Kisi Two-Wire Adapter (Powered Device / PD)

Modern Access Control. Legacy Wiring. Zero Compromise.

The Kisi Two-Wire Adapter is a compact, efficient solution that enables you to bring Kisi’s modern access control to your existing infrastructure. Acting as the Powered Device (PD) in the two-wire system, this adapter receives both power and data from the Kisi Two-Wire Switch (PSE) and uses it to drive the Kisi Reader — all over a standard two-wire connection.

Ideal for retrofit scenarios, the adapter eliminates the need for complex rewiring, making upgrades fast, cost-effective, and minimally disruptive. Its low-profile, heatshrink-tubing design fits neatly in tight spaces, making installation quick and discreet.
