Kidde PI2010 - Manual (Page 3)

• Locate an alarm in every sleeping room.
• Locate an alarm in every room where
electrical appliances are
operated (i.e. portable heaters or humidi-
fiers).
• Locate an alarm in every room where
someone sleeps with the door closed.
The closed door may prevent an alarm
not located in that room from waking the
sleeper.
• Smoke, heat, and combustion products
rise to the ceiling and spread horizontally.
Mounting the smoke alarm on the ceiling
in the center of the room places it closest
to all points in the room. Ceiling mount-
ing is preferred in ordinary residential
construction.
• For mobile home installation, select loca-
tions carefully to avoid thermal barriers
that may form at the ceiling. For more
details, see MOBILE HOME INSTALLATION
below.
• When mounting an alarm on the ceiling,
locate it at a minimum of 4” (10 cm)
from the side wall (see figure 1).
• When mounting the alarm on the wall,
use an inside wall with the top edge of
the alarm at a minimum of 4” (10 cm)
and a maximum of 12” (30.5 cm) below
the ceiling (see figure 1).
• Put smoke alarms at both ends of a hall-
way or large room if the hallway or room
is more than 30 ft (9.1 m) long. For large
rooms, one smoke alarm is recommended
for every 500 square feet of floor space.
• In homes that are not well insulated,
extreme heat or cold can be transferred
from the outside to the inside through
poorly insulated walls and roof. This may
create a thermal barrier which can pre-
vent the smoke from reaching an alarm
mounted on the ceiling. If you are not
sure about the insulation in your home,
or if you notice that the outer walls and
ceiling are either hot or cold, install the alarm on an inside wall. In
such homes, install the smoke alarm with the top edge of the alarm
