			 smoke detection listed under UL 268 has been installed. Any single-station
			 smoke alarm or multiple-station smoke alarm installed on or after April 1,

			 equipment to be installed in conformity with this chapter shall be approved and
			 used for the purposes for which they are intended. Any smoke alarm installed on
			 or after April 1,2010, in compliance with this chapter, including a replacement
			 of an existing smoke alarm, shall be listed in accordance with UL 217. Existing
			 dual sensor smoke alarms may be maintained until replacement is recommended by
			 the manufacturer or upon failure.
(4) A combination system, such as a household
			 fire warning system whose components may be used in whole or in part, in common
			 with a nonfire emergency signaling system, such as a burglar alarm system or an
			 intercom system, shall not be permitted or approved, except for one- or
			 two-family dwellings.
(5) All power
			 supplies shall be sufficient to operate the smoke detector alarm for at least
			 four continuous minutes.

			 Single-station battery-operated or battery backup smoke alarms shall be
			 replaced in accordance with the manufacturer's instructions.

a. In new buildings and additions constructed
			 after July 1, 1991, required smoke alarms shall receive their primary power
			 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
			 subrule 210.3(2).
b. New and
			 replacement smoke alarms installed after May 1, 1993, which receive their
			 primary power from the building wiring shall be equipped with a battery
			 backup.

			 smoke alarms installed after July 1, 2016, which receive their primary power
			 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.
d. After June 30, 2021, a battery-powered
			 smoke alarm listed in accordance with UL 217 that is newly installed or
			 replaces an existing battery-powered smoke alarm must be powered by a
			 nonremovable, nonreplaceable battery that powers the alarm for at least ten
			 years. The battery requirements of this subrule do not apply to a fire alarm,
			 smoke detector, smoke alarm, or ancillary component that is electronically
			 connected as a part of a centrally monitored or supervised alarm system; that
			 uses a low-power, radio frequency wireless communication signal.
