3. Locations to be Avoided
(Smoke Alarms)
• In the garage. Products of combustion are present when you start your car. Only a Heat
Alarm is suitable in such locations
• In front of forced air supply ducts used for heating and air conditioning, near ceiling fans, or
other high air flow areas.
• Less than 10cm (4”) from the peak of an ‘A’ frame type ceiling.
• In an area where the temperature may fall below 0°C or rise above 40°C. Such as garages
and unfinished attics; this should also include electrical boxes exposed to these environ-
ments..
• In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
• In very humid areas. Moisture or steam can cause nuisance alarms.
• In areas where the Relative Humidity (RH) is above 93%.
• Near fluorescent lights or CFL lamps.. Electronic “noise” may cause nuisance alarms.
• In insect infested areas

kitchen,the door to a bathroom containing a tub or shower, ceiling or whole house ventilat-
ing fans orother high air flow areas..
• Kitchens: Normal cooking may cause nuisance alarms. Only Heat Alarms are suitable for
use in Kitchens; they should also be fitted in integral garages.
• Smoke alarms are not to be used with detector guards unless the combination (alarm and-
guard) has been evaluated and found suitable for that purpose.

lation.
