Marks USA M9900KDE-32D – Frequently Asked Questions

1) How does the delay actually work on the Marks M9900KDE when someone pushes the bar?
Push the touchbar and the device holds for a selectable 15 or 30 second exit delay, preceded by a 1 or 2 second nuisance delay so a bump or a lean on the bar doesn't trigger a release. During the countdown an audible alarm sounds and a visual display shows the countdown, locked/unlocked status, and confirmation that egress has executed. Voice release messaging can carry the time remaining, a warning, or a safety message. The keyswitch and PIN codes handle Reset, Sustained Bypass, and Momentary Bypass.
2) Is the Marks M9900KDE exit only, or can I put lever trim on the outside for re-entry?
Exit only. The M9900KDE has no outside trim function, so staff coming back in need a separate means of access on that opening. If you need outside lever access through the device itself, a rim device that accepts trim is the better pick, such as the Corbin Russwin ED5200 (wide stile) or ED4200 (narrow stile), both Grade 1 and listed as exit only with trim capability.
3) Will the Marks M9900KDE go into the door prep from the old exit device I'm removing?
It's built to retrofit all popular door preps, which is why it gets specified on school and university replacement work where the leaves are staying and only the hardware is changing. It's a rim device, so it latches to a strike on the frame stop rather than into the head and threshold. Confirm the existing opening is 1-3/4 inch thick, since that is the only thickness this device is built for.
4) Is the Marks USA M9900KDE Grade 1 and UL listed for panic hardware?
Yes on both counts. The M9900KDE is certified to ANSI 156.3 (2001) Grade 1 and is UL Listed for Panic Hardware, which is what a spec on an institutional egress opening normally calls for. Note it is a panic listing, not a fire exit hardware listing, and the device carries no fire rating.
5) Is the Marks USA M9900KDE Delayed Egress Rim Exit Device approved for a fire-rated door opening?
No. The Marks USA M9900KDE carries no fire rating, so it should not be specified on a labeled opening. For fire-rated rim applications, Grade 1 fire-rated alternatives include the Dexter ED1000 Series Fire Rated Rim Exit Device and the Adams Rite 3700 Series 30 inch fire-rated narrow stile rim device. The Arrow FS1250 is a fire-rated 32 inch rim device for 1-3/4 inch doors, and the Orca Hardware OED85 Series 36 inch is a fire-rated exit-only rim device. Note that none of these substitutes provide the delayed egress timing, PIN code control, or countdown display the M9900KDE is built around, so a fire-rated opening that also needs delayed egress requires a different engineering approach.
6) What is a simpler mechanical alternative to the Marks USA M9900KDE if the opening does not need delayed egress?
If the door only needs free mechanical egress, a standard Grade 1 rim device covers it without the delay electronics. The Von Duprin 22-3FT is a 36 inch non-handed wide stile pushpad rim device rated Grade 1 for 1-3/4 inch doors, the same door thickness the Marks USA M9900KDE is built for. Corbin Russwin ED2200 is a 36 inch Grade 1 exit-only wide stile rim device, and TownSteel ED9700 is a 36 inch Grade 1 heavy duty wide stile rim device. These are mechanical exit-only bars with no exit delay, nuisance delay, audible alarm, or status display, so any controlled-egress requirement in the facility drives you back to the M9900KDE.
7) What should I use instead of the Marks USA M9900KDE on a door thicker than 1-3/4 inches?
The Marks USA M9900KDE is designed for 1-3/4 inch door thickness, so a thicker leaf needs a different device. The DORMA 9300 Series 48 inch wide stile rim device is rated for 1-3/4 inch to 2-1/4 inch doors, and the Adams Rite 8800 Series 30 inch narrow stile device covers the same 1-3/4 inch to 2-1/4 inch range. The SDC S6136 Spectra electrified rim device handles 1-3/4 inch to 2 inch with a 4 inch wide stile, and the Securitron EMB electromechanical exit bar is listed at 2-1/4 inch. The SDC and Securitron options are the closest in spirit if the opening also needs electronic control.
8) How does the Marks USA M9900KDE compare with an SDC switch bar or pressure sense bar for controlled egress?
They solve controlled egress from opposite ends. The Marks USA M9900KDE is a Grade 1 rim exit device, UL Listed for panic hardware, with the egress control built into the device itself - selectable 15 or 30 second delay, 1 or 2 second nuisance delay, PIN code control, audible alarm, and a countdown display. The SDC MSB550 Series 36 inch mechanical switch bar and the SDC SureExit PSB560 Series 36 inch pressure sense bar are switching bars that release a separate lock, fitting narrow or wide stile doors, with the PSB560 using tri-failsafe technology. The SDC bars require an electromagnetic lock or strike to actually secure the door; the M9900KDE latches the opening itself.
9) Is a Cal-Royal 5000 or A9800 rim device a direct substitute for the Marks USA M9900KDE in a school?
Not a like-for-like swap. The Marks USA M9900KDE is rated to ANSI 156.3 (2001) Grade 1 and UL Listed for panic hardware, and its application is schools, universities and other institutional or commercial buildings. The Cal-Royal 5000 36 inch touch bar rim device and the Cal-Royal A9800 Series 36 inch exit-only rim device are both listed as Grade 2 heavy duty, and the Cal-Royal 5500 48 inch push bar device is also Grade 2. If the specification on the drawing calls for Grade 1 panic hardware, the Cal-Royal devices will not satisfy it, and none of them include the delayed egress package.
10) We only need an alarmed exit bar, not a full delayed egress device. Is the M9900KDE overkill?
Probably, yes. The M9900KDE is a delayed egress device with timed hold, PIN control, voice release, and a countdown display, and it carries all the electronics that go with that. If all you need is a plain Grade 1 rim panic on a 1-3/4 inch door, the Von Duprin 22 Series, the TownSteel ED1100, or the Corbin Russwin ED2200 are straight mechanical wide stile rim devices. If you want the door held by a maglock and released by the bar rather than a delay built into the device, the SDC MSB550 mechanical switch bar or SDC PSB560 pressure sense bar are a different route to the same control.
11) Will the touchbar on the Marks M9900KDE survive a corridor where carts hit the doors?
That is the case it's built for. The M9900KDE uses a cast chassis with a mitered steel flush-mounted Panic Protector End Cap, which is the part that normally gets torn off by carts and gurneys, and the touchbar is a reduced-projection design that cuts down on things catching on it in a busy corridor. It's specified for schools, universities, and similar high-abuse institutional traffic.
12) Can the Marks M9900KDE secure a pair of doors?
Not by itself. A rim device latches into a strike on the frame, so a pair of doors needs a center mullion for the strike to mount on, or a different device type. For a pair with no mullion, a vertical rod device that latches at the head and sill is the right answer, such as the Hager 4501 concealed vertical rod (wide stile pushpad) or the Hager 4601 narrow stile version.
13) Who can reset the Marks M9900KDE after an alarm, and how is that controlled?
Reset is handled through the integrated keyswitch and through user PIN codes. Codes can be assigned to one, two, or all of the control functions, meaning Reset, Sustained Bypass, and Momentary Bypass. That lets a facility give a front-desk staffer momentary bypass only while security keeps reset and sustained bypass, without issuing everyone a key.
14) Can the Marks USA M9900KDE go on a narrow stile aluminum storefront door?
The Marks USA M9900KDE is a rim device built on the heavy-duty M9900 cast chassis for 1-3/4 inch doors and is not described as a narrow stile device. For aluminum storefront stiles, purpose-built narrow stile rim devices include the Adams Rite 8700 Series 30 inch and the Adams Rite 8800 Series 30 inch, the latter covering 1-3/4 inch to 2-1/4 inch door thickness. Falcon 19-R is a Grade 1 narrow stile exit-only rim device for 1-3/4 inch doors, and TownSteel ED3700 is a 36 inch Grade 1 narrow stile rim device. A glass front installer working tight stiles should measure the stile face before committing to a wide-chassis device.
15) If I need a 48 inch wide opening instead of what the Marks USA M9900KDE covers, what rim devices are available?
For 48 inch leaves, the Sargent 2828 and Sargent 3828 are Grade 1 reversible wide stile rim exit devices for 48 inch minimum door width, both exit only, with the 3828 using a standard push bar. The Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device for 1-3/4 inch doors, and the DORMA 9300A is a 48 inch Grade 1 wide stile device. The CRL Jackson 1095 Series 48 inch crossbar rim panic device is another exit-only option. All of these are straight mechanical panic devices without the delayed egress timing and display of the Marks USA M9900KDE.
16) What looks like a substitute for the Marks USA M9900KDE but is not a functioning exit device?
Two items in the rim exit family will not latch or release a door. The Detex Advantex 00 Series is a super-heavy-duty dummy exit device with wide stile design, and the Sargent 12-8810-LTRIM is a fire-rated wide stile rim device in a dummy function. Both are for the inactive leaf or for matching appearance, and neither provides egress. The Marks USA M9900KDE is an exit-only device with active delayed egress control, so a dummy bar is never a functional replacement for it.
17) What finish does the Marks M9900KDE delayed egress device come in?
One finish: US32D satin stainless steel. That's the standard institutional finish, so it will sit alongside existing stainless push bars, pulls, and hinges on a school or hospital corridor without looking odd.
