Sloped Ceiling Installation:
Install smoke alarms on sloped, peaked or cathedral ceilings
at, or within 0.9 m (3’) of the highest point (measured
horizontally). NFPA 72 states “Smoke alarms in rooms with
ceiling slopes greater than 0.3 m – 2.4 m (1’ to 8’)
horizontally shall be located on the high side of the room”.
Do not place the alarm in the peak of an “A” frame type
ceiling (see Figure 1 and 2).
Operating and Installation Instructions
Mobile Homes:
Modern mobile homes have been designed and built to be
energy efficient. Install Smoke/CO alarms as recommended
previously (refer to Recommended Installation Instructions
and Figure 1).
In older mobile 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
cause a thermal barrier, which can prevent smoke from
reaching an alarm mounted on the ceiling. In such mobile
homes install your Smoke/CO Alarm on an inside wall with
the top edge of the alarm at a minimum of 10 cm (4”) and
a maximum of 30.5 cm (12”) 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 your alarm on an inside wall ONLY!
THIS EQUIPMENT SHOULD BE INSTALLED IN
ACCORDANCE WITH THE NATIONAL FIRE PROTECTION
ASSOCIATION’S STANDARD 72.
