According to the National Fire Protection Agency (NFPA), smoke detectors are one of the "must have" safety devices that should be set up in every home. These devices should be hard-wired into the electrical system with a battery back-up in case the power is unsuccessful in the middle of the night.
NFPA further claims that by installing these devices on your buildings, you can reduce the risk of fire related accidents and deaths by almost 60%.You can check http://www.sydneylocalelectricians.com.au/ online to know more about Smoke Detectors.
However, there is a vicious circle. Just installing these devices is not enough to ensure the safety of your family. In order to protect your property and your precious ones these devices require maintenance to ensure their functionality.
Strategic placement: The correct placement of these devices can really help save lives. If you live in a multi-story building, smoke detectors should be installed on every level, inside the bedrooms, outside the sleeping quarters, and all the devices should be interlocked. When the devices are interlocked all will go off at the same time.
Do not place them too close to the fireplaces or kitchen area to avoid nuisance alarms. However, ensure that they are placed near windows, ceiling fans, bathrooms and heating appliances.
Periodic Check will always help: You should replace the batteries annually and test the device at least once a month to ensure that it is working properly. You should also replace the smoke detectors themselves every 8-10 years as they don't last forever.
