Detectors in New Construction.
All of the smoke alarms/detectors specified in A-8-1.2.1.a for
existing construction are required and, in addition, a smoke
alarm/detector is required in each bedroom.
A-8-1.2.1.c Are More Smoke Alarms/Detectors Desirable?
The required number of smoke alarms/detectors might not
provide reliable early warning protection for those areas
separated by a door from the areas protected by the
required smoke alarms/detectors. For this reason, it is
recommended that the householder consider the use of
additional smoke alarms/detectors for those areas for
increased protection. The additional areas include the
basement, bedrooms, dining room, furnace room, utility
room, and hallways not protected by the required smoke
alarms/detectors. The installation of smoke alarms/detec-
tors in kitchens, attics (finished or unfinished), or garages
is not normally recommended, as these locations occasion-
ally experience conditions that can result in improper
operation.
