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 invisi-

ble fire particles (associated with fast flaming fires) sooner than Photo-elec-

tric alarms. Photo-electric 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 (photo-electric/ionisation) is always best and a given alarm may not al-

ways 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.
