Overview

SL1 (lever) and SK1 (knob) trims are specifically designed with multiple safety facets including recessed trim, sloped surfaces and concealed fastening hardware to reduce the risk of injury or death due to ligature strangulation in hospitals, behavioral health facilities and detention centers. Additionally, the motorized operation is also quieter than solenoid-based designs to help contribute to healing environments.  Optional key override adds an anti-barricade safety feature on two functions helping prevent self-harm situations by allowing the key to override a  thumbturn being held in a locked position. 

Ideal for use on:    

  • Low- to medium-risk behavioral health facility doors
  • Secured-use hospital room doors
  • Detention center doors

Security

  • Ligature-resistant designs positively contribute to healing environments - lever style is also ADA compliant 
  • Tested and certified to ANSI/BHMA Grade 1 operational and security standards
  • UL listed for 3-hour fire door; spring-loaded fusible link inside lock case provides fail secure mode in case of fire   
  • Available lead lining for use in X-ray or other rooms with radiation concern
  • Deadbolt functions include anti-saw pin in bolt to prevent cut-through
  • Lock monitoring options include request to exit (RX), latchbolt (LX), door postion (DPS), and deadbolt (DM) (availability varies by function)
  • Patented Everest 29™ S123 keyway is provided standard which prohibits unauthorized key duplication 
  • Restricted geographically exclusive Primus upgraded security options offer advanced key control and exceptional physical security

 

Aesthetics

  • Smooth, sloped surface design with concealed fastening 
  • Available in 630 Satin Stainless Steel finish with an antimicrobial coating option
  • Deadbolt functions also feature a ligature-resistant thumbturn
  • Low holding current produces minimal heat, eliminating “hot levers” in electrically locking applications
  • Quiet, motorized activation      
  • See HSLR ligature-resistant mortise trim for other designs in health care solutions

 

Functions

  • Nine keyed and non-keyed electrified functions
  • Two electrified functions offer optional key override of the inside thumbturn when it is being held in the locked position to stop unwanted barricade situations
  • 22 additional non-electrified SK1/SL1 ligature-resistant trim functions available (see separate web page for details)

 

Installation simplicity

  • Auto detects 12 or 24V DC
  • Low maximum current draw allows multiple locks on a single power supply
  • Case-mounted switch allows field selectable fail safe/fail secure setting    
  • Modular design allows RX feature to be added at a later time without opening the lock case

 

Built to Last

  • Two piece anti-friction tongue in latch bolt reduces wear
  • Breakaway spindle keeps door secured in the event of vandalism
  • Every Schlage lock undergoes intensive testing to determine its ANSI grade level including: cycle, resistance, door impact, warped door and bolt strength tests 

Electrified functions listed beginning with L/LV can be ordered with or without Vandlgard option. Both functions are field selectable Electrically Locked (EL) or Electrically Unlocked (EU). Optional key override is a safety feature, available on two functions, that allows the outside key to retract the deadbolt and/or latchbolt, depending on function, to override the inside thumbturn when it is being held in the locked position.
