The Zeta ZAIO-MI is a loop-powered Fyreye MKII addressable input/output module with a built-in short circuit isolator, for Zeta MKII protocol addressable fire panels. It monitors a voltage-free input and at the same time switches a local SELV relay output, for example to control lifts during an alarm, start a fire pump or stop ventilation fans. It is housed in a 2 gang size enclosure supplied with a back box for surface mounting indoors.
