‐
1.1.1
Smoke
detectors
used
with
this
system
should
be
installed
in
accordance
with
Chapter
2
of
the
National
Fire
Alarm
Code,
ANSI/NFPA
72
(National
Fire
Protection
Association,
Batterymarch
Park,
Quincy,
MA
02269)
which
reads
as
follows:
2
‐
1.1.2
Smoke
alarms
shall
be
installed
outside
of
each
separate
sleeping
area
in
the
immediate
vicinity
of
the
bedrooms
and
on
each
additional
story
of
the
family
living
unit
including
basements
and
excluding
crawl
spaces
and
unfinished
attics.
In
new
construction,
a
smoke
alarm
shall
be
installed
in
each
sleeping
room.
For
family
living
units
with
one
or
more
split
levels
(i.e.,
adjacent
levels
with
less
than
one
full
story
separation
between
levels),
a
smoke
alarm
shall
suffice
for
an
adjacent
lower
level,
including
basements.
(Exception:
Where
there
is
an
intervening
door
between
one
level
and
the
adjacent
lower
level,
a
smoke
alarm
shall
be
installed
on
the
lower
level.)
•
Ceiling
mounted
smoke
alarms
should
be
located
in
the
center
of
the
room
or
hall,
or
not
less
than
4
inches
from
any
wall.
When
the
alarm
is
mounted
on
a
wall,
the
top
of
the
alarm
should
be
4
to
12
inches
from
the
ceiling.
•
Do
not
install
smoke
alarms
where
normal
ambient
temperatures
are
above
100°F
(37.8°C),
or
below
40°F
(4°C).
Also,
do
not
locate
alarm
in
front
of
air
conditioners,
heating
registers,
or
other
locations
where
normal
air
circulation
will
keep
smoke
from
entering
the
detector.
A
‐
2.5.2.1
Smoke
Detection:
Are
More
Smoke
Alarms
Desirable?
The
required
number
of
smoke
alarms
might
not
provide
reliable
early
warning
protection
for
those
areas
separated
by
a
door
from
the
areas
protected
by
the
required
smoke
alarms.
For
this
reason,
it
is
recommended
that
the
residential
user
consider
the
use
of
additional
smoke
alarms
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.
The
installation
of
smoke
alarms
in
kitchens,
attics
(finished
or
unfinished),
or
garages
is
not
normally
recommended,
as
these
locations
occasionally
experience
conditions
that
can
result
in
improper
operation
or
false
alarms.
NOTE:
Smoke
alarms
are
not
to
be
used
with
detector
guards
unless
the
combination
has
been
evaluated
and
found
suitable
for
the
purpose.
