The Zeta ZAIO/230 is a Fyreye MKII addressable mains switching input/output module with a built-in short circuit isolator. It monitors a field contact and provides a mains-rated relay output, so third-party equipment can be interfaced with a Zeta MKII protocol fire alarm panel. It is loop powered, supplied with a back box for surface mounting, and designed for indoor use only. The address is set with its DIP switch.
