Marks USA M9900EA-32D – Frequently Asked Questions

1) What door thickness does the Marks M9900EA rim exit device fit?
1-3/4 inches, and only that. It is a single-thickness device, which covers the standard commercial door but not a thicker aluminum or storefront leaf. If you are working a 2 inch or 2-1/4 inch door, a device with a stated range fits better: the DORMA 9300 Series covers 1-3/4 to 2-1/4 inches, the SDC S6136 covers 1-3/4 to 2 inches, and the Adams Rite 8800 Series covers 1-3/4 to 2-1/4 inches.
2) Does the Marks M9900EA alarm need to be hardwired, or does it run on a battery?
It runs on a standard 9V battery. Nothing to hardwire and no power supply or transformer to order, which is why it goes onto an existing back door or stair discharge without pulling wire. Maintenance is just a battery change. There is also a remote status output built in if you later want the door reported back to a monitoring or access control panel.
3) Will the Marks M9900EA drop into the door prep from the exit device I'm replacing?
Marks builds the M9900EA to retrofit all popular door preparations, which is the point of it on a school or campus job where you are swapping alarmed exits one at a time rather than replacing doors. The constraint to check is thickness, not prep: the device is for 1-3/4 inch doors only. If the old device was on a fire door, the M9900EA is not a substitute, since it carries no fire rating.
4) Does the Marks M9900EA come with outside trim, or do I order a lever separately?
Trim is a separate order. The M9900EA is an exit-only device, meaning it releases from the inside push side and there is no outside key or lever operation built into it. Marks exit device trim is sold separately, so if anyone needs to get back in through that door, add the trim to the order. If you want outside key access as part of the device family instead, a night latch rim device like the Sargent 8504 is the function to look at.
5) What is the closest equivalent to the Marks USA M9900EA if the door needs a fire label?
The M9900EA is not fire rated, so a fire-labeled opening needs a different device. Among fire-rated rim devices, 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 Orca Hardware OED85 Series is a 36 inch fire rated rim exit device in exit only function. None of those carry the M9900EA battery-powered alarm, so a fire-rated opening that also needs local alarm annunciation is handled by the device plus a separate alarm.
6) Which rim exit device replaces a Marks USA M9900EA on a narrow stile aluminum storefront door?
The M9900EA is a Grade 1 rim device for 1-3/4 inch doors and is not a narrow stile design. For a narrow stile aluminum door, Grade 1 narrow stile rim devices include the TownSteel ED3700 in 36 inch, the Falcon 19-R Series in 36 inch exit only for 1-3/4 inch doors, the Corbin Russwin ED4200 in 36 inch, and the Detex 40 Advantex Series in extra heavy duty. Adams Rite narrow stile rim devices such as the 8700 Series 30 inch also cover this opening and are rated for wood doors as well.
7) What is the plain rim exit device version of the Marks USA M9900EA without the alarm?
The M9900EA is an exit only rim device whose distinguishing feature is a 9V battery-powered 100 dB alarm with LED status. Where the alarm is not wanted, Grade 1 exit only rim devices with hex key dogging on the same door thickness include the Von Duprin 22-3FT, a 36 inch non-handed wide stile pushpad device for 1-3/4 inch doors, the TownSteel ED9700 36 inch heavy duty wide stile device, and the Corbin Russwin ED5200 36 inch wide stile device for 1-3/4 inch doors. The Design Hardware 1000R at 33 inches is a heavy duty rim device that also uses hex key dogging.
8) Can a Sargent 12-8810-LTRIM or a Detex 00 Series be used in place of a Marks M9900EA?
No, and the part names are the reason to check. The M9900EA is an exit only panic device that latches and releases the door. The Detex Advantex 00 Series is a super-heavy-duty dummy exit device in wide stile, and the Sargent 12-8810-LTRIM is a fire rated wide stile rim device in dummy function. Dummy devices provide the bar appearance and push action without a working latch, so they belong on an inactive leaf, not on the egress door the M9900EA secures.
9) What replaces a Marks M9900EA when the door needs outside key access rather than exit only?
The M9900EA is exit only and its trim is sold separately. Devices that state outside trim capability in their function include the Corbin Russwin ED5200, a Grade 1 36 inch wide stile device listed as exit only and accepts trim for 1-3/4 inch doors, and the Corbin Russwin ED4200, a Grade 1 36 inch narrow stile device with the same exit only and accepts trim function. The Sargent 8504 is a narrow design rim device supplied in night latch function, which retracts the latch by key from outside.
10) How loud is the Marks M9900EA exit alarm and how do you tell if it is armed?
100 dB when it trips. Status reads off the LED: armed shows a green LED blinking every 4 seconds, alarm mode shows red, and bypass shows no LED at all. That last one matters on a walk-through, because a dark LED means the door is bypassed and not being watched.
11) Can the Marks M9900EA be set so the alarm doesn't sound the second the door opens?
Yes, there's a selectable arming delay of either 5 or 60 seconds. The 60 second setting is what you use on a door that legitimately gets opened for deliveries or cart traffic, so staff have time to clear without the horn going off. Reset behavior is also selectable: continuous alarm until someone resets it by key, or automatic re-arm 2 minutes after the door closes, with a manual key reset available any time before that 2 minutes runs out.
12) Can I hold the Marks M9900EA touchbar open during business hours?
Yes, with hex key dogging. Insert the hex wrench and the touchbar stays retracted, so the door pushes free while the building is open and you re-dog it at close. If you want the same dogging arrangement without the alarm, the Design Hardware 1000R heavy duty rim device and 2000R standard duty rim device both come with hex key dogging.
13) Is the Marks M9900EA rated for heavy institutional traffic?
It meets ANSI 156.3 (2001) Grade 1 and is UL Listed for Panic Hardware, which is the top duty tier for exit hardware and what a school or hospital spec usually calls for. Build is a heavy-duty cast chassis with a reduced-projection touchbar, and the mitered steel end cap is flush so carts and equipment are less likely to break it off in a corridor.
14) Should I use an alarmed exit device like the Marks M9900EA or a plain rim device plus a separate alarm?
Go with the M9900EA when the door itself is the problem: a rear exit, a stair discharge, or a stockroom door people push through to skip the front. The alarm, the LED status, the delay and the reset are all in the device, so it is one piece of hardware and one 9V battery instead of a device plus a door alarm plus power. Choose a plain rim device when you only need free egress with no deterrent, or when the door is fire rated. Straight non-alarmed Grade 1 rim options include the Von Duprin 22 Series wide stile pushpad device for 1-3/4 inch doors, the Corbin Russwin ED5200 wide stile device, and the TownSteel ED1100 heavy duty wide stile device.
15) Can the Marks M9900EA report door status back to my access control system?
Yes. A remote status output is built into the device, so the alarm state can be tied into a building monitoring or access control panel rather than relying on someone hearing the 100 dB horn. If you need a device that actually releases electrically as part of the access control system, that is a different product class, and something like the SDC S6136 electrified rim exit device or the Securitron EMB electromechanical exit bar is the direction to go.
16) Is an SDC exit bar a substitute for the Marks USA M9900EA alarmed exit device?
They solve different problems. The M9900EA is a mechanical Grade 1 panic device with a self-contained 9V battery alarm that sounds at the door. The SDC MSB550 Series 36 inch is a mechanical switch bar that releases an electromagnetic lock, and the SDC SureExit PSB560 Series 36 inch is a pressure sense bar with tri-failsafe technology; both are switching devices that depend on an electrified locking system rather than a latching panic device. The SDC S6136 Spectra is an electrified architectural rim exit device with a 4 inch wide stile for 1-3/4 inch to 2 inch doors and does latch, but it requires power rather than a battery.
17) What is a Grade 2 alternative to the Marks USA M9900EA rim exit device?
The M9900EA meets ANSI 156.3 (2001) Grade 1. Where a Grade 2 chassis suits the opening, the Cal-Royal 5000 is a 36 inch wide rim exit device with a touch bar and a Grade 2 heavy duty chassis, and the Cal-Royal 5500 is a 48 inch wide rim device with a push bar, also Grade 2 heavy duty. Neither includes an onboard alarm.
18) What rim device covers a 48 inch wide door when the Marks M9900EA does not?
For wide openings, the Sargent 2828 and Sargent 3828 are Grade 1 reversible exit only wide stile rim devices for 48 inch minimum door width, 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, the Cal-Royal A9820 is a 48 inch exit only heavy duty rim device, and the CRL Jackson 1095 Series 48 inch is a crossbar rim panic device in wide stile exit only.
19) Which rim exit devices besides the Marks M9900EA use hex key dogging?
The M9900EA uses hex key dogging to hold the touchbar retracted for free egress during business hours. Other rim devices that specify hex key dogging include the Design Hardware 1000R 33 inch heavy duty device, the Design Hardware 2000R 33 inch standard duty wide stile device, and the Stanley Security QED200 Series Grade 1 heavy duty narrow stile device. Standardizing on one dogging method across a building keeps a single hex key working every opening.
20) What is the difference between the Marks M9900EA and an electrified rim exit device for controlling an emergency exit?
The M9900EA carries its own 9V battery alarm with a remote status output, so it annunciates at the door and can report to a monitoring system without being wired for power. The Dormakaba E2103 with 4908A trim is a 36 inch electrified rim device in 08-Classroom function, and the Securitron EMB is an electromechanical exit bar for 2-1/4 inch doors. Those depend on building power and an access control head end, where the M9900EA operates standalone on a battery.
21) What finish does the Marks M9900EA exit alarm device come in?
One finish: US32D satin stainless steel. That is the standard institutional finish, so it will sit consistently alongside stainless push plates, pulls and closers already on a school or office corridor. There is no other finish option on the M9900EA, so a building standardized on bronze or black will not get a match here.
22) Do I need to buy an exit alarm sign for the door separately?
No, an "Emergency Exit - Alarm Will Sound" door sign ships with the M9900EA. A bar sign, the one that mounts on the touchbar itself, is a separate optional accessory if you want the warning right at the point of contact.
