Sargent AD8473E 10BE – Frequently Asked Questions

1) What is the minimum stile width for the Sargent AD8473 exit device?
The AD8473 needs a stile at least 1-3/4 inches wide with a 1-3/8 inch square hollow interior to take the concealed rods. If your aluminum or hollow metal door has less than that, the rods won't fit and you need a rim device or a wide stile device instead. The 1-3/8 inch square hollow is the part people miss: a stile can measure 1-3/4 inches on the face and still have too little clear interior once the glass pocket and webbing are accounted for. Measure the hollow, not just the face.
2) What does fail safe mean on the Sargent AD8473 and what happens in a power failure?
Fail safe on the AD8473 refers to the electrified trim: when power drops, the outside lever unlocks and allows entry. That is the setting you want where a power loss must not trap people on the wrong side of an opening, or where the access control system is expected to release on a fire alarm. If you need the opposite behavior, with the outside trim staying locked when power is lost, fail safe is the wrong function and you need the fail secure version of the AD8400 Series. Free egress from the inside is unaffected either way, because pushing the touchpad is always mechanical.
3) Is the Sargent AD8473 handed, and how do I determine which hand to order?
Handing matters here. The AD8473 is ordered as either RHR (right hand reverse) or LHR (left hand reverse), and it is a required selection, not a field-reversible device. Exit devices are always a reverse hand because the door swings out toward you when you stand outside. Stand on the outside of the door, the side you pull from: if the hinges are on your right it is right hand reverse, hinges on your left is left hand reverse. Get this wrong and the device will not work on the opening.
4) Can I get the Sargent AD8473 fire rated, and does that affect dogging?
The AD8473 is UL Fire and Panic listed and is ordered as either Standard or Fire Rated (Less Dogging). Fire rated openings cannot have mechanical dogging, because the latch has to be free to engage the moment the door closes, so the fire rated build comes without it. If you want to hold the latch retracted during business hours on a non-fire opening, order the Standard rating and look at the 56 remote dogging / latch retraction or 58 electric dogging options. Fire rated applications use the 650 Top Strike and 606 Bottom Strike.
5) What narrow stile exit device alternatives are there if the Sargent AD8473 doesn't suit my opening?
Two other narrow stile options: the Adams Rite 8400 Series is a Grade 1 life-safety narrow stile mortise exit device for aluminum doors, not fire rated, and the Von Duprin 5575 is a Grade 1 narrow stile crossbar mortise device, field reversible, for 1-3/4 inch doors, also not fire rated. The AD8473 is the one to keep if you need a fire rated opening or an electrified fail safe trim, since it is UL Fire and Panic listed. If you need a simple mechanical exit only device on a narrow stile aluminum door, the Adams Rite 8400 or the Von Duprin 5575 covers it with less to install and nothing to wire.
6) What should be used instead of the Sargent AD8473 when the door has a wide stile?
The AD8473 is engineered for narrow stile openings requiring a minimum 1-3/4 inch stile width, so a wide stile door does not need its dimensional constraints. Wide stile Grade 1 mortise exit devices include the Von Duprin 9875-3FT smooth case device, the Von Duprin 8875-3FT crossbar device, the Detex 30 Series Advantex, and the Falcon 25-M-EO. All four are Grade 1. If the wide stile opening is fire rated, the Corbin Russwin ED5600AL is a Grade 1 wide stile mortise exit device with a 3 hour fire rating, and the Adams Rite 3300 Series is a fire-rated wide stile mortise device for wood and hollow metal doors.
7) Is the Von Duprin 5575 a substitute for a Sargent AD8473?
The Von Duprin 5575-3ft is the closest narrow stile peer by stile type - it is a Grade 1 narrow stile mortise lock exit device rated for 1-3/4 inch door thickness and is field reversible. Two things separate it from the Sargent AD8473. The 5575 has no fire rating, where the AD8473 is UL Fire and Panic listed. And the 5575 is a crossbar device with a mortise lock, where the AD8473 is a concealed vertical rod device that latches top and bottom with a 650 top strike and 606 bottom strike. On a pair of doors or an opening prepped for vertical rods, the 5575 is not a drop-in.
8) Which mortise exit devices carry a fire rating for a labeled opening?
For a labeled opening, the Sargent AD8473 is UL Fire and Panic listed and is ordered in a Fire Rated (Less Dogging) configuration. Among the comparable mortise devices, the Adams Rite 3300 Series carries a fire rating, and the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device. The Adams Rite 8300 Series, Adams Rite 8400 Series, Von Duprin 5575-3ft, Von Duprin 8875-3FT, Von Duprin 9475/9575, and Von Duprin 9875-3FT are all specified as non fire rated and belong on non-labeled openings.
9) Should I use a concealed vertical rod exit device or a rim device on my aluminum entrance?
A concealed vertical rod device like the AD8473 latches at the head and the threshold with the rods hidden inside the stile, which is what you want on a pair of doors with no center mullion and where the clean look of a storefront entrance matters. A rim device latches into a strike on the frame or a removable mullion, is simpler to install and service, and is usually the cheaper path on a single door. Concealed rod costs you a prepped door: the stile has to be hollow and at least 1-3/4 inches with a 1-3/8 inch square interior, and adjusting rods later means opening the door up. Pick concealed rod for appearance and for pairs; pick rim where you have a single door or a mullion already.
10) What voltage does the Sargent AD8473 electrified exit device run on?
The AD8473 is ordered in either 12V or 24V, and voltage is a required selection at order time, so match it to the power supply and access control panel you already have on the job. There is no field switching between the two after the fact.
11) What lever trim can I get with the Sargent AD8473, and can I order the device without trim?
The AD8473 takes Sargent ET trim in eight lever designs: A, B, E, F, J, L, P and W. You can also order it as exit device only with no trim, which is the choice when the outside is a pull only or when the existing ET trim is being reused. If you are standardizing lever style across a building, pick the ET lever that matches the locksets on the rest of your openings.
12) Can I add alarm or door monitoring to the Sargent AD8473, and are there any restrictions?
Several electric options can be added to the AD8473: AL alarmed, 53 latchbolt monitor switch, 54 internal micro switch in the ET control, 55 signal switch in the rail, 56 remote dogging / latch retraction, 58 electric dogging, and 59 Electroguard. One restriction to plan around: the AL alarmed option requires a 36 inch minimum door width, so it is not available on the narrower 32 inch doors. If you need latch status back at the panel, the 53 latchbolt monitor is the switch that reports whether the door is actually secured, which is a different thing from a door position switch.
13) How much does the Sargent AD8473 project from the door face, and will it clear a tight vestibule?
The center case measures 8-3/8 x 2-5/8 inches, with 3 inch projection at neutral and 2-1/8 inches when the touchpad is depressed. In a vestibule or a narrow corridor where the door swings toward a wall or a second set of doors, that 3 inch neutral projection is the number to work with. Mounting centerline is 41 inches from finished floor as standard, or 38 inches on elementary school openings.
14) What is a Grade 1 rating on an exit device and does the Sargent AD8473 carry it?
The AD8473 is Grade 1, the heaviest of the three ANSI/BHMA grades and the one written into most commercial and institutional specs. Grade 1 is what you specify for high traffic openings: school entrances, hospital corridors, government buildings. If your drawing calls for Grade 1 panic hardware on a narrow stile door, this device meets that line.
15) What is the difference between a mortise exit device and a concealed vertical rod device on a pair of doors?
A mortise exit device latches sideways into the frame or a mullion from a lock case mortised into the door edge, so on a pair of doors it needs either a mullion or an active/inactive leaf arrangement. A concealed vertical rod device like the AD8473 throws a top bolt into the head and a bottom bolt at the threshold, which lets both leaves of a pair swing free with no center mullion at all, and the rods stay hidden inside the stile. If a mullion is acceptable on your opening, wide stile mortise options like the Von Duprin 9875 or the Detex 30 Series Advantex are Grade 1 devices for that approach. If you want an unobstructed opening, vertical rod is the answer.
16) Does the Sargent AD8473 come with mounting hardware, and what else do I need to order to finish the job?
Machine screw mounting fasteners are supplied with the AD8473, and the top bolt is stainless steel. The 650 top strike and 606 bottom strike go with it for panic and fire rated applications. Beyond that, decide up front on handing, standard versus fire rated, 12V or 24V, the exact door width for factory rail cutting, and whether you want ET lever trim or the device only. On the electrified side you supply the power and the wiring run to the door; a power transfer at the hinge side is what gets the conductors from frame to door.
17) If the opening does not need electrified trim, what is a simpler alternative to the Sargent AD8473?
The AD8473 is an electrified fail safe device, which means a power supply, wiring runs, and 12V or 24V selection. Where the opening only needs free egress and no access control, mechanical exit-only devices cover it: the Falcon 25-M-EO is a Grade 1 exit-only mortise device, the BEST Precision 2301 Series is an exit-only mortise device with heavy wrought construction, and the Detex 30 Series Advantex is a Grade 1 device-only, exit-only mortise device. None of these carry electrified trim, so they will not tie into an access control system the way the AD8473 does.
18) What is the difference between the Sargent AD8473 and the Von Duprin 9475/9575 Impact Series?
They latch differently and suit different doors. The Von Duprin 9475/9575 Impact Series is a Grade 1 mortise lock exit device with a recessed push pad, built for wide stile doors and specified as non fire rated. The Sargent AD8473 is a Grade 1 concealed vertical rod device for narrow stile openings with a minimum 1-3/4 inch stile width, UL Fire and Panic listed, with a fail safe electrified trim function. A recessed push pad on a wide stile door is a different opening entirely from a narrow stile aluminum or hollow metal entrance on vertical rods.
19) Can the Sargent AD8473 and the Adams Rite 8400 Series be mixed across a building for standardization?
Both are Grade 1 narrow stile mortise exit devices, so they suit the same class of stile. Standardizing on one across a facility is usually driven by two things. Trim and keying: the AD8473 takes ET trim in A, B, E, F, J, L, P and W lever styles, or exit device only. And openings: the AD8473 is UL Fire and Panic listed and covers doors 24 inch to 48 inch wide through four rail sizes, while the Adams Rite 8400 Series is a life-safety device without a fire rating. A facility with a mix of labeled and non-labeled narrow stile doors can run the AD8473 through both; a facility with no labeled narrow stile openings has more room to choose.
20) Does a 36 inch Falcon 25-M-EO drop into the same opening as a 36 inch Sargent AD8473?
No. The Falcon 25-M-EO is a 36 inch wide stile exit-only mortise device rated for 1-3/4 inch doors. The Sargent AD8473 in a 36 inch size is a narrow stile concealed vertical rod device that needs a minimum 1-3/4 inch stile with a 1-3/8 inch square hollow interior, latches into a 650 top strike and 606 bottom strike, and carries fail safe electrified trim. Matching device width does not mean matching door prep: the strike locations, stile requirement, and wiring are all different.
21) What finishes does the Sargent AD8473 come in for matching existing door hardware?
Twelve finishes are available on the AD8473: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 20D dark statuary bronze lacquered, 32 bright stainless steel, 32D satin stainless steel, BSP black suede powder coat, and WSP white suede powder coat. For matching a fleet of commercial openings, 32D satin stainless and the dark bronzes are the usual standards. BSP and WSP powder coats are the ones to look at when the entrance is painted storefront rather than anodized aluminum.
22) Are there illuminated or photoluminescent touchpad options on the Sargent AD8400 Series exit devices?
Yes, two of them. PL SARGuide is the photoluminescent touchpad, which charges off ambient light and glows during a power loss with nothing wired to it. TL SARGuide is the illuminated touchpad, which is powered. There is also a BT beacon option. On egress paths where you want the exit visible in smoke or a blackout, the photoluminescent version is the one that keeps working with no power at all.
