Von Duprin AX-3549A-EO-3FT-26D-8FT-LBL – Frequently Asked Questions

1) Will the Von Duprin AX-35A fit a 36 inch by 96 inch narrow stile aluminum door?
That is exactly the opening it is built for. The AX-35A concealed vertical cable device is sized for a 36 inch wide by 96 inch tall door and uses a narrow stile push pad, so it suits aluminum and glass front narrow stile doors rather than wide stile hollow metal. If your door is a different width or height, you need a different device size.
2) Does the AX-35A have outside trim or a way to get back in from the outside?
No outside trim. The AX-35A is an exit only device, meaning it releases from the push pad on the inside and there is no lever, pull, or cylinder on the outside to retract the latch. If you need controlled re-entry from the exterior, specify a trim-prepped function instead of exit only.
3) Does the AX-35A come with a bottom latch?
It ships less bottom latch. The device is configured as the 3549A-EO CVC with a top latch engaging the vertical rod top strike, and the bottom strike is listed for the configuration but the bottom latch itself is not included. Plan on ordering the bottom latch separately if your opening needs two point latching.
4) I have a pair of doors with no mullion. Does the AX-35A work there, or do I need a mullion?
A concealed vertical cable device latches into the frame head and the threshold rather than into the opposite leaf, so it secures a pair with a clear opening and no center post. If you would rather run rim devices on both leaves, you need a mullion between them, such as the Falcon 4023 steel mullion, and Falcon 525 aluminum mullion stabilizers are available for that setup.
5) Can the Von Duprin AX-35A be used on a fire-rated opening?
No. The AX-35A carries a fire rating of No, so it is a panic device for non-fire-rated egress openings only. On a fire-rated pair, the exit hardware and the mullion both have to be fire-labeled; a steel mullion such as the Falcon 4023, built for double door exit device applications, is the type of component used to keep a double opening latched, but the AX-35A itself should not be specified where a fire label is required. For a fire opening, order the fire-labeled version of the device family instead.
6) I just need to replace a concealed vertical top rod - is the AX-35A what I order?
No. The AX-35A is a complete Grade 1 narrow stile concealed vertical cable device in an exit only, no outside trim function. If the existing device is sound and only the top rod has failed, you want the rod component for that device family - for example, the Falcon 610061 is a 24 Series Monarch concealed vertical top rod made for the F-25-C and F-25-CWDC exit devices. Match the rod to the device brand and series already on the door; order the AX-35A only when the whole device is being replaced.
7) What does concealed vertical cable mean compared with a surface vertical rod exit device?
A concealed vertical cable device runs its latching linkage inside the door instead of on the face, so nothing shows on the door surface and there is no exposed rod to get kicked or bent. It latches at a top strike and a bottom strike. Surface vertical rod is the option when the door is not prepped for concealed hardware, since concealed cable requires a door built or cut for it. A rim device with a removable mullion is the other route on a pair, but it puts a post between the leaves.
8) Can I hold the AX-35A push pad down so the door stays unlatched during business hours?
Yes. Hex dogging is built in, so a hex key depresses and holds the push pad, leaving the latch retracted for push-pull operation while the building is open. Because the device is not fire rated, dogging is permitted here.
9) Is the AX-35A heavy duty enough for a school or hospital main entrance?
It is a Grade 1 commercial device with a metal construction and a deadlocking latch, which is the top durability tier for exit hardware and the usual spec for high traffic entrances. The AX designation is the accessible version, and the fluid damper quiets the push pad return, which is why these get spec'd in schools, healthcare and offices.
10) I need a replacement concealed vertical top rod for an existing exit device, not a whole new one. What are my options?
If the device on the door is a Falcon 24 Series Monarch, the Falcon 610061 concealed vertical top rod is the component made for the F-25-C and F-25-CWDC devices. Top latch components are also stocked for the Accentra 7110/7120 devices. The Von Duprin AX-35A is a complete 3549A Series device rather than a single replacement rod, so it is the answer when you are replacing the whole assembly.
11) For a pair of doors, is a mullion an alternative to putting an AX-35A on each leaf?
They solve different problems. The AX-35A is a concealed vertical cable device that latches top and bottom into vertical rod top and bottom strikes, so each leaf latches into the frame and header on its own and no mullion is needed. A removable steel mullion such as the Falcon 4023 instead gives a pair of doors a fixed vertical strike surface so rim devices can be used on both leaves. If you want a clean opening with nothing between the leaves, the concealed vertical cable route is the one that keeps the opening clear; if you prefer rim devices, the mullion approach is the one to price.
12) Does ordering the AX-35A get me a cylinder for outside access?
No. The AX-35A is configured exit only with no outside trim, so it pushes to exit and there is no keyed outside operation included. Outside key access is a separate trim and cylinder decision - a small format interchangeable core housing such as the Arrow 16RCR-27 6/7-pin SFIC rim housing is the kind of component that pairs with rim trim on a keyed opening, not with an exit only concealed vertical cable device. If the opening needs key entry from outside, specify a keyed-trim version of the device rather than adding a cylinder to this one.
13) What finishes does the Von Duprin AX-35A come in?
Three finishes: 626 satin chrome, 628 aluminum, and 710 dark bronze anodized. On aluminum storefront, 628 usually matches clear anodized frames and 710 matches dark bronze anodized frames, which makes matching existing openings in a building straightforward.
14) What makes the AX-35A different from a standard narrow stile exit device when accessibility is a concern?
The AX-35A is built as an AX-Accessible device and uses The Quiet One fluid damper, so push pad operation is smooth and quiet - useful in schools, healthcare and offices where noise and accessible operating force both matter. It is Grade 1, all metal, with a deadlocking latch and HD hex dogging for holding the latch retracted during business hours. Replacement latch components such as the Accentra 7110/7120 top latch are non-fire-rated service parts for other device lines and do not change the accessibility characteristics of an opening.
