The Schlage electrified ND Grade 1 Cylindrical lock offers offer superior energy efficiency and flexibility in wired electrified applications.

The Schlage electrified ND Grade 1 Cylindrical lock has been completely redesigned to offer superior energy efficiency and flexibility in wired electrified applications. It features universal input voltage and auto-detects 12 through 24 VDC for installation flexibility. Users can select mode of operation in the field by moving switch on lock chassis; Fail Safe (EL) or Fail Secure (EU). Request-to-exit (RX) can be added at any time using a RX kit. Low maximum current draw of 0.23 amps (230 mA) allows up to 8 locks on a single 2 amp power supply. Additionally, a holding current of 0.01 amps (10 mA) produces minimal heat, eliminating hot levers in electrically locking applications and allows for reliable operation in poorly ventilated wood doors.

All ND Series locks come in 10 finishes, five lever designs and use an ANSI 161 door preparation, commonly used with cylindrical locks. They are ideal for new construction applications.
