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.c. New and replacement 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.(8) The failure of any nonreliable or short-life component which renders the alarm inoperative shall be readily apparent to the occupant of the sleeping unit without the need for a test. Each smoke alarm shall detect abnormal quantities of smoke that may occur and shall properly operate in the normal environmental condition.(9) Equipment shall be installed in accordance with the manufacturer's recommendations.(10) Installed fire warning equipment shall be mounted so as to be supported independently of its attachment to wires.(11) All apparatus shall be restored to normal immediately after each alarm or test.(12) Smoke alarms shall be located as follows:a. On the ceiling or wall outside of each separate sleeping area in the immediate vicinity of bedrooms.b. In each room used for sleeping purposes.c. In each story within a dwelling unit, including basements but not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels and without an intervening door between the adjacent levels, a smoke alarm installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level.Iowa Admin.
