Zeta Addressable Input Unit (ZIU)

The ZIU is used to interface any equipment that has a volt free normally open contact to a Zeta Analogue Addressable fire alarm control panel

In accordance with our policy of continual improvement of our products, the ZIU interface now includes a built in loop short circuit isolator.

The unit has internal LED indications for Loop isolator active, fault on input and Alarm (Panel controlled).  During the system set-up, the lid can be removed from this box to allow these LEDs to be viewed.
