Sargent AD8504E 32D – Frequently Asked Questions

1) Will the Sargent AD8504 work on an aluminum storefront door with a narrow stile?
That's exactly what the AD8504 is built for. It's a narrow stile rim device rated for a 1-3/4 inch minimum stile, so it fits aluminum frame full glass doors where a wide stile device would overhang the glass. Door thickness is 1-3/4 inches standard, wood or metal, with thicker doors handled as a special order.
2) What does night latch function mean on the Sargent AD8504 exit device?
Night latch means free egress from the inside at all times, and outside access only by key. There's no lever or knob operation from the outside on a night latch, so the AD8504 with no trim is the setup for a service door or a back door you want locked from the street but always exitable. If you need lever entry from outside, that's a different function.
3) Do I have to specify handing when ordering the Sargent AD8504?
Yes, handing is required, and it's reverse bevel: RHR (right hand reverse) or LHR (left hand reverse). Stand outside the door, in the direction the door swings toward you. Exit devices are on doors that swing out, which is why both options are reverse. Get it wrong and the device won't latch on your opening.
4) Can the Sargent AD8504 secure a pair of doors?
It can, with a mullion. The AD8504 is a single point rim device, so it latches into a strike at the frame, not at the head and threshold. On a pair with no center mullion there's nothing for it to catch, so you'd add a removable mullion between the leaves and run a device on each. It also handles single doors directly.
5) What's the difference between the Sargent AD8504 and a wide stile exit device like the Von Duprin 9875?
Stile width decides it. The AD8504 is narrow stile, sized for 1-3/4 inch minimum stile aluminum and glass doors. The Von Duprin 9875 is a wide stile Grade 1 mortise device for 1-3/4 inch doors and is not rated for wood doors. On a hollow metal or wood door with a wide stile you have room for either; on a storefront door you don't, and the narrow stile device is the only one that mounts.
6) What narrow stile mortise exit device works as an alternative to the Sargent AD8504 on an aluminum glass door?
The Adams Rite 8400 Series is a narrow stile mortise exit device built for aluminum doors, and the Von Duprin 5575-3ft is a narrow stile mortise lock exit device rated Grade 1 for 1-3/4 inch doors. The AD8504 is also narrow stile and Grade 1, so all three suit the same narrow aluminum stile opening. The difference is in actuation and handing: the AD8504 is ordered right hand reverse or left hand reverse, while the 5575-3ft is field reversible and uses a crossbar rather than a push rail.
7) The opening needs a fire rated mortise exit device - can a Sargent AD8504 be used?
For a fire rated mortise exit device, the Adams Rite 3300 Series is fire rated and Grade 1 for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 three hour fire rated mortise exit device for 1-3/4 inch doors. Both are wide stile devices, so the door needs a wide stile to take them. The AD8504 is a narrow stile Grade 1 device with a night latch function and is specified where the stile is 1-3/4 inch minimum, including aluminum frame full glass doors.
8) Which mortise exit devices look like a substitute for the Sargent AD8504 but will not fit a narrow aluminum stile?
The Von Duprin 8875-3FT, Von Duprin 9875-3FT, Von Duprin 9475/9575 Impact Series, Detex 30 Series Advantex, and Falcon 25-M-EO are all Grade 1 mortise exit devices, but every one of them is a wide stile device. They share the mortise lock format with the Sargent AD8504 and will not land on a 1-3/4 inch minimum stile. The AD8504 is the narrow stile device in that group and is the one engineered for aluminum frame full glass doors.
9) The doors are wood - which mortise exit devices are ruled out next to the Sargent AD8504?
Among Grade 1 mortise exit devices, the Detex 30 Series, Von Duprin 8875-3FT and Von Duprin 9875-3FT are all listed as not wood door compatible. The Adams Rite 3300 Series and 8300 Series are mortise exit devices for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 device for 1-3/4 inch doors. The Sargent AD8504 carries standard compatibility with 1-3/4 inch thick wood or metal doors.
10) Can I add a lever to the outside of the Sargent AD8504?
Eight ET trim levers are available on the AD8504: A, B, E, F, J, L, P and W lever styles, or you can order it exit device only with no outside trim. Pick the lever style to match the other openings in the building; the letter is the lever shape, not a function change.
11) Is the Sargent AD8504 rated for a high traffic commercial entrance?
ANSI/BHMA A156.3 Grade 1, the heavy duty commercial rating, and the device is a commercial product rather than a residential one. That's the grade specifiers write for school, healthcare, and office entrances that see constant use.
12) I need a windstorm rated exit device for a coastal building. Does Sargent offer one on the AD8500?
Yes, the AD8504 can be ordered with the WS windstorm rating suffix. It's an order option, not standard, so it has to be specified at time of order.
13) I want a lever that unlocks with a key for classroom use, not night latch. What should I look at?
Night latch on the AD8504 gives key-only outside access, with no lever entry. If you want passage or classroom lever operation from the outside, the Corbin Russwin ED5600AL accepts passage or classroom lever trim and is a Grade 1 device for 1-3/4 inch doors, though it's wide stile so it needs a wider door than a storefront leaf.
14) Can I put the Sargent AD8504 on a wood door?
Yes, 1-3/4 inch thick wood or metal doors are the standard application, with thicker doors available as a special order. That's worth noting because some Grade 1 mortise exit devices are metal door only, including the Von Duprin 8875 and 9875 and the Detex 30 Series.
15) Does the Sargent AD8504 need a separate lock in the door, or is the device the whole thing?
The device is the whole latching mechanism. The AD8504 is a single point rim device with a rim bolt, so it latches into a strike mounted on the frame rather than into a mortise pocket cut in the door edge. That keeps the door prep lighter on an aluminum stile, and the rim bolt design is what gives it quiet operation.
16) If no lever trim is needed on the outside, what is a simpler option than a Sargent AD8504?
For an exit only opening with no outside trim, the Falcon 25-M-EO is a mortise exit device with an exit only function, the BEST Precision 2301 Series is exit only with heavy wrought construction, and the Detex 30 Series is a device only exit only unit. All three are wide stile devices. The Sargent AD8504 can be ordered as exit device only with no trim as well, and its night latch function is what allows key retraction of the latch from outside when that is wanted later.
17) What is the difference between the Sargent AD8504 and the Adams Rite 8400 Series for a non fire rated aluminum door?
Both are narrow stile mortise exit devices. The Adams Rite 8400 Series is a life safety narrow stile mortise device for aluminum doors and is not fire rated. The Sargent AD8504 is Grade 1 with a night latch function and is ordered in 32, 36, 42 and 48 inch sizes, in finishes from bright brass and satin stainless steel through black and white suede powder coat, with ET lever trim in A, B, E, F, J, L, P and W lever styles or as device only.
18) Is the Sargent AD8504 push rail or crossbar, and what is the crossbar equivalent?
If the building standard is a crossbar device, the Von Duprin 5575-3ft is a narrow stile crossbar mortise lock exit device, Grade 1 and field reversible, and the Von Duprin 8875-3FT is the wide stile crossbar version at 36 inches, non handed. The Sargent AD8504 is a single point rim latching device with a rim bolt design for quiet operation, ordered in a specific hand, right hand reverse or left hand reverse.
19) For a high abuse entrance, what mortise exit device compares to the Sargent AD8504?
The Von Duprin 9475/9575 Impact Series is a Grade 1 mortise lock exit device with a recessed push pad for wide stile doors, and the BEST Precision 2301 Series is a mortise exit device with heavy wrought construction. Both are for openings where the device takes abuse. The Sargent AD8504 is Grade 1 to ANSI/BHMA A156.3 for heavy duty commercial use on narrow stiles, and can be ordered with a windstorm rating using the WS option.
20) What finishes does the Sargent AD8504 come in to match existing hardware?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black and WSP white suede powder coat. For a storefront matching aluminum doors, 32D satin stainless or the black powder coat are the usual picks.
