Sargent 8340E 10BE – Frequently Asked Questions

1) What does the dummy function on the Sargent 8340 mortise exit device actually do?
It doesn't latch anything. The 8340 is a dummy device with freewheeling trim, meaning the push rail and the lever turn but operate no bolt. It is used to match the look of an active exit device on the inactive leaf of a pair or on a door that must not lock or latch. If you need a device that actually secures the opening, order an exit-only or lever-trim mortise device instead.
2) Will a Sargent 8340 fit an aluminum storefront door with a narrow stile?
Narrow stile is exactly what the 8340 is built for. The 8300 Series device in this configuration is engineered for doors with limited stile width, which is the situation on aluminum glass front doors. Wide stile mortise devices like the Von Duprin 9875 or Falcon 25-M-EO will not fit that same narrow vertical rail.
3) Can I get the Sargent 8340 with a lever trim to match the active leaf?
Yes. Trim choices are ET Trim in A, B, E, F, J, L, P and W lever designs, or you can order the device only with no trim. Because the function is dummy, the lever freewheels, so pick the lever style that matches the active device on the pair rather than choosing by function.
4) Is the Sargent 8340 a Grade 1 device for a high traffic entrance?
Grade 1, and Sargent states it exceeds the ANSI/BHMA Grade 1 requirements for cycle and strength testing. That is the top commercial durability tier, which is what an institutional spec normally calls for on a main entrance.
5) What is the closest narrow stile mortise exit device alternative to the Sargent 8340?
For a narrow stile aluminum door opening, the two closest peers to the Sargent 8340 are the Adams Rite 8400 Series, a Grade 1 narrow stile mortise exit device for aluminum doors, and the Von Duprin 5575-3ft, a Grade 1 narrow stile crossbar mortise exit device in a 3 ft size that is field reversible. The Sargent 8340 itself is a Grade 1 narrow stile mortise device in the 8300 Series, offered in 32, 36, 42 and 48 inch sizes, so it covers a wider size range than a fixed 3 ft device. The Von Duprin 5575 uses a crossbar actuator rather than a push rail, which changes the look of the opening.
6) The Sargent 8340 is narrow stile - what should I use on a wide stile wood or hollow metal door instead?
The Sargent 8340 is built for narrow stile openings, so on a wide stile wood or hollow metal door look at the Adams Rite 8300 Series, a Grade 1 wide stile mortise exit device for wood and hollow metal doors, or the Corbin Russwin ED5600AL, a Grade 1 wide stile mortise device for 1-3/4 inch doors that accepts passage or classroom lever trim. The Falcon 25-M-EO is another Grade 1 wide stile mortise device for 1-3/4 inch doors in an exit only configuration.
7) What looks like a substitute for the Sargent 8340 but will not give me the same dummy paired door result?
Devices catalogued as exit only will not reproduce what the Sargent 8340 does. The 8340 is a dummy function device with freewheeling trim, so the lever turns without operating a latch and the inactive leaf matches the active one visually. The BEST Precision 2301, the Falcon 25-M-EO and the Detex 30 Series are exit only devices with no lever trim, and the Corbin Russwin ED5600AL accepts passage or classroom lever trim, which is an operating function rather than a dummy one.
8) What device length do I order for a 36 inch door?
The 8340 comes in 32, 36, 42 and 48 inch rail lengths, so you size the device to the door leaf width. A 36 inch leaf takes the 36 inch device; 42 and 48 inch lengths cover wider leaves common on entrance pairs.
9) What is a simpler exit only mortise device if I do not need the lever trim the Sargent 8340 carries?
The Sargent 8340 is offered with ET lever trim in A, B, E, F, J, L, P and W lever styles, or as exit device only. If you want a device with no trim at all, the BEST Precision 2301 Series is an exit only mortise device with heavy wrought construction, the Falcon 25-M-EO is a Grade 1 exit only mortise device, and the Detex 30 Series Advantex is a Grade 1 device only, exit only configuration. All three are separate from the 8340 in that they are not dummy function with freewheeling trim.
10) Which of these mortise exit devices are not suitable for wood doors?
If the leaf is wood, the Detex 30 Series Advantex, the Von Duprin 8875-3FT and the Von Duprin 9875-3FT are all listed as not wood door compatible. Devices catalogued for wood and hollow metal include the Adams Rite 3300 Series and the Adams Rite 8300 Series. The Sargent 8340 is a narrow stile design intended for openings with limited stile width.
11) What is the difference between the Sargent 8340 and 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 and is not fire rated. The Sargent 8340 is a Grade 1 narrow stile mortise device in the 8300 Series, non-handed in design and supplied in 32, 36, 42 and 48 inch sizes with dummy function freewheeling trim. Stile width is the deciding factor: the Impact Series needs a wide stile leaf, the 8340 is made for limited stile width.
12) For a standardized aluminum storefront program, which mortise exit devices should I be comparing?
Narrow stile is the constraint on aluminum storefront. The Sargent 8340 is a Grade 1 narrow stile mortise device available in 12 finishes including 32D satin stainless steel, BSP black suede powder coat and WSP white suede powder coat, which helps match a storefront package. The Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device specifically for aluminum doors, and the Von Duprin 5575-3ft is a Grade 1 narrow stile crossbar mortise device. Wide stile devices such as the Von Duprin 8875-3FT will not fit a narrow stile aluminum leaf.
13) What finishes does the Sargent 8340 come in to match existing hardware in my building?
Twelve finishes: bright brass 03, satin brass 04, bright bronze 09, satin bronze 10, dark oxidized satin bronze in 10B oil rubbed, 10BE and 10BL clear coated, dark statuary bronze 20D, bright stainless 32, satin stainless 32D, plus black suede BSP and white suede WSP powder coat. 32D satin stainless and the suede powder coats are the usual matches on aluminum storefront.
