On a Sloping Ceiling
With a sloping or peaked ceiling install a Smoke Alarm within 600mm of the peak
or a Heat Alarm within 150mm of the peak (measured vertically). If this height is less
than 600mm for Smoke Alarms or 150mm for Heat Alarms the ceiling is regarded
as being flat
(see
Figure 4
).
Locations to avoid
DON’T place Smoke Alarms in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other rooms where the smoke
alarm may be triggered by steam, condensation, normal smoke or fumes. Keep at
least 6 metres away from sources of normal smoke/fumes.
• Locate away from very dusty or dirty areas as dust build-up in the chamber can impair
performance. It can also block the insect screen mesh and prevent smoke from
entering the smoke detector chamber.
