Sargent 8344E 10BE – Frequently Asked Questions

1) What does the night latch function on the Sargent 8344 exit device actually do?
Night latch means free egress from the inside at all times, and outside access by key only. The 8344 is a Sargent 8300 Series mortise exit device set up for controlled entry: push the pad and you are out, but anyone coming in from the outside needs the key in the cylinder. It is the usual choice for back-of-house, service, and after-hours entrances where you do not want a lever that unlocks the opening.
2) Will a Sargent 8344 fit a narrow stile aluminum storefront door?
Yes, that is what it is built for. The 8344 is a narrow stile device, so the case and mounting are sized for the slim vertical rail on aluminum and glass storefront doors where a wide stile device will not land. If your door has a wide stile, you are better served by a wide stile mortise device such as the Corbin Russwin ED5600AL or the Von Duprin 9875.
3) Do I have to specify handing when ordering the Sargent 8344?
Handing is required, and there is no field-reversible option here. You pick either RHR (right hand reverse) or LHR (left hand reverse) at the time of order. Stand outside the door: if the hinges are on your right and the door swings toward you, it is right hand reverse. Get it wrong and the device will not work on the opening.
4) What device length do I order for a 36 inch wide door?
The 8344 comes in 32, 36, 42, and 48 inch sizes, and you match the size to the door width, not to the frame opening. A 36 inch door takes the 36 inch device. Wider doors up to 48 inches are covered by the 42 and 48 inch rails. Note that if you add the AL alarmed option, the door has to be at least 36 inches wide, so the 32 inch device and AL do not go together.
5) What is the closest narrow stile mortise exit device to the Sargent 8344 from another manufacturer?
The two narrow stile mortise alternatives are the Adams Rite 8400 Series life-safety narrow stile mortise exit device for aluminum doors and the Von Duprin 5575-3ft narrow stile crossbar mortise lock exit device, which is Grade 1 and field reversible in a 3 ft size. Both share the Sargent 8344's narrow stile format. The differences are in operation and handing: the 8344 is a push rail device ordered as RHR or LHR handing, while the Von Duprin 5575 uses a crossbar and is field reversible. Neither the Adams Rite 8400 nor the Von Duprin 5575 is fire rated.
6) Does the Sargent 8344 work on a fire rated opening, and what should I use if it does not?
The Sargent 8344 is a night latch function device, and night latch trim is a keyed-outside-access function rather than a fire exit hardware function. For a labeled opening, the fire rated mortise devices are the Adams Rite 3300 Series, which is fire rated and Grade 1 for wood and hollow metal doors, and the Corbin Russwin ED5600AL, a Grade 1 3 hour fire rated mortise device for 1-3/4 inch doors. Both are wide stile. The Adams Rite 8400 and 8300 Series and the Von Duprin 5575, 8875, 9875 and 9475/9575 are all listed as not fire rated.
7) The opening is a wide stile hollow metal door - is the Sargent 8344 still the right mortise exit device?
No. The Sargent 8344 is built as a narrow stile device for doors with limited stile width. For a wide stile opening, wide stile mortise devices include the Von Duprin 9875-3FT smooth case, the Von Duprin 8875-3FT crossbar, the Von Duprin 9475/9575 Impact Series with recessed push pad, the Detex 30 Series Advantex, the Falcon 25-M-EO exit only, and the Corbin Russwin ED5600AL. All are Grade 1. Note that the Von Duprin 9875, 8875 and Detex 30 are listed as not wood door compatible, while the Corbin Russwin ED5600AL and the Adams Rite 3300 and 8300 Series are stated for wood and hollow metal doors.
8) Can I add a lever on the outside of a Sargent 8344, or is it key only?
You can order it either way. Trim options run ETA, ETB, ETE, ETF, ETJ, ETL, ETP, and ETW ET lever trims, or None if you want the device only. With night latch function the outside control is key operated, so the ET trim you choose is mainly about the lever design matching the rest of your openings. If you already have ET trim on the door, order the device with None.
9) Is the Sargent 8344 strong enough for a high traffic school or hospital entrance?
It is rated ANSI/BHMA Grade 1, the top commercial grade for cycle and strength testing, and it is a commercial-duty device rather than a light duty one. Grade 1 is the level typically specified for schools, healthcare, and government openings that see continuous use.
10) Is the Sargent 8344 a mortise device or a rim device, and does that matter for my door prep?
Mortise. The latch case pockets into the edge of the door and works with a mortise lock prep, rather than sitting on the face of the door like a rim device with a surface strike. That means the door has to be prepped for a mortise case, so it is a straightforward swap if you are replacing an existing mortise exit device but a bigger job if your door is currently rim-prepped.
11) I only need free egress with no outside trim - is there a simpler device than the Sargent 8344?
Yes. The Sargent 8344 is a night latch function device and can be ordered with ET lever trim or as exit device only. If the opening never needs outside access, exit only mortise devices include the Falcon 25-M-EO, a Grade 1 wide stile exit only device in a 3 ft length for 1-3/4 inch doors, the Detex 30 Series Advantex configured as device only exit only, and the BEST Precision 2301 Series mortise exit device, exit only with heavy wrought construction. All three are wide stile or wide stile family devices, so they do not substitute on a narrow stile aluminum door.
12) Can I substitute the Adams Rite 8400 for a Sargent 8344 on an aluminum storefront door?
Both are narrow stile mortise exit devices, so the stile format matches, but they are not drop-in equals. The Sargent 8344 is a night latch function device offered in 32, 36, 42 and 48 inch device sizes with ET lever trim options and electric options such as alarmed, latchbolt monitor switch, electric dogging and remote latch retraction. The Adams Rite 8400 Series is a life-safety narrow stile mortise device for aluminum doors and is not fire rated. Confirm existing door and frame mortise prep before swapping, since prep is manufacturer specific.
13) What is the difference between the Sargent 8344 and the Adams Rite 8300 Series, since both are called 8300?
The series numbers overlap but the products do not. The Sargent 8344 is a narrow stile mortise exit device in Sargent's 8300 Series with night latch function. The Adams Rite 8300 Series is a life-safety mortise exit device for wood and hollow metal doors, Grade 1, and wide stile, and is not fire rated. If a spec calls out 8300, confirm the manufacturer before ordering, because stile type and door material differ between the two.
14) Is a crossbar mortise device like the Von Duprin 5575 interchangeable with the Sargent 8344?
They serve the same narrow stile mortise opening but present differently. The Sargent 8344 is a push rail device ordered by handing as RHR or LHR, with finishes ranging from bright brass and satin bronze through satin stainless and black or white suede powder coat. The Von Duprin 5575-3ft is a narrow stile crossbar mortise lock exit device, Grade 1, field reversible, for 1-3/4 inch doors and is not fire rated. Choose the crossbar only if you are matching existing crossbar hardware on adjacent doors, since the push rail and crossbar look and mounting footprint are not the same.
15) Do I have to specify handing on the Sargent 8344, or can I order a non-handed mortise exit device instead?
The Sargent 8344 requires handing at order as RHR or LHR. If the job needs stock that can be set in the field, the Von Duprin 5575-3ft narrow stile crossbar device is field reversible, and the wide stile Von Duprin 8875-3FT and 9875-3FT are non-handed. All three are Grade 1. Keep in mind the 8875 and 9875 are wide stile and listed as not wood door compatible, so they do not cover a narrow stile opening.
16) What finishes does the Sargent 8344 come in if I need it to match existing storefront 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, 32 bright stainless, 32D satin stainless, plus BSP black suede powder coat and WSP white suede powder coat. For dark anodized aluminum storefront, 10B or BSP are the usual matches; for clear anodized, 32D.
17) Can I standardize on the Sargent 8300 Series across a building with different functions on different doors?
Yes. The 8344 is the night latch function within the Sargent 8300 Series mortise exit device family, and the series is modular, so components are interchangeable across the line and one set of spare parts and service procedures covers the openings. That is the practical case for standardizing a facility on the 8300 platform rather than mixing brands door to door.
