The Smoke Control Support (UL-864-UUKL) option adds the Emergency Mode Network Input and the Smoke Control Sequencing for UL-864-UUKL State Generator module. In the State Selection Table, you can create state values for each Output Controller to provide normal control, pressurize, depressurize, purge, or shutdown. For example, if the Emergency Mode Network Input is set to shutdown, you can set all of the Output Controller states to the desired condition in the State Selection Table.
