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.
