I have a renovation project in a hospital where smoke detectors were installed in an Intensive Care Unit in the corridors. The client decided he wanted smoke detectors in any corridor that haa a nursing station in it because this is how all his facilities are designed. To my knowledge this is not required by code. The issue is the corridor ceiling is a flat ceiling with lay in acoustical tiles, in the corridor there are a couple of skylights approximately 6'x6'x7' (WxDxH) in size. These skylights have a peaked top. The inspector is saying the corridor smoke detectors need to be installed at the highest point. However, I don’t see anything in the NFPA 72 (2013) that addresses sky lights. In NFPA 72 (2013) Section 17.7.3.3 this does address the placement of smoke detectors for peaked ceilings, but the overall corridor ceiling is flat and only the small areas of skylight are peaked. Anyone have any experience with this type of application with skylights and smoke detectors in a hospital corridor? Any insight is appreciated.
