Has anyone tried to write a rule for the Duty and Standby Fans?
Fan 1 - has 1 output and 1 input (for trip status)
Dampers 1 and 2 - has 2 output and 2 inputs
Fan 2 - 1 has output and 1 input (for run status)
Dampers 3 and 4 - has 2 output and 2 inputs

The rule below executes accordingly when an alarm is active. But if the alarm is not active and Duty Fan Trip Status becomes active, (rules Q5A and Q6A will execute) the standby dampers would open and the fan would start bypassing rules QA1, QA2, QA3 and QA4.

What should I do with my rule to open the Standby dampers and turn on the standby fan only if the 'smoke and-group' and Duty Fan Trip status are both active?
