LOGIC & CAUSE/EFFECT MATRIX

// Emergency Response Matrix 

IF INPUT:     L2_Smoke_Detector_04 == ALARM

THEN OUTPUT:     -> Activate_Strobes(Zone_2, Zone_3)
                            -> Start_Evac_Message(Language="EN", Floor=2)
                           -> Trigger_Relay(HVAC_Shutdown_L2)
                           -> Delay(3000ms) -> Close_Fire_Doors(L2)

 

{  }

Complex boolean logic allows for "Double Knock" scenarios (requiring two devices to activate before dumping gas suppression) and phased evacuation strategies to prevent stairwell congestion.
