Schlage L Series Electrified Mortise Lock

The Schlage L Series Electrified Mortise Lock has long been the benchmark for mortise locks. The L Series Electrified Mortise Lock offers tremendous flexibility which allows it to meet the needs of most every wired application. 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).

All new modular RX switch monitors the inside lever with enhanced detection level that balances security with lever sensitivity; it can be added at a later time without opening the lock case. Low maximum current draw of 0.4 amps (230 mA) allows multiple locks on a single 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.
