• For mobile home installation, select locations carefully to avoid thermal barriers that may form at
the ceiling. For more details, see MOBILE HOME INSTALLATION section.
• When mounting an alarm on the ceiling, locate it at a minimum of 10 cm (4”) from the side wall
(Figure 7-A).
• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a mini-
mum of 10 cm (4”) and a maximum of 30.5 cm (12”) below the ceiling (Figure 7-A).
• Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more
than 9.1m (30 ft) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at least 0.9m (3ft) from the highest
point (measured horizontally). See Figure 7-C.
• Industry experts recommend a CO alarm be installed on each level of the home-ideally on any
level with fuel burning appliances and outside of sleeping areas.
This equipment should be installed in accordance with: CAN/ULC-S553, Standard for Installation of
Smoke Alarms.
Mobile Home Installation
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as
recommended above. In older mobile homes that are not well insulated compared to present stan-
dards, 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 10 cm (4”) and a maximum of 30.5 cm (12”) below the ceiling.
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 compared to the room air temperature, install the alarm on an inside wall.
CAN/ULC-S553 and NFPA 72 require smoke alarms be installed in each sleeping area.
WARNING: TEST YOUR ALARM OPERATION AFTER MOBILE HOME HAS BEEN IN
STORAGE OR UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.
