Does anyone know if the Uniform Codes (UBC, UFC, UMC, etc) or NFPA 72 requires shutdown of all HVAC systems bringing outside air into an area on activation of the alarm system, either by the sprinkler flow switch or an area smoke detector? We have a large open office area (cubicles) served by a dozen rooftop air conditioning units.
Our fire alarm contractor insists that the code requires shutdown of all the HVAC units on activation of the building fire alarm.
Comments please. Thanks
