Exception. Smoke alarms are permitted to be solely battery-operated
in buildings where no construction is taking place, buildings that
are not served from a commercial power source and in existing areas
of buildings undergoing alterations or repairs that do not result

noise levels with all intervening doors closed.

Exceptions:
(a)
Interconnection is not required in buildings which are not undergoing
alterations, repairs or construction of any kind.

Smoke alarms in existing areas are not required to be interconnected
where alterations or repairs do not result in the removal of interior
wall or ceiling finishes exposing the structure, unless there is an
attic, crawl space or basement available which could provide access
