11. GOOD SAFETY HABITS
The use of this product should not be seen as a substitute for basic safety precau-
tion in the prevention of FIRE.
There are situations where a smoke alarm may not be effective to protect against fire:
11.1 smoking in bed;
11.2 leaving children home alone;
11.3 cleaning with flammable liquids, such as petrol.
12. THE LIMITATIONS OF SMOKE ALARMS
12.1 Smoke alarms are devices that can provide early warning of possible devel-
oping fires at a reasonable cost.
12.2 Alarms have sensing limitations. Ionisation sensing alarm may detect
invisible fire particles (associated with fast flaming fires) sooner than
Photoelectric alarms. Photoelectric sensing alarm may detect visible fire
particles (associated with slow flaming fires) sooner than Ionisation alarms.
Home fires develop in different ways and are often unpredictable. Neither
type of alarm (photoelectric/ionisation) is always best and a given alarm may
not always provide warning of a fire.We strongly recommend that both
ionisation and photoelectric smoke alarms be installed to help insure maximum
detection of the various types of fires that can occur within the home.
12.3 Smoke alarms have certain limitations. For battery powered smoke alarms,
the battery must be in good condition and installed properly.
12.4 AC powered alarms will not operate if AC power has been cut off, such as by
an electrical fault, open fuse or circuit-breaker, or fire. However, the battery
back-up will activate the alarm if in good working order.
