Sargent NB8715E 10BE – Frequently Asked Questions

1) Is the Sargent NB8715 handed, and do I have to specify left or right?
Handing is required on the NB8715. You pick either RHR (right hand reverse) or LHR (left hand reverse) when ordering, and it is not a field-reversible device. Stand outside the opening: if the door swings toward you and the hinges are on the right, it is RHR. If you want a device you can flip on site, the Von Duprin 5575 is field reversible and the Von Duprin 9875 and 8875 are non-handed.
2) What does passage function mean on a Sargent NB8715 exit device, and is it the right choice for my opening?
Passage function means the outside lever is always unlocked. Pull the lever from the corridor side and you get in, push the pad from inside and you get out. There is no key control and no locking of the outside trim. That suits a door you want to latch but never lock, a stair discharge or an interior cross-corridor opening. If you need the outside lever locked and released by key, passage is the wrong function and you want a night latch or classroom version instead. The Corbin Russwin ED5600AL is the comparable device that takes either a passage or a classroom lever trim.
3) Can a surface vertical rod exit device like the Sargent NB8715 be used on a pair of doors with no mullion?
That is what vertical rod devices are for. The NB8715 latches vertically at the door edge rather than into a strike on the jamb, so a pair of doors can each carry a device and meet in the middle with no center mullion. A rim or mortise device latching into the frame needs either a mullion or a fixed inactive leaf. One thing to plan for on a pair: the NB8715 is a top latch configuration, so the securing point is at the head rather than into the floor.
4) What electrified options can I add to a Sargent NB8700 Series exit device for access control?
Seven electric options are orderable on the NB8715. For monitoring, the 53 latchbolt monitor switch reports whether the latch is secure, the 55 signal switch in the rail reports the pad being pushed, and the 54 internal micro switch sits in the ET trim. For remote control of the latch, 56 gives remote dogging or latch retraction and 58 gives electric dogging. The 59 Electroguard and the AL alarmed option cover the delayed egress and local alarm side, and AL carries a 36 inch minimum door width, so it will not go on a 32 inch leaf.
5) I need alarmed exit hardware on a 32 inch door, will the Sargent NB8715 AL option work?
No. The AL alarmed option carries a 36 inch minimum door width, so it cannot go on a 32 inch leaf. The device itself is fine at that width (the E Rail covers 24 to 32 inch doors) but you would need to handle the alarm separately rather than through the AL option. If the opening is a delayed egress application, the 59 Electroguard option is the other electrified route on this series.
6) Is the Sargent NB8715 fire rated?
The NB8715 is a Grade 1 device, and Grade 1 is a durability and strength rating under ANSI/BHMA, not a fire rating. The two are specified separately. If the opening on your drawing calls for a labeled fire door assembly, the Adams Rite 3300 Series is a fire rated Grade 1 wide stile mortise exit device for wood and hollow metal, and the Corbin Russwin ED5600AL is a Grade 1 three hour fire rated mortise exit device. Note that a fire exit device is never field dogged, so the dogging and electric dogging options do not belong on a fire opening.
7) I am replacing a Von Duprin 9875 mortise exit device, is the Sargent NB8715 a straight swap?
Not a straight swap, and you should not treat it as one. Both are Grade 1 wide stile devices, but the Von Duprin 9875 is a mortise lock device that latches into the frame, while the NB8715 is a surface vertical rod device latching at the head. Different door prep, different strike location. The closer like-for-like replacement of a 9875 from a different brand in our range is the Corbin Russwin ED5600AL, a Grade 1 wide stile mortise exit device, or the Falcon 25-M-EO exit only mortise device. Reach for the Sargent NB8715 when you are changing the latching approach, most often to get a pair of doors working without a mullion, or because you need the door thickness above 1-3/4 inches.
8) The opening is a narrow stile aluminum storefront door. What mortise exit device should be used instead of the Sargent NB8715?
The NB8715 is a wide stile device and needs 4-1/2 inch minimum stile with trim or 3-1/2 inch without, so it will not fit a narrow stile aluminum door. For that opening the Adams Rite 8400 is the direct answer: a Grade 1 narrow stile life-safety mortise exit device built for aluminum doors. The Von Duprin 5575-3ft is the other narrow stile Grade 1 mortise option, a crossbar device for 1-3/4 inch doors that is field reversible. Measure the stile face before ordering either.
9) Which mortise exit devices carry a fire rating for a labeled opening?
Two in this class are explicit about it. The Adams Rite 3300 Series is a fire-rated Grade 1 wide stile mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated wide stile mortise device for 1-3/4 inch doors. Several wide stile Grade 1 peers are life-safety rather than fire rated, including the Adams Rite 8300, the Von Duprin 8875, 9875 and 9475/9575. The Sargent NB8700 Series supports both fire-rated and standard openings, so confirm the label requirement before you pick the configuration.
10) What is the closest wide stile Grade 1 mortise exit device to the Sargent NB8715 that accepts passage lever trim?
The Corbin Russwin ED5600AL is the nearest match on function. It is a Grade 1 wide stile mortise exit device that can be used exit only or with classroom or passage lever trim, and it is built for 1-3/4 inch doors. The Sargent NB8715 is a Grade 1 wide stile passage function device that takes ET trim with A, B, E, F, J, L, P, or W levers, or ships as exit device only. If you are specifying a passage opening and want lever trim on the outside, both cover that role; the Sargent is ordered with the ET lever style as part of the device, while the Corbin Russwin lever trim is a separate line item.
11) Is a Von Duprin 8875 or 9875 a drop-in replacement for a Sargent NB8715?
They are close on paper and different in the door. The Von Duprin 8875-3FT is a wide stile Grade 1 crossbar mortise exit device, 36 inch, non-handed, for 1-3/4 inch doors, and the 9875-3FT is the smooth case wide stile Grade 1 version, also non-handed and 1-3/4 inch. Both are mortise lock devices and neither is wood door compatible. The Sargent NB8715 is a surface vertical rod device with a top latch, handed as RHR or LHR, for wood or metal doors 1-3/4 inch to 2-1/4 inch thick. Swapping between them changes the door prep and the latching hardware at the head, so treat it as a new install rather than a retrofit.
12) Can I get a Sargent NB8715 without the outside lever trim?
Yes. Trim is a separate choice and one of the options is exit device only, with no outside trim at all. That is the common spec for a stair discharge or an exterior door where nobody comes back in through it. If you do want a lever outside, the ET trim comes in eight lever designs: A, B, E, F, J, L, P and W. Remember the stile math changes with the choice, 4-1/2 inches of stile with trim versus 3-1/2 inches without.
13) Is the Sargent NB8715 heavy duty enough for a school or hospital main entrance?
It is a Grade 1 commercial device, which is the top ANSI/BHMA durability tier and what you want on a high-traffic entrance in a school, hospital or government building. Grade 1 is also what a spec writer usually requires on those facility types. If you are standardizing a campus, the whole NB8700 Series is Grade 1 and available in the same twelve finishes across 32, 36, 42 and 48 inch door widths, so one finish and one lever design can carry across openings of different sizes.
14) What exactly do I have to specify when ordering a Sargent NB8715?
Four things settle the order. Handing is required, RHR or LHR. Size follows the door width, 32, 36, 42 or 48 inches. Trim is either one of the eight ET lever designs (A, B, E, F, J, L, P, W) or exit device only. Finish is one of twelve. Electric options are optional and added on top: 53, 54, 55, 56, 58, 59 or AL. Get the handing and the door width right first, since those are the two that will not work if they are wrong.
15) What is the difference between the Sargent NB8715 and an exit only device like the Falcon 25-M-EO or BEST Precision 2301?
The Falcon 25-M-EO is a Grade 1 wide stile mortise device supplied exit only for 1-3/4 inch doors in a 36 inch, 3 foot size, and the BEST Precision 2301 is a mortise exit device, also exit only, with heavy wrought construction. Exit only means push pad inside, no outside trim and no outside operation. The Sargent NB8715 is a passage function device and can be ordered with ET lever trim in A, B, E, F, J, L, P, or W, or as exit device only. If anyone needs to come back in through that door without a key, you need the trim; if the opening is egress only, an exit only device covers it.
16) For a high abuse opening like a school corridor or a loading area, what is the alternative to a standard push pad exit device?
The Von Duprin 9475/9575 Impact Series is the abuse-oriented choice in this group: a Grade 1 wide stile mortise lock exit device with a recessed push pad, which keeps the pad out of the path of carts and impact. The Detex 30 Series Advantex is a Grade 1 wide stile mortise device supplied exit only and not wood door compatible, so it suits a metal door on an egress-only opening. The Sargent NB8715 is a Grade 1 passage function device for wood or metal doors in commercial use, with rail options covering 24 inch to 48 inch door widths and no cutting required.
17) Does the door need to be handed when ordering a mortise exit device, and which ones avoid that?
The Sargent NB8715 is ordered handed, RHR or LHR, so the swing has to be confirmed before the order goes in. If handing is a risk on the job, the Von Duprin 8875-3FT and 9875-3FT are non-handed wide stile Grade 1 mortise devices, and the Von Duprin 5575-3ft is field reversible, a narrow stile Grade 1 device for 1-3/4 inch doors. Non-handed and field reversible devices let one part number cover both swings across a building.
18) Which mortise exit device should be used on an aluminum storefront that also needs a fire label?
For a labeled opening in wood or hollow metal, the Adams Rite 3300 Series is the fire-rated Grade 1 wide stile mortise device. The Adams Rite 8400 Series is the narrow stile Grade 1 device for aluminum doors, and it is a life-safety device rather than fire rated, as is the Adams Rite 8300 wide stile. Sort the opening first: if it is a labeled door, the fire rating decides the device, and if it is an aluminum storefront the stile width does. The Sargent NB8715 is the wide stile Grade 1 surface vertical rod option once the door is wood or metal at 1-3/4 inch to 2-1/4 inch.
19) What finishes does the Sargent NB8700 Series exit device come in, and which hold up outdoors?
Twelve finishes. Brass and bronze: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, and 20D dark statuary bronze lacquered. Stainless: 32 bright and 32D satin. Powder coat: BSP black suede and WSP white suede. For an exterior opening or a coastal building, 32D satin stainless is the usual pick, and the suede powder coats give you black or white without a lacquer to wear off. 10B oil rubbed is a living finish and will change with handling.
20) What is the difference between a push pad exit device and a crossbar one when replacing an existing device?
The Von Duprin 8875-3FT and 5575-3ft are crossbar mortise exit devices, a horizontal bar across the door face, Grade 1, for 1-3/4 inch doors. The Von Duprin 9875-3FT is the smooth case push style in the same wide stile Grade 1 class, and the Von Duprin 9475/9575 uses a recessed push pad. The Sargent NB8715 is a surface vertical rod device with rail lengths for 24 inch to 48 inch doors. If a facility is standardizing the look across corridors, the bar versus pad choice is what people notice from the hallway, and it does not change the Grade 1 rating on any of them.
