Adams Rite 8522-42 – Frequently Asked Questions

1) Will the Adams Rite 8500 concealed vertical rod exit device fit a 2-inch thick door?
Yes. The 8500 Series covers door thicknesses from 1-3/4 inches through 2-1/4 inches, so a 2 inch door is inside the range. You also need at least a 3-1/2 inch stile to take the device, and the stile wall needs to be 1/8 inch thick where the mounting hardware lands. Most competing concealed vertical rod devices in this class are built for 1-3/4 inch doors only, so if you are working a thicker leaf the 8500 is one of the few that covers it outright.
2) Can I use the Adams Rite 8500 on a fire rated door opening?
No. The 8500 Series is not fire rated, so it cannot go on a labeled fire door assembly. For a fire rated concealed vertical rod device, the Sargent MD8613F is rated and carries the F suffix for fire door use. Note that a fire rated concealed vertical rod device also cannot be dogged, so if you were counting on the cylinder dogging option to hold the door in push-pull during the day, that is a reason the 8500 may still be the right pick on a non-labeled opening.
3) What do I have to specify when ordering an Adams Rite 8500 exit device?
Four things beyond finish. Size, in 30, 36, 42, or 48 inches to match the door width. Cylinder dogging, yes or no. Less bottom rod, yes or no. And the electrified option: none, alarm, LR electric latch retraction, or MLR motorized latch retraction. There is also a monitoring switch choice of none, single, or dual. Finishes run 313 dark bronze anodized, 335 black anodized, 605 bright brass, 606 satin brass, 628 clear anodized, 629 bright stainless, and 630 satin stainless. Handing is field reversible, so you do not specify it.
4) Can the Adams Rite 8500 be released remotely from an access control system?
Yes, two ways. LR electric latch retraction or MLR motorized latch retraction pulls the latches back at the device itself, which is what you want when the opening needs to go push-pull on a schedule or unlock on a card read while staying a code-compliant panic device. The other route is the 7800 Series electric strike, which the 8500 is compatible with. Single or dual monitoring switches are available if the head end needs to know the device position, and an alarm option is available on the same axis as the electrified choices.
5) What is the Adams Rite 8500 equivalent from Von Duprin, Corbin Russwin, or DORMA?
The closest match on stile type and thickness range is the DORMA 9100 Series, a Grade 1 wide stile pushpad concealed vertical rod rated for 1-3/4 to 2-1/4 inch doors, same range as the 8500. From Corbin Russwin the wide stile equivalent is the ED5800, Grade 1, but built for 1-3/4 inch doors. BEST Precision 2801 is another wide stile concealed vertical rod. Von Duprin's concealed vertical rod line in the comparable set, the 3347A, 5547, and 7547, is all narrow stile, so those are alternatives only if your door has a narrow stile rather than the 3-3/4 inch stile the 8500 wants.
6) What cylinder do I need for keyed entry on an Adams Rite 8500?
Keyed function on the 8500 takes a mortise cylinder with an MS cam. That is the Adams Rite cam, not a standard straight cam, so a stock mortise cylinder off the van will turn but will not drive the device. If you are ordering the cylinder dogging option, that also runs off a cylinder. Multiple trim options and levers are available if the outside needs an operating handle rather than key-only.
7) Is the Adams Rite 8500 Grade 1, and what does that mean for a school or hospital corridor?
Grade 1 under ANSI/BHMA is the highest durability tier for exit devices and is the level normally specified for institutional and heavy commercial traffic. The 8500 is Grade 1 and rated commercial, with single-motion panic proof egress, meaning one push on the bar releases both the top and bottom latches regardless of what else is locked. For a school or hospital corridor that is the behavior the life-safety code is after. One caution: the 8500 is not fire rated, so it does not go on labeled cross-corridor fire doors.
8) Should I use a concealed vertical rod device or a rim device with a mullion on a pair of doors?
A concealed vertical rod device like the 8500 latches at the header and the threshold on each leaf, so a pair of doors gets two-point locking with no center mullion in the way. That is the reason to pick it: a clear opening for carts, gurneys, and freight. The tradeoff is prep and maintenance. The rods run inside the door, so the leaf has to be prepped for them and adjustment means opening the door up. A rim device with a removable mullion is cheaper to prep and easier to service, but you lose the clear opening and somebody has to pull the mullion every time something wide comes through.
9) Should I order the Adams Rite 8500 less bottom rod?
Order less bottom rod when the bottom rod and floor strike are going to be a problem. That is doors over dirty or wet floors, high traffic openings where the bottom strike gets kicked and packed with debris, and anywhere the threshold makes a floor strike impractical. Dropping the bottom rod removes the most abused part of the assembly and cuts service calls. Keep the bottom rod when you need genuine two-point locking for security, because with less bottom rod the leaf is held only at the header. Less bottom rod is a yes/no option on the 8500 at order time.
10) How much does the Adams Rite 8500 push bar stick out from the door?
The touchbar projects 2-15/16 inches when fully projected and drops back to 1-15/16 inches when dogged. That one inch matters in a tight vestibule or where the door swings past a wall return or an adjacent leaf, so measure your clearance against the 2-15/16 inch figure, not the dogged one.
11) Is the Adams Rite 8500 handed, or do I need to know the door swing before ordering?
Handing is not a factor. The 8500 is field reversible, so one device covers left and right hand openings and a stocking contractor can carry a single part number for both leaves of a pair. Nothing to specify and nothing to return if the swing on the drawing turns out backwards.
12) I need a pushpad exit device, not a crossbar. Which concealed vertical rod devices are pushpad?
The 8500 uses a stainless steel touchbar. If you specifically want a pushpad style, the DORMA 9100 wide stile and the DORMA 9600BB narrow stile are both pushpad concealed vertical rod devices, and the CRL Jackson 1285 is a push pad device that fits narrow, medium, or wide stiles. Going the other way, if a crossbar is what matches the rest of the building, the Corbin Russwin ED7800 and Von Duprin 5547 are crossbar concealed vertical rod devices in narrow stile.
13) What fasteners come with the Adams Rite 8500, and do I need sex bolts?
The device mounts with standard self-tapping screws and machine screws. For higher security openings, where somebody could otherwise attack the device fasteners from the pull side, Sex Bolt Kit 26-0584 is available as an option and through-bolts the device instead. On a typical interior commercial opening the standard machine screws are fine; on an exterior or high-risk door, spec the sex bolts.
14) Which size Adams Rite 8500 do I order for a 36 inch door?
Order the 36 inch device. The 8500 comes in 30, 36, 42, and 48 inch lengths, sized to the door opening rather than trimmed on site, so match the bar length to the leaf width. A pair of 36 inch leaves takes two 36 inch devices, one per leaf, since each leaf latches independently at head and threshold.
15) What finish on the Adams Rite 8500 will match the aluminum storefront doors already in my building?
For a clear anodized aluminum storefront, 628 clear anodized matches. Dark bronze storefront takes 313 dark bronze anodized, and black takes 335 black anodized. The remaining choices are 605 bright brass, 606 satin brass, 629 bright stainless steel, and 630 satin stainless steel. The device body is aluminum with a stainless steel touchbar, which is why both anodized and plated finishes are on the list.
