SENSOR TECHNOLOGY
There are two main types of smoke alarm. The
ZD-SI-601 Standard Smoke Alarm uses an
ionisation type sensor to detect the presence
of smoke. Ionisation type smoke alarms are
generally more effective at detecting fast,
flaming fires which consume combustible
materials rapidly and spread fire quickly. The
ZD-SO-601 Toast Proof Smoke Alarm uses an
optical (photoelectric) type sensor which is
more effective at detecting slow burning fires,
which can smoulder for hours before bursting
into flames.
TOAST PROOF =
less sensitive to cooking
fumes. (Optical alarms are less prone to
nuisance alarms due to cooking fumes.)
For maximum protection, use both types of
smoke alarms on each level of your home
