    Sargent 8904E 10BE – Frequently Asked Questions

    1) What does the nightlatch function on the Sargent 8904 mortise exit device actually do?
    Night latch means the door is always locked from the outside and always free to exit from the inside. Push the pad, you're out. From the outside there is no lever entry unless you add ET trim, and even then the outside trim on a night latch device is key-controlled rather than a free-turning handle. That's the function you want on a back door, a service entrance, or a stair discharge where staff leave all day but nobody walks in off the street. If you need people to enter with a lever during business hours, the 8904 is the wrong function in the 8900 family.
    2) Do I have to specify handing when ordering a Sargent 8904?
    Yes, and there is no field-reversible shortcut here. You pick RHR (right hand reverse) or LHR (left hand reverse) at the time of order. Stand outside the door: if it swings toward you and the hinges are on your right, it's RHR. Exit devices are always reverse bevel because they're on out-swinging egress doors. Get this wrong and the mortise case is prepped for the wrong side of the door. If you need a device you can hand in the field, the Von Duprin 8875 and 9875 wide stile mortise devices are listed as non-handed.
    3) Can the Sargent 8904 go on a 3 hour fire rated door?
    Yes. The 8904 carries a UL-cUL fire rating for openings up to 3 hours, which is what lets it go on a stair door or a rated corridor opening. One thing to watch on a rated opening: a fire rated exit device must not be dogged down, so the mechanical hold-open trick you'd use on a non-rated door is off the table. Among comparable mortise devices, the Adams Rite 3300 Series is also fire rated, while the Adams Rite 8300, Von Duprin 8875, 9875, 9475/9575 and 5575 are all listed as not fire rated.
    4) What door widths does the Sargent 8904 exit device cover?
    Four device lengths: 32, 36, 42 and 48 inches. Match the device to the door leaf width, not to the frame opening. The 36 inch size is the everyday commercial door; 42 and 48 inch cover the wider leaves you find on loading and equipment openings. One catch on the electric options, the AL alarmed option requires a 36 inch minimum door width, so a 32 inch leaf rules out the alarm kit.
    5) What is the closest equivalent to a Sargent 8904 from another brand?
    For a Grade 1 wide stile mortise exit device on a 3 hour rated opening, the Corbin Russwin ED5600AL is the nearest match, rated Grade 1, 3 hour fire rated, wide stile, for 1-3/4 inch doors, though it comes as exit only or takes passage or classroom lever trim rather than a night latch. The Adams Rite 3300 Series is another fire rated Grade 1 wide stile mortise device and it's listed for both wood and hollow metal doors. The Falcon 25-M-EO is Grade 1 wide stile for 1-3/4 inch doors but it's exit only, so no outside trim. Watch the fire rating column: Von Duprin's 8875, 9875, 9475/9575 wide stile mortise devices are all listed as not fire rated, so they don't substitute on a rated stair or corridor opening.
    6) The Sargent 8904 is a wide stile device - what mortise exit device fits a narrow stile aluminum door?
    The Sargent 8904 is built for wide stile doors, so it will not lay out on a narrow stile aluminum entrance. For that opening the Adams Rite 8400 Series is a narrow stile mortise exit device for aluminum doors, Grade 1, with no fire rating. The Von Duprin 5575-3ft is another narrow stile Grade 1 mortise device, crossbar style, field reversible, for 1-3/4 inch doors and no fire rating. Confirm the opening does not require a fire label before specifying either.
    7) Which of these mortise exit devices can go on a wood door?
    The Sargent 8904 is a wide stile mortise exit device offered in 32, 36, 42 and 48 inch sizes. Among wide stile mortise peers, the Adams Rite 3300 Series and Adams Rite 8300 Series are both built for wood and hollow metal doors, the 3300 fire rated and the 8300 not. Several others are specifically not wood door compatible: the Von Duprin 8875-3FT, the Von Duprin 9875-3FT and the Detex 30 Series Advantex. That distinction decides the specification before grade or function does, since all of those are Grade 1.
    8) Do any of the comparable mortise exit devices offer the same access control options as the Sargent 8904?
    The Sargent 8904 is ordered with 24VAC/DC operation and electric options including remote dogging and latch retraction, electric dogging, Electroguard, a latchbolt monitor switch, a signal switch in the rail, and an alarmed version that requires a 36 inch minimum door width. The wide stile mortise peers are catalogued as mechanical devices: the Falcon 25-M-EO and the Detex 30 Series Advantex are exit only, and the Corbin Russwin ED5600AL is exit only or takes passage or classroom lever trim. If the opening is tied to a card reader or a fire alarm interface, the 8904 is the one in this group ordered with that electrification built in.
    9) Does the Sargent 8904 come with outside lever trim or do I order that separately?
    Trim is a separate line on the order. You can take the device on its own (Exit Device Only) or add Sargent ET trim in eight lever designs: A, B, E, F, J, L, P and W. The lever letter is a style choice, not a function change, so pick the one that matches the levers already on the building. If the opening is exit only and nobody enters through it, skip the trim entirely and save the cylinder.
    10) Should I use a mortise exit device or a rim device on this opening?
    A mortise device puts the lock case inside the door edge, so the door has to be prepped for a mortise pocket. That's the trade: more prep, but the latching hardware is concealed in the door and the frame instead of sitting on the surface. Rim devices bolt to the door face and latch onto a surface strike, so they retrofit an unprepped door far more easily. Go mortise when the doors are already mortise prepped, when you're matching mortise hardware elsewhere in the building, or when the spec on the drawing calls for it. Go rim when you're replacing surface hardware on doors that have never been mortised. The 8900 Series is offered in rim, mortise, surface vertical rod and concealed vertical rod configurations, so you can stay in one family across a building and still pick the right type per opening.
    11) Is the Sargent 8904 tough enough for a high traffic entrance in a school or hospital?
    It's a Grade 1 device, the heaviest commercial rating in ANSI/BHMA, and Sargent states the 8900 Series exceeds Grade 1 cycle and strength testing. Grade 1 is the level a facility spec should call for on an entrance that gets hit thousands of times a week. Construction is modular, so worn components can be swapped rather than replacing the whole device, which matters more than the initial spec once you're maintaining a fleet of openings.
    12) Is a Von Duprin 8875 crossbar device a drop-in substitute for a Sargent 8904?
    They are both wide stile Grade 1 mortise exit devices, but they are not the same device on the door. The Von Duprin 8875-3FT is a crossbar style device, non-handed, for 1-3/4 inch doors with no fire rating. The Sargent 8904 is a touchpad rail device ordered handed as RHR or LHR, fire rated up to 3 hours, and available with 24VAC/DC electric options such as latch retraction and electric dogging. Swapping a crossbar device for a rail device changes the door face appearance and the mounting pattern, so plan on a full device change rather than a like-for-like exchange.
    13) What mortise exit device holds up in an abuse-prone opening like a school corridor or a loading area?
    The Sargent 8904 is a Grade 1 wide stile mortise device with modular construction and is offered in powder coat finishes including Black Suede and White Suede alongside stainless steel. If the concern is impact on the push pad itself, the Von Duprin 9475/9575 Impact Series is a wide stile Grade 1 mortise device with a recessed push pad, and the BEST Precision 2301 Series uses heavy wrought construction. The Von Duprin 9475/9575 carries no fire rating, so on a labeled opening the Sargent 8904 with its 3 hour rating is the one that keeps the door compliant.
    14) What is the difference between the Adams Rite 3300 and 8300 mortise exit devices when replacing a Sargent 8904?
    Both Adams Rite series are Grade 1 wide stile mortise exit devices for wood and hollow metal doors, which puts them in the same family as the Sargent 8904 wide stile mortise device. The 3300 Series is fire rated; the 8300 Series is a life-safety device with no fire rating. On a labeled opening that rules the 8300 out, and the Sargent 8904 fire rated up to 3 hours or the Adams Rite 3300 is the correct direction. On an unlabeled egress door either Adams Rite series applies.
    15) What finishes does the Sargent 8904 come in for matching existing building hardware?
    Twelve finishes, covering the usual commercial palette and then some. Brass and bronze: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B oil rubbed dark oxidized satin bronze, plus 10BE and 10BL dark oxidized variants and 20D dark statuary bronze lacquered. Stainless: 32 bright and 32D satin, with 32D being the workhorse on commercial openings. If you're matching painted storefront or a dark scheme, BSP black suede and WSP white suede powder coat are the two painted options.
