Product Description

PR621 access controller



The PR621 series controllers are designed for the most popular access control solutions. They can be used in both standalone and networked installations of up to 1,000 users. All PR621 series controllers are equipped with an RS485 communication interface, which can be used both for their programming and for communication in a network system. An access control system based on PR621 controllers can be managed either locally via COM/USB serial ports or remotely via a WAN/LAN computer network.
