Input Fault LEDs:-
Each input contact has a yellow fault LED associated with
it. If the input is in a fault condition the LED will be
illuminated.

Output connection Wiring
The Ziton I/O unit has clean contact relay outputs
capable of switching 2A @ 24V DC. The location of the
output connections are shown in Figure 2.

On power up the relay outputs will be reset to output bit
state 0.
Output fail to safe mode
This function is enabled/disabled by loop address switch
8. Switch 8 to the 1 position enables this mode of
operation and switch 8 to the 0 position disables the
mode. As default this mode is disabled.
When the function is enabled, the relay outputs will
assume the output bit state 0 in the event of:-
• Communication loss to the Ziton loop interface
• Failure of any battery pack
Note: Switches 1 to 7 are not used
Input connection wiring
The location of the Ziton I/O unit's input connections are
shown in Figure 2. Connection details are shown in

Functional testing
When polled by a compatible panel, the Ziton I/O unit, in
its normal condition will return an analogue value of 90*.
