Zeta Addressable Input-Ouput Units
The Zeta addressable input output units (ZIOU
and ZIOU/230) are used to interface external
equipment to any Zeta addressable fire alarm
system.
It has a switch monitoring input with a 47K End-of-Line
resistor and volt free SELV relay output.
There are two versions available, one for switching
low voltage (ZIOU) and the other for switching mains
(ZIOU/230).
As with all addressable interfaces, the outputs are
controlled by the panel to which they are connected.
Consequently the interfaces will behave differently on
different panels, i.e some may allow the outputs to be
programmed whilst others will have a default “pre-
programmed” operation.
