Yes. The lock supports dual voltage operation. Current draw is 420 milliamp at 12 volt direct current and 210 milliamp at 24 volt direct current.
Additional Information
- On external doors and gates, installers typically protect cable entry points and ensure the mounting face is flat to maintain full holding force and reduce misalignment.

- If frame clearance is limited, an L bracket or Z bracket can be used to position the magnet and armature correctly.
