PR621-CH access controllers are designed for hotel applications. They can be used either in standalone or integrated access systems for up to 1000 users. PR621-CH units are equipped with RS485 interface which can be use for both programming and online which can be use for both programming and online communication in networked system. Access control system based on PR621-CH controllers can be managed locally through COM/USB serial port or remotely by computer network WAN/LAN.
