This equipment should be installed in accordance with the National Fire Protection Association’s
Standard 72 (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
For your information, the National Fire Protection Association’s Standard 72, Section 11.5.1
covering required protection in One- and Two-Family Dwelling Units, reads as follows:
11.5.1.1 Smoke Detection. Where required by applicable laws, codes, or standards for the
specified occupancy, approved single- and multiple-station smoke alarms shall be installed as
follows:
(1) In all sleeping rooms
Exception: Smoke alarms shall not be required in sleeping rooms in existing one-
and two-family dwelling units.
(2) Outside each separate sleeping area, in the immediate vicinity of the sleeping
rooms
(3) On each level of the dwelling unit, including basements
Exception: In existing one- and two-family dwelling units, approved smoke alarms
powered by batteries shall be permitted.
A.11.8.4 Heat Detection.
General. While Chapter 11 does not require heat detectors as part of the basic protection scheme,
it is recommended that the householder consider the use of additional heat detectors for the same
reasons presented under A-11.8.3. The additional areas lending themselves to protection with
heat detectors are the kitchen, dining room, attic, (finished or unfinished), furnace room, utility
room, basement, and integral or attached garage. For bedrooms, the installation of a smoke
detector is recommended over the installation of a heat detector for protection of the occupants
from fires in their bedrooms.
Further, the California State Fire Marshal states that the minimum number of required smoke
alarms is not enough to give the earliest warning under all conditions. The California State Fire
Marshal states that: “Early warning fire detection is best achieved by the installation of fire
detection equipment in all rooms and areas of the household as follows: A smoke alarm installed
