For Wall Mounting:
If ceiling mounting is impractical, smoke alarms may
be mounted on a wall (if local ordinances permit),
provided that:
Wall mounting should only be considered where close
spaced beams or similar obstructions may preclude
ceiling mounting. It is considered to be the responsibility
of the installer or homeowner to determine if the
presence of asbestos in the ceiling material would make
ceiling mounting impractical.
• The top of the detection element is between 6 inches
and 12 inches below the ceiling.
• The bottom of the detection element is above the
level of any door openings.
Placement
For Ceiling Mounting:
Hot smoke rises and spreads out, so a central ceiling
position is the recommended location. The air is “dead”
and does not move in corners, therefore smoke alarms
must be mounted away from corners. Keep at least 12
inches from walls and corners. Additionally, mount the
unit at least 12 inches from any light fitting or decorative
object which might prevent smoke entering the smoke
alarm. Do not attach the detector to removable ceiling
panels.
