Detector Hvac
Why would a hard wired Smoke detector trip a Circuit Breaker?
Smoke detector is wired to kill 24 Volts to 2 HVAC units.
If I'm reading your question correctly, you want to know WHY a smoke detector would be connected to trip 2 HVAC units.
In the event of a fire, the last thing you want is the HVAC system to be pumping fresh air to the fire and circulating the smoke and poisonous fumes through-out the rest of the building.
Many commercial buildings are designed so an operation of the fire detection equipment shuts down the HVAC system. (as well as the elevators)
