Hi Friends, Our project for pharma including Lab, production line, warehouse and also with office, training room etc. So I wolud like to double check if smoke detector should be required for office, meeting room, training room and Lab area as per NFPA72? My understanding it should supply smoke detector for all these area except toilet room but now design firm only design smoke detetor for equipment room (such as elctrcial room, IDF, chiller room etc,.). As below sample, there is smoke in Electrcial room with red rectangle and no detector for office area as green rectangle. By the way those rooms will be full coverage by sprinkler system. So is my understanding wrong? Thanks!
