•
When mounting the alarm on the wall, use an inside wall with the top edge of the detection ele-
ment a minimum of 15cm (6”) and a maximum of 30cm (12”) below the ceiling, and at least 61cm
(2 feet) from any inside corner (see DIAGRAM A).
•
Install smoke alarms on sloped, peaked or cathedral ceilings at or within 0.9m (3ft) of the
highest point (measured horizontally). Smoke alarms in rooms with ceiling slopes greater than
0.3m in 2.4m (1 foot in 8 feet) horizontally shall be located on the high side of the room. A row
of detectors shall be spaced and located within 0.9m (3ft) of the peak of the ceiling measured
horizontally.(see DIAGRAM "C")
•
Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is
more than 9.1m (30 feet) long.
•
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 prevent 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 at 15cm (6”) and a maximum of 30cm (12”) below the ceiling,
•
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 30cm (12”) vertically down from the
highest point (see DIAGRAM "D").
