SDC SK-L90 Field Electrification Kit | For Schlage L9000 Mortise Locksets

The SDC SK-L90 is a precision-engineered field electrification kit designed to convert a standard Schlage L9000 mechanical mortise lock into a high-performance electronic access control solution. This kit is the industry-leading solution for commercial door security, allowing facility managers to upgrade existing hardware to "Fail-Secure" or "Fail-Safe" operation without the high cost of a total lockset replacement. By utilizing the existing lock body, the SK-L90 serves as an efficient and sustainable solution for door restoration in high-traffic commercial, institutional, and government buildings.

Seamless Field Retrofit and Performance

The SDC SK-L90 provides a streamlined path to modernizing your facility’s security infrastructure. It acts as a proactive solution for door surface repair by eliminating the need for new door prep or modified drilling:

• Direct Schlage Compatibility: Specifically engineered for the Schlage L9000 series mortise lockset, ensuring a perfect mechanical fit and reliable electronic actuation.
  
• Dual Voltage Versatility: The kit is designed to operate on either 12VDC or 24VDC power supplies. It features a low current draw of 600mA at 12VDC and 300mA at 24VDC, making it compatible with most standard access control systems.
  
• Selectable Operational Modes: Depending on your life safety and security requirements, this kit can be configured for Fail-Safe (locked when energized) or Fail-Secure (unlocked when energized) functionality.
  
• Maintains Mechanical Integrity: By electrifying the existing lock body, you maintain the high-quality feel and durability of the Schlage L9000 while gaining the ability to integrate with card readers, keypads, and remote release buttons.

Industrial-Grade Reliability and Installation Benefits

Upgrading your door hardware with the SDC SK-L90 provides a high-value solution for door restoration with professional-grade benefits:

• Eliminate Costly Replacements: Retain your expensive Schlage trim and mortise body. This kit saves significant material costs compared to purchasing a pre-electrified lockset from the factory.
• Labor-Efficient Install: The field-installable design allows for quick conversion on-site, reducing door downtime in critical areas like stairwells, offices, and entryways.
  
• Stabilized Power Connection: For the most reliable installation, it is recommended to use an electrified hinge or power transfer loop to bring power to the door, ensuring a permanent solution for commercial door security.
• Enhanced Door Stability: The kit integrates with the internal levers of the lock, which can be further secured using thru bolts on the trim to prevent hardware loosening over time—a vital solution for door edge reinforcement.
