Sargent AD8674E 10BE – Frequently Asked Questions

1) Will the Sargent AD8674 exit device fit my door, and what door thickness and stile width does it need?

The AD8674 needs a hollow metal door at least 1-3/4 inches thick, with a thickness range up to 2-1/4 inches, and a minimum stile width of 4-1/2 inches. Door widths from 24 to 48 inches are covered by four factory-cut rails: E rail for 24 to 32 inch doors, F rail for 33 to 36 inches, J rail for 37 to 42 inches, and G rail for 43 to 48 inches. If your opening is an aluminum storefront door with a stile narrower than 4-1/2 inches, this is the wrong device for it.

2) What does fail secure mean on the Sargent AD8674, and can people still get out if the power drops?

Fail secure means the outside trim stays locked when power is removed, so a power loss leaves the door secured from the outside rather than free. Egress is unaffected either way: pushing the touchpad from the inside always retracts the latches, which is what keeps the opening code compliant for emergency egress. If your application requires the outside to unlock on power failure (a stair re-entry door on a fire alarm release, for example), you want a fail safe device instead, not the AD8674.

3) Do I have to specify handing when ordering the Sargent AD8674 concealed vertical rod device?

Handing is required on the AD8674, and it is not field reversible on the order form: you pick either RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always reverse bevel, so stand outside the opening, see which side the hinges are on, and order to that. Getting it wrong on a concealed vertical rod device is not a quick swap, since the rods and top and bottom latching are built into the door.

4) Can I use the Sargent AD8674 on a fire rated opening?

Yes, in the fire rated configuration. The AD8674 is ordered either as standard or as fire rated less dogging, and the fire rated version has no mechanical dogging because a fire door has to relatch on every swing. Standard 650 top strike and 606 bottom strike are supplied for panic and fire rated performance. If you need to hold the latches retracted during business hours on the fire rated version, that has to be done electrically rather than with a dogging key.

5) What electric options can I add to a Sargent AD8674, and which one do I need for a request-to-exit signal or remote unlocking?

Seven electric options are available on the AD8674. For a request-to-exit signal back to the access control panel, order 55 (signal switch in rail). To know the latch is actually thrown, order 53 (latchbolt monitor switch). For remote latch retraction or dogging from the security desk, order 56 (remote dogging / latch retraction) or 58 (electric dogging). 54 puts an internal micro switch in the ET control for outside lever monitoring, 59 is Electroguard, and AL adds the local alarm. Note the AL alarmed option requires a door at least 36 inches wide.

6) What is the closest equivalent to a Sargent AD8674 mortise exit device from Von Duprin?

The Von Duprin 9875-3FT is the nearest Von Duprin mortise exit device: a 3 ft smooth case wide stile mortise exit device, Grade 1 and non-handed. The Sargent AD8674 is also Grade 1, but it is an electrified fail secure device and must be ordered handed, RHR or LHR, with a 12V or 24V coil. If the opening needs the access control tie-in, the AD8674 carries it; if the opening only needs mechanical egress, the 9875-3FT covers the same wide stile mortise application. The 9875-3FT lists a 1-3/4 inch door thickness and is not wood door compatible.

7) My door is a narrow stile aluminum storefront. Will the Sargent AD8674 work, or do I need something else?

The Sargent AD8674 is built for a 4-1/2 inch minimum stile width on hollow metal doors 1-3/4 inch to 2-1/4 inch thick, which is a wide stile prep. For an aluminum storefront, the Adams Rite 8400 Series is a narrow stile mortise exit device specifically for aluminum doors, Grade 1. The Von Duprin 5575-3ft is also a narrow stile mortise lock exit device, Grade 1, field reversible, at 1-3/4 inch door thickness. Both are mechanical, so an aluminum opening that also needs access control will need the electrified function supplied elsewhere on the opening.

8) I only need mechanical egress on a mortise exit opening, no access control. What is a simpler device than the Sargent AD8674?

For a mechanical-only mortise exit opening, the Falcon 25-M-EO is an exit only Grade 1 wide stile mortise device listed at 1-3/4 inch door thickness in a 36 inch, 3 ft size. The BEST Precision 2301 is likewise an exit only mortise device with heavy wrought construction. Both drop the electrified side entirely. The Sargent AD8674 is the electrified fail secure route, with 12V and 24V coils and options such as 53 latchbolt monitor, 55 signal switch in rail, and 56 remote dogging / latch retraction. Choose the exit only devices when nothing on the opening reports to a panel.

9) The opening is a fire rated door. Which mortise exit device should I use instead of a standard one?

The Adams Rite 3300 Series is a fire-rated mortise exit device for wood and hollow metal doors, Grade 1 and wide stile. The Sargent AD8674 is ordered with a Rating selection of Standard or Fire Rated (Less Dogging), so a fire opening takes the Fire Rated (Less Dogging) build, which removes mechanical dogging as fire doors require. Note that the Adams Rite 8300 Series and 8400 Series and the Von Duprin 5575, 8875, 9475/9575 and 9875 devices are all listed with a fire rating of No, so they belong on non-rated openings.

10) Which of these mortise exit devices accept lever trim and which are exit only?

The Sargent AD8674 is ordered with a Trim Option, either ET Trim in A, B, E, F, J, L, P or W lever, or None for exit device only. The Corbin Russwin ED5600AL is exit only or for use with classroom or passage lever trim, which is not included. On the other side, the Falcon 25-M-EO is exit only, the BEST Precision 2301 is exit only, and the Detex 30 Series is a device only, exit only build. If the outside of the door needs a lever, the AD8674 with ET trim or the ED5600AL with separately ordered trim are the two paths.

11) What voltage does the Sargent AD8674 electrified exit device need?

The AD8674 is ordered as either 12V or 24V, and you specify it up front, so match it to the power supply and access control panel you already have on the job before you order. Both are available across the device, and the choice is on the order form rather than a field setting.

12) Should I use a concealed vertical rod device or a rim device with a mullion on my pair of doors?

A concealed vertical rod device like the AD8674 latches into the head frame and the threshold, so a pair of doors can be secured with no center mullion and the full opening stays clear. That matters for moving beds, carts, or freight. The rods run inside the door leaf, so nothing is exposed to damage or vandalism, but the door has to be prepped for them, which makes this a specify-at-order item rather than a retrofit onto an unprepped door. If your pair already has a removable mullion and you want the simplest device and the easiest service, a rim device on each leaf is the less complicated answer.

13) What lever trim options come with the Sargent AD8674, or can I order the device by itself?

ET trim is offered in eight lever designs on the AD8674: A, B, E, F, J, L, P, and W levers. You can also order the device alone with no trim, which is what you want on an exit only opening where nobody comes in from the outside. If you are matching lever style across a building, pick the ET lever that matches the Sargent levers already on your other openings.

14) What mounting height is the Sargent AD8674 set at, and can it be lowered for an elementary school?

Standard centerline is 41 inches from finished floor. A 38 inch centerline is available for elementary schools and for accessibility requirements where the touchpad needs to sit lower. Specify the 38 inch option at order if your drawings call for it, since it is a factory setting and not a field adjustment.

15) The opening needs a 3 hour fire rating on a wide stile door with lever trim. What are my options?

The Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device for wide stile doors at 1-3/4 inch thickness, usable exit only or with classroom or passage lever trim ordered separately. The Adams Rite 3300 Series is also fire-rated and Grade 1 wide stile, for wood and hollow metal doors. The Sargent AD8674 covers the fire opening through its Fire Rated (Less Dogging) build and takes ET lever trim in the same order, with the added fail secure electrified function if the opening is on access control.

16) Is a Von Duprin 8875 or 9475/9575 a drop-in substitute for a Sargent AD8674?

They are not equivalents, though all three are Grade 1 wide stile mortise exit devices. The Von Duprin 8875-3FT is a crossbar mortise exit device at 36 inches, non-handed, and the 9475/9575 Impact Series uses a recessed push pad. The Sargent AD8674 is a concealed vertical rod device with an electrified fail secure function, handed RHR or LHR, and is ordered in 32, 36, 42 and 48 inch sizes. A crossbar or recessed push pad device changes the look and the touch surface on the door and brings no electrified function, so it will not match an AD8674 already installed on adjacent leaves.

17) What is the difference between the Adams Rite 3300 and 8300 Series mortise exit devices?

Both are Grade 1 wide stile mortise exit devices for wood and hollow metal doors. The 3300 Series is fire-rated; the 8300 Series is a life-safety device with a fire rating of No, so it belongs on non-rated openings. That is the deciding split when replacing a Sargent AD8674 on a mixed set of openings where some leaves are rated and some are not.

18) Which mortise exit device is non-handed or field reversible so I do not have to specify hand?

The Von Duprin 8875-3FT and 9875-3FT are both non-handed, and the Von Duprin 5575-3ft is field reversible. The Sargent AD8674 is ordered handed, RHR or LHR, because of its electrified fail secure construction. For a property manager stocking spares across many openings, a non-handed device reduces what has to be held on the shelf; for an opening tied to an access control panel, the AD8674 handing is specified at order.

19) What finishes does the Sargent AD8674 exit device come in for matching existing hardware?

Twelve finishes are available on the AD8674: 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 powder coat and white suede powder coat. Satin stainless 32D is the usual match on commercial hollow metal openings, and the two suede powder coats are the ones to look at when the doors are painted and you want the device to disappear into them.

20) Is the Sargent AD8674 Grade 1, and is it heavy enough for a high traffic entrance?

Grade 1, which is the highest ANSI/BHMA durability grade and the level normally specified for commercial and institutional entrances. The AD8674 uses a stainless steel top bolt and a heavy center case, and it is a commercial device rather than a residential one. For standardizing across a facility, the AD8600 Series gives you the same platform in other electrified and mechanical functions.

21) I need a mortise exit device on a hollow metal opening with no wood leaves and heavy traffic. What are the heavy duty choices?

The Detex 30 Series Advantex is a Grade 1 wide stile mortise lock exit device listed as not wood door compatible, so it is a hollow metal choice, and it is a device only exit only build. The BEST Precision 2301 is an exit only mortise device with heavy wrought construction. The Sargent AD8674 is built for commercial hollow metal doors with a stainless steel top bolt and robust center case, and adds the electrified fail secure function the other two do not carry.
