A project that contains a light hazard office space with a dry-pipe sprinkler system, and a 900 sqft area with sloped ceilings (about a 5/12 pitch). Per NFPA 13, the remote area should increase by 30% for the dry system (NFPA 13-2013 Section 11.2.3.2.5) and another 30% for the slope (NFPA 13-2013 Section 11.2.3.2.4). However, does the fact that only 900 sqft of the entire remote area is sloped impact the overall size of the remote area at all? Curious in other's opinions.

When conducting means of egress calculations, is there a standard way to round? For instance, if the square footage of a room suggests 48.1 people, is the occupant load always rounded (conservatively) to 49 people? Or does rounding follow standard convention, where 0.50 and up rounds up, and everything below rounds down?

Is there an easy way to recognize the fire alarm circuit class: A, B, C, D, E, N, or X? That is, is there a way to determine the class, just by looking at the diagram or plan of the circuit?
