from the building wiring when such wiring is served from a commercial source.
Wiring shall be permanent and without a disconnecting switch other than that
required for overcurrent protection. Smoke alarms may be solely battery-powered
when installed in existing buildings, or in buildings without commercial power,
or in buildings which under go alterations, repairs or additions subject to

from the building wiring where more than one smoke alarm is required to be
installed shall be interconnected in such a manner that the activation of one
alarm will activate all of the alarms.
