APPLICATION:

Manual silencing switches for fire alarm systems, in buildings described in Sentence 1.3.3.2.(1) of Division A in which fire alarm systems are installed.
This also applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] in which fire alarm systems are installed.

INTENT:

To limit the probability that unauthorized persons will have access to the silencing switch, which could lead to the premature silencing of alarm signals in a fire situation, which could lead to persons misinterpreting whether or not a real fire situation exists, which could lead to delays in evacuation or moving to a safe place, which could lead to harm to persons.
