Marks USA 195RFEU/26D – Frequently Asked Questions

1) What happens to the Marks 195RFEU lock when the power goes out?
It stays locked. Fail secure means the outside lever remains locked on loss of power, so the opening keeps its security when the access control system drops. Egress is unaffected: the inside lever always retracts the latch. If your application needs the door to release and free-wheel on a power failure, for example an opening tied into a fire alarm release, fail secure is the wrong choice and you want a fail safe device instead.
2) Does the Marks USA 195RFEU come in 12 volt or 24 volt?
Both. The 195RFEU is ordered as either 12VDC or 24VDC, and each voltage is available in US26 polished chrome or US10B oil-rubbed dark bronze. Four combinations total, so pick the voltage your power supply or access control panel puts out and then the finish.
3) Will the Marks 195RFEU latch into the strike prep I already have in the frame?
The 195RFEU ships with strike #1135, a 4-7/8 inch ASA curved lip strike, which is the standard commercial frame prep. The latch front measures 1-1/8 x 2-1/4 inches with a 9/16 inch deadlocking throw. If your frame is already cut for a 4-7/8 inch ASA strike and a 1-1/8 x 2-1/4 inch latch face, it drops in. A frame prepped for a small T-strike or a 2-3/4 inch full lip strike will need reworking.
4) Is the Marks USA 195RFEU rated for a 3-hour fire door?
Yes. The 195RFEU is 3-hour fire rated and UL Listed, and it is ANSI/BHMA Grade 1. The deadlocking latch is part of what makes it usable on a rated assembly. It is also ADA compliant, so the lever meets accessibility requirements on public-side openings.
5) Should I run a wired electric lockset like the Marks 195RFEU or a standalone battery keypad lock?
The 195RFEU is a wired solenoid lock, ANSI F75 function, that unlocks on a signal from an access control panel. Choose it when the opening is already going onto a card reader or panel and you want central control and no batteries to change. If there is no wiring to the door and no panel, a standalone lock makes more sense: the Alarm Lock Trilogy T2 DL2700 is a Grade 1 battery keypad cylindrical lock covering the same 1-5/8 to 1-7/8 inch door range, and the Schlage NDEB is a Grade 1 wireless ENGAGE lock for 1-5/8 to 2 inch doors. If you want wired but a different platform, the SDC Electra 7200 is a solenoid cylindrical lock with dual 12/24VDC.
6) The door is 2 inches thick. Which cylindrical locks handle it instead of the Marks USA 195RFEU?
The Marks USA 195RFEU is built for doors 1-5/8 to 1-7/8 inch, with a K1904 spacer for 1-3/8 inch, so a 2 inch door falls outside it. The Dorma C150 Grade 1 heavy-duty cylindrical lock in entry/office function covers 1-3/8 to 2-1/4 inch, and the Dorma C853 entry keyed single cylinder lever lockset is Grade 1 over the same 1-3/8 to 2-1/4 inch range. The Cal-Royal CAL30 Grade 1 passage lockset reaches 2 inch. On the electrified side, the SDC Electra 7200 covers 1-3/4 to 2 inch and the TownSteel XCE-2000 Grade 1 keypad lockset covers 1-3/4 to 2 inch.
7) What is the closest alternative to the Marks USA 195RFEU for a fail-secure electrically controlled cylindrical lock on a hardwired access-controlled opening?
The SDC Electra 7200 Series solenoid controlled cylindrical lock is the nearest hardwired peer, and like the Marks USA 195RFEU it runs on dual voltage 12/24VDC. The 195RFEU is a Grade 1 cylindrical lock with a 9/16 inch latch throw and a 1-1/8 by 2-1/4 inch front, and it accepts door thicknesses of 1-5/8 to 1-7/8 inch. The SDC 7200 covers doors 1-3/4 to 2 inch, so on a 1-5/8 inch door the Marks unit is the one that fits and on a 2 inch door the SDC is. Both are wired devices controlled from an access control panel rather than from a keypad at the door.
8) If I do not want to run wire to the door, what standalone lock can I use instead of the Marks USA 195RFEU?
The 195RFEU is an electrically unlocked lockset that has to be powered and controlled from a panel. Where pulling wire to the opening is not practical, 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 covers the same 1-5/8 to 1-7/8 inch door thickness range the Marks unit does. The SDC E75 Series is another battery-powered keypad cylindrical lockset, though it is built for 1-3/4 to 2-1/8 inch doors. Standalone units hold their credentials at the door instead of taking a release signal from a head-end.
9) Why does the Marks Survivor Series lever not droop like the levers on my other doors?
Lever droop comes from the lever hanging on the retractor and wearing the chassis over years of traffic. The Survivor Series chassis uses a stainless steel clutch and bronze roller bearings that disengage the lever from the retractor when the lock is secured, so nothing loads the mechanism when someone pulls on a locked lever. That is the reason it tests past 3.6 million cycles, roughly 300 percent over the BHMA Grade 1 requirement. On a high-traffic corridor or a stairwell door where you are replacing sagging levers every couple of years, that is the difference that matters.
10) Is the Marks 195RFEU a classroom or storeroom lock?
No. The 195RFEU is an F75 passage function, meaning the levers retract the latch at all times mechanically; the security is in the electric unlock signal, not a key cylinder function. If you need a mechanical classroom or storeroom function at the door, look at a keyed function instead: the Dorma C853 is a Grade 1 keyed entry lever, and the TownSteel XCE-2000 is a Grade 1 classroom electronic cylindrical lockset for 1-3/4 to 2 inch doors.
11) What do I need to specify when ordering the Marks 195RFEU?
Four things settle the order: voltage (12VDC or 24VDC), finish (US26 polished chrome or US10B oil-rubbed dark bronze), backset (2-3/4 inch standard, 2-3/8 inch also offered), and the interchangeable core, which is specified separately. Add the K1904 spacer only if the door is 1-3/8 inch. The 4-7/8 inch ASA strike #1135 is already in the box, so you do not order that separately.
12) Can the Marks 195RFEU go into a standard 161 cylindrical door prep?
It is a cylindrical (bored) lockset, not a mortise lock, so it installs in a bored cross-bore prep rather than a mortise pocket. The levers mount on thru-bolted roses 3-7/16 inches in diameter with two spring-loaded #10 thru-bolts. If your doors are prepped for mortise locks, this will not drop in and you need a mortise body instead.
13) Which alternatives to the Marks USA 195RFEU take an interchangeable core?
The Marks USA 195RFEU is an IC lockset. Among the cylindrical peers, the Alarm Lock Trilogy T2 DL2700 is IC/SFIC compatible and is a Grade 1 standalone electronic lock covering the same 1-5/8 to 1-7/8 inch door thickness as the Marks unit, and the BEST 9KZ EZ Series electronic keypad cylindrical lock includes a key override function. For a locksmith already keying a building on a small format core, those are the peers that keep the same core in the door.
14) I need a credential reader at the door rather than a panel-released lock. What replaces the Marks USA 195RFEU?
The 195RFEU takes its unlock signal from an access control panel and carries no reader of its own. Where the credential has to be presented at the opening, the Schlage NDEB is a Grade 1 heavy duty ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader for doors 1-5/8 to 2 inch, which overlaps the Marks unit's 1-5/8 to 1-7/8 inch range. The TownSteel FCE-2000 is a Grade 1 standalone motorized cylindrical lockset with RFID for 1-3/4 inch doors, and the Schlage XE360M is a Grade 1 wireless tubular lock with a smart mobile reader, also 1-3/4 inch. These put the reader and the decision at the door; the 195RFEU keeps both at the panel.
15) Can I standardize a facility on a Grade 2 lever instead of the Marks USA 195RFEU?
The Marks USA 195RFEU is ANSI/BHMA Grade 1 and UL Listed. The Grade 2 levers in the same cylindrical family are the Orca Hardware OCL210 passage, OCL250 entrance and OCL240 privacy, all medium duty, and the Dorma CL701 Grade 2 passage lever. Those are non-electrified mechanical trim, so they cover the doors in a facility that are not on access control while the 195RFEU handles the controlled openings. For a spec that calls out Grade 1 throughout, the Cal-Royal CAL30 passage and CAL20 privacy locksets and the Dorma C150 hold Grade 1 in the same non-electrified role.
16) Is a mechanical pushbutton lock like the Lockey 2830 an alternative to the Marks USA 195RFEU?
The Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for doors 1-1/8 to 2 inch, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset over the same 1-1/8 to 2 inch range. Both control entry with a code set inside the lock and no power at all. The Marks USA 195RFEU is a lever lockset with an electric unlock that a panel drives, and its lever meets ADA requirements, where the Lockey units are knob trim. Pick the Lockey where there is no power and no reason to tie the door into a system; pick the 195RFEU where the opening has to be released remotely and the trim has to be a lever.
17) The Marks USA 195RFEU comes with a 4-7/8 inch ASA strike. Which alternatives match an existing frame prep?
The 195RFEU ships with Strike #1135, a 4-7/8 inch ASA curved lip strike, and uses a 2-3/4 inch backset with a 1-1/8 by 2-1/4 inch latch front. Frames already cut for a 4-7/8 inch ASA strike also suit the Stanley QCL150, which uses a square 2-3/4 inch backset latch and a 4-7/8 by 1-1/4 inch ASA strike, and the Stanley QTL230E, supplied with an adjustable square latch and a 4-7/8 by 1-1/4 inch ANSI strike. Where the frame is prepped for the smaller ANSI cutout instead, the Stanley QCL200 comes with a 118F ANSI 1-1/8 by 2-3/4 inch strike. Confirm the lip length against the existing frame before ordering.
18) Do any alternatives to the Marks USA 195RFEU record who came through the door?
The 195RFEU is released by an access control panel, so any record of an entry lives in that system rather than in the lock. If the audit has to sit in the lock itself, the Alarm Lock T3 DL3075 is a Grade 1 electronic cylindrical lock with an audit trail and keypad access, and the Alarm Lock DL5200 is a double-sided electronic cylindrical lock with 100 user capacity and battery operation, covering 1-5/8 to 1-7/8 inch doors, the same range the Marks unit accepts. The DL5200 reads a code on both sides, which the 195RFEU does not do.
