Definition of Compartment from 2016 NFPA 13 and 13R: A space completely enclosed by walls
and a ceiling. Each wall in the compartment is permitted to
have openings to an adjoining space if the openings have a
minimum lintel depth of 8 in. (203 mm) from the ceiling and
the total width of the openings in a single wall does not exceed
8 ft (2.44 m) in width. A single opening of 36 in. (914 mm) or
less in width without a lintel is permitted when there are no
other openings to adjoining spaces.
Is the word space and compartment used interchangeably in the above underlined locations, and is describing when different compartments are determined?
Does the definition mean said compartment can have(permitted) adjoining spaces and still be part of the compartment as long as they have a minimum lentil depth of 8 in.?
If a master bedroom in an apartment has two fire sprinklers in it but has another in a walk-in-closet as well as in the master bath--total of 4 fire sprinklers. The closet an master bath have lentil depths of 12 inches.
When calculating for up to 4 heads in the most demanding compartment do we include the fire sprinkler heads in the walk-in-closet and master bath, or are those considered separate compartments?
