Von Duprin 5547L-626-36-LHR-LESS TRIM – Frequently Asked Questions

1) Will the Von Duprin 5547L-3 fit a narrow stile aluminum or metal door?
Yes. The 5547L-3 is a narrow stile device, which is what lets it mount on the slim lock stile of a storefront-style metal door where a wide stile chassis has no room. Both the hinge stile case and lock stile case measure 7-1/4 x 1-1/4 x 2-1/4 inches, and the crossbar projects 3-3/4 inches off the face of the door, so allow that clearance in a vestibule or tight corridor.
2) Do I have to order the 5547L-3 handed for a left or right hand door?
No, handing is not part of the order. Door hand direction on the 5547L-3 is field reversible, so one device covers both hands and you can set it on site. That matters if you are buying spares for a building with openings swinging both ways.
3) Is a concealed vertical rod device the right choice for a pair of doors without a mullion?
Yes, that is the main reason to use one. A concealed vertical rod device latches at the head and the sill rather than into a strike on the frame jamb, so a pair of doors can be secured without a center mullion and you get the full clear opening width. The rods run inside the door, so nothing is exposed on the face. If you want the hardware hidden, this is the type; if you would accept rods on the surface or a removable mullion with a rim device, those are simpler to service.
4) Will the 5547L-3 latch into an existing top and bottom strike?
Latch throw on the 5547L-3 is 1/2 inch, so the top strike at the head and the bottom strike or floor prep have to engage within that depth. If the existing prep was cut for a device with a deeper throw or a different rod centerline, plan on new strikes rather than reusing what is in the frame.
5) What is a comparable narrow stile concealed vertical rod exit device if the Von Duprin 5547L-3 is not the right fit?
Several narrow stile concealed vertical rod devices sit in the same class. The Falcon 24-C Series is a 36 inch Grade 1 narrow stile exit only device for 1-3/4 inch doors, and the Falcon 1690EO is a 3 foot narrow stile exit only device at the same grade. The Corbin Russwin ED7800 is the closest crossbar-style narrow stile equivalent, and it accepts operator trim if you need outside access. For a push pad rather than a crossbar, the DORMA 9600BB is a 36 inch narrow stile Grade 1 device, non fire rated.
6) What is the closest crossbar concealed vertical rod exit device to the Von Duprin 5547L-3 for a narrow stile opening?
The Corbin Russwin ED7800 is the nearest match in style and stile type. It is a Grade 1 narrow stile crossbar concealed vertical rod exit device with a 1-3/4 inch door thickness range, the same crossbar push style and narrow stile fit as the 5547L-3, which is also Grade 1 with a 1-3/4 inch door thickness and cross bar actuation. The difference is function: the 5547L-3 is exit only with no outside trim, while the ED7800 is exit only but accepts operator trim, so it can be ordered later with an outside lever or pull.
7) The opening is a fire rated door - can I use the 5547L-3 or should I look at something else?
If the drawing calls out a labeled fire rated concealed vertical rod device, the Adams Rite 3600 Series and 3900 Series are both fire rated Grade 1 concealed vertical rod exit devices, though both are wide stile. The Sargent 12-MD8613 is a fire rated Grade 1 classroom function concealed vertical rod device, also wide stile. Note that fire rated devices are supplied without dogging, so you would lose the hex key dogging hold-open the 5547L-3 provides.
8) My door is wide stile, not narrow - what concealed vertical rod device works there instead?
The 5547L-3 is built for narrow stile doors with stiles as slim as 1-3/4 inches. For a wide stile opening, the Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors, and the DORMA 9100 Series is a Grade 1 heavy duty wide stile concealed vertical rod device with a 1-3/4 to 2-1/4 inch door thickness range. Both use a pushpad or wide stile chassis rather than the narrow stile crossbar case of the 5547L-3.
9) Can the 5547L-3 be held in the unlocked position during business hours?
Yes. It ships with hex key dogging, so a maintenance person depresses the crossbar and sets it with a hex wrench to hold the latches retracted for push-pull operation during the day, then releases it at close. Keep in mind that hex key dogging is a mechanical hold and is not used on fire rated openings.
10) Is the Von Duprin 5547L-3 Grade 1 for a high traffic commercial opening?
It carries ANSI/BHMA Grade 1 and is rated commercial, which is the level specified for school corridors, hospitals, office towers and other openings taking heavy daily cycles. The 55 Series crossbar style is the classic Von Duprin look, so it also suits older or historically styled buildings where a modern push pad would read wrong.
11) Does the 5547L-3 come with mounting screws, or do I need to buy a fastener pack?
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 any outside trim, since this is a less trim exit only device, and any electrified or monitoring option you want has to be specified separately.
12) Can I add access control or an alarm interface to the 5547L-3 later?
The 55 Series supports an E8875 electrified option for tying the device into access control or a fire alarm system, an RX request-to-exit monitoring switch for signalling that the bar has been pushed, and a KN knurled crossbar option used as a tactile warning on hazardous-area doors. These are ordering options rather than field add-ons, so specify them with the device.
13) Is there a push pad narrow stile concealed vertical rod device in 36 inch instead of a crossbar?
Yes. The 5547L-3 is a 36 inch crossbar device. If the specification calls for a push pad on a narrow stile door at the same width, the DORMA 9600BB Series is a 36 inch non-fire rated Grade 1 narrow stile pushpad concealed vertical rod device with a 1-3/4 to 2-1/4 inch door thickness range. The crossbar look of the 55 Series is often specified for retro-inspired and historical architecture, while the 9600BB presents a flat touchpad.
14) I need the inactive leaf of a pair to match the 5547L-3 - is the Falcon 1491DT a substitute?
No, they are not interchangeable. The Falcon 1491DT is a dummy trim narrow stile concealed vertical rod device with a 9970 pull in a 42 inch length, so it has no latching or egress function. The Von Duprin 5547L-3 is a working exit only device with a 1/2 inch latch throw. Use the 1491DT only where a non-functioning matching appearance is wanted, not where the leaf must latch or provide egress.
15) Are there non-handed concealed vertical rod exit devices comparable to the 5547L-3?
Yes. The Von Duprin 5547L-3 is field reversible, so one device covers either hand. 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 in exit only function, though wide stile. The BEST Precision 2701 Series is a wide stile reversible version built for wood doors.
16) What finish does the Von Duprin 5547L-3 come in?
Satin chrome, finish code 626. If you are standardizing a building, 626 is the common commercial satin finish and will sit consistently alongside most Grade 1 lever and closer hardware in the same code.
