Sargent AD8406E 32D – Frequently Asked Questions

1) Will the Sargent AD8406 exit device fit a narrow stile aluminum storefront door?
The AD8406 is built for narrow stile openings, with a 1-3/4 inch minimum stile width and a hollow stile interior of at least 1-3/8 inches square. That hollow interior requirement is the one that catches people out: the concealed vertical rods run inside the stile, so if the stile is solid or the cavity is smaller than 1-3/8 inches square, the rods have nowhere to go and the device will not install no matter how wide the face of the stile measures. Check the cavity, not just the stile face.
2) Which rail length do I order for my door width on the Sargent AD8400 exit device?
Rails are factory cut to the opening, so you pick by door width: E Rail covers 24 to 32 inches, F Rail 33 to 36 inches, J Rail 37 to 42 inches, and G Rail 43 to 48 inches. Orderable device sizes are 32, 36, 42 and 48 inches. Measure the actual door leaf before you commit, because a factory-cut rail is not something you trim on site.
3) Do I have to specify handing on the Sargent AD8406?
Yes, handing is required and there is no field-reversible option. You choose RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always reverse bevel because they swing out in the direction of egress, so stand outside the door: if the hinges are on your right it is RHR, on your left it is LHR. Order the wrong hand and the device will not work on the opening.
4) What does storeroom function mean on a Sargent AD8406 exit device?
Storeroom function means the outside lever is always locked. You get out from the inside any time by pushing the touchpad, but from the outside the lever is rigid and a key in the trim cylinder retracts the latch for entry only. The lever does not stay unlocked after the key is turned. That is the standard choice for mechanical rooms, electrical closets, stockrooms and any tenant space you want secured around the clock. If you want a door that can be left unlocked for the day, storeroom is the wrong function.
5) What is the alternative to the Sargent AD8406 if my doors are wide stile instead of narrow stile?
The AD8406 will not work on a wide stile door prep, and there are several Grade 1 wide stile mortise devices to go to instead. The Corbin Russwin ED5600AL is a 3 hour fire rated wide stile mortise device for 1-3/4 inch doors that takes passage or classroom lever trim. The Von Duprin 9875-3FT is a 36 inch smooth case wide stile mortise device, Grade 1 and non-handed. The Falcon 25-M-EO is a 36 inch wide stile exit only device for 1-3/4 inch doors. Adams Rite also offers the 3300 Series, a Grade 1 fire rated mortise device for wood and hollow metal doors.
6) What other narrow stile exit devices could I use instead of the Sargent AD8406?
Two other narrow stile devices are worth looking at, and neither is a straight swap. The Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device for aluminum doors, but it is not fire rated, so it cannot go on a fire opening the way the AD8406 can. The Von Duprin 5575-3ft is a Grade 1 narrow stile crossbar mortise device at 3 feet for 1-3/4 inch doors, field reversible, and also not fire rated. The crossbar on the Von Duprin is a different look and feel from a touchpad rail, which matters if you are matching existing openings.
7) Which mortise exit device replaces a Sargent AD8406 on a wood door?
The Sargent AD8406 is built for hollow metal narrow stile construction. For a wood door, the Adams Rite 3300 Series is a Grade 1 fire-rated mortise exit device for wood and hollow metal doors, and the Adams Rite 8300 Series is the Grade 1 wide stile equivalent for wood and hollow metal without a fire rating. The Von Duprin 8875, 9875, and Detex 30 Series are each listed as not wood door compatible, so they do not cover that opening.
8) What is the closest narrow stile mortise exit device to the Sargent AD8406 if fire rating is not required?
The Von Duprin 5575 is a narrow stile mortise lock exit device rated Grade 1, with a 1-3/4 inch door thickness and field reversible handing, but it carries no fire rating. The Sargent AD8406 is also Grade 1 and built for narrow stile openings, and it is UL Fire and Panic listed, so it is the one that belongs on a labeled fire door. The 5575 uses a crossbar actuator rather than a pushbar, which changes the look and the reach across the door face.
9) Is a Von Duprin 9875 or 8875 a substitute for a Sargent AD8406?
No. The Von Duprin 9875 and 8875 are both wide stile Grade 1 mortise exit devices for 1-3/4 inch doors, non-handed, with no fire rating and not compatible with wood doors. The Sargent AD8406 is a narrow stile device requiring a 1-3/4 inch minimum stile, it is UL Fire and Panic listed, and it is ordered handed as RHR or LHR. Swapping one for the other changes the stile the device mounts to and the fire listing on the opening.
10) Should I use a concealed vertical rod device or a rim device with a mullion on a pair of doors?
Concealed vertical rod is what you use when you cannot have a mullion in the opening, or when you do not want hardware showing on the door face. The AD8406 latches at the head and at the threshold through rods hidden inside the stile, so a pair of doors secures with no center post and nothing sticking out where carts and gurneys pass. The trade is prep and service: the door has to have a hollow stile of at least 1-3/8 inches square to take the rods, and rod adjustment is inside the door rather than on the surface. A rim device with a removable mullion is simpler to install and service, but you live with a post in the middle of the clear opening.
11) What lever trim options can I order with the Sargent AD8406?
Eight ET trim lever designs are available (A, B, E, F, J, L, P and W levers), or you can order the device exit only with no outside trim. With storeroom function the trim carries the key cylinder, so if you need key access from the outside you need trim; exit only means the door is push-to-exit with no outside operation at all. Pick the lever design to match the levers already hanging on your other openings.
12) How much space does the Sargent AD8406 push bar take up in the door opening?
Push bar projection is 3 inches at neutral and 2-1/8 inches when depressed, and the center case measures 8-3/8 by 2-5/8 inches. Those 3 inches come off your clear width when the door is open against a wall or another leaf, which matters in tight vestibules and on pairs where two devices face each other.
13) What height is the Sargent AD8400 exit device mounted at, and can it go lower for a school?
Standard centerline is 41 inches from finished floor. A 38 inch centerline is offered for elementary schools and accessibility, and that option is used together with the 100 Series Auxiliary Control. Specify the 38 inch mounting at order time rather than trying to drop the device later, since the door prep is cut for the height you buy.
14) Is the Sargent AD8406 Grade 1, and what does that mean for a high traffic door?
Grade 1 is the highest ANSI/BHMA durability classification, the tier specified for heavy commercial and institutional traffic, and the AD8406 is a Grade 1 commercial device. The top bolt is stainless steel, which is what you want on the bottom-of-the-opening and head hardware in an entrance that gets weather and cleaning chemicals. For a school corridor, a hospital entry, or a warehouse door cycling all day, that is the right specification.
15) Can I hold the Sargent AD8400 device dogged open during business hours?
Hex key dogging comes standard on the non-fire rated build, and cylinder dogging is available as an option using a #41 cylinder if you would rather dog with a key than a hex wrench. Electric dogging (58) and remote dogging / latch retraction (56) are the options when you want the door released from a front desk or on a time schedule. Dogging is not available on the fire rated version, since a fire door has to latch.
16) What is a simpler exit-only mortise device to use where the Sargent AD8406 storeroom lever trim is not needed?
The Falcon 25-M-EO is a Grade 1 exit only mortise device for 36 inch wide stile doors at 1-3/4 inch thickness, and the BEST Precision 2301 is an exit only mortise device with heavy wrought construction. The Detex 30 Series Advantex is Grade 1 and also supplied device only, exit only, for wide stile non-wood doors. All three are outside trim free by design. The Sargent AD8406 is a storeroom function device and can be ordered with ET lever trim in A, B, E, F, J, L, P, or W lever, or with no trim as exit device only.
17) What mortise exit device stands up to abuse better than a Sargent AD8406 in a high-traffic wide stile opening?
The Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad, which keeps the actuator behind the case face where carts and equipment strike it; it carries no fire rating. The BEST Precision 2301 is a wide stile mortise device with heavy wrought construction. The Sargent AD8406 uses an exposed pushbar with 3 inch projection neutral and 2-1/8 inch depressed, a stainless steel top bolt, and it is UL Fire and Panic listed, so it stays the choice where a labeled fire opening is involved.
18) Which alternative to the Sargent AD8406 accepts classroom lever trim instead of storeroom function?
The Corbin Russwin ED5600AL accepts passage or classroom lever trim and is supplied exit only, on a Grade 1 three hour fire rated wide stile mortise device for 1-3/4 inch doors. The Sargent AD8406 is a Grade 1 storeroom function device, so the outside lever stays locked and the key retracts the latch; if the specification calls for classroom keying behavior the ED5600AL is the device that matches, though it mounts on a wide stile rather than a narrow one.
19) What finishes does the Sargent AD8406 come in to match the rest of my building?
Twelve finishes are offered: bright brass (03), satin brass (04), bright bronze (09), satin bronze (10), dark oxidized satin bronze in oil rubbed (10B), plain (10BE) and clear coated (10BL), dark statuary bronze lacquered (20D), bright stainless (32), satin stainless (32D), plus black (BSP) and white (WSP) suede powder coat. 32D satin stainless is the usual commercial default and the one most likely to match existing openings; the powder coats are the ones to reach for when the door frames are painted rather than plated.
