The custom digital out function is configured by selecting "Annunciator Setup", "Outputs Setup", then "Custom Digital Outs".
Custom Digital Output Setup
Select the top button of the page to select an output to configure. Only outputs that have no function or already have a custom digital out can be selected.
For a given output, select the top button of the lower section to define a condition when the output should be on. This can be any condition dependent on other inputs. Also available is a delay before/after the sensor condition is true/false for the output to activate or deactivate.
