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

1) Will the Von Duprin 3549A CVC exit device fit a narrow stile aluminum or hollow metal door?
The 3549A fits door stiles as narrow as 2-1/8 inches (44 mm), which is why it works on narrow stile hollow metal single and double doors. The 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), so the case footprint stays inside that narrow stile. If your stile is under 2-1/8 inches, this is the wrong device.
2) What door sizes does the Von Duprin CD-3549A-EO cover, and can it be cut down for a shorter door?
It is built for a 36 inch door width and the vertical cables adjust for door heights from 82 to 96 inches. So a standard 3-0 x 7-0 opening is covered, and so is a tall 8-foot door, off the same device. Door undercut cannot exceed 3/4 inch (19 mm) or the bottom latch will not reach its strike.
3) Can I use a concealed vertical cable exit device on a pair of doors without a mullion?
Yes. A CVC device like the 3549A latches into a top strike and a bottom strike rather than into the frame edge, so a pair of doors can be secured without a removable mullion. That is the main reason to choose concealed vertical cable over a rim device. If you would rather use rim devices on the pair, you need a mullion instead, such as the Falcon 4023 steel mullion, and the Falcon 525 aluminum mullion stabilizers for that setup.
4) Is the Von Duprin 3549A fire rated?
No. The 3549A is not fire rated. It is UL listed for panic exit hardware and meets ANSI A156.3 - 2008 (LBL option 2014) Grade 1, but it cannot go on a fire door assembly. Fire rated openings also cannot use mechanical dogging, which is part of why cylinder dogging devices like this one are specified on non-rated exits.
5) Does the exit-only 3549A come with outside trim or a lever?
No trim ships with it. EO means exit only, so there is no outside pull, lever or cylinder trim included. From the outside the door is simply secured. If the opening needs outside key access or a lever, you need a trimmed function, not the EO.
6) Is the Falcon 610061 concealed vertical top rod a replacement part for a Von Duprin 3549A cable device?
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 that Falcon platform. The Von Duprin CD-3549A-EO-626-36 is a concealed vertical cable device that actuates its top and bottom latches through 7/32 inch stainless steel cables rather than rigid rods, and it is built on the 33/35 Series. If you are servicing a rod-style Monarch device, the Falcon top rod is the matching part; if you are servicing the 3549A, you want Von Duprin 33/35 Series cable components.
7) I have a pair of doors and do not want concealed vertical hardware in both leaves. What is the alternative to running two 3549A devices?
A removable steel mullion lets you use rim devices on a double door opening instead of vertical latching in each leaf. The Falcon 4023 is a steel mullion made for double door exit device applications. The Von Duprin CD-3549A-EO-626-36 solves the same opening differently: it latches top and bottom into vertical rod top and bottom strikes concealed in the door, which keeps the opening clear of a center post. Choose the mullion route when you want rim devices and can accept a removable post in the opening; choose the 3549A when the opening must stay unobstructed.
8) What does the CD in CD-3549A mean, and what other dogging choices are there?
CD is cylinder dogging: a key-operated cylinder holds the pushpad and latches retracted so the door pushes open freely during business hours, then keys back to latching. It is standard on this device. Von Duprin also offers CDSI, HDSI and LD dogging on the 3549A if you need a different arrangement. Note the dogging cylinder itself is a separate order item.
9) Will the top and bottom latches on the 3549A hold in standard vertical rod strikes?
Top and bottom bolts are deadlocking anti-friction latch bolts with a 1/2 inch (13 mm) throw, engaging a vertical rod top strike and a vertical rod bottom strike. Each latch case measures 5-13/16 x 1-1/4 x 1-7/16 inches (147 x 32 x 37 mm). Because the throw is only 1/2 inch, the strikes have to be set to the Von Duprin prep; the hollow metal and wood door trims and strikes template indexes cover that layout.
10) Do I need to specify handing when ordering the Von Duprin CD-3549A?
It is non-handed as supplied, so one device covers either swing. The exception is the SS (signal switch) option, which makes the device handed. Order the SS with the correct hand.
11) What fasteners come with the 3549A and do I need sex bolts for a metal door?
Metal door fasteners for 1-3/4 inch (44 mm) to 2-1/4 inch (57 mm) door thickness are included. A #425 sex nut and bolt is furnished standard for the end case, and a #325 SNB is furnished standard on exit only devices. So for a standard 1-3/4 inch hollow metal door you have what you need to mount it.
12) Can I get the 3549A electrified for access control or remote release?
Yes. Electrified options on the 3549A include EL and QEL electric latch retraction, HD-EL, EL/ESL, CX, LX and LX-RX switch packages, RX and WP-RX request to exit, ALK alarm kit, SS signal switch, and CON. Mechanical options include AX, GBK, HH, INS-2/INS-4, LBL, PL, PN, SEC, SG, SNB and WH. These are ordered as suffixes on the device, so decide on them before the order goes in rather than retrofitting later.
13) Will the Accentra 7110/7120 top latch parts work on the Von Duprin 3549A?
No. The Accentra 60-7010-0049-999 top latch is a replacement component for Accentra 7110 and 7120 exit devices, and 60-7010-0050-999 is the equivalent component for the 7110F. Neither is interchangeable with the Von Duprin CD-3549A-EO-626-36, which is a 33/35 Series narrow stile device with its own top and bottom latch cases. Match latch components to the device family already on the door.
14) The 3549A is not fire rated. What does that rule out, and are there non-rated peers in the same class?
The Von Duprin CD-3549A-EO-626-36 carries no fire rating, so it is limited to non-rated openings such as exterior entrances and non-rated interior doors. Cylinder dogging, which holds the latches retracted with a key, is itself a non-rated-opening feature. Among comparable exit device components, the Accentra 60-7010-0049-999 and 60-7010-0050-999 top latch parts are likewise non-rated. For a labeled opening you need a fire rated exit device family rather than a cylinder dogging device.
15) Can I use an Arrow SFIC rim housing for the cylinder dogging on the 3549A?
The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing built for the Arrow 24/25 Series. The Von Duprin CD-3549A-EO-626-36 is supplied with CD cylinder dogging, which takes a dogging cylinder specified for the 33/35 Series rather than a rim housing from another device family. Order the dogging cylinder against the Von Duprin platform, and reserve the Arrow housing for 24/25 Series rim applications where an interchangeable core is being keyed into the customer system.
16) Is the Falcon T Series deadlatch an option in place of the 3549A on a narrow stile door?
The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part from the T Series, which is a latching component rather than panic exit hardware. The Von Duprin CD-3549A-EO-626-36 is a Grade 1 exit only panic device for 36 inch wide doors, adjustable from 82 to 96 inches in height. If the opening requires panic hardware for egress, a deadlatch does not satisfy it; use the deadlatch only where a standard latch is acceptable.
17) What finishes is the 3549A available in besides satin chrome?
As ordered it is 626 satin chrome, which is the common commercial match to satin chrome lever trim and closers. Von Duprin also lists 605, 606, 612, 619, 622/711, 625, 626AM, 628, 630, 630AM, 643e, 693 and 710 for this device, so a facility standardizing on dark bronze or anodized aluminum can match existing openings.
18) Can the 3549A go on a wood door as well as hollow metal?
It is engineered for narrow stile hollow metal single and double doors, and the fasteners supplied are metal door fasteners. Von Duprin does publish wood door prep and wood door trims and strikes template indexes for this family, so confirm the prep against those before committing a wood opening.
19) If I go with a mullion instead of the 3549A on an aluminum pair, is there anything else I need?
Mullion installations often call for stabilizing hardware. The Falcon 525 aluminum mullion stabilizers are exit device accessories made for that purpose. The Von Duprin CD-3549A-EO-626-36 avoids the question entirely because it latches into concealed vertical rod top and bottom strikes in the door itself and fits stiles as narrow as 2 1/8 inches, so no center post or stabilizer is involved.
