Sargent SGT-12-19-MD8415G – Frequently Asked Questions

1) What handing do I need to order for a Sargent MD8415 concealed vertical rod device?
Handing is a required choice, and it is not field reversible on your order form. The MD8415G is ordered either LHR (left hand reverse) or RHR (right hand reverse). Stand outside the opening: an exit device door swings out toward you, so the hinge side as seen from the push side determines reverse handing. Get it wrong and the lever trim and latching will not line up.
2) My classroom doors are 36 inches wide. Which rail size do I specify on the Sargent 8400 concealed vertical rod device?
For a 36 inch door you want the F rail. The rail options cover 24 to 48 inch door widths: E rail for 24 to 32 inches, F rail for 33 to 36 inches, J rail for 37 to 42 inches, and G rail for 43 to 48 inches. Rails are factory cut, so the width has to be settled at order time rather than trimmed on site. The G suffix on the 12-19-MD8415G is the 43 to 48 inch rail, matching the 48 inch device length.
3) Does a concealed vertical rod exit device need a mullion on a pair of doors?
No. A concealed vertical rod device latches at the head and at the threshold, through the 650 top strike and 606 bottom strike, so it secures a pair of doors without a center mullion. That is the main reason to choose a vertical rod over a rim device, which latches into a strike on the frame or mullion and needs something to catch at the center of a pair. The tradeoff is door prep: the rods run inside the door, so the door has to be prepped or ordered for concealed rod, where a rim device mounts on the face.
4) What does passage function mean on this Sargent exit device, and is it right for a classroom?
Passage means the outside lever is always unlocked, so the P lever trim retracts the latch at any time and the device is pure egress plus free entry. There is no keyed or locked state. If you need the ability to secure the classroom from entry, passage function is the wrong choice and you want a locking function instead. Use passage where the opening needs a lever pull and panic egress but no outside control, such as a corridor or stairwell exit that stays open during occupied hours.
5) Is the Sargent 12-19-MD8415G fire rated, and what grade is it?
It is a fire-rated device and carries a Grade 1 rating. The 650 top strike and 606 bottom strike are the components called out for panic and fire-rated applications. Note that fire-rated vertical rod devices cannot be dogged, so do not plan on holding this latch retracted mechanically for daytime traffic.
6) How high is the Sargent MD8415 exit device mounted, and can it go lower for an elementary school?
Standard mounting is a 41 inch centerline from finished floor. For elementary schools and accessibility reach, it mounts at 38 inches when used with the 100 Series Auxiliary Control. Confirm which height the drawings call for before the door is prepped, since concealed rod prep is not something you move afterward.
7) How far does this Sargent exit device project off the door face?
Projection is 3 inches at neutral and 2-1/8 inches when the touchpad is depressed. That matters where the door swings into a tight vestibule, a corridor clear width, or against a wall or adjacent leaf. The center case measures 8-3/8 x 2-5/8 inches.
8) Can I add alarm or monitoring options to the Sargent 8400 concealed vertical rod device?
Yes, several electrical options are available: AL alarm, BT beacon, PL SARGuide photoluminescent, TL SARGuide illuminated touchpad, and monitoring options 53 through 59. These are order-time suffixes, not field add-ons, so specify them with the device. Anything powered also means you need to plan a power transfer at the hinge or frame as part of the opening.
9) Is this device narrow stile, and will it work on an aluminum storefront door?
It is classed as narrow stile and needs a 4-1/2 inch minimum stile, but it is specified for hollow metal doors, not aluminum storefront. For a glass front or aluminum entrance you want a device built for that application. Door thickness also has to land between 1-3/4 and 2-1/4 inches.
10) What door height does the 48 inch Sargent MD8415G cover?
The ordered configuration is set up for 96 inch doors with a 48 inch device, which is the standard commercial opening height. Concealed vertical rods are cut to the door height, so a taller leaf is a different rod length and has to be specified that way. The device cannot exceed a 120 inch door opening height.
11) What finishes does the Sargent MD8415G concealed vertical rod device come in?
Two finishes: 32D satin stainless steel and 10B dark oxidized satin bronze, oil rubbed. Both are offered in LHR and RHR handing at the 48 inch device size for 96 inch doors. 32D is the usual match for institutional and school openings; 10B suits darker bronze hardware schedules.
12) What trim comes with the Sargent 12-19-MD8415G, and do I order the lever separately?
The trim design is the P lever, which is the pull-side lever that retracts the latch. Since the function is passage, that lever operates freely with no cylinder involved, so there is no keyway or cylinder to specify on this configuration.
