Môn Tiếng Anh Lớp 9 Smoke alarms in the home
Smoke alarms are now a standard feature in Australian homes and are required by the National
Building Code in any recently built properties. They are installed to detect the presence of
smoke and emit a clear sound to alert you in the event of fire to give you time to escape.
There are two principal types of smoke alarms. Ionization alarms are the cheapest and most
readily available smoke alarms. They are also very sensitive to ‘flaming fires’ – fires that burn
fiercely – and will detect them before the smoke gets too thick. However, photoelectric alarms
are more effective at detecting slow-burning fires. They are less likely to go off accidentally and
so are best for homes with one floor. For the best protection, you should install one of each.
Most battery-powered smoke alarms can be installed by the home owner and do not require
professional installation. For the installation of hard-wired smoke alarms, powered from the
mains electricity supply, however, you will need the services of a licensed professional. Smoke
alarms are usually most effective when located on the ceiling, near or in the middle of the room
or hall. Photoelectric smoke alarms in any quantity may be disposed of in domestic waste. If
you have fewer than ten ionization alarms to get rid of, you may put them in your domestic
waste. If you have more than ten to dispose of, you should contact your local council.
Your battery-powered smoke alarm will produce a short beep every 60 second to alert you
when the battery is running out and needs replacing. Nevertheless, it should be tested every
month to ensure that the battery and the alarm sounder are working. Note that the sensitivity
in all smoke alarms will reduce over time.
