Sargent 8343E 10BE – Frequently Asked Questions

1) What does classroom function mean on the Sargent 8343 mortise exit device?
On the Sargent 8343, classroom function means the outside lever is locked or unlocked by key, and when locked the lever freewheels instead of binding. Push the pad from inside and you always get out, regardless of how the outside is set. That is the standard setup for a classroom door where staff control entry from the corridor but egress is never restricted.
2) Will the Sargent 8343 fit a narrow stile aluminum storefront door?
Yes. The 8343 is built as a narrow stile device, so it suits aluminum storefront and other doors where there is not enough stile face for a wide stile chassis. If your openings are wide stile hollow metal or wood, a wide stile mortise device such as the Corbin Russwin ED5600AL or the Von Duprin 9875 is the better match.
3) Do I have to specify handing when ordering the Sargent 8343?
Yes, handing is required and there is no field-reversible option here. Pick RHR (right hand reverse) or LHR (left hand reverse) based on the door as it swings out toward you. If you need a device you can hand in the field, the Von Duprin 5575 narrow stile crossbar mortise device is listed as field reversible.
4) What device lengths does the Sargent 8343 come in, and which do I order for a 36 inch door?
Four rail lengths are offered: 32, 36, 42 and 48 inches. Order the length to match the door width, so a 36 inch leaf takes the 36 inch device. Note that if you add the AL alarmed option, the door has to be at least 36 inches wide.
5) Does the Sargent 8343 come with outside trim or do I order the lever separately?
Trim is a choice on the order. You can take the device on its own (exit only, no outside operation) or add ET trim in A, B, E, F, J, L, P or W lever designs. For classroom use you need a lever, since the whole point of the function is key controlled entry from the outside.
6) What other narrow stile mortise exit devices compare to the Sargent 8343?
The Sargent 8343 is a narrow stile mortise exit device rated ANSI/BHMA Grade 1. Two other narrow stile mortise devices are the Adams Rite 8400 Series, a Grade 1 life-safety narrow stile mortise device for aluminum doors that is not fire rated, and the Von Duprin 5575-3ft, a Grade 1 narrow stile crossbar mortise device in a 3 ft size, field reversible, for 1-3/4 inch doors and not fire rated. The 8343 uses a push rail with ET lever trim rather than a crossbar, and it is handed at order as RHR or LHR.
7) The opening is a wide stile hollow metal door - what mortise exit device should be used instead of the Sargent 8343?
The Sargent 8343 is built for narrow stile doors, so a wide stile opening calls for a wide stile mortise device. Wide stile Grade 1 options include the Von Duprin 9875-3FT smooth case non-handed device for 1-3/4 inch doors, the Von Duprin 8875-3FT crossbar device at 36 inches, the Falcon 25-M-EO exit only device for 1-3/4 inch doors, and the Corbin Russwin ED5600AL, which is 3 hour fire rated and accepts passage or classroom lever trim. The Adams Rite 8300 Series is another wide stile Grade 1 mortise device for wood and hollow metal doors.
8) Is the Sargent 8343 strong enough for a high traffic school corridor?
It is rated ANSI/BHMA Grade 1, the top commercial grade for cycle and strength testing, and Sargent builds the 8300 Series with modular components intended to serve the life of the building. That is the grade institutional specs call for on school and healthcare egress doors.
9) Mortise exit device or rim device for a classroom door with a narrow stile?
A mortise device like the 8343 puts the lock body inside the door edge, so the latching is concealed and the outside lever works through the mortise case. That takes a mortise pocket prepped in the stile. A rim device surface mounts and needs no pocket, which is easier on a retrofit but leaves the case on the door face. Choose the 8343 when the door is already mortise prepped or you are specifying new narrow stile leaves.
10) We only need free egress with no outside lever - is there a simpler alternative to the Sargent 8343?
The Sargent 8343 is a classroom function device, meaning the outside ET lever trim gives controlled access while egress stays free. If no outside trim is wanted, exit only mortise devices include the BEST Precision 2301 Series with heavy wrought construction, the Falcon 25-M-EO in a 36 inch wide stile 3 ft size for 1-3/4 inch doors, and the Detex 30 Series Advantex, a Grade 1 device only exit device for wide stile doors that is not wood door compatible. The 8343 itself can also be ordered with the trim option set to exit device only.
11) Is the Adams Rite 8400 a drop-in replacement for the Sargent 8343?
Both are Grade 1 narrow stile mortise exit devices, but they are not interchangeable. The Adams Rite 8400 Series is a life-safety narrow stile mortise device for aluminum doors and is not fire rated, while the Sargent 8343 is a classroom function device with freewheeling ET lever trim offered in RHR and LHR handing, 32, 36, 42 and 48 inch device sizes, and finishes from bright brass through satin stainless and black or white suede powder coat. Door prep, trim mounting and strike differ between the two, so treat a swap as a new prep rather than a retrofit.
12) Which mortise exit devices can go on a wood door if the Sargent 8343 opening changes to wood?
Among wide stile mortise devices, the Adams Rite 3300 Series and Adams Rite 8300 Series are both described for wood and hollow metal doors, the 3300 fire rated and the 8300 life-safety non fire rated, both Grade 1. The Detex 30 Series, Von Duprin 8875-3FT and Von Duprin 9875-3FT are listed as not wood door compatible. The Sargent 8343 is a narrow stile device, so a wood door in a wide stile frame points toward the Adams Rite options.
13) The Sargent 8343 is handed - is there a non-handed mortise exit device alternative?
The Sargent 8343 is ordered as RHR or LHR. If a non-handed or field reversible device suits the job better, the Von Duprin 9875-3FT and Von Duprin 8875-3FT are both non-handed Grade 1 wide stile mortise devices at 36 inches, and the Von Duprin 5575-3ft is a field reversible Grade 1 narrow stile device. Stile width still governs which of those will actually fit the door.
14) Does the Sargent 8343 include the classroom lever trim, or is that ordered separately like on the Corbin Russwin ED5600AL?
The Sargent 8343 is ordered with the trim selected on the same line: ET trim in A, B, E, F, J, L, P or W lever styles, or exit device only if no trim is wanted. The Corbin Russwin ED5600AL is supplied exit only or for use with classroom or passage lever trim that is not included, so the trim is a separate item on that one. For a standardized classroom opening, selecting the ET lever style with the 8343 keeps it to a single part.
15) What finishes does the Sargent 8343 come in to match the rest of my doors?
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, 32 bright stainless, 32D satin stainless, plus BSP black and WSP white suede powder coat. For a school or office standardizing across openings, 32D satin stainless and BSP black are the usual choices on aluminum storefront.
16) Can I use the Sargent 8343 where I only need egress and no outside entry?
Yes, order it with the trim option set to device only and there is no outside operator at all. But if the opening never needs keyed entry, an exit only device is simpler to buy and maintain, for example the Falcon 25-M-EO or the BEST Precision 2301, both mortise exit only devices. Those are wide stile builds, so they suit hollow metal and wood rather than narrow aluminum stiles.
17) Is there a mortise exit device rated for impact or abusive traffic instead of the Sargent 8343?
For wide stile openings that see abuse, the Von Duprin 9475/9575 Impact Series is a Grade 1 mortise lock exit device with a recessed push pad, not fire rated. The Sargent 8343 is a narrow stile Grade 1 device from the 8300 Series with modular construction intended for commercial traffic, so the Impact Series is the alternative only where the door is wide stile.
