SMOKE DETECTOR (ALARM)
Fires, when detected at their initial
stages can easily be contained or extinguished before they
get out of hand. Most fires occur at night when people are
sleeping. A smoke detector can alert you when there is a
fire, in time to save your life. Smoke Detectors are most
suitable for offices and homes.
A Smoke Detector is a warning
device that detects smoke at the earliest stages of a fire.
HOW THEY WORK
Smoke alarms work by sensing rising smoke
from a fire and sounding an alarm.
There are two types of smoke detectors
– This contains a small, safe radiation chamber source that
is sensitive to free-burning fires with flames.
– It uses photoelectric bulb
that sends a beam of light and is more effective at
detecting slow-burning fires like overheated electrical
wiring. This type is less likely to go off accidentally or
when you are cooking.
Detectors are powered in two ways:
– These are the easiest to install. They require no outlets
or wiring connection; however, batteries must be replaced
approximately once a year.
ELECTRIC (MAINS) POWERED
– These are powered by electric supply and it solves the
problem of checking the battery. It can be done in two
ways. They can be plugged into any wall socket or can be
wired permanently into the electrical system of the
WHERE TO FIX A
Smoke rises, so the best
place to install is on the ceiling or high on an inside wall
just below the ceiling.
In a multi-level
air-conditioned structure, a detector is needed on each
level. On the first floor, it should be placed on the
ceiling at the base of the stairwell.
Detectors should be
installed close enough to the bedrooms so the alarm can be
heard when the door is closed.
If you are installing more
than one detector you may want to consider purchasing units
that can be inter-connected. That way when one unit detects
smoke, all the detectors will sound an alarm.
Remember not to install a
detector within 3ft (92cm) of an air-condition or fan that
might blow the smoke away.
HOW TO LOOK AFTER
YOUR SMOKE DETECTOR
Clean your detector regularly
as dirt may lead to its malfunction
Test your detector regularly.
Determine the proper method suggested for your model from
Replace batteries twice a
year. Establish dates for battery replacement.
A chirping sound at short
intervals indicates that the battery needs replacing.
All members of the household
should be aware of the alarm source.
A different member of the
family should test any time testing is done.
