Corbin Russwin CLX33903 NZD 626 – Frequently Asked Questions

1) What happens to the Corbin Russwin CLX33903 when the power drops?
It unlocks. The CLX33903 is a fail-safe electrified cylindrical lock, so cutting power releases the outside lever for free access, which is what you want on egress and life-safety openings tied to a fire alarm or access control release. If you need the opening to stay locked during a power loss, you need a fail-secure version instead, not this one.
2) Will the CLX33903 electrified lever lock fit a 1-3/8 inch door?
Not as it ships. The standard CLX33903 covers 1-3/4 inch to 2 inch doors (44 to 51mm). Corbin Russwin lists a D138 option for 1-3/8 inch doors and a D214 option for doors over 2 inch up to 2-1/4 inch, so a thinner or thicker door has to be specified as that option at order time. A patented adjustable push/turn button handles the thickness adjustment within the range.
3) What backset and stile width does the CLX33903 cylindrical lock need?
Standard prep is a 2-3/4 inch (70mm) backset with a 4-1/2 inch (114mm) minimum stile. Optional backsets of 2-3/8 inch, 3-3/4 inch and 5 inch are available if your existing prep or a narrow-frame condition calls for it. Door prep follows ANSI/SDI A250.14, so it drops into a standard 161 commercial prep.
4) Will the CLX33903 latch into the strike already in my frame?
The standard latch is a stainless steel deadlatch with a 1/2 inch (13mm) throw, square corner front, 2-1/4 x 1-1/8 inch, on a 2-3/4 inch backset. It ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 inch with 1-1/4 inch lip to center. If your frame has a standard ANSI 4-7/8 inch strike prep, the existing strike will accept it. For a fire opening needing more throw, a 3/4 inch (19mm) deadlocking fire latch is an option.
5) What voltage and current does the CLX33903 electrified lockset draw?
It runs on 12VDC or 24VDC, with an operating range of 10.2 to 26.4VDC on the CLX33900 platform. Draw is 10mA continuous with a 500mA peak at either voltage, so size the supply for the inrush, not the holding current. Wiring terminates in an ElectroLynx 8-pin molex connector, which plugs straight into an ElectroLynx electric hinge or transfer harness. Operating temperature is -13F to 151F.
6) Is the CLX33903 approved for a fire-rated door in a hospital or school?
Yes. It is ANSI/BHMA A156.2 Grade 1, UL/cUL 3-hour rated, NFPA 80 compliant, UL294 listed as an electrified access control device, and meets ADA A117.1. It is also windstorm and hurricane certified. For a labeled opening, specify the 3/4 inch deadlocking fire latch.
7) Is there a mechanical Grade 1 cylindrical lever lock to use instead of the Corbin Russwin CLX33903 on openings with no power at the door?
The Corbin Russwin CLX33903 is an electromechanical cylindrical lock, so it needs a 12VDC or 24VDC supply run to the opening and a transfer hinge or power transfer device. Where no power is available, a keyed mechanical Grade 1 cylindrical lever lock covers the opening instead: the Dexter C1000 Series classroom lever lock is Grade 1 with a classroom function and fits doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 Series classroom security lever lock is Grade 1 with keyed control from both sides over the same door thickness range. Both are purely mechanical, so access control scheduling and remote release are lost.
8) Can a keypad lever lock replace the Corbin Russwin CLX33903 for standalone credential access?
Not equivalently. The Corbin Russwin CLX33903 is a fail-safe electrified cylindrical lock that unlocks on loss of power and is released by an external access control system over 12VDC or 24VDC, which is what lets it tie into card readers, egress and fire alarm interfaces. Standalone keypad levers such as the Delaney LP250 electronic keypad leverlock, which is Grade 2, or the Lockey 2835 mechanical pushbutton keyless lever lock for doors 1-3/16 inch to 2 inch, carry their own code entry and no system connection, so they cannot be remotely released or unlocked on alarm.
9) Do I need to order the CLX33903 handed for a left or right swing?
No. It is non-handed, so one lock covers either swing and you can stock a single part number across a building instead of splitting left and right hand inventory.
10) Can I get the CLX33903 with request-to-exit monitoring?
Yes. Besides the standard configuration, a Request to Exit version is offered, which reports lever use back to the access control panel so you can shunt an alarm on authorized egress. Both configurations come with the Armstrong (AZD) or Newport (NZD) lever in 626 satin chrome.
11) What keyway and cylinder does the CLX33903 come with, and can I use my own cores?
It ships with a conventional brass cylinder, 6-pin L4 keyway, 0-bitted. The chassis is built to take any cylinder format Corbin Russwin offers, from fixed core through interchangeable core, so an existing small or large format IC keying system can be carried onto these doors by specifying the matching cylinder.
12) Is a Grade 1 electrified cylindrical lock like the CLX33903 tough enough for a heavily abused door?
It is tested well past the Grade 1 minimums: 20 million cycles verified by UL, over 3,100 in-lb of abusive locked lever torque (2.6 times the ANSI requirement) and over 1,600 lbs offset lever pull (8 times ANSI). The Lever Release freewheeling design lets the locked lever spin rather than break, which is the failure mode on school and dorm doors.
13) Is a keypad lever lock an alternative to the CLX33903 for a door with no wiring?
If you cannot get power or a cable to the opening, a standalone keypad is the practical route, not an electrified lock. The CLX33903 needs a 12 or 24VDC supply and an ElectroLynx connection to work at all. For unwired doors ZenSupply carries mechanical keypad leversets such as the Lockey 1150 (1-1/8 to 2 inch doors) and Lockey 2835 (1-3/16 to 2 inch doors), and electronic keypad leversets like the Delaney LP250. None of those integrate with an access control panel or release on fire alarm the way the fail-safe CLX33903 does.
14) What is a good Grade 1 lever lock to pair with the Corbin Russwin CLX33903 on the non-access-controlled doors of the same project?
To keep lever style and Grade 1 durability consistent across a run of doors where only some are electrified, the Corbin Russwin CLX33903 handles the controlled openings and non-keyed Grade 1 cylindrical levers handle the rest. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, is fire rated, and fits doors 1-3/8 inch to 2-1/4 inch, which spans the CLX33903 standard 1-3/4 inch to 2 inch range. The Falcon T101 is also Grade 1 heavy duty passage. For a dummy trim on an inactive leaf, the BEST 9K Series 1DT is Grade 1 non-keyed heavy duty.
15) For a lower-cost commercial lever on interior doors instead of the Corbin Russwin CLX33903, what are the Grade 2 options?
The Corbin Russwin CLX33903 is Grade 1 and electrified, built for high-traffic controlled openings. On interior doors that only need mechanical function at medium duty, Grade 2 cylindrical levers apply: the Hager 2580 is a Grade 2 storeroom cylindrical lock with Withnell lever for doors 1-3/8 inch to 2 inch, the Hager 2525 is a Grade 2 commercial entry lever over the same range, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with deadlocking latchbolt. The Falcon B511CP6D is Grade 2 medium duty with an entry/office function.
16) Which lever locks look like substitutes for the Corbin Russwin CLX33903 but will not work on a commercial access-controlled opening?
Two groups. Residential-duty levers carry a lighter grade than the CLX33903 Grade 1 rating: the Kwikset 200BRNL Breton passage lever is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, the Master Lock RL Series keyed entry lever is Grade 3, and the Cal-Royal AUS00 entrance/office lever is Grade 3. Decorative trim sets are the second group: the Baldwin Estate 5103 passage lever and the Emtek Classic Brass Cortina dummy pair are trim-driven levers, and a dummy has no latch at all, so it cannot secure or release an opening.
17) Which lever styles and finish does the CLX33903 come in?
Two lever designs are offered, the Armstrong (AZD) and the Newport (NZD), both on the D rose, in 626 satin chrome. If you are matching existing openings in a building, the lever code is the detail to check, since both mount identically on the same chassis.
18) Is a Grade 1 passage lever like the Design Hardware X75 an alternative to the Corbin Russwin CLX33903?
Only for openings that need no locking. The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors, so it latches but never locks. The Corbin Russwin CLX33903 is keyed with a single cylinder, uses a 6-pin L4 keyway 0-bitted brass cylinder, and adds electrified fail-safe release. Where a keyed override is required alongside the electric function, a passage set is not a substitute.
