EDA Zerio Plus Network Controller, EDA-Z6020
For larger systems, where the radio range of a system is not greater enough, or more than 240 devices are required, several systems can be installed and then linked together, forming a single system.
Should a display not be required in a sub-system, then a Network Controller, EDA-Z6020 can be used instead.
This is essentially a control panel but with no visible display or accessible buttons. The controls remain locked inside the panel and are only used by an engineer to configure the sub-system. It has the same functionality as a standard control panel.
