Sargent AD8640E 10BE – Frequently Asked Questions

1) What door widths does the Sargent AD8640 cover and do I have to cut the rail?
Doors from 24 to 48 inches wide, using four rail sizes: E rail for 24 to 32 inches, F rail for 33 to 36 inches, J rail for 37 to 42 inches, and G rail for 43 to 48 inches. Rails are factory cut when you specify the door width, so there is no field cutting. Orderable sizes are 32, 36, 42, and 48 inches. Maximum door height is 120 inches.
2) The Sargent AD8640 is dummy function - what mortise exit device should I use on the active leaf that actually latches?
The AD8640 is a dummy function device, so it provides the push rail and lever appearance without latching hardware operation. For an opening that needs a latching mortise exit device, the Corbin Russwin ED5600AL is a Grade 1 mortise exit device that can be ordered exit only or for use with classroom or passage lever trim, and the Falcon 25-M-EO is a Grade 1 mortise exit device in exit only function. Both are wide stile devices for 1-3/4 inch doors, which matches the 1-3/4 inch minimum thickness the AD8640 is built around.
3) The Sargent AD8640 needs 4-1/2 inch stile - what mortise exit device fits a narrow stile aluminum door?
The AD8640 requires a 4-1/2 inch minimum stile width, which rules out most aluminum storefront framing. For narrow stile openings, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device built for aluminum doors, and the Von Duprin 5575 is a Grade 1 narrow stile crossbar mortise device for 1-3/4 inch doors that is field reversible.
4) I need a fire rated mortise exit device instead of the Sargent AD8640 - what are my options?
The AD8640 carries hex key dogging as standard on non-fire rated devices, with cylinder dogging optional. If the opening requires a labeled fire exit device, the Adams Rite 3300 Series is a fire rated mortise exit device for wood and hollow metal doors, Grade 1, wide stile. The Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device for 1-3/4 inch doors. Note that fire rated devices do not permit mechanical dogging.
5) How much does the Sargent AD8640 stick out from the door face?
Projection is 3 inches at neutral and 2-1/8 inches when the pad is depressed, with a center case measuring 8-3/8 x 2-5/8 inches. Those are the numbers to check against a door swinging into a corridor or against adjacent hardware on a pair.
6) Can I mount a Sargent AD8640 lower than standard for an elementary school?
Yes. Standard centerline is 41 inches from finished floor, with a 38 inch option intended for elementary schools and accessibility applications. Specify the 38 inch height at order; it is a mounting height choice, not a field adjustment.
7) Does the Sargent AD8640 have dogging?
Hex key dogging is standard on non-fire rated devices, and cylinder dogging is available as an option with a #41 cylinder supplied. On fire rated openings mechanical dogging is not permitted, so specify 56 remote latch retraction or 58 electric dogging if you need the pad held down on a rated door.
8) What lever trim options come with the Sargent AD8640?
Freewheeling ET trim in eight lever designs: A, B, E, F, J, L, P and W. You can also order the device on its own with no trim. Because this is dummy function, the lever freewheels and does not retract anything.
9) Is the Sargent AD8640 Grade 1, and what strikes are included?
Grade 1, commercial duty. It ships with the 650 top strike and 606 bottom strike, covering both panic and fire rated applications, and uses a stainless steel top bolt.
10) Why choose a concealed vertical rod device over a surface mounted one?
Concealed vertical rod runs the rods inside the door, so nothing is exposed to abuse or vandalism and the opening looks clean, but the door has to be prepped for it, which makes it a new-door or factory-prepped choice rather than a quick retrofit. Surface vertical rod or a mortise device with exposed hardware is easier to add to an existing door. If you only need a mortise exit device on a hollow metal leaf with no vertical rods at all, wide stile options include the Von Duprin 9875, the Falcon 25-M-EO, or the Detex 30 Series Advantex.
11) What is the simplest mortise exit device if I do not need the lever trim and electric options the Sargent AD8640 offers?
The AD8640 can be ordered with ET lever trim in eight lever designs or as device only, plus alarm, monitoring and electric dogging options. For a plain push rail with no outside trim, the BEST Precision 2301 Series is an exit only mortise device with heavy wrought construction, the Falcon 25-M-EO is a Grade 1 wide stile exit only device, and the Detex 30 Series Advantex is a Grade 1 device only configuration.
12) Is the Von Duprin 9875 a direct swap for the Sargent AD8640?
Not a direct swap. Both are Grade 1 devices, but the AD8640 is a dummy function wide stile concealed vertical rod device with a touchpad rail and handing specified RHR or LHR. The Von Duprin 9875 is a smooth case wide stile mortise exit device, 3 ft, Grade 1 and non-handed, for 1-3/4 inch doors and not wood door compatible. The concealed vertical rod door and frame prep for the AD8640, including its 650 top strike and 606 bottom strike, differs from a mortise lock device prep.
13) My spec calls for a non-handed mortise exit device - does the Sargent AD8640 qualify?
No. The AD8640 requires handing at the time of order, either RHR right hand reverse or LHR left hand reverse. If the spec or your stocking plan calls for a non-handed or field reversible device, the Von Duprin 8875 wide stile crossbar mortise device is non-handed and the Von Duprin 9875 smooth case wide stile device is non-handed, both Grade 1. The Von Duprin 5575 narrow stile crossbar device is field reversible.
14) For a high abuse opening, is there a mortise exit device with a recessed pad rather than the Sargent AD8640 rail?
The AD8640 uses a projecting touchpad rail with 3 inch neutral projection and 2-1/8 inch depressed projection. Where a flush or recessed actuator is wanted, the Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad. The BEST Precision 2301 Series is another heavy duty choice, described with heavy wrought construction in an exit only configuration.
15) What finishes can I get to match the rest of the doors in my building?
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 and WSP white suede powder coat. 32D satin stainless is the usual match for commercial hollow metal openings.
16) What is the difference between a crossbar mortise exit device and the Sargent AD8640?
The AD8640 is a wide stile concealed vertical rod device with a factory cut push rail in E, F, J or G lengths covering 24 inch to 48 inch doors. The Von Duprin 8875 is a wide stile crossbar mortise exit device at 36 inches, Grade 1 and non-handed, and the Von Duprin 5575 is a narrow stile crossbar mortise device at 3 ft. A crossbar actuator spans the door on brackets rather than presenting a full width touchpad rail, so the door face prep and the look on the push side are different.
17) I only need one door width - is the Sargent AD8640 sized differently than the comparable devices?
The AD8640 is ordered in 32 inch, 36 inch, 42 inch and 48 inch sizes, with rails factory cut so no field cutting is required. Several comparables are offered at a single length instead: the Falcon 25-M-EO is a 36 inch wide stile device at 3 FT, the Von Duprin 8875 is 36 inches, and both the Von Duprin 9875 and 5575 are 3 ft. If your openings vary in width, the four AD8640 sizes cover them without cutting.
