Smoke Alarm
A smoke alarm is a smoke detection device. Most
of them work by optical detection or by physical
process, while others use both methods to
increase their sensitivity. There are four types
of smoke alarms on the market ?
Ionisation Cheapest and very sensitive to small
amounts of smoke from fires produced from paper
or wood. They will detect these fires before the
smoke has the ability to become too thick. They
are less sensitive to slow burning fires which
give off larger quantities of smoke before
flaming occurs. They can also be a bit
over-sensitive in kitchens. ? Optical These are
more expensive but more effective at detecting
larger particles of smoke produced by
slow-burning fires. They are less sensitive to
fast flaming fires. Optical alarms can be
installed near kitchens, as they are less likely
than ionisation alarms to go off when toast is
burned. ? Combined Combinations of optical and
heat alarms in one unit to reduce false alarms
while increasing the speed of detection. Some
people find their alarms are frequently set off
when they are cooking. This is because a smoke
alarm installed inside the kitchen must be a heat
alarm and not a smoke alarm. ? Heat They detect
the increases in temperature from a fire and they
are insensitive to smoke. Because of that, they
can be installed in kitchens. They cover a
relatively small area of a room, so potentially
several heat alarms need to be installed in a
large kitchen. Test Your Alarm Monthly! Testing
your smoke alarm involves more than just testing
or changing the battery. Testing of a smoke alarm
goes far beyond just pushing the test button on
your smoke alarm. Else, you can schedule a
plumber for a complete smoke alarm safety
inspection and test.
