Re: IRC and smoke detectors

Discussion in 'Security Alarms' started by Michael B. Baker, Sep 6, 2004.

  1. That's the way it looks to me. IRC is adamant about using smoke alarms vs. smoke detectors.

    IRC-2003 SECTION R313 SMOKE ALARMS
    [F] R313.1 Smoke alarms. Smoke alarms shall be installed in
    the following locations:
    1. In each sleeping room.
    2. Outside each separate sleeping area in the immediate vi-
    cinity of the bedrooms.
    3. On each additional story of the dwelling, including base-
    ments 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.

    When more than one smoke alarm is required to be installed
    within an individual dwelling unit the alarm devices shall be in-
    terconnected in such a manner that the actuation of one alarm
    will activate all of the alarms in the individual unit. The alarm
    shall be clearly audible in all bedrooms over background noise
    levels with all intervening doors closed.

    All smoke alarms shall be listed and installed in accordance
    with the provisions of this code and the household firewarning
    equipment provisions of NFPA 72.

    [EB] R313.1.1 Alterations, repairs and additions. When
    interior alterations, repairs or additions requiring a permit
    occur, or when one or more sleeping rooms are added or
    created in existing dwellings, the individual dwelling unit
    shall be provided with smoke alarms located as required for
    new dwellings; the smoke alarms shall be interconnected
    and hard wired.

    Exceptions:
    1. Smoke alarms in existing areas shall not be re-
    quired to be interconnected and hard wired where
    the alterations or repairs do not result in the remov-
    al of interior wall or ceiling finishes exposing the
    structure, unless there is an attic, crawl space, or
    basement availablewhich could provide access for
    hard wiring and interconnection without the re-
    moval of interior finishes.

    2. Repairs to the exterior surfaces of dwellings are ex-
    empt from the requirements of this section.

    [F] R313.2 Power source. In new construction, the required
    smoke alarms shall receive their primary power from the build-
    ing wiring when such wiring is served from a commercial
    source, and when primary power is interrupted, shall receive
    power from a battery.Wiring shall be permanent and without a
    disconnecting switch other than those required for overcurrent
    protection.Smoke alarms shall be permitted to be battery oper-
    ated when installed in buildings without commercial power or
    in buildings that undergo alterations, repairs or additions regu-
    lated by Section R313.1.1.
