Schlage ND Series Electrified Cylindrical Lock
Product Overview and Specifications
Overview
Many of the most advanced electronic access control systems still rely on the strength and functionality of the mechanical lock hardware on the door. Schlage ND Series electrified locks feature Schlage's most robust cylindrical design, built for performance, security, and durability. It is a "beyond Grade 1" lock in terms of strength and can be used as part of an integrated system or as a standalone solution with a buzzer or other device as the controller.
The Schlage ND cylindrical lock uses a motor instead of a solenoid to provide quiet operation and energy efficiency. The maximum current draw of 0.24 amp allows more locks to run off a single power supply. A low, 0.010 amp holding current eliminates any potential for hot levers in electrically locking applications or in electrically unlocking applications where the door is left open for long periods of time. ND Series can be quickly and easily installed and is compatible with various key systems for field adaptability. It integrates seamlessly with other ND Series hardware, which includes both purely mechanical and fully electronic solutions.
When it comes to access control, mechanical components are just as important as their electronic counterparts. The Schlage ND Series provides versatility and easy installation to complete your access control system.

Recommended Applications
The wired electrified ND Series is ideal for new construction and high-traffic areas where hardwired power ensures continuous operation and where electrified door prep, hinges, and wiring can easily be incorporated into the building. The electrified ND Series is regularly used as part of an access control system for high-security areas, or independently in areas that require a remote access switch.

Vandlgard® Functions
Some functions feature Vandlgard locked lever protection. It allows the outside lever to rotate freely up and down when locked to limit the ability of vandals to apply excessive force to the chassis, helping to prevent damage to internal components.
