Marks USA 195FEU/26D – Frequently Asked Questions

1) Will the Marks USA 195FEU electric lever fit a 1-3/4 inch commercial door?

Yes. The 195FEU covers door thicknesses of 1-5/8 inch to 1-7/8 inch, so a standard 1-3/4 inch commercial door falls in the middle of the range. For a 1-3/8 inch door (common on older interior openings) you need the K1704 spacer, which is not part of the standard lock.

2) Does the Marks 195FEU lock or unlock when the power drops?

It locks. The 195FEU is a fail-secure electric unlock function, so cutting power leaves the outside lever locked and you need the key to get in. If your egress or life-safety plan requires the door to release on power loss, this is the wrong device. Note the electrical side draws power to unlock at 100 percent duty cycle: 24V/AC through a bridge rectifier, or 24V/DC at 0.21 Amps standard, with 12V/DC optional.

3) Should I order the 12VDC or the 24VDC version of the Marks 195FEU?

Match it to your power supply and access control panel. Both voltages are orderable, in either finish: US26 polished chrome or US10B oil-rubbed dark bronze. 24V/DC at 0.21 Amps is the standard build and is what you want if you are running long cable homeruns from a central supply, since the current draw is lower for a given wire gauge. 12V/DC is the optional build for panels already sitting on a 12 volt bus.

4) Will the Marks 195FEU latch into the strike I already have in the frame?

It depends on what is prepped. The 195FEU ships with a 2-3/4 inch backset, a #1834 latch with a 1-1/8 x 2-1/4 inch front and a 9/16 inch deadlocking throw, and a #1135 strike with a 4-7/8 inch ASA curved lip. If your frame is already cut for a 4-7/8 inch ASA strike and the existing latch face is 1-1/8 x 2-1/4 inches, it drops straight in. A frame prepped only for a T-strike or a 2-3/4 inch ANSI strike needs new frame work. Backsets of 2-3/8, 3-3/4 and 5 inches are optional if the bore in the door is not at 2-3/4.

5) Can the Marks USA 195FEU go on a fire rated door?

Yes. The 195FEU is UL Listed with a 3-hour fire rating, and the latch is deadlocking, which is what a rated opening needs so the bolt cannot be shimmed back once the door is closed. It also carries ANSI/BHMA Grade 1 and the lever meets ADA.

6) Do I need a separate request-to-exit switch with the Marks 195FEU electrified lever?

Plan on ordering it. The REX switch is not standard on the electrified leverset. When specified, it is a single pole double throw switch rated 3 amps at 125 VAC and can be wired normally open or normally closed to suit your panel input. Without it your access control system gets no signal that someone left through the door from the inside.

7) What is the difference between a hardwired electric lockset like the Marks 195FEU and a standalone battery keypad lock?

The 195FEU is a wired device: it runs on 24V/AC through a bridge rectifier or 24V/DC at 0.21 Amps (12V/DC optional) from your access control panel, so the credential decision, the audit trail and the scheduling all live in the panel, and there are no batteries to change. A standalone lock puts all of that in the door. If you have no cabling to the opening, look at the Alarm Lock Trilogy T2 DL2700, which is a Grade 1 standalone electronic cylindrical lock with a digital keypad, 100 user codes and IC/SFIC compatibility, or the Alarm Lock T3 DL3075 if you need an audit trail at the door. Both are Grade 1 like the 195FEU, and the DL2700 covers the same 1-5/8 inch to 1-7/8 inch door range.

8) What is the closest wired solenoid alternative to the Marks 195FEU if my doors are thicker than 1-7/8 inch?

The 195FEU stops at 1-7/8 inch. For a 2 inch door, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock with dual voltage 12/24VDC covering 1-3/4 inch to 2 inch doors, which is the same kind of panel-powered electric lock in a thicker door range. Below the 195FEU range, at 1-3/8 inch, you can bring the Marks lock into spec with the K1704 spacer instead of changing product.

9) What is the closest equivalent to the Marks USA 195FEU if I need a hardwired electric cylindrical lock rather than a battery keypad?

The SDC Electra 7200 Series solenoid controlled cylindrical lock is the nearest hardwired peer to the Marks USA 195FEU. Both are electrically controlled cylindrical locksets driven from a power supply rather than batteries, and the SDC 7200 runs dual voltage 12/24VDC, which lines up with the 195FEU voltage choices of 12VDC and 24VDC. The difference to check at the opening is door thickness: the SDC 7200 Series covers 1-3/4 inch to 2 inch doors, while the 195FEU is built for 1-5/8 inch to 1-7/8 inch. On a 1-5/8 inch door the Marks fits and the SDC does not; on a 2 inch door the reverse is true.

10) We have no wiring to the door. What should we use instead of the Marks USA 195FEU?

An access controlled opening with no cabling to the leaf needs a standalone lock with its own power at the door. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a digital keypad, 100 user codes, and IC/SFIC compatibility, and it is built for 1-5/8 inch to 1-7/8 inch doors, the same thickness window the Marks USA 195FEU covers, so the door prep assumption carries over. The Alarm Lock DL5200 is the double-sided version with 100 user capacity and battery operation across the same 1-5/8 inch to 1-7/8 inch range when both faces need code entry. The tradeoff is control: the 195FEU is unlocked by a signal from the access control system, while the Trilogy locks are credentialed at the keypad.

11) Is the Schlage NDEB a substitute for the Marks USA 195FEU on a networked access control door?

They solve the same problem by different paths. The Schlage NDEB is a Grade 1 heavy duty ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader, mobile enabled and multi-function, covering 1-5/8 inch to 2 inch doors. It carries the credential reader on the lock itself. The Marks USA 195FEU is a Grade 1 cylindrical lever lockset that takes an unlock signal from a separate reader and controller at 24V/AC with bridge rectifier, 24V/DC at 0.21 Amps, or 12V/DC. If the reader, controller, and power supply are already specified for the opening, the 195FEU drops into that architecture; if the intent is to put the credential handling in the lock and skip the head end, the NDEB is the one that matches.

12) How does the Marks 195FEU hold up on an abused door like a school corridor or a dorm?

That is what the Survivor Series construction is aimed at. The lock takes 1,800 inch-pounds of torque, over twice the ANSI/BHMA (1996) test value, and it is life-tested past 6 million cycles and still working after. The breakaway lever (American and Crescent designs) gives up before the internals do, and the patented clutch lets the outside lever spin free when locked instead of transmitting force into the retractor. Inside it is a cast stainless steel retractor on bronze roller bearings, cast Zamac levers with a 1/2 inch return, and a 3-7/16 inch rose thru-bolted with two #10 epoxy-coated thru-bolts.

13) Is the Marks 195FEU keyed, and what keyway does it come in?

It comes with Marks "C" keyway 6-pin cylinders and two nickel-silver keys, or you can order it with an IC core housing if you are on a small format interchangeable core system and want to pin it into your existing masterkeying. If you are standardizing a building on one keyway, the IC housing is the route that keeps the 195FEU on the same key system as the rest of your openings.

14) I only need a plain push-pull lever on a closet or corridor door with no electric release. What should I buy instead of the 195FEU?

Don't pay for the electrification. The 195FEU is an access-controlled device and its non-electric equivalent in plain passage duty is something like the Cal-Royal CAL30 Calypso Series, a Grade 1 extra heavy duty passage lockset covering 1-3/8 inch to 2 inch doors, or the Orca Hardware OCL210 if Grade 2 medium duty is enough for the traffic. All three retract the latch by the lever at all times; only the 195FEU adds the electric unlock.

15) Does the Marks 195FEU lever have to be handed when I order it?

The rose is a 3-7/16 inch round thru-bolted with two #10 thru-bolts and the lock is a cylindrical bored device, so the mounting itself is symmetrical. What you do specify on the order is finish (US26 polished chrome or US10B oil-rubbed dark bronze), voltage (12VDC or 24VDC), backset if you are not at the standard 2-3/4 inch, cylinder type (Marks "C" 6-pin or IC core housing), the REX switch since it is not standard, and the K1704 spacer if the door is 1-3/8 inch.

16) Can I standardize a whole building on the Marks 195FEU, or do I mix it with mechanical locks?

Mix it. The 195FEU is the access-controlled opening: perimeter doors, server rooms, anywhere the panel needs to release the lever. Its ANSI function is F75, latch retracted by the lever at all times on the inside, so it is not a privacy or a classroom lock. For the bathrooms and offices behind it, the same-grade mechanical partners in the Cal-Royal Calypso line are the CAL20 privacy and CAL30 passage, both Grade 1 and both covering 1-3/8 inch to 2 inch doors, or the Dorma C853 Grade 1 entrance lever for keyed offices at 1-3/8 inch to 2-1/4 inch. Keeping the 195FEU on an IC core housing lets the electrified doors sit on the same key system as the rest.

17) Why do levers on our high-traffic doors keep snapping off, and does the Marks 195FEU solve that?

The usual failure is a rigid lever: someone hangs on it while the lock is secured, and the force goes straight into the retractor until something inside gives. The 195FEU attacks that two ways. The breakaway lever design, in both the American and Crescent styles, gives way under excessive abuse so less torque reaches the outside lever, and the patented clutch disengages the outside lever when the lock is secured so it spins freely without pulling on the latch at all. Behind it, a cast stainless steel retractor on bronze roller bearings takes 1,800 inch-pounds.

18) The opening only needs a lever that always retracts the latch, with no electrification. What is a simpler alternative to the Marks USA 195FEU?

A plain mechanical passage lever does that job. The Cal-Royal CAL30 Calypso Series is a Grade 1 extra heavy duty passage lockset with a Passage/Hall/Closet function, and it fits 1-3/8 inch to 2 inch doors, a wider range than the 1-5/8 inch to 1-7/8 inch the Marks USA 195FEU is designed for. Where medium duty is acceptable, the Orca Hardware OCL210 is a Grade 2 passage cylindrical lockset with the same Passage/Hall/Closet function. Both give you free lever operation without any power, wiring, or access control interface; neither can be released remotely the way the 195FEU can.

19) Our doors are a full 1-3/4 inch or thicker. Which access control locks fit where the Marks USA 195FEU needs a spacer?

The Marks USA 195FEU is designed for 1-5/8 inch to 1-7/8 inch doors, so 1-3/4 inch is inside its range and no spacer is involved; the K1704 spacer is only for 1-3/8 inch doors. If you are standardizing on 1-3/4 inch openings and want alternatives, the TownSteel XCE-2000 Series electronic keypad lockset and the XCE-9000 Series electronic classroom intruder keypad lockset are both Grade 1 heavy duty for 1-3/4 inch to 2 inch doors, and the Schlage XE360M is a Grade 1 wireless tubular lock with an offline push button function for 1-3/4 inch doors. Those three are classroom function locks, while the 195FEU is a passage function lever released electrically.

20) For restroom and office doors that need to lock from the inside, what do we specify instead of the Marks USA 195FEU?

The 195FEU is a Passage/Hall/Closet function lockset and has no inside locking. For a privacy opening, the Cal-Royal CAL20 Calypso Series is a Grade 1 extra heavy duty privacy lock for 1-3/8 inch to 2 inch doors, and the Alarm Lock Trilogy 4100 is a Grade 1 electronic cylindrical lock with a privacy function and keypad for 1-5/8 inch to 1-7/8 inch doors, the same thickness window as the 195FEU. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic cylindrical lock with a privacy function and keypad for 1-3/4 inch doors. Where medium duty suits, the Orca Hardware OCL240 is a Grade 2 privacy cylindrical lockset.

21) We already key the building on small format interchangeable core. Which electronic cylindrical locks work with that alongside the Marks USA 195FEU?

The Marks USA 195FEU is supplied with Marks C keyway 6-pin cylinders and two nickel-silver keys, with an IC core housing available. Among the electronic peers, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock stated as IC/SFIC compatible, and the BEST 9KZ EZ Series is an electronic keypad cylindrical lock with a key override function. On a mixed retrofit, matching the core format across the opening set matters more than matching the lock brand, so confirm the housing option when you order.

22) Will a Kwikset SmartCode 912TNL or a Lockey mechanical pushbutton knob lock do the same job as the Marks USA 195FEU?

They belong to a different service class. The Kwikset 912TNL ZW500 SmartCode is an electronic Tustin lever with Z-Wave, a keyed one side function, for 1-3/8 inch to 2 inch doors, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for 1-1/8 inch to 2 inch doors. Neither is driven by a building access control signal. The Marks USA 195FEU is a Grade 1 commercial lockset with electric fail-secure unlock at 24V/AC with bridge rectifier or 24V/DC at 0.21 Amps, UL Listed with a 3-hour fire rating and 6-million-cycle life testing. On a fire rated commercial corridor door tied to a controller, the Kwikset and Lockey units are not interchangeable with it.

23) How does the Marks USA 195FEU compare with the Stanley QCL150 on latch and strike prep?

They land close on prep. The Stanley Security QCL150 is a QCL100 Series entry lever, Sierra bent lever with rose, less cylinder, with a square 2-3/4 inch backset latch and a 4-7/8 inch x 1-1/4 inch ASA strike, and it is Grade 2. The Marks USA 195FEU also uses a 2-3/4 inch backset with a 4-7/8 inch ASA curved lip strike, number 1135, and a 1-1/8 inch x 2-1/4 inch front with a 9/16 inch deadlocking throw, at Grade 1. Same standard backset and ASA strike family, so a swap between them is mostly a matter of grade and whether the opening needs the electric release the Marks provides.

24) Is the SDC E75 an alternative to the Marks USA 195FEU for a door with no power run?

Yes, with a different control model. The SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control, built for 1-3/4 inch to 2-1/8 inch doors. It carries its own power and credential entry at the door, so no wiring run is needed. The Marks USA 195FEU is fail-secure and takes its release signal at 24V/AC with bridge rectifier, 24V/DC at 0.21 Amps, or 12V/DC, so it depends on a power supply and controller. Check the leaf: the E75 range starts at 1-3/4 inch, while the 195FEU covers 1-5/8 inch to 1-7/8 inch.

25) Which alternatives to the Marks USA 195FEU cover doors thinner than 1-5/8 inch without an added spacer?

The Marks USA 195FEU is designed for 1-5/8 inch to 1-7/8 inch doors and takes the K1704 spacer for 1-3/8 inch doors. If you would rather not add a spacer part on a thin leaf, the Cal-Royal CAL30 passage lockset and CAL20 privacy lockset are both Grade 1 extra heavy duty for 1-3/8 inch to 2 inch doors, the Dorma C150 covers 1-3/8 inch to 2-1/4 inch, and the Lockey 1600 heavy duty mechanical keyless knob lock with adjustable backset spans 1-1/8 inch to 2 inch. Those are mechanical or keypad units, so the electric release the 195FEU offers does not come with them.
