CL93DEU Electrified Lock — Voltage and Compatibility
The Command Access CL93DEU is a Grade 1 fail-secure cylindrical lock based on the BEST 93K commercial locking platform. It has a 15D lever with D rose, 626 satin chrome finish and SFIC preparation, less core. The exterior lever is controlled for authorized electrical entry, while the inside lever must remain mechanically operable for exit.
Catalog Review – Product-Specific Notes
BEST 93K Core and Voltage Selection
Both CL93DEU options use the 15D lever, D rose, satin chrome finish and SFIC less-core preparation; choose the 12V or 24V configuration to match the factory electrical design. The core, control key and operating keys must be verified against the facility’s interchangeable-core system.
Confirm the cylindrical door prep and any BEST 93K compatibility requirements before a retrofit. During commissioning, test exterior access under authorized control, positive relatching, intended fail-secure behavior on power loss and free interior mechanical egress.
BEST 93K Retrofit and Facility Keying Considerations
The CL93DEU is a Grade 1 fail-secure electrified cylindrical lock based on the BEST 93K platform. The listed configurations have a 15D lever, D rose and 626 satin chrome finish, with SFIC preparation less core. Select the 12V or 24V model to suit the specified access-control power scheme.
Specification Checklist
- Keying: Supply the correct SFIC core and keys separately, confirm the small-format core specification and make sure the facility’s control-key procedure matches the hardware schedule.
- Fail-secure behavior: The outside lever remains locked during a power failure, while the inside mechanical exit function must remain operable. Confirm required ingress, override and egress operation with the door’s life-safety design.
- Electrical integration: Verify nominal voltage, permissible power source, operating current, conductor capacity and transfer method against the selected factory SKU.
- Mechanical fit: Check 93K-compatible cylindrical lock preparation, latch and strike, bore, backset, door thickness, handing and finish.
Acceptance Checklist
During commissioning, verify mechanical key operation with the installed core, outside lever unlocking with authorized power, relocking after the control signal ends, secure function after loss of power, positive latch engagement and uninterrupted inside egress. Access-control electronics, separate power supply, SFIC core and door wiring are not included unless specifically stated by the seller.
| Voltage | Manufacturer SKU | Electrical function | Cylinder preparation |
|---|---|---|---|
| 12V | CL93DEU 15D 626 12V | Fail-secure / power-to-unlock | SFIC, less core |
| 24V | CL93DEU 15D 626 24V | Fail-secure / power-to-unlock | SFIC, less core |
Key Technical Differences
- Factory voltage: Choose 12V or 24V to match the specified power supply and access-control output; verify the AC/DC and current requirements against the selected model's cut sheet.
- Interchangeable core: An SFIC core is not included in the less-core configuration; confirm operating/control keys, core format and facility keying system.
- Fail-secure function: The outside lever remains secured during power loss, unlike a corresponding fail-safe unit. Verify mechanical override and ingress behavior in the door design.
- Physical compatibility: Confirm backset, bore, latch and strike, door thickness, handing and lockcase preparation before purchasing.
- Installation testing: Verify mechanical keying, electrical unlock, loss-of-power state, inside mechanical exit and proper closing/latching.
Typical Uses and Exclusions
Suitable for properly specified high-use commercial entry and institutional controlled-access openings. An interchangeable key core, controller, power supply, wiring and power-transfer components are separate unless specifically listed as included in a chosen package.
Before You Order
- Match the exact factory model and variant to the project hardware schedule; model suffixes indicate important operational differences.
- Confirm electrical supply, wiring, control interface, local codes and compatibility with the installed equipment.
- Use current manufacturer wiring diagrams, cut sheets and installation instructions; test the complete door assembly after installation.
Choose the correct factory configuration from the variant selector. Detailed technical and installation information for each manufacturer part number is provided below.

12V — CL93DEU 15D 626 12V
The Command Access Technologies CL93DEU Grade 1 Electrified Cylindrical Lock is built on the BEST 93K Series commercial lock platform and provides electronically controlled exterior entry with free mechanical egress. This factory-configured lockset has 15D lever and D-rose trim, 12V fail-secure (power-to-unlock) operation, SFIC preparation, less core, and 626 / US26D Satin Chrome finish. It is suited to high-use commercial openings where controlled access and dependable mechanical exit are required.
Key Features and Benefits
- Grade 1 heavy-duty construction: Electrified BEST 93K-style cylindrical lock platform for demanding commercial and institutional openings.
- Fail-secure (EU) exterior lever: The outside lever remains secured without electrical power and is electrically released by an authorized access-control signal. The interior lever remains mechanically free for immediate egress.
- 15D lever design: 15-pattern lever with D-style rose, for compatibility with the specified BEST 93K-style hardware configuration.
- SFIC prep, less core: Prepared for a compatible small-format interchangeable core. The interchangeable core and operating/control keys are not included. Coordinate a compatible core and keying system separately.
- Factory-specified 12V power: The CL93 series supports separate 12V or 24V AC/DC configurations; this is the 12V factory model. Use an appropriately rated supply and current factory wiring instructions.
- Efficient continuous-duty electrification: CL93-series literature lists approximately 250 mA at 12V and 3 W power consumption, with a bridge rectifier supporting a compatible AC or DC source.
- 626 Satin Chrome: US26D commercial architectural finish for coordinating door and frame hardware.
- Non-REX specification: This part number does not include an optional request-to-exit switch. Order a designated REX configuration when interior-lever monitoring is needed.

Fail Secure vs. Fail Safe
CL93DEU = fail secure: The exterior lever remains locked during a power outage and can be electrically unlocked for authorized entry when power is supplied. This is different from a CL93DEL fail-safe model, which is designed to release the outside lever when power is removed. The interior lever must continue to provide code-compliant mechanical egress on the completed opening.
Installation and Selection Checklist
- Confirm the door hardware schedule calls for a CL93DEU 12V fail-secure cylindrical lock, 15D lever and 626 finish.
- Coordinate the SFIC less-core prep with the facility's key system. Verify core format, control key, operating keys and proper core retention; the core is sold separately.
- Confirm bore preparation, door thickness, latch backset, strike, handing and mounting requirements against the latest CL93 installation template.
- Provide a properly rated 12V AC/DC source, compatible controller or relay, low-voltage wiring and an approved electrical power transfer where required.
- Test fail-secure exterior entry, mechanical key access using the installed SFIC core, unrestricted interior egress, latch engagement, and loss-of-power behavior.
- Verify the complete opening complies with applicable accessibility, fire-rated-door, emergency egress and access-control requirements.
