Busy Indication Configuration

The digital outputs of a Remote I/O Unit may be assigned as 'Busy Outputs'. Each such output may be
assigned to correspond to the busy state of any Router output or group of outputs. In the case of a group of
outputs, it operates as an OR function of the busy state of the outputs, i.e. if any of them are busy, the digital
output is driven.
It is possible to configure which input, or group of inputs, will cause the 'busy' indication to be given on a
particular Router output.
In this way the 'busy' output may be driven conditional on which input source is routed. This facility is useful
for provide feedback of Alert and Evacuate DVA operation on a zonal basis.
To Configure a Remote I/O Unit Digital Output as 'Busy Output':
1. Select the Remote I/O Unit to be programmed by selecting its unit address on the RS485 bus.
Menu: Configuration System Router Ctrl Remote
The unit address should match the address set by a switch internal to the unit.
2. Select the Remote I/O Unit digital output and then program it for 'Busy-Indication'.
Menu: Configuration System Router Ctrl Remote Unit address <n> Digital Out
3. For each Router output program which input, or group of inputs, will cause 'busy' indication on this
particular output.
4. Inputs can be:
a. Any of the local inputs (SLAVE).
b. Any of the Audio Control Unit inputs (CTRL).
