We wanted to know if a Category 2 Class A facility for horse riding requires heat detection. The roof line is very high and i am concerned about long term service. NFPA150 states Fire alarms are required in all Class A facilities and any Class B facility with sleeping quarters. Fire alarm detection devices are required to be installed within all human sleeping areas, any air-conditioned space, and all storage areas that exceed 100 square feet. Looking for more insight or if this allows us to not have to install in the riding area. The horses are not kept in this facility they are in a different structure with stables.
