Hello,
Upon duct smoke detection, a main breaker panel is wired to trip which serves other equipments such as split systems, and exhaust fans rather than tripping the individual breaker that serves the HVAC unit. I think this is wrong because NFPA 90A says to shut down the respective unit associated with the duct detector. However, I see no harm in doing it this way. What are some of your thoughts on this?
