Sargent AD8574E 32D – Frequently Asked Questions

1) Will the Sargent AD8574 exit device fit an aluminum storefront door with a 1-3/4 inch stile?

Yes. The AD8574 is a narrow stile rim device built for 1-3/4 inch minimum stiles, which is what aluminum frame full glass storefront doors give you. It also needs a 1-3/4 inch thick door. If your stile is narrower than 1-3/4 inches, no rim device in this family will land on it.

2) What does fail secure mean on the Sargent AD8574, and what happens in a power outage?

Fail secure means the outside trim stays locked when power is lost. Power is applied to release the outside lever; drop the power and the lever goes rigid again. The push pad always retracts the latch from the inside regardless of power, so egress is never electrically controlled. If you need the opening to unlock on a power drop instead, fail secure is the wrong function.

3) Which rail size do I order for a 36 inch door on the Sargent AD8574?

Rails come in 32, 36, 42, and 48 inch sizes, and they map straight to standard door widths, so a 36 inch door takes the 36 inch rail with no cutting. The device covers door widths from 24 to 48 inches overall. Pick the rail matching your leaf width rather than sizing up and trimming.

4) Do I have to specify handing on the Sargent AD8574 narrow stile device?

Handing is required. The AD8574 is ordered either RHR (right hand reverse) or LHR (left hand reverse), and it is not field reversible on the order form, so get the hand right before you buy. Stand outside the opening: if the door swings toward you and the hinges are on your right, it is RHR. If you want a non-handed mortise exit device instead, the Von Duprin 8875 and 9875 are listed as non-handed, and the Von Duprin 5575 narrow stile crossbar device is field reversible.

5) Can I dog down the Sargent AD8574 to leave the door on push-pull during business hours?

Only on the standard version. The fire rated build is less dogging, which is how every listed fire exit device works, so it cannot be held retracted mechanically. If you need the latch held back on a fire rated opening, order the 56 remote dogging / latch retraction or 58 electric dogging option and control it electrically instead.

6) Does the Sargent AD8574 come with outside lever trim or do I order that separately?

Trim is a separate selection. You can take the device on its own (exit only) or add ET trim in A, B, E, F, J, L, P, or W lever designs. Since this is the fail secure electrified function, the outside lever is what the access control system controls, so most jobs need trim specified. Choosing the lever design is where you match the other openings in the building.

7) Should I use a narrow stile rim exit device or a wide stile device on my doors?

It comes down to the stile you have. The AD8574 is the narrow stile answer, sized for 1-3/4 inch minimum stiles on aluminum full glass doors. On a hollow metal or wood door with a wide stile, the mounting is different and you want a wide stile device such as the Corbin Russwin ED5600AL, the Falcon 25-M-EO, or the Von Duprin 9875. Measure the flat face of the stile before you choose; putting a wide stile device on a storefront leaf leaves you nothing to fasten to.

8) Is a Von Duprin 8875 or 9875 a drop-in replacement for a Sargent AD8574 on an aluminum storefront door?

No. Both are wide stile devices: the 8875-3FT is a wide stile crossbar mortise exit device in a 36 inch size and the 9875-3FT is a smooth case wide stile mortise device, and neither is rated for wood doors. The AD8574 is a narrow stile device sized for 1-3/4 inch minimum stiles on aluminum frame full glass doors, so a wide stile chassis has no room on that stile face and the mortise prep will not correspond. The narrow stile peers to look at for that opening are the Von Duprin 5575-3ft and the Adams Rite 8400 Series. Add that the AD8574 is electrified fail secure, which the crossbar mechanical devices do not provide.

9) The opening is a wide stile hollow metal door, not aluminum glass - what mortise exit device fits instead of the Sargent AD8574?

The AD8574 is built for 1-3/4 inch minimum narrow stiles including aluminum frame full glass doors, so a wide stile hollow metal leaf calls for a wide stile device. Several fit that opening: the Adams Rite 8300 Series is a Grade 1 life-safety wide stile mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 wide stile mortise device for 1-3/4 inch doors that accepts passage or classroom lever trim. The Von Duprin 9875-3FT is a Grade 1 smooth case wide stile mortise device that is non-handed, though it is not rated for wood doors. Match the device family to the door construction first, then pick trim.

10) What is the closest narrow stile mortise exit device to the Sargent AD8574 from another brand?

The Adams Rite 8400 Series is the nearest narrow stile peer. It is a life-safety narrow stile mortise exit device built for aluminum doors, carrying a Grade 1 rating, which lines up with the AD8574's narrow stile construction and Grade 1 certification. The difference to weigh is function: the AD8574 is a fail secure electrified device, so it is specified when the opening needs powered control and the electric options such as latchbolt monitoring or electric dogging. The 8400 Series is a mechanical life-safety device with no fire rating, so an aluminum storefront opening that only needs free egress and a keyed outside trim is fully served by it without a power supply or wiring run.

11) Which narrow stile mortise exit device can be handed in the field instead of ordering handing up front?

The Von Duprin 5575-3ft is field reversible. It is a narrow stile crossbar mortise lock exit device in a 3 ft length with a Grade 1 rating and a 1-3/4 inch door thickness, and it is not fire rated. That matters for stock: one unit covers either hand of an aluminum opening. The Sargent AD8574 is ordered to hand, RHR or LHR, because the electrified fail secure function and the ET trim wiring are built to the specified hand. A locksmith carrying a truck stock of a single narrow stile device leans toward the field reversible 5575; a job where the hands are known and powered control is required specifies the AD8574 per opening.

12) Which mortise exit device should be specified for a fire rated opening instead of a standard one?

The Adams Rite 3300 Series is a fire rated Grade 1 mortise exit device for wood and hollow metal doors, so it suits a wide stile fire door assembly. On the narrow stile side, the Sargent AD8574 is ordered with the Fire Rated (Less Dogging) rating option, which removes dogging as fire rated devices require the latch to project at all times. Note which peers are not candidates for a fire opening: the Adams Rite 8300 and 8400 Series, the Von Duprin 5575, 8875 and 9875, and the 9475/9575 Impact Series are all listed as not fire rated.

13) Which mortise exit device accepts classroom lever trim without going electrified?

The Corbin Russwin ED5600AL accepts passage or classroom lever trim, sold exit only or with the trim added separately, and it is a Grade 1 wide stile device for 1-3/4 inch doors with a 3 hour fire rating. That covers a classroom function opening mechanically, keyed from outside, with no power supply. The Sargent AD8574 reaches outside control through ET lever trim in A, B, E, F, J, L, P and W lever styles combined with fail secure electrified operation, so entry is released by the access control system rather than by key alone. Choose the ED5600AL where a mechanical classroom function is acceptable and the door is wide stile; choose the AD8574 where the opening is narrow stile and must be controlled electrically.

14) Is the Sargent AD8574 available fire rated?

Yes, the AD8574 can be ordered fire rated, and that build comes less dogging. The device is ANSI/BHMA A156.3 Grade 1 either way. A windstorm rated build is also available by ordering WS.

15) What voltage does the Sargent AD8574 electrified exit device run on?

Two choices, 12V or 24V, and you specify one when ordering. Match it to the power supply and access control panel already on the job. Nothing in the device converts between the two, so a 24V head end will not drive a 12V unit.

16) How do I get door position or latch status back to my access control panel on a Sargent AD8574?

Order one of the switch options. 53 gives a latchbolt monitor switch that reports whether the latch is actually thrown, 55 is a signal switch in the rail that reports push pad actuation, and 54 puts an internal micro switch in the ET control trim. 59 Electroguard and AL alarmed are the other electric options, with AL requiring a 36 inch minimum door width. Integrators usually pair 53 with a separate door contact so the panel can tell secure from merely closed.

17) Can the Sargent AD8574 secure a pair of doors?

Yes, with a mullion. It's a single point rim latching device, so it latches into a strike at the jamb. On a pair with no center post you add a removable mullion for the rim device to latch into. The AD8574 works on single and double door configurations, wood or metal doors, with mullion options.

18) Is the Sargent AD8574 rated for high traffic commercial use?

It carries ANSI/BHMA A156.3 Grade 1, the top commercial durability grade for exit devices, and is catalogued for commercial rather than residential service. That is the grade specifiers write for schools, healthcare, and government entrances where the door cycles all day.

19) Can I order the AL alarmed option on a 32 inch door?

No. The AL alarmed option needs a 36 inch minimum door width, so a 32 inch leaf rules it out. On a 32 inch door you can still take the other electric options such as the 53 latchbolt monitor switch or the 55 signal switch in the rail to get status back to a panel, and let the alarm live at the head end instead.

20) What is a simpler mechanical alternative when the door only needs exit and no outside trim?

Exit-only devices skip the outside trim and the wiring entirely. The BEST Precision 2301 Series is a mortise exit device configured exit only with heavy wrought construction, the Falcon 25-M-EO is an exit only Grade 1 mortise device in a 36 inch wide stile 3 ft size for 1-3/4 inch doors, and the Detex 30 Series Advantex is a Grade 1 device-only exit device for wide stile doors that is not rated for wood. The Sargent AD8574 is specified when the opening needs more than egress: fail secure electrified operation plus options like the latchbolt monitor switch, remote latch retraction, or electric dogging, and ET lever trim for controlled entry from outside.

21) What is the alternative when the wide stile opening takes heavy abuse and a recessed push pad is preferred over a crossbar?

The Von Duprin 9475/9575 Impact Series is a mortise lock exit device with a recessed push pad built for wide stile doors, Grade 1 and not fire rated. The recessed pad keeps the actuator inside the device case, which suits openings that see carts and heavy traffic. The Von Duprin 8875-3FT and 5575-3ft are crossbar devices by contrast, and the Sargent AD8574 is a narrow stile rim latching device with a rail sized to the door, offered in 32, 36, 42 and 48 inch sizes. The Impact Series applies only to wide stile leaves, so it is not a route for an aluminum storefront stile.

22) What finishes does the Sargent AD8574 come in for matching existing hardware in a building?

Twelve finishes, so matching a fleet of openings is usually possible: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 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, 32D satin stainless, plus BSP black and WSP white suede powder coat. 32D is the usual commercial default and BSP is the common match for dark anodized storefront.
