ASSA ABLOY’s Hi-O™ (Highly Intelligent Opening) connects electronic door components together over a controller area network (CAN), allowing the parts to communicate and be monitored. Hi-O enables devices to exchange and share encrypted information. Every device (the lock, exit device, electric strike, proximity reader, door operator, push button, etc.) is connected through a four-wire cable.
With Hi-O, intelligence is built into each device instead of one centralized logic unit, creating a plug-and-play system. Among its advantages, expansion of the Hi-O door system is simplified because all new devices are automatically identified on the network.
