Corbin Russwin CL33905-KEYED-24AD Grade 1 Fail Secure Electrified Cylindrical Lever Lock, 24VAC/DC

Remote-Controlled Fail Secure Access for High-Security Commercial Doors

The Corbin Russwin CL33905-KEYED-24AD is a Grade 1 fail secure electrified cylindrical lever lock engineered for demanding commercial access control applications. Built on the proven CL3300 Series Cylindrical Lockset platform with Lever Release™ Mechanism, this unit operates on 24VAC/DC (also available in 12VAC/VDC) and is hard wired at 150mA. Designed for 1-3/4" to 2" door thickness with a 2-3/4" backset, it delivers remote locking and unlocking capability while meeting life safety codes. The self-contained integral solenoid allows installation in a modified cylindrical door prep, and a conventional 6-pin cylinder with mechanical override ensures access is never compromised during a power outage.

Corbin Russwin CL33905 NZD 626 24AD – Frequently Asked Questions

1) What happens to a CL33905 fail secure lever lock when the power goes out?
It stays locked. Fail secure means the outside lever remains locked with no power applied, so a power loss leaves the opening secure rather than open. Egress from the inside is unaffected, and a conventional 6-pin cylinder gives you mechanical key override so you can still get in during an outage. If your code official or life safety plan requires the door to release on power loss (many stairwell re-entry and controlled egress schemes do), you want the fail safe version of the CL33900 Series instead.
2) How much current does the Corbin Russwin CL33905 draw, and what power supply do I need for it?
At 24VAC/DC the lock pulls 150mA on a continuous duty solenoid, and it's hard wired, not battery powered. Size the supply for 150mA per lock plus whatever else is on the circuit, and remember continuous duty means it draws that current the entire time the door is energized, not just at the moment of release. The same lock is built in a 12VAC/VDC version that draws 250mA, so if you're standardizing on a 12 volt supply, order that one rather than trying to run this one down-voltage.
3) Will the CL33905 latch into the strike that's already in my frame?
The standard latch is a 686F17 deadlatch with a square corner front measuring 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset, throwing 1/2 inch. It ships with a 217L13 ANSI curved lip strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. If your frame already carries a standard ANSI 4-7/8 inch strike prep, the latch drops into it. Where the existing front is round corner or a different size, the face prep in the door edge won't match and you'll need to reprep or use the supplied strike. On fire rated openings there's an optional 3/4 inch throw fire latch.
4) Can I order the Corbin Russwin CL33905 to work on my existing key system instead of a separate key?
Yes. The lock takes a conventional 6-pin cylinder as standard, and you can order it prepped for a Corbin Russwin large format interchangeable core in 6-pin (CL6) or 7-pin (CL7), less core, for small format interchangeable core less core, or as LC with no conventional cylinder at all if you're supplying your own. Keying is specified on the order as keyed different or keyed alike across multiple locks. If you're running an existing masterkey system, order the less core or LC version and pin it into your system.
5) Is the Corbin Russwin CL33905 rated for heavy traffic, and what standard does it meet?
It's certified to ANSI/BHMA A156.2 Series 4000, Grade 1, the heaviest cylindrical lockset classification, and it carries UL-cUL listing, ANSI A117.1 accessibility, and California State Fire Marshal listing. That combination is what most institutional and government specs call for on stairwells, tenant entries, and controlled areas. The chassis is steel with a zinc dichromate coating for corrosion resistance, and the latchbolt is stainless steel.
6) Can I get a Corbin Russwin CL33905 with a 3-3/4 inch or 5 inch backset for a wide rail door?
Yes, 3-3/4 inch (95mm) and 5 inch (127mm) backsets are optional against the 2-3/4 inch (70mm) standard. Those come up on doors with a wide lock rail or where a pull needs clearance from the lever. There's also an optional thickness range above 2 inches, up to 2-1/4 inches (57mm), for heavy or clad leaves. Both are order-time options, not field adjustments, so measure the existing bore-to-edge before you specify.
7) How do you get power into a cylindrical lock like the CL33905 on a swinging door?
Power has to cross from the frame to the door leaf, so the CL33905 needs an electric hinge or a door loop feeding the lock. Corbin Russwin puts an ElectroLynx 8-pin quick connect on all their electrified products, so the lock plugs into a matching ElectroLynx harness rather than being spliced in the field. Plan that transfer point into the frame prep before the door is hung, because retrofitting it afterward means pulling the door.
8) What stops someone from forcing the outside lever on an electrified lock like the CL33905?
The Lever Release mechanism handles that. When the lock is in its locked state the outside lever rotates freely instead of resisting, so wrenching on it doesn't transmit force into the chassis. Anti-rotational through-bolts at the 6 and 12 o'clock positions keep the trim from being twisted off the door, and independent return springs stop the lever from sagging over time, which is the usual failure on high-traffic levers. The auxiliary latchbolt deadlocks the main bolt when the door is closed so it can't be shimmed or loided.
9) What lever styles and finishes does the Corbin Russwin CL33905 come in for matching existing door hardware?
Three lever designs are offered on the electrified CL33905: Armstrong (AZD), Newport (NZD), and Princeton (PZD). Finishes run to fourteen: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E dark oxidized satin bronze equivalent, 613L dark oxidized oil-rubbed, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, BSP black suede, and WSP white suede powder coat. For a building already standardized on Corbin Russwin, matching the lever and finish code off an existing door gets you a visual match on the electrified opening.
10) Should I use an electrified cylindrical lock or a standalone keypad lock for controlling a door?
It comes down to whether the door needs to be controlled from somewhere else. The CL33905 is hard wired at 150mA and unlocks on a signal from an access control system, card reader, or remote release, which is what you want on stairwells, tenant entries, pharmacies, and data rooms where credentials and audit sit at the head end. A standalone keypad lever like the Lockey 1150, which fits 1-1/8 to 2 inch doors, or the Delaney LP250 electronic keypad leverset needs no wiring at all, and for a single door with a shared code that saves the whole cost of power transfer and a supply. Standalone gives you no remote release and no central control.
11) I only need a keyed storeroom lever, not an electrified one. What Grade 1 cylindrical lever should I look at instead?
If nothing about the opening needs remote release, skip the electrified chassis entirely and its power supply with it. The Dexter C1000 Series covers Grade 1 keyed cylindrical functions including Entry/Office and Classroom, both listed for 1-3/8 to 1-3/4 inch doors, and the Falcon T Series and K Series are heavy duty Grade 1 cylindrical levers. For lighter duty on interior openings, the Hager 2580 is a Grade 2 storeroom lever for 1-3/8 to 2 inch doors. The electrified CL33905 only earns its cost where an access control system is actually releasing the door.
12) Does the CL33905 electrified lock still allow people to get out of the room if the door is locked?
Free egress is always available. The inside lever retracts the latch mechanically regardless of whether the solenoid is energized, which is what lets an electrified cylindrical lock be used on stairwell and controlled egress openings while still meeting life safety code. The electrification only controls the outside lever. That's the same principle behind the CL3352 Classroom Intruder function in the family, which is a double-cylinder lockset with always-free egress.
13) Is there a version of the Corbin Russwin CL3300 cylindrical lock with an antimicrobial coating for a healthcare facility?
MicroShield antimicrobial coating is available on the platform under option code C. On patient room, clinic, and food service doors where the infection control spec calls for a treated touch surface, that's the suffix to add to the order. It's a coating option on the lever and trim, so it doesn't change the backset, thickness range, or electrical draw of the lock.
