Von Duprin EL-PA-AX-3549A-EO-3FT-26D-10FT-LBL – Frequently Asked Questions

1) Will the Von Duprin PA-AX-3549A-EO-3F fit a 36 inch wide aluminum storefront door?
Yes, on narrow stile doors. The 3549A device is built for door widths from 2 foot 4 inches up to 3 foot, with a 36 inch device length to cover a 3 foot leaf. If your opening is wider than 3 feet you need a longer device, and if the stile is a wide stile aluminum or hollow metal door this is the wrong family.
2) Can I use this Von Duprin 3549A exit device on a fire rated door?
No. The PA-AX-3549A-EO-3F is not fire rated, so it cannot go on a labeled fire door opening. It also uses hex key dogging, which is not permitted on fire doors. For a fire rated opening you need a fire rated exit device with no mechanical dogging.
3) What does Less Bottom Latch mean on this Von Duprin CVC device, and what do I lose?
Less bottom latch (often called less bottom rod) means the device latches only at the head. The bottom rod and bottom latch are deleted, so nothing hangs down near the threshold to collect dirt or get kicked out of adjustment, which is why it is common on high traffic and door-sweep openings. You give up the second point of latching at the sill. Note the device itself is still catalogued for both vertical rod top strike and vertical rod bottom strike, so the bottom hardware can be added back if the job needs two-point latching.
4) Will the 3/4 inch bolt throw on this device work with my existing top strike?
The latch is a deadlocking type with a 3/4 inch bolt throw, so the top strike has to give at least that depth of engagement and be positioned for a concealed vertical rod latch. If your current opening runs a surface vertical rod or a rim strike, the strike will not carry over; CVC needs the strike set in the head frame.
5) Can a Falcon 610061 concealed vertical top rod be used in place of the Von Duprin PA-AX-3549A-EO-3F?
No. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, so it is a rod component for a Falcon device. The PA-AX-3549A-EO-3F is a 3549A Series electrified latch retraction pushbar assembly, 36 inches long, for a narrow stile concealed vertical cable exit-only opening with a 120 inch door height. If a rod is what failed on a Falcon 25 series device, the 610061 is the part; if the pushbar and latch retraction assembly is what you are replacing on a Von Duprin 3549A, the rod will not serve.
6) Is a fire rated opening a fit for the PA-AX-3549A-EO-3F?
No. The PA-AX-3549A-EO-3F carries no fire rating and is configured with HD hex key dogging, which is a non-fire arrangement since fire doors cannot be held in a dogged state. The Accentra 60-7010-0050-999 top latch is the component for the 7110F, the F in that model designating the fire version of the device. Specify a fire rated exit device for a labeled opening rather than adapting this one.
7) Do I need outside trim with the Von Duprin PA-AX-3549A-EO-3F?
No trim goes with it. This is an exit-only configuration, no outside trim, so the door is egress only from the inside and has no key or lever entry from the pull side. If you need outside access on the same opening, you need a device configured for trim rather than the EO version.
8) How does electric latch retraction differ from just dogging the exit device down?
Dogging holds the pushbar depressed mechanically until somebody goes out with a hex key and undoes it. Electric latch retraction pulls the latch back on a signal from the access control system, so the door can be freed for scheduled hours and re-secured automatically without anyone touching it. The 3549A supports both: it carries HD hex key dogging as well as the electrified retraction, so you can run it either way.
9) Is this a complete new exit device or a replacement part?
It is catalogued by Von Duprin as a replacement part for the 3549A Series CVC device, a pushbar armor accessible electrified latch retraction assembly rather than a boxed complete device with all frame hardware. Order it when you are rebuilding or upgrading an existing 3549A opening.
10) I only need the top latch on my exit device replaced, not the whole pushbar. What else is there?
If the failure is at the latch rather than the bar, a discrete top latch component is the smaller repair. ZenSupply carries the Accentra 7110/7120 exit device top latch replacement component and the Accentra 7110F version for those devices, both non-fire-rated. Those are Accentra parts, though, not Von Duprin, so they go with Accentra 7110/7120 hardware and will not drop into a 3549A.
11) I need to secure a pair of doors. Is a concealed vertical rod device like the 3549A the right choice, or should I use a mullion?
Concealed vertical cable/rod devices latch into the head (and the sill when the bottom latch is fitted), so a pair can be secured with no post between the leaves and the full opening stays clear for carts and gurneys. The alternative is a rim device on each leaf with a removable mullion between them, which is simpler to service but puts a post in the middle of the opening. ZenSupply stocks the Falcon 4023 steel mullion for double door exit device applications and Falcon 525 aluminum mullion stabilizers if you go the mullion route.
12) Is the 3549A device suitable for a hospital or school corridor door with heavy traffic?
It is a commercial-rated device and is used in healthcare, education, office, retail, warehouse and government facilities. The deadlocking latch and electric latch retraction suit high traffic openings where the door needs to free up on a schedule. The one limit to check first: it is not fire rated, so it cannot go on a labeled corridor or stair door.
13) My exit device only needs the top latch replaced - is the PA-AX-3549A-EO-3F overkill?
Likely yes, if the device is an Accentra. The Accentra 60-7010-0049-999 is a top latch replacement component for 7110 and 7120 exit devices, and the 60-7010-0050-999 is the top latch replacement for the 7110F. Those are single latch components. The Von Duprin PA-AX-3549A-EO-3F is a complete 36 inch electrified latch retraction pushbar assembly with a deadlocking latch and 3/4 inch bolt throw, ordered when the pushbar and retraction hardware itself is being replaced or upgraded on a 3549A device rather than a latch alone.
14) Will an Arrow 16RCR-27 rim cylinder housing work with the PA-AX-3549A-EO-3F?
There is nothing for it to key. The Arrow 16RCR-27 is an SFIC rim housing for 6 or 7 pin cores in the 24/25 Series, used where a device takes outside key access. The PA-AX-3549A-EO-3F is configured exit only with no outside trim, so no cylinder is mounted on the pull side. Access from outside on this opening comes from the electrified latch retraction tied into the access control system rather than from a keyed cylinder.
15) What finish does the 3549A pushbar come in?
626 satin chrome is the finish offered, which is the common commercial match for aluminum storefront and other 626 lever and closer hardware already on a building's doors.
16) Can I upgrade the electronics later without replacing the whole exit device?
Yes. The 3549A uses a modular build so the device can be upgraded as access control technology changes, instead of pulling the bar and rods off the door and starting over. That matters on a standardized building where you are adding controlled openings a few at a time.
