where possible, and not in a basement or furnace room.
2.
Install an alarm above the stairway and on every floor of the house.
3.
Smoke, heat and anything burning will spread horizontally after rising to the ceiling, so install the
alarm in the middle of the ceiling where possible. Ensure that the alarm is installed at the minimum
distance away from corner.
4.
If an alarm cannot be installed in the middle of a ceiling, install it at a distance of 20 inches (50 cm)
away from the corners of the room.
5.
If an alarm is installed onto a wall, a distance of 4-12 inches (10-30 cm) should be kept below the
ceiling.
6.
If the length of a room or hall is beyond 30 feet (900 cm), several alarms should be installed
in the same room.
7.
When the wall or ceiling is angled, the alarm needs to be installed within 3 feet (90 cm) of the
highest wall or ceiling point (measured horizontally) in the room.
8.
In multi-level houses or apartments, install at least one wireless smoke alarm on each level and
keep them installed in a straight vertical line (see diagram) with as few obstacles between each of
the interconnected alarms as possible to ensure optimal signal transmission.
Locations to Avoid:
1.
Near large metal surfaces and/or where there are lots of cables/wires that can cause interference.
2.
Near fluorescent lamps, amateur radios, electrical equipment, or other units that may transmit an
RF signal, as this electronic “noise”
can cause false alarms.
