Intent 1:
To supersede the requirements of Sentence 9.10.18.2.(2) and permit a fire alarm system in only a portion
of a building, if certain conditions are met.
These conditions are to limit the probability that:
- the separations between the portions of the building
will have insufficient fire resistance, which could lead to the spread
of fire from one portion of the building to another portion, and
- fire and combustion by-products will spread from one
portion of the building to another portion through openings in the
separation between building portions.
This is to limit the probability of harm to persons in the
other portion of the building.
