Ubiquiti UA-Retrofit-Reader-B – UniFi Access Retrofit Reader
Overview
The Ubiquiti UA-Retrofit-Reader-B is a black UniFi Access indoor/outdoor access reader designed for deployments using the UniFi Retrofit Hub and existing access-control cabling. It provides OSDP-based reader communication with NFC card and keyfob access, Apple/Google Wallet support, Mobile Unlock, and Touch Pass functionality. It is intended for upgrading compatible access-control installations without replacing existing reader wiring. The reader communicates through RS-485 using OSDP v2 and operates from 12V DC with a maximum power consumption of 2.5W. NFC operates at 13.56 MHz with a read range of less than 30 mm. The enclosure combines polycarbonate and aluminum alloy, while the included mounting hardware uses stainless steel.
Technical Information
The UA-Retrofit-Reader-B supports NFC technologies including ISO 14443A, ISO 14443B, ISO 15693, NFC Tags 1–5, MIFARE Classic, MIFARE Plus, MIFARE Ultralight, and MIFARE DESFire. Bluetooth 4.1 is also supported, while the reader provides a factory-reset button, speaker, and multicolor R/G/B/W LED indicators. Its 117 x 45 x 13.3 mm form factor and 82 g weight support compact wall or gang-box installations. The reader is rated IP55 for indoor/outdoor deployment and operates from -30°C to 50°C with 5–90% non-condensing humidity.
Compatibility and Deployment
The UA-Retrofit-Reader-B is designed to connect to the UniFi Retrofit Hub using existing reader cabling. Ubiquiti documents compatibility with Retrofit Hub installations that use existing RS-485 wiring from previous Wiegand or OSDP deployments. Retrofit Readers can be automatically discovered and adopted by the UniFi Retrofit Hub. This reader is appropriate for access-control upgrades where existing cabling can be retained. It should not be treated as a standalone door-lock controller; the UniFi Retrofit Hub provides the control interface for the connected door hardware.
Applications
Existing access-control system modernization Commercial office entrances Retail and business facilities Educational and institutional access points Indoor and outdoor controlled doors Retrofit installations using existing reader cabling UniFi Access deployments requiring NFC and mobile credentials
