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

1) Will the Von Duprin 3549A-EO fit a narrow stile aluminum or hollow metal door?
The 3549A-EO is built for narrow stile openings and mounts on stiles as narrow as 2 1/8 inches (44 mm). It is intended for hollow metal single and double doors in an exit-only setup. If your stile measures less than 2 1/8 inches, this device will not land on it and you need a different mounting approach.
2) What door sizes does the 3549A-EO concealed vertical cable device cover, and can it be cut down for a shorter door?
The device is sized for a 36 inch wide door and adjusts up to 96 inches in height, with a stated coverage range of 82 to 96 inches. Device lengths are offered for door sizes from 2 feet up to 4 feet (610 mm to 1219 mm). So a standard 3070 or a tall 3080 opening is covered without special ordering; height adjustment is part of the install, not a separate part number.
3) Can I use the Von Duprin 3549A-EO on a fire rated door?
No. The 3549A-EO is panic hardware only, not fire exit hardware, and it carries no fire rating. It is UL listed for panic exit hardware and meets ANSI A156.3 - 2008 (LBL option 2014) Grade 1. On a labeled fire door you need a fire exit device instead, and dogging is not permitted there either, which is another reason this hex dogging model does not belong on a rated opening.
4) Does an exit-only device like the 3549A-EO mean there is no way in from the outside?
Correct. Exit only means no outside trim: the device releases the door from the inside and there is no lever, pull, or cylinder on the pull side to retract the latches. Use it on egress-only openings, stair discharge, or rear service doors. If people need to get back in through that door, you need a device with outside trim rather than the EO configuration.
5) Will the 3549A-EO latch into my existing top and bottom strikes?
Top and bottom bolts throw 1/2 inch (13 mm) and are a deadlocking anti-friction design, and the device is classified for a vertical rod top strike and a vertical rod bottom strike. If your opening already has vertical rod strikes at the head and threshold, the geometry is the same family; measure the strike pocket depth against that 1/2 inch throw. Devices that latch only into the frame head, or into a mullion, use different strike hardware entirely.
6) Do I need to specify a hand when ordering the 3549A concealed vertical cable exit device?
No handing to specify. The concealed vertical cable device is non-handed, with one exception: if you order the SS signal switch option, handing does matter. Everything else, including the electrified latch retraction and request-to-exit options, goes on either hand of door.
7) What is the difference between a concealed vertical cable exit device and a concealed vertical rod exit device?
The Von Duprin 3549A-EO is a narrow stile concealed vertical cable device: stainless steel cables run inside the door to the top and bottom latches instead of rigid rods, and the device is non-handed with hex key dogging standard. A rod-based concealed vertical system uses a rigid rod for the same job, and the rod is a serviceable part specific to its device family - the Falcon 610061 is a 24 Series Monarch concealed vertical top rod made for the F-25-C and F-25-CWDC devices. The practical consequence is that the two families are not interchangeable at the concealed hardware level: cable devices are serviced with cable assemblies and rod devices with rods matched to that device, so identify which system is already in the door before ordering internal parts.
8) For a pair of doors, is it better to put a vertical exit device on both leaves or use a removable mullion?
Those are two different ways to secure a double opening. The Von Duprin 3549A-EO handles the pair by putting a concealed vertical cable device in each leaf, latching top and bottom - it uses a vertical rod top strike and vertical rod bottom strike, it is exit only with no outside trim, and it fits stiles as narrow as 2 1/8 inches. The mullion approach instead puts a vertical post between the leaves so each door can carry a rim device latching into the mullion: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are used to steady mullion installations. Choose by the opening: a mullion occupies the clear width between the leaves, while the concealed vertical arrangement leaves the opening clear but requires door prep top and bottom.
9) Is the 3549A-EO an option for a fire rated opening, or do I need different hardware?
The Von Duprin 3549A-EO is not fire rated, and the same is true of the Accentra 7110/7120 top latch replacement component 60-7010-0049-999. Non-fire-rated panic hardware is the right choice on egress openings that carry no fire label - the 3549A-EO is UL listed for panic exit hardware and certified to ANSI A156.3 Grade 1 for that duty, with hex key dogging standard so the door can be held in a dogged, push-pull state during business hours. A labeled fire door assembly needs fire exit hardware, which cannot be dogged; if the frame carries a fire label, specify a fire rated device family instead of adapting a non-rated one.
10) Can I hold the doors unlatched during business hours with a 3549A-EO?
Yes, hex key dogging comes standard, so you can dog the pushpad down with a hex wrench and let the door push-pull freely through the day. If you would rather control that with a key, order cylinder dogging (CD). There are indicator versions too, CDSI for cylinder dogging with a security indicator and HDSI for hex dogging with an indicator, and LD if you want the device supplied with no dogging at all.
11) Can the 3549A-EO be tied into an access control system or card reader?
It supports the full Von Duprin electrified range: electric latch retraction (EL) and quiet electric latch retraction (QEL) for card reader release, request to exit (RX) and signal switch (SS) for monitoring, emergency secure lockdown (ESL), Chexit delayed egress (CX), the ALK alarm exit kit, and Allegion Connect (CON). Those are ordering options built into the device, not field add-ons, so specify them with the order. Note that choosing SS makes the device handed.
12) Why choose a concealed vertical cable exit device instead of surface vertical rod or a rim device with a mullion?
Concealed vertical cable puts the latching hardware inside the door, so nothing hangs on the face to catch carts or get kicked, and the pair of doors latches at head and threshold with no center mullion in the opening. That matters where you need the full clear width for equipment or gurneys. A rim device with a removable mullion is the cheaper route and easier to service, but it leaves a post in the middle of the opening. Surface vertical rod is the middle ground: exposed rods, but serviceable without opening up the door. The concealed route also requires a door prepped for it, which is why this is a hollow metal narrow stile device rather than a retrofit onto any door.
13) What fasteners come with the Von Duprin 3549A-EO and what door thickness do they cover?
Sex bolts (SNB) are included, sized for 1 3/4 inch (44 mm) to 2 1/4 inch (57 mm) metal doors. The #425 SNB is furnished standard for the end case and the #325 SNB is furnished standard for the exit-only configuration. That range covers standard 1 3/4 inch commercial hollow metal without buying anything extra.
14) What height should the pushbar be mounted at, and how much space does the center case take up on the door?
Device centerline from finished floor is 39 13/16 inches (1006 mm). 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). Use the 1 9/16 inch case depth when you are checking clearance against a door closer arm, a stop, or a wall the door swings against.
15) Can I skip the bottom latch on a 3549A concealed vertical device where the floor is uneven?
Yes, order the LBL less bottom latch option. That is the usual call where the threshold is out of level, where a floor strike would be a trip hazard, or where you are trying to avoid a dirt trap at the sill. The ANSI A156.3 - 2008 Grade 1 certification covers the LBL option under the 2014 revision.
16) I need a mullion for a pair of doors instead of a concealed vertical device. What does ZenSupply carry?
If you would rather run rim devices against a center post, the Falcon 4023 steel mullion handles double door exit device applications, and Falcon 525 aluminum mullion stabilizers go with it. That is a different approach than the 3549A-EO, which latches at the head and threshold and leaves the opening clear with no post in the middle. Choose the mullion route when you want simpler service and cheaper hardware; choose concealed vertical when the full clear opening width matters.
17) I just need a replacement top rod or latch for a concealed vertical exit device, not a whole new device. What are the options?
Depends on the brand already on the door. For a Falcon 24 Series Monarch concealed vertical device, the Falcon 610061 top rod fits the F-25-C and F-25-CWDC. For Accentra 7110 and 7120 exit devices there is a top latch replacement component, with a separate version for the 7110F. Those are components for those devices specifically and will not go into a Von Duprin 3549A, which is a complete concealed vertical cable device rather than a rod-and-latch retrofit part.
18) Is the Von Duprin 3549A-EO rated for a high traffic entrance in a school or hospital?
It is certified to ANSI A156.3 - 2008 (LBL option 2014) Grade 1, the top commercial grade for exit devices, and it is a commercial-only product. Grade 1 is the tier institutional specs typically call for on high-cycle openings. It is not fire rated, so keep it off labeled openings and put it on your egress and exterior doors instead.
19) Do I need a rim cylinder housing to go with an exit only concealed vertical device?
No. The Von Duprin 3549A-EO is configured exit only, meaning there is no outside trim and no outside key cylinder to operate it, and it ships with hex key dogging as its standard dogging method. A rim cylinder housing such as the Arrow 16RCR-27, a 6/7-pin SFIC rim housing in the 24/25 Series family, belongs to an installation where a small format interchangeable core operates trim or cylinder dogging from outside. If the opening needs key access or cylinder dogging rather than hex dogging, that is a different device configuration, not an accessory added to an exit only unit - the 3549A family lists cylinder dogging (CD) and cylinder dogging with security indicator (CDSI) as ordering options.
20) My exit device only has a bad top latch - do I have to replace the whole device?
Not necessarily, but the repair path depends on which device is in the door. Top latch components are sold as replacement parts within a device family: the Accentra 60-7010-0049-999 is a top latch replacement component for 7110 and 7120 exit devices, and the Accentra 60-7010-0050-999 is the top latch replacement component for the 7110F. Those fit their own devices only. The Von Duprin 3549A-EO is a complete narrow stile concealed vertical cable device with a deadlocking anti-friction top and bottom bolt of 1/2 inch throw, adjustable to a 96 inch door height for a 36 inch wide door - it is the answer when the whole concealed vertical assembly is being replaced or the door is being newly prepped, rather than when one latch on an existing device has failed.
21) Can a deadlatch part be used instead of a vertical exit device on a narrow stile aluminum or hollow metal door?
They solve different problems. A deadlatch such as the Falcon 23981160, a T Series 2-3/8 inch square corner deadlatch replacement part, is a latch component serviced within a T Series latch installation and does not provide panic egress. The Von Duprin 3549A-EO is UL listed panic exit hardware certified to ANSI A156.3 Grade 1, with a full-width push pad that releases top and bottom bolts on a narrow stile door. If the opening is required to have panic hardware for egress, a deadlatch component will not satisfy that requirement; if the opening is a standard latched door with no egress hardware requirement, the exit device is more hardware than the door needs.
22) What finishes does the Von Duprin 3549A-EO come in?
Two finishes: satin chrome and dark bronze anodized. Dark bronze anodized is the one that matches dark aluminum storefront and bronze-anodized frames; satin chrome is the general commercial finish that reads closest to the brushed stainless on adjacent openings. If you are standardizing a building, pick the one that matches the frame, not the other doors' hardware.
23) What are the vertical cables made of, and will they hold up in an exterior or wash-down opening?
The vertical cables are stainless steel, 7/32 inch (6 mm) diameter, chosen for corrosion resistance in commercial service. For exterior openings there are matching options on the order: HH hurricane, WH weep holes to drain the door, and SEC security screws. The bolts themselves are deadlocking anti-friction, which keeps them working against a door that has settled or is being pushed on.
24) Can the 3549A-EO be used on a glass door or a door with a glass light kit?
There is a glass bead kit (GBK) option for doors with vision lights, and Insulclad kits for 1/2 inch and 1/4 inch panels (INS-2 and INS-4) where the door has an insulated panel. Those are specified with the order. The base device is still a narrow stile hollow metal application, fitting stiles down to 2 1/8 inches (44 mm), so confirm the stile on a glass-front door before you commit.
