Can anyone tell me what the fire alarm/smoke detector requirements for a dental office are? The plans I'm working off for a bid just say "Smoke detectors as required by NFPA". This is a dental office with 5 exam rooms, along with pano xray area, waiting room, reception, bathroom, and mechanical room. Can these just be interconnected smoke detectors or does it have to be a complete fire alarm system with pull stations and flashing lights, etc.?
