Ubiquiti UniFi Access UACC-Retrofit-PoE-2Wire

The Ubiquiti UniFi Access Retrofit PoE Over 2-Wire Adapter (UACC-Retrofit-PoE-2Wire) is an intelligent networking accessory engineered to simplify and modernize the deployment of UniFi Access systems in buildings with legacy infrastructure. This compact adapter allows Ethernet and PoE signals to be transmitted over existing two-wire cabling, eliminating the need to install new network cables while enabling high-performance access control connectivity.

Designed for retrofitting older buildings, historical properties, and facilities with embedded two-wire electrical systems, the UACC-Retrofit-PoE-2Wire is an ideal solution for environments where installing new CAT5e or CAT6 Ethernet cabling is impractical, costly, or prohibited due to structural limitations. It enables installers to bring modern UniFi Access technologies into buildings using existing wiring pathways—saving time, labor, and material costs while maintaining network reliability and performance.

The device operates in a paired configuration, with one adapter installed near the PoE source and another at the destination endpoint, such as a UniFi Access Reader or UniFi Intercom device. It supports full-duplex 10/100 Mbps Ethernet communication over two-wire connections, providing both data transmission and power delivery to compatible UniFi Access devices. The included accessories simplify installation and enable quick mounting within junction boxes or behind wall panels.

As part of the UniFi Access product family, the UACC-Retrofit-PoE-2Wire integrates seamlessly into centralized UniFi management systems. Once installed, administrators can use the UniFi Access Controller to monitor device status, manage configurations, and ensure reliable performance across all connected components. The adapter is compatible with IEEE 802.3af/at PoE standards, making it suitable for powering a range of low-power network devices across the access control environment.

Constructed with high-quality materials and engineered to deliver consistent performance, the UACC-Retrofit-PoE-2Wire is compact, reliable, and energy efficient. It is suitable for both indoor and controlled-environment installations and is designed to operate over long distances with minimal signal degradation.

In summary, the UACC-Retrofit-PoE-2Wire is a transformative solution for bringing modern UniFi Access control capabilities into buildings with outdated wiring. By offering Ethernet and PoE over two-wire infrastructure, it bridges the gap between legacy installations and contemporary networked access systems—enabling faster, cleaner, and more cost-effective deployments without compromise.
