Firex Smoke Alarm i4618 - Manual (Page 5)

• Install Smoke Alarms on tray-shaped ceilings (coffered
ceilings) on the highest portion of the ceiling or on the
sloped portion of the ceiling within 12” (305mm) verti-
cally down from the highest point (see figure 4).
MOBILE HOME INSTALLATION
Modern mobile homes have been designed and built
to be energy efficient. Install smoke alarms as recom-
mended above (refer to RECOMMENDED LOCATIONS
and FIGURES 1 and 2).
In older mobile homes that are not well insulated com-
pared to present standards, 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 prevent the smoke from
reaching an alarm mounted on the ceiling. In such
units, install the smoke alarm on 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).
If you are not sure about the insulation in your mobile
home, or if you notice that the outer walls and ceiling
are either hot or cold, install the alarm on an inside
wall. For minimum protection, install at least one
alarm close to the bedrooms. For additional protec-
tion, see SINGLE FLOOR PLAN in FIGURE 2.
WARNING: TEST YOUR SMOKE ALARM OPERA-
TION AFTER R.V. OR MOBILE HOME VEHICLE HAS
BEEN IN STORAGE, BEFORE EACH TRIP AND AT
LEAST ONCE A WEEK DURING USE.
2. LOCATIONS TO AVOID
• In the garage. Products of combustion are present
when you start your automobile.
• Less than 4” (10cm) from the peak of an “A” frame
type ceiling.
• In an area where the temperature may fall below
40ºF or rise above 100ºF, such as garages and unfin-
ished attics.
