I remember I saw one NFPA code explain according to the square feet in storage room we do not need smoke detector, can somebody remember that code.
As far as I know, NFPA never required smoke detection in storage occupancies. A storage room might require smoke detection if they are part of an occupancy that requires them, such as day care occupancy or assembly occupancy with hazardous areas.
Can you provide more information regarding your question? For example, will the building be protected by a sprinkler system? Is total coverage smoke detection a requirement? What's going to be stored in the storage room?
Felipe Martinez are you familiar with IBC and LSC requirements regarding which areas in which occupancies require smoke detectors?
I work in the Middle East with a lot of British Consultants who specify smoke detectors literally everywhere they can (i.e. everywhere in every occupancy, above and below ceilings except smokey, dusty and wet areas). It's complete overdesign and has nothing to do with NFPA. It's so entrenched that people think it's a requirement.
