POSITIONING
Ionisation type smoke alarms are generally
more effective at detecting fast, flaming fires
which consume combustable materials rapidly
and spread fire quickly.
Examples fast flaming fires = Ignited paper,
flaming curtains and oil fires
Optical (Toast Proof) smoke alarms
are less
prone to false alarms from cooking fumes, are
therefore suitable for locations near kitchens.
However optical smoke alarms are more
susceptible to nuisance alarms from steam and
should not be located too close to bathrooms
and showers.
Examples of slow smouldering fires = cigarette
on furniture and bedding, overheating
electrical cables.
It is recommended that your Zeta smoke
alarm is NOT to be fitted in the following
locations:
• Bathrooms, shower-rooms, and other very
damp or humid areas, where the moisture
can cause unwanted alarms.
• Kitchens. Kitchens should be protected
with self-contained Heat Alarms, as the
combustion particles from cooking in
kitchens will result in unwanted alarms and
permanent contamination of the smoke
alarm’s sensor.
• In areas where excessive dust or dirt could
contaminate the sensing chamber, making
it over sensitive or impairing smoke entry.
• In areas where the ambient temperature
is not controlled and may regularly drift
below 4°C (40°F) or above 38°C (100°F)
e.g. unheated buildings, open attic
spaces.
• Very dirty, dusty or greasy areas.
• In very draughty areas, such as close to
ceiling fans or fresh air vents. Draughts can
blow smoke away from the alarm.
• In insect infested areas. Insects can
clog openings to the sensing chamber,
preventing smoke entry or causing
unwanted alarms.
• Within 30cm (12”) of a fluorescent light
fitting which emits electrical ‘noise’ that can
prevent correct alarm operation.
• In wall positions that are more than 30cm
(12”) away from the ceiling (see ‘How to
install your smoke alarm’).
• In ‘dead air’ spaces (see following
diagram).
• Within 30cm (12”) of light fittings or other
ceiling based obstructions.
WARNING:
Prolonged exposure to
temperatures outside those stated above
will reduce product life.
