    Von Duprin 5547 EO US26D-3 – Frequently Asked Questions

    1) Will the Von Duprin 5547 fit a narrow stile aluminum or metal door?
    The 5547 is built for narrow stile openings, with a 36 inch crossbar device and a 3-3/4 inch projection off the face of the door. Door thickness is 1-3/4 inches. Case dimensions run 7-1/4 x 1-1/4 x 2-1/4 inches for both the hinge stile case and the lock stile case, so measure your stile against that case width before ordering. If your stiles are wide, a wide stile concealed vertical rod device like the Corbin Russwin ED5800 is the right family instead.
    2) Is the Von Duprin 5547 exit device fire rated?
    No. The 5547-3ft is a non-fire-rated device, ANSI/BHMA A156.3 2008 Grade 1 and UL listed for accident hazard (panic) use. If the opening is in a fire rated assembly you need a fire rated CVR device instead: the Adams Rite 3600 Series and the 3900 Series are both fire rated Grade 1 concealed vertical rod devices, and the Sargent 12-MD8613 is a fire rated classroom function CVR. Note those three are all wide stile, so a fire rated narrow stile opening is a different conversation than a straight swap.
    3) Do I have to order the 5547 handed, or can I reverse it in the field?
    Handing is a required selection, LHR or RHR, but the device itself is field reversible for door hand direction. Two things to watch: the lever arm kits and center case kits are handed parts (there are separate left hand reverse and right hand reverse 5547 center cases), so if you are reversing an installed device you may be swapping components rather than just flipping it.
    4) What do I need to specify when ordering a Von Duprin 5547 concealed vertical rod device?
    Six decisions. Handing (LHR or RHR). Trim function: exit only, night latch, night latch with optional pull, lever, lever with blank escutcheon, thumb turn, thumb turn with blank escutcheon, or dummy trim. Lever style if you took a lever function, 06 (the default), 03, 07 or 17. Crossbar: standard, RCB reinforced, or KN knurled. Finish, from eight choices. And whether you want the RX request-to-exit switch and the ES Pullman top latch. The ES top latch is metal doors, less bottom rod only.
    5) Will the 5547 latch into my existing top and bottom strikes?
    Latch throw on the 55 Series is 1/2 inch, which is short compared to a rim device bolt, so the top and bottom strike prep has to be right or the latch will not engage. Concealed vertical rod strikes are not interchangeable with rim strikes. If you are replacing another manufacturer's CVR device, plan on new strikes and new head and threshold prep rather than reusing what is in the frame.
    6) What is the closest narrow stile concealed vertical rod alternative to the Von Duprin 5547 crossbar device?
    The Corbin Russwin ED7800 is the nearest match in form. It is a Grade 1 narrow stile crossbar concealed vertical rod exit device in the ED7000 Series for 1-3/4 inch doors, which is the same crossbar actuation, same stile class, and same door thickness the 5547 is built for. The 5547 is Grade 1, narrow stile, cross bar style, 1-3/4 inch door thickness. The functional difference is trim breadth: the ED7800 is exit only and accepts operator trim, while the 5547 is ordered with dummy, exit only, lever, lever blank escutcheon, night latch, night latch with optional pull, thumb turn, or thumb turn blank escutcheon trim.
    7) Which concealed vertical rod device fits a wide stile hollow metal door instead of a narrow stile one?
    The 5547-3ft is built for narrow stile openings. For wide stile, the Adams Rite 8500 Series is a Grade 1 non fire rated concealed vertical rod exit device for hollow metal doors, and the Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors, exit only and accepting trim. The DORMA 9100 Series is another wide stile Grade 1 option, non fire rated, covering 1-3/4 inch to 2-1/4 inch door thickness.
    8) What concealed vertical rod device covers a door wider than 36 inches?
    The 5547-3ft is a 36 inch device. For a wider leaf, the Falcon 1990EO is a 44 inch narrow stile concealed vertical rod exit device, exit only, Grade 1, for 1-3/4 inch doors, and the CRL Jackson 1085 Series is a 48 inch non handed concealed vertical rod panic device in exit only function for wide stile. Device length is measured against the door leaf width, so confirm the leaf before choosing between the 36 inch and the longer devices.
    9) Which concealed vertical rod exit device suits an aluminum storefront door?
    The Adams Rite 8600 Series is a narrow stile concealed vertical rod exit device specified for aluminum doors, Grade 1 and non fire rated. The Von Duprin 5547-3ft is a narrow stile device built for metal doors with a screw pack for 1-1/4 inch and 2-1/4 inch thick metal and wood doors. For a storefront where stile width varies, the CRL Jackson 1285 push pad concealed vertical rod device is listed for narrow, medium or wide stile.
    10) Should I use a concealed vertical rod device or a rim device on a pair of doors?
    A concealed vertical rod device like the 5547 latches at the head and the threshold, so a pair of doors can be secured with no center mullion and the rods run inside the door leaf where nobody can hit them or paint them. That is why it gets specified on storefront and lobby pairs. The trade-off is service access: the rods and latches are inside the door, so the 55 Series carries a full set of serviceable rod kits, connectors and latch parts for exactly that reason. If you can live with a mullion or a surface rod, those are simpler to adjust. Von Duprin's 55 Series also offers a rim (27) and a mortise (75) version if the opening suits one of those better.
    11) Does hex key dogging on the Von Duprin 5547 let me prop the door open during business hours?
    Yes. Hex key dogging holds the latch retracted so the door pushes open freely, which is what you want on a retail entrance or a school corridor during the day. It takes the special hex key (Von Duprin 103866) to set and release, so it is not something the public can defeat. One caution: dogging is only permitted on non-fire-rated openings, and the 5547 is a non-fire-rated device, which is consistent. Never dog a fire door.
    12) What fasteners come with the Von Duprin 5547, and do I need anything else?
    A screw pack is included covering 1-1/4 inch and 2-1/4 inch thick metal and wood doors. What is not in the box is the trim: if you ordered a lever, night latch or thumb turn function you are specifying that trim separately, and any night latch or keyed function needs a cylinder, which is not supplied with the device.
    13) I need a card reader to release this door. Can the Von Duprin 5547 be electrified?
    The 55 Series supports the E8875 electrified trim for access control or fire alarm integration, and the RX request-to-exit switch is an orderable option on the device for door position and egress monitoring. Specify RX at order time; it is a device option, not a field add. If your integrator wants to know when the door is used versus when it is unlocked, RX gives you the first and the electrified trim gives you the second.
    14) What is a Grade 1 exit device and does my school or hospital need one?
    Grade 1 is the top ANSI/BHMA durability tier for exit devices, and the 5547 carries ANSI/BHMA A156.3 2008 Grade 1 with UL listing for accident hazard use plus ANSI/UL 305 and CAN/ULC-S132 panic listings. For an institutional opening (school, hospital, government building) Grade 1 is generally what the spec calls for, and the certification is what an inspector or a spec writer will ask you to document. Grade 2 devices exist for lighter traffic but will not satisfy a Grade 1 spec.
    15) My doors are aluminum storefront, not hollow metal. Is the Von Duprin 5547 still the right device?
    The 5547 is a narrow stile device for single or double metal doors, and narrow stile is the aluminum storefront profile, so it is in the right family. Confirm your stile can take the 7-1/4 x 1-1/4 x 2-1/4 inch case and that the door is 1-3/4 inches thick. If it is a true aluminum storefront leaf and you want a device built specifically for that, the Adams Rite 8600 Series is a narrow stile concealed vertical rod device for aluminum doors.
    16) Can I get the Von Duprin 5547 as less bottom rod to avoid a threshold latch?
    Less bottom rod applies here through the ES Pullman top latch option, which is offered for metal doors on less-bottom-rod configurations only. LBR is what you want where floor dirt, carpet or a wet threshold would foul a bottom latch, common in kitchens, entrances and healthcare corridors. Bottom rod kits (050036 and 050096) remain available if you are servicing a full-rod device instead.
    17) Is there a simpler exit only concealed vertical rod device if no outside trim is needed?
    Yes. The Falcon 24-C Series is a Grade 1 36 inch narrow stile concealed vertical rod exit device in exit only function for 1-3/4 inch doors, matching the 5547-3ft on 36 inch size, narrow stile, and 1-3/4 inch door thickness without the trim options. The Falcon 1690EO is a 3 ft narrow stile exit only device on the same 1-3/4 inch door thickness. The 5547 covers exit only as one of its trim functions, so the comparison is whether the opening will ever need lever, night latch, or thumb turn trim added later.
    18) What is the difference between the Von Duprin 5547 and a push pad concealed vertical rod device like the DORMA 9600BB?
    Both are Grade 1 narrow stile non fire rated concealed vertical rod devices at 36 inches, but the actuation differs. The 5547-3ft is a cross bar device; the DORMA 9600BB Series is a narrow stile push pad, heavy duty, covering 1-3/4 inch to 2-1/4 inch door thickness. Buyers standardizing a building on one touch pattern usually pick one or the other and stay with it, since the crossbar and the push pad look and feel different on the door.
    19) Can the Falcon 1491DT be used in place of a Von Duprin 5547?
    Not as an egress device. The Falcon 1491DT is a dummy trim narrow stile concealed vertical rod device with a 9970 pull, 42 inches, in dummy function for 1-3/4 inch doors. Dummy function means it does not latch or release, so it belongs on the inactive leaf of a pair, not on the egress leaf. The 5547-3ft does offer dummy trim among its trim functions, so a matched pair of Von Duprin devices is the usual way to keep the appearance consistent across both leaves.
    20) Is there a non-handed concealed vertical rod device instead of specifying hand?
    The 5547-3ft is field reversible for hand, so one device covers either swing. If a fully non handed device is preferred, the BEST Precision 2601 Series is a narrow stile exit only concealed vertical rod device that is non handed, and the CRL Jackson 1085 Series is a 48 inch non handed concealed vertical rod panic device. For a wide stile wood door, the BEST Precision 2701 Series is reversible.
    21) Which comparable concealed vertical rod device also offers hex dogging on a 36 inch metal door?
    The Sargent MD8613F-LTRIM is a Grade 1 heavy duty concealed vertical rod exit device for metal doors at 36 inches by 84 inches with hex dogging, from the 80 Series. The Von Duprin 5547-3ft is also a 36 inch Grade 1 device with hex key dogging. Both hold the latch retracted for daytime traffic, so the choice comes down to which manufacturer the rest of the building is standardized on.
    22) Which concealed vertical rod device fits a wood door?
    The BEST Precision 2701 Series is a wide stile reversible concealed vertical rod exit device for wood doors, and the BEST Precision 2801 Series is a wide stile concealed vertical rod device in the 2800 Series. The Von Duprin 5547-3ft is a narrow stile device and ships with a screw pack for 1-1/4 inch and 2-1/4 inch thick metal and wood doors, so verify the stile width on the wood leaf before choosing between them.
    23) What finishes does the Von Duprin 55 Series crossbar exit device come in for matching other doors in my building?
    Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 643E aged bronze, and 693 black. If you are standardizing across a facility, 626 satin chrome and 630-family satin finishes are the usual commercial default, and matching the number rather than the description is what keeps a fleet of doors consistent.
    24) Can I get a knurled crossbar on this exit device for a hazardous door?
    Yes, KN knurling is an orderable crossbar option on the 5547. Knurling is the tactile warning texture that tells someone who cannot see the sign that the door leads somewhere hazardous, and it gets specified on mechanical rooms, chemical storage and loading areas. RCB reinforced crossbar is the other upgrade if the concern is abuse rather than warning.
    25) Can I convert an existing 55 Series exit device to night latch function?
    Yes. Von Duprin catalogs the 050105 NL conversion kit for 55 Series exit devices, along with the 050184 55NL center case kit and handed NL cams (050355 right hand, 050356 left hand). Night latch is also orderable on the device from the factory as NL, or NL-OP if you want the cylinder assembly with an optional pull.
