If the isolator needs to be PERMANENTLY bypassed, connect the – OUT to the spare –IN terminal. To temporarily bypass the isolator (eg for a DVM cable continuity check), fit a shorting link to position J1. The ZIU is now addressed by 3 rotary switches, one for 100`s one for 10`s, one for units. Select an address between 1 & 126. (The picture shows 037) PCB Identification The same PCB is used for The ZIU (input only), ZIOU (Input with volt free relay output), and ZSCC (sounder circuit controller). Each PCB will have an Identification mark (tick or “X”) to show which model it is. Description The Zeta addressable Input Unit (ZIU) is used to interface external equipment which has a volt free NORMALLY OPEN relay output to any Zeta Analogue Addressable fire alarm system. The input is monitored with a 47k end of line resistor. The unit has a built in loop short circuit isolator to help keep the unit operational in the event of a problem on the addressable loop wiring. It has 3 indication LEDs on the front of the unit. One for Alarm, one for local fault and one for addressable loop fault (Isolator active).

All it`s indication LEDs are under its own control. In the event of an alarm, it will set input bit 0 to an active condition, as well as setting it’s analogue value to 64 to indicate it’s activation. Other information Like all electronic equipment, at the end of it`s working life this unit should not be disposed of in a refuse bin. It should be taken to a local reprocessing site as per the guidelines of the WEEE directive, for correct disposal.
