When deploying access control in high-density environments like data centers, the wiring approach can make a big difference in both installation complexity and long-term scalability.
Traditional access control systems rely on multiple conductors to support readers, REX, DPS, and electrified locks—requiring individual wiring runs from each cabinet back to a controller.
In contrast, a 4-wire cabinet lock with OSDP communication uses just two conductors for data and two for power—allowing multiple locks to share a single RS-485 bus, dramatically reducing cabling and simplifying deployment.

Key Takeaway:
In cabinet deployments with dozens—or even hundreds—of racks, small wiring efficiencies scale quickly.
By reducing cabling, simplifying setup, and streamlining connections, 4-wire cabinet lock systems help IT teams and integrators move faster and operate smarter.
Fewer conductors mean fewer potential failure points, faster installs, and better long-term scalability—without compromising on control, monitoring, or security.
