electrically: the QEL retracts the latches on a valid credential, and the door pulls open. If you want a key override or a lever on the outside, you need the same device ordered with trim instead of the EO configuration.
7) Is this Von Duprin exit device Grade 1 and UL listed for a high traffic commercial entrance?
It is UL listed and meets ANSI A156.3 2008 (with LBL option 2014) Grade 1. Grade 1 is the top commercial durability tier in that standard and is what most institutional and government specs call for on a main entrance. The device is catalogued commercial, not residential.
8) Is a Falcon 610061 concealed vertical top rod a substitute for the cable in a Von Duprin RX-QELA-3549A-EO-626-36?
No. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod made for the F-25-C and F-25-CWDC exit devices, so it belongs to a rod-driven vertical system. The Von Duprin RX-QELA-3549A-EO-626-36 is a concealed vertical cable device in the 33/35 Series, where the top and bottom latches are driven by 7/32 inch stainless steel cable rather than a rigid rod. The two drive systems are not interchangeable, and a top rod cut for a Falcon 245 Series device will not pick up the cable run in the Von Duprin narrow stile chassis. If you are servicing an F-25-C or F-25-CWDC opening, the 610061 is the matching top rod; if you are servicing the 33/35 Series cable device, stay within the Von Duprin cable parts.
9) What do I use to make a pair of doors work if I do not want concealed vertical cable devices on both leaves?
A removable steel mullion is the usual alternative. The Falcon 4023 is a steel mullion built for double door exit device applications, and it lets you hang rim devices on both leaves against a common vertical post instead of running vertical hardware in each door. The Von Duprin RX-QELA-3549A-EO-626-36 takes the other approach: it is a concealed vertical cable device for a 36 inch wide door, latching to a vertical rod top strike and a vertical rod bottom strike so the opening stays clear with no post in the middle. Choose the mullion route when you can accept the post in the doorway; choose the concealed vertical cable route when the opening has to stay unobstructed for carts, gurneys, or wide freight.
10) The opening needs a fire rated device. Is the Von Duprin RX-QELA-3549A-EO-626-36 the right pick?
No. The Von Duprin RX-QELA-3549A-EO-626-36 is a non fire rated Grade 1 concealed vertical cable device for commercial openings, so a labeled door assembly calls for a fire rated device instead. The same is true of the Accentra top latch replacement components 60-7010-0049-999 and 60-7010-0050-999, which are also non fire rated. Confirm the label on the door and frame first, then select a device carrying the matching fire rating; use the RX-QELA-3549A-EO-626-36 on non labeled commercial egress openings where quiet electric latch retraction and request to exit monitoring are what the access control system needs.
11) What does QEL do on a Von Duprin exit device, and how is it different from standard EL?
QEL is Quiet Electric Latch Retraction. The motor pulls the top and bottom latches in on an access control signal so the door can be pushed or pulled free without noise, which is why it gets specified in libraries, healthcare corridors, and offices where the clack of a standard EL solenoid is a complaint. Standard EL does the same job louder. Von Duprin offers both, along with HD-EL, on this platform, so if noise is not a concern the plain EL configuration is the other route.
12) What is RX on an exit device and do I still need a separate request to exit sensor?
RX is an integrated request to exit switch in the device itself. Pushing the touchpad signals the access control panel that the egress was legitimate, so the door forced or door held alarm is suppressed. With RX built into the 3549A you are not adding a ceiling mounted motion REX over the door for that function. Run the RX contacts back to the panel along with the QEL power.
13) Can I hold the 3549A unlocked during business hours, and what dogging options are there?
Hex key dogging comes standard, which lets you hold the touchpad depressed and the latches retracted for daytime free passage. If you do not want a hex key floating around the building, Von Duprin also offers cylinder dogging (CD), cylinder dogging with security indicator (CDSI), hex dogging with security indicator (HDSI), and less dogging (LD). The security indicator versions show at a glance whether the device is dogged, which is what facilities crews on a nightly walk usually want.
14) Should I use a concealed vertical cable device or a rim device with a mullion on a pair of doors?
A concealed vertical cable device latches at the head and the threshold, so a pair of doors secures with no center mullion and the opening stays fully clear. That is why CVC gets specified on glass fronts and main entries. A rim device is the simpler and cheaper route, but on a pair it needs a removable mullion in the middle, which you take out for wide loads and store somewhere. If you go the mullion route, we stock the Falcon 4023 steel mullion for double door exit device applications, and Falcon 525 aluminum mullion stabilizers.
15) What other electrified options can this Von Duprin 33/35 Series device be ordered with?
Beyond QEL and RX, the platform supports ALK (alarm exit kit), CX (Chexit delayed exit), EL, ESL (emergency secure lockdown), HD-EL, LX, LX-RX, WP-RX, RX-LC, LX-LC, LX-RX-LC, SS (signal switch), and CON (Allegion Connect). LX is a latch monitoring switch rather than a request to exit switch, so if the panel needs to know the latch actually threw, LX-RX is the combination to specify, not RX alone.
16) What do I need to order alongside a QEL exit device to make it work?
QEL is motor driven, so it needs a power supply sized for the device and wiring from that supply into the door, typically through an electric power transfer hinge or a door loop. The RX contacts also need a run back to the access control panel. The device itself is exit only with no outside trim, so nothing on the pull side is included and nothing is needed there unless you are adding a reader.
17) I already have a mullion on my pair of doors and it is flexing. Do I need a different exit device?
Not necessarily. The Falcon 525 aluminum mullion stabilizers are made to steady a mullion in an exit device application, which addresses movement at the post rather than at the device. That is a separate repair path from replacing the doors with a concealed vertical cable device such as the Von Duprin RX-QELA-3549A-EO-626-36, which latches to a top strike and a bottom strike in the frame and header and carries no center post at all. Stabilizers keep an existing mullion opening as it is; the concealed vertical cable device is the choice when you are removing the mullion from the opening entirely.
18) Can I fix a failing top latch with a replacement component instead of buying a whole exit device?
It depends on which device is in the door. Accentra publishes top latch replacement components for its own exit devices, such as 60-7010-0049-999 for the 7110 and 7120 and 60-7010-0050-999 for the 7110F, so an Accentra opening can often be repaired at the latch. Those components are brand and series specific and do not fit the Von Duprin RX-QELA-3549A-EO-626-36, which is a 33/35 Series concealed vertical cable device with top and bottom deadlocking anti-friction latch bolts driven off the cable run. Match the replacement component to the device family already installed before ordering.
19) Do I need a rim cylinder housing like the Arrow 16RCR-27 to complete a Von Duprin RX-QELA-3549A-EO-626-36?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing from the Arrow 24/25 Series, used where a rim device or trim takes a small format interchangeable core. The Von Duprin RX-QELA-3549A-EO-626-36 is an Exit Only configuration, so it takes no outside trim and needs no cylinder to operate, and it ships with hex key dogging as the standard dogging method rather than cylinder dogging. Order a cylinder only if you move to a cylinder dogging or keyed trim configuration, and match it to the Von Duprin device rather than to an Arrow housing.
20) I need a replacement top latch or vertical rod for an existing exit device, not a whole new one. What is available?
The RX-QELA-3549A-EO is a complete device, not a service part. For component level repairs on other brands we carry the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, and Accentra top latch replacement components for the 7110/7120 and the 7110F. Match the replacement part to the device family already on the door, since latches and rods do not cross between manufacturers.
21) What finish does the RX-QELA-3549A-EO-626 come in, and will it match the rest of my door hardware?
626, satin chrome. That is the most common commercial finish in North America and it lines up with satin chrome closers, pulls, and cylinders on adjacent openings, so on a building already standardized on 626 this drops straight in without an odd door.
