Sargent AD8540E 32D – Frequently Asked Questions

1) What does the dummy function on the Sargent AD8540 actually do?
Dummy means no latching. The AD8540 is a dummy function device with freewheeling trim, so the push rail and lever are there for appearance and matching, not for securing or releasing a latch. On a pair of doors this is what you put on the inactive leaf so both sides look identical to the active exit device. If you need the door to latch and release, you need an active function from the AD8500 Series instead.
2) Will a Sargent AD8540 fit an aluminum storefront door?
That is what it is built for. The AD8540 is a narrow stile device rated for a 1-3/4 inch minimum stile, which covers aluminum frame full glass storefront doors. It is set up for 1-3/4 inch thick doors, wood or metal, with provisions for thicker doors. Measure your lock stile before ordering: anything under 1-3/4 inches and no narrow stile rim device will land on it.
3) What door widths does the Sargent AD8540 cover, and do I have to cut the rail?
Door widths from 24 to 48 inches are covered. Rail lengths come in 32, 36, 42, and 48 inch sizes, and those four standard door widths install with no cutting. If your opening falls between sizes, you take the next rail up and cut it down.
4) Do I have to specify handing on the Sargent AD8540?
Yes, handing is required. You pick RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always a reverse bevel, so stand outside the opening: if the door swings away from you and the hinges are on your right, it is RHR. Get this wrong and the device will not mount correctly.
5) What is the difference between a narrow stile device like the Sargent AD8540 and a wide stile exit device?
Stile width decides it. The AD8540 is narrow stile, built for a 1-3/4 inch minimum stile such as an aluminum glass door. Wide stile devices, like the Von Duprin 9875 or the Corbin Russwin ED5600AL, are for hollow metal and wood doors with a full-width lock stile and physically will not fit a storefront rail. If you are working a glass front, stay narrow stile.
6) What is the closest narrow stile alternative to the Sargent AD8540 for an aluminum glass door?
Two narrow stile Grade 1 mortise exit devices sit alongside the Sargent AD8540: the Adams Rite 8400 Series, a life-safety narrow stile mortise exit device built for aluminum doors and listed as non fire rated, and the Von Duprin 5575-3ft, a narrow stile crossbar mortise lock device in a 3 ft length, Grade 1, field reversible, for 1-3/4 inch doors. The AD8540 differs in operation from both in that it is a dummy function device with freewheeling trim, so the trim does not retract a latch; the Adams Rite 8400 and Von Duprin 5575 are latching devices. Choose on whether the opening needs a working latch or a pull-only dummy.
7) I need a fire rated exit device. Is the Sargent AD8540 the right choice?
The Sargent AD8540 is a dummy function device with freewheeling trim, which is a non-latching pull configuration and not what a fire rated opening calls for. For fire labeled openings, the Adams Rite 3300 Series is a fire rated Grade 1 mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device for 1-3/4 inch doors that can be ordered exit only or with passage or classroom lever trim. Both are wide stile devices, so confirm your stile width before specifying either.
8) My opening is a wide stile hollow metal door, not aluminum. What should I use instead of the Sargent AD8540?
The Sargent AD8540 is built for narrow stile openings with a 1-3/4 inch minimum stile, including aluminum frame full glass doors, so it is the wrong device for a wide stile hollow metal leaf. Wide stile Grade 1 mortise exit devices to look at instead include the Von Duprin 9875-3FT smooth case device in 3 ft, non-handed, for 1-3/4 inch doors; the Von Duprin 8875-3FT crossbar version at 36 inches; the Falcon 25-M-EO in a 36 inch wide stile exit only configuration; and the Adams Rite 8300 Series for wood and hollow metal doors. Note that both Von Duprin 88 and 98 series devices listed here are not wood door compatible.
9) Is the Sargent AD8540 Grade 1?
ANSI/BHMA A156.3 Grade 1, the top commercial rating for exit devices. An optional WS windstorm designation is also available if the opening is in a coastal or high wind zone.
10) What lever trim options come with the Sargent AD8540?
Eight ET lever styles are offered: A, B, E, F, J, L, P and W. You can also order the device on its own with no trim if you are reusing existing pulls or matching trim from another source. Since this is a dummy function, the lever freewheels, so pick the style that matches the active leaf rather than worrying about function.
11) Can I get an alarmed or electric dogging version of the Sargent AD8540?
Electric options include 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 catch worth knowing up front: the AL alarmed option requires a 36 inch minimum door width, so it is not available on the 32 inch size.
12) Can the Sargent AD8540 be used on a pair of doors?
Yes. The AD8500 Series works on single and double doors, including mullion configurations. On a pair, the AD8540 dummy typically goes on the inactive leaf so the appearance matches the active exit device, while the latching device and the mullion handle the security.
13) What is the difference between the Sargent AD8540 and an exit only device like the BEST Precision 2301 or Falcon 25-M-EO?
The Sargent AD8540 carries a dummy function and is offered with ET trim in A, B, E, F, J, L, P and W lever styles, or with no trim at all. The BEST Precision 2301 Series is a mortise exit device configured exit only with heavy wrought construction, and the Falcon 25-M-EO is likewise an exit only mortise device in a 36 inch wide stile length. Exit only means no outside trim is provided or operable; the AD8540 dummy arrangement gives an outside lever that is present for appearance and pull but freewheels rather than retracting a latch. Pick the AD8540 when the outside face needs a matching lever, exit only when the outside face should be blank.
14) Is the Von Duprin 5575 a drop-in substitute for the Sargent AD8540?
Both are Grade 1 narrow stile mortise exit devices, but they are not interchangeable without checking the opening. The Von Duprin 5575-3ft is a crossbar style device supplied in a 3 ft length, non fire rated, field reversible for 1-3/4 inch doors. The Sargent AD8540 is a push rail device ordered by hand, RHR or LHR, in 32, 36, 42 and 48 inch rail sizes, and it is a dummy function unit rather than a latching one. Door prep, rail length and the handing call all differ, so treat the 5575 as an alternative device rather than a retrofit into existing AD8540 prep.
15) What finishes does the Sargent AD8540 come in for matching existing hardware?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE, 10BL, 20D dark statuary bronze, 32 bright stainless, 32D satin stainless, plus BSP black suede and WSP white suede powder coat. For storefront work 32D and the two powder coats are the usual match to dark and clear anodized aluminum.
16) For a high abuse opening, how does the Sargent AD8540 compare to the Von Duprin 9475/9575 Impact Series?
The Von Duprin 9475/9575 Impact Series is a Grade 1 mortise lock exit device with a recessed push pad for wide stile doors, non fire rated, and the recessed pad is aimed at openings that take cart and traffic abuse. The Sargent AD8540 is a Grade 1 narrow stile device for 1-3/4 inch minimum stile openings such as aluminum frame full glass doors, in a dummy function. The deciding factor is the door itself: the Impact Series will not fit a narrow aluminum stile, and the AD8540 is not a wide stile device.
17) Does the Detex 30 Series Advantex do the same job as the Sargent AD8540?
Not for the same opening. The Detex 30 Series Advantex is a Grade 1 wide stile mortise lock exit device configured device only, exit only, and it is not wood door compatible. The Sargent AD8540 is a narrow stile device in a dummy function that accepts ET lever trim in several lever styles and is ordered RHR or LHR. If the requirement is a narrow aluminum stile with an outside lever, the Detex 30 does not cover it.
