Sargent MD8673E 10BE – Frequently Asked Questions

1) What door widths does the Sargent MD8673 exit device cover?
Doors from 24 to 48 inches wide. Device sizes run 32, 36, 42 and 48 inches, and the rails come in four sizes (E, F, J, G) factory-cut to your specific door width, so the door dimension has to be right on the order. Openings up to 120 inches tall are accommodated.
2) What does fail safe mean on the Sargent MD8673, and what happens in a power failure?
Fail safe means the device unlocks when power is removed. Drop power, whether by a fire alarm relay, an access control release, or an outage, and the outside trim is free to enter. If you need the opening to stay secure on a power loss, fail safe is the wrong choice and you want a fail secure electrified function instead. Egress from the inside is always available through the push rail regardless of power.
3) Do I need a mullion to use the Sargent MD8673 on a pair of doors?
No. The MD8673 is a concealed vertical rod device, so it latches into a top strike at the head and a bottom strike at the threshold rather than into a strike on the opposite leaf. That is what lets it secure a pair of doors with a clear opening and no center mullion. A rim device on the same pair would need a mullion between the leaves.
4) Can the Sargent MD8673 be used on a fire rated opening?
Yes. A fire rated version is orderable, and it comes less dogging, because a fire door has to relatch on every swing. The strike set is rated for panic and fire use: 650 top strike and 606 bottom strike. If you order the standard rating instead, that is the non-fire configuration.
5) What do I have to specify when ordering a Sargent MD8673?
Four things are required: handing (RHR or LHR), voltage (12V or 24V), rating (standard or fire rated less dogging), and door width so the rail is cut correctly. Then choose a finish and decide on trim. Electric options are add-ons rather than required, but if you want any of them, they go on the same order.
6) Is the Sargent MD8673 handed, and can I reverse it in the field?
Handing is specified at order: RHR (right hand reverse) or LHR (left hand reverse). Stand outside the opening, and note that exit devices are always described in the reverse hands because the door swings out toward you for egress. If you want a device you can flip on site, the Von Duprin 5575 narrow stile crossbar mortise device is field reversible.
7) How does the Sargent MD8673 tie into an access control system?
Remote latch retraction is the core of it. Energize the device from the card reader or front desk and the latches pull back, so the door pushes open freely for scheduled unlock periods, then relatches when power drops. That is the 56 remote dogging / latch retraction option. If you want electric dogging only, that is option 58. For monitoring, 53 is a latchbolt monitor switch, 55 is a signal switch in the rail, and 54 is an internal micro switch in the ET control. Delayed egress and Electroguard (59) are available where the code official permits them.
8) What is the closest equivalent to the Sargent MD8673 if the opening is a narrow stile aluminum door?
The MD8673 is a Grade 1 mortise exit device built for narrow stile openings, so the narrow stile peers are the ones to look at. The Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device for aluminum doors, and the Von Duprin 5575-3ft is a Grade 1 narrow stile crossbar mortise lock exit device that is field reversible. The MD8673 itself is specified for hollow metal doors and carries fail-safe electrified operation with remote latch retraction, which neither of those two peers lists, so the swap holds on stile and grade rather than on the electric function.
9) Which mortise exit devices work on wood doors if the Sargent MD8673 does not suit the opening?
The MD8673 is engineered for hollow metal doors. Where the leaf is wood, the Adams Rite 3300 Series and the Adams Rite 8300 Series are both Grade 1 mortise exit devices for wood and hollow metal doors, the 3300 fire rated and the 8300 not. Note that the Detex 30 Series, the Von Duprin 8875-3FT and the Von Duprin 9875-3FT are each specified as not wood door compatible, so they are not options on a wood leaf.
10) What mortise exit device should be used instead of the Sargent MD8673 on a wide stile door?
The MD8673 is specified as narrow stile, so a wide stile opening calls for a different device. The Von Duprin 9875-3FT is a Grade 1 smooth case wide stile mortise exit device that is non-handed, the Von Duprin 8875-3FT is a Grade 1 wide stile crossbar mortise device, also non-handed, and the Falcon 25-M-EO is a Grade 1 wide stile mortise exit device in exit only function for 1-3/4 inch doors. The Corbin Russwin ED5600AL is a Grade 1 wide stile mortise device for 1-3/4 inch doors that accepts passage or classroom lever trim.
11) Is there a simpler mortise exit device than the Sargent MD8673 for an opening that does not need access control?
Yes. The MD8673 carries an electrified fail-safe function with remote latch retraction, which only earns its keep where the door ties into an access control system. Where the door just needs to open, a mechanical exit only device covers it: the Falcon 25-M-EO is a Grade 1 mortise exit device in exit only function, the BEST Precision 2301 is a mortise exit device in exit only with heavy wrought construction, and the Detex 30 Series Advantex is a Grade 1 mortise lock exit device supplied as device only, exit only. None of those three requires power or wiring at the door.
12) Which mortise exit devices are fire rated as an alternative to the Sargent MD8673?
The MD8673 can be ordered in a fire rated, less dogging configuration alongside the standard configuration. Among the alternatives, the Adams Rite 3300 Series is a fire rated Grade 1 mortise exit device for wood and hollow metal doors. Several of the other mortise devices are specified as not fire rated, including the Adams Rite 8300 Series, the Adams Rite 8400 Series, the Von Duprin 5575-3ft, the Von Duprin 8875-3FT, the Von Duprin 9475/9575 Impact Series and the Von Duprin 9875-3FT, so those do not carry over to a labeled opening.
13) Can a Von Duprin 5575 be used in place of a Sargent MD8673 on the same opening?
They share narrow stile geometry and a Grade 1 rating, but they are different devices. The Von Duprin 5575-3ft is a narrow stile crossbar mortise lock exit device, field reversible, specified for 1-3/4 inch doors and not fire rated. The Sargent MD8673 is a concealed vertical rod device with a touchpad rail, ordered by handing as RHR or LHR, in a fail-safe electrified function with remote latch retraction, and it is available in a fire rated configuration. A crossbar device and a concealed vertical rod device do not use the same door prep or the same strikes, so this is a redesign of the opening rather than a drop-in swap.
14) Does the Sargent MD8673 come with outside lever trim?
Not unless you add it. The device can be ordered exit only, or with ET trim in eight lever designs: A, B, E, F, J, L, P and W. Pick the lever that matches the rest of the building. If you already stock ET trim, the device will take it.
15) Can I mount the Sargent MD8673 lower for an elementary school?
Yes. Standard push rail centerline is 41 inches from finished floor, with a 38 inch option meant for elementary schools and accessibility. Specify the height with the order, since it affects how the concealed rods are cut.
16) What is the difference between a concealed vertical rod exit device and a mortise exit device?
A mortise exit device latches sideways into the frame or into the other leaf from a lock case pocketed in the door edge, so it needs a mortise prep and, on a pair, a mullion or an active/inactive arrangement. A concealed vertical rod device like the MD8673 runs rods inside the door to latch top and bottom, which frees a pair of doors of any center post and leaves nothing exposed on the door face. Rod devices ask more of the installer at the head and the threshold; mortise devices are simpler on a single door. Exit only mortise options ZenSupply carries include the Falcon 25-M-EO and the BEST Precision 2301.
17) Should I run 12V or 24V to the Sargent MD8673?
Both are offered, so match whatever your existing power supply and access control panel run. On a latch retraction device the inrush current matters, so size the supply for the device rather than assuming a door strike supply will carry it. Verify voltage and current capacity before you pull wire, since the voltage is fixed at the time of order and is not field selectable.
18) I don't need electrified operation. What is a simpler mortise exit device for a hollow metal door?
If the opening just needs mechanical egress with no access control tie-in, skip the electrified device. The Von Duprin 9875-3FT is a 3 foot smooth case wide stile mortise exit device, Grade 1 and non-handed, for 1-3/4 inch doors, and it is not for wood doors. The 8875-3FT is the crossbar version of the same idea. Both are non fire rated, so for a fire opening you need a rated device instead.
19) What is the difference between ordering a Sargent MD8673 with lever trim and buying a device that takes separate trim?
The MD8673 is ordered with the outside trim selected on the same line: ET Trim in A, B, E, F, J, L, P or W lever, or exit device only with no trim. 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 part number on the order. The Falcon 25-M-EO, the BEST Precision 2301 and the Detex 30 Series are each specified as exit only devices. For a facility standardizing lever style across a floor, the difference decides whether the lever comes on one line or two.
20) Does handing matter when substituting for a Sargent MD8673?
It does. The MD8673 is ordered by hand, RHR or LHR, so the substitute has to be handed to the opening as well or handled in the field. The Von Duprin 5575-3ft is field reversible, and the Von Duprin 8875-3FT and Von Duprin 9875-3FT are both non-handed, so those three can be pulled from stock without confirming the swing first. That matters most on a fleet order across a building where the swings are mixed.
21) Which mortise exit device stands up best to abuse in a high traffic or back of house opening compared with the Sargent MD8673?
The MD8673 is a Grade 1 device with stainless steel top bolt and a robust center case built for demanding commercial applications. Where the concern is impact on the pad itself, the Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad, and the BEST Precision 2301 is a mortise exit device with heavy wrought construction. Both of those are wide stile or exit only devices, so they suit a different opening than the narrow stile electrified MD8673.
22) Do the alternatives to the Sargent MD8673 meet the same ANSI grade for an institutional specification?
The MD8673 is a Grade 1 device. Grade 1 also holds for the Adams Rite 3300 and 8300 and 8400 Series, the Corbin Russwin ED5600AL, the Detex 30 Series Advantex, the Falcon 25-M-EO, the Von Duprin 5575-3ft, 8875-3FT, 9475/9575 Impact Series and 9875-3FT. For a spec written to Grade 1 mortise exit devices, the deciding factors are stile type, door material, fire rating and whether the opening needs the electrified function, not the grade line itself.
23) Will an Adams Rite 8400 fit the same door thickness as a Sargent MD8673?
Not necessarily, and it is worth confirming before the order. The MD8673 is built for hollow metal doors 1-3/4 inch to 2-1/4 inch thick. Among the alternatives, the Corbin Russwin ED5600AL, the Falcon 25-M-EO, the Von Duprin 5575-3ft, the Von Duprin 8875-3FT and the Von Duprin 9875-3FT are each specified at 1-3/4 inch. On a leaf thicker than 1-3/4 inch, the MD8673 range covers it where those five are at the single thickness.
24) I want the exit devices across my building to match. What finishes does the Sargent MD8673 come in?
Twelve finishes: 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, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, BSP black suede powder coat and WSP white suede powder coat. 32D is the usual choice on hollow metal openings in commercial and institutional work.
25) My opening takes abuse. Is there a mortise exit device built for impact?
The MD8673 is a Grade 1 device with a stainless steel top bolt, but if the concern is carts and equipment hitting the push rail, the Von Duprin 9475/9575 Impact Series uses a recessed push pad for wide stile doors and is Grade 1. It is not fire rated, so it does not go on a fire opening.
