Marks USA M9900VRKDE-32D – Frequently Asked Questions

1) How does the delay work on the Marks M9900VRKDE, and can I change the timing?
Egress delay is configurable at 15 or 30 seconds, with a nuisance delay of 1 or 2 seconds so a casual push does not start the cycle. When someone pushes and holds the touchbar, an audible alarm sounds along with a voice release, time, warning or safety message, and the visual display counts down and shows locked, unlocked, or egress-executed status.
2) Will the Marks M9900VRKDE latch a pair of doors without a mullion?
It is a vertical rod device, so it latches at the head and the sill rather than into a strike on the frame edge. That is what lets it secure the active leaf of a pair without a center mullion. A straight rim device like the Von Duprin 22 or the TownSteel ED1100 latches into the frame or an adjacent leaf and needs a mullion on a pair.
3) Can I use the Marks M9900VRKDE for a classroom or storeroom function with outside lever trim?
No. The M9900VRKDE is exit only, meaning there is no outside trim function on it. If you need entry from the corridor side, look at a device catalogued to accept trim, such as the Corbin Russwin ED5200 or ED4200, both Grade 1 and listed as exit only plus accepts trim, or the Dormakaba E2103 electrified rim device with 4908A classroom trim.
4) What is the closest alternative to the Marks USA M9900VRKDE if the opening needs a fire-rated exit device?
The Marks USA M9900VRKDE is not fire rated, so it cannot go on a labeled opening. For a fire-rated exit, the Dexter ED1000 Series ED1000-R-F-EO is a Grade 1 fire rated rim exit device, the Arrow FS1250 is a fire rated 32 inch rim exit device, and the Adams Rite 3700 Series 30 inch is a Grade 1 fire-rated narrow stile rim device. Note that none of those carry the delayed egress electronics the M9900VRKDE has, so if the opening needs both a label and delayed egress you would be pairing a fire-rated device with separate access control.
5) If I do not need delayed egress, what plain mechanical Grade 1 exit-only device can I use instead of the Marks USA M9900VRKDE?
The M9900VRKDE's value is its 15 or 30 second delayed egress with keyswitch, PIN bypass and countdown display. For a straight mechanical exit-only opening, Grade 1 alternatives include the Von Duprin 22-3FT, a 36 inch non-handed wide stile pushpad rim device for 1-3/4 inch doors; the Corbin Russwin ED2200-WO36, a 36 inch Grade 1 wide stile exit-only rim device; and the TownSteel ED1100-36, a 36 inch heavy duty Grade 1 wide stile panic rim device. All three are mechanical only with no egress delay electronics.
6) What other electrified exit bars compare with the Marks USA M9900VRKDE for access-controlled egress?
The M9900VRKDE handles delay internally with a keyswitch, PIN-code bypass modes, audible alarm with voice release and a visual countdown. Comparable electrified bars include the SDC MSB550 Series 36 inch mechanical switch bar with electromagnetic lock release, the SDC SureExit PSB560 Series 36 inch pressure sense bar with tri-failsafe technology, the Securitron EMB electromechanical exit bar, and the Dormakaba E2103 electrified 36 inch rim device with 4908A trim. The SDC and Securitron bars are switch or sense bars that release a separate locking device, while the Marks unit is a latching vertical rod device with the delay logic on board.
7) I need a vertical rod device rather than a rim device - what else is available besides the Marks USA M9900VRKDE?
The M9900VRKDE is a vertical rod device, latching top and bottom rather than into a strike on the frame. Other vertical rod options are the Hager 4501 Series 36 inch Grade 1 concealed vertical rod device with wide stile pushpad and the Hager 4601 Series 36 inch Grade 1 concealed vertical rod narrow stile device. Both Hager units are concealed rod and mechanical only, where the Marks device adds the delayed egress keyswitch and countdown control.
8) Who can bypass or reset the Marks M9900VRKDE without waiting out the delay?
Two paths: the integral keyswitch, and PIN codes. PIN codes can be assigned to one, two, or all of the control functions, which include Reset, Sustained Bypass, and Momentary Bypass. That lets you give front-desk staff a momentary release while keeping reset authority with facilities or security.
9) Am I going to have to re-prep the door to put a Marks M9900VRKDE on it?
Marks built the M9900 series to retrofit all popular door preps, so on a 1-3/4 inch door already carrying an exit device you are generally working with the existing holes. The device chassis is cast heavy duty and the touchbar is reduced projection with a mitered steel flush-mounted Panic Protector end cap, which is the part that takes the beating from carts in a school corridor.
10) What is a good alternative if I need delayed egress or electrified release but the Marks M9900VRKDE will not suit the door?
Two different directions. For an electrified release paired with a mag lock, the SDC MSB550 Series 36 inch mechanical switch bar or the SDC SureExit PSB560 pressure sense bar with tri-failsafe both mount on narrow or wide stile doors. For a self-contained electromechanical bar, the Securitron EMB is listed for 2-1/4 inch doors. If you only need a standard latching exit device and the delayed egress is not required, the Corbin Russwin ED2200 or TownSteel ED9700 are Grade 1 wide stile rim devices.
11) My door is an aluminum narrow stile storefront - is the Marks USA M9900VRKDE the right choice?
The M9900VRKDE is a wide-style touchbar device built on a heavy cast chassis for 1-3/4 inch doors, not a narrow stile storefront device. For narrow stile aluminum openings, look at the Adams Rite 8800 Series 30 inch rim device, rated Grade 1 for 1-3/4 inch to 2-1/4 inch doors; the Falcon 19-R Series 36 inch Grade 1 narrow stile exit-only device for 1-3/4 inch doors; or the TownSteel ED3700-36, a 36 inch Grade 1 heavy duty narrow stile rim device.
12) Is a Cal-Royal 5000 or A9800 a direct swap for the Marks USA M9900VRKDE?
No. The Marks USA M9900VRKDE is certified to ANSI 156.3 (2001) Grade 1 and UL Listed for panic hardware, with onboard delayed egress. The Cal-Royal 5000 is a 36 inch heavy duty touch bar rim device carrying a Grade 2 chassis, and the Cal-Royal A9800 Series 36 inch exit-only rim device is likewise listed Grade 2. Both are mechanical rim devices with no egress delay, so they are a different class of device rather than a substitute.
13) For a 48 inch wide opening, what Grade 1 device works where the Marks USA M9900VRKDE does not fit?
For wider leaves, Grade 1 options include the Sargent 2828 reversible rim exit device for 48 inch minimum door width, the Sargent 3828 standard push bar rim device for 48 inch doors, the Corbin Russwin ED3200 48 inch crossbar rim device for 1-3/4 inch doors, and the DORMA 9300 Series 48 inch wide stile exit-only device for 1-3/4 inch to 2-1/4 inch doors. All are mechanical devices without the Marks unit's delayed egress control.
14) What device should I use instead of the Marks USA M9900VRKDE if I need outside trim for re-entry?
The M9900VRKDE is an exit-only function. If the opening needs keyed or lever re-entry from the outside, the Corbin Russwin ED5200 is a 36 inch Grade 1 wide stile rim device listed as exit only, accepts trim, and the Corbin Russwin ED4200 is a 36 inch Grade 1 narrow stile device also listed as accepting trim; both are for 1-3/4 inch doors. The Sargent 8504 is a narrow design rim device in night latch function for key retraction from outside.
15) For a high-abuse school corridor, what compares with the Marks USA M9900VRKDE end cap and chassis?
The M9900VRKDE uses a heavy duty cast chassis with a mitered steel flush-mounted Panic Protector End Cap to resist cart impacts, and is applied to schools, universities and other institutional or commercial buildings. On comparable abuse ratings, the Detex 10 Advantex Series 36 inch is a wide stile Grade 1 device rated extra heavy duty, and the Detex 40 Advantex is a narrow stile Grade 1 device also rated extra heavy duty. Those Detex devices are mechanical rim devices, so they do not provide the Marks unit's timed egress delay and alarm.
16) What finish does the Marks M9900VRKDE delayed egress device come in?
One finish: US32D satin stainless steel. That matches the most common commercial hardware finish in schools and institutional corridors, so it will sit alongside existing 32D push plates, pulls, and closer covers without looking off.
17) Is the Marks M9900VRKDE suitable for a residential or light-duty opening?
It is a commercial device, certified ANSI 156.3 (2001) Grade 1 and UL Listed for panic hardware, and intended for schools, universities, and other institutional or commercial buildings. Grade 1 is the highest ANSI/BHMA duty level, so it is more device than a light-traffic residential or small-office door needs.
18) Can I use the Marks USA M9900VRKDE on a wood door?
The M9900VRKDE is specified for 1-3/4 inch door thickness and retrofits popular preps, but the comparable devices confirmed for wood doors are the Adams Rite narrow stile rim devices - the 8700 Series 30 inch and the fire-rated 3700 Series 30 inch are both listed as wood door compatible and Grade 1. Most other Grade 1 rim devices in the class, including the Von Duprin 22 Series and the TownSteel ED1100, are listed as not wood door compatible.
19) Is the Detex 00 Series a substitute for the Marks USA M9900VRKDE?
No. The Detex Advantex 00 Series is a super-heavy-duty dummy exit device with wide stile design, meaning it has no latching or panic function - it is used for matching appearance on an inactive leaf. The Marks USA M9900VRKDE is a functioning exit-only vertical rod device that is UL Listed for panic hardware. Similarly, the Sargent 12-8810-LTRIM is listed in dummy function, so it is not a working panic substitute either.
