The designer used the room design method (laundry, telephone room, and corridor), special consideration method - residential heads (bedrooms), and the density/area method (day room, computer lab). He is using NFPA 13, and not NFPA 13R. Basically he needs to increase the fire resistance rating of walls equal to water supply duration for room design method. Or he can re-design area to use density/area method. My question is if he chooses to use the density/area method, can he still use special consideration method - residential heads, which allows four heads inside bedrooms for calculation?
