A smoke detector, whether an ionisation or photoelectric model, is easy to install in your home and essential for the protection of you and your family.

How the Two Types of Smoke Alarms Work:

1. Ionisation smoke alarms detect particles of smoke as they pass through a chamber. They have a very minute amount of radioactive material that actually charges the atoms or ions.

2. Photoelectric smoke alarms have a dark chamber that refracts light. The matter goes into a blackened chamber, so if there is a refraction of light from a particle going into the chamber, it sets the alarm off. However, a smoke alarm of this kind can't differentiate between a particle of dust, a moisture droplet and a smoke particle.

Where to Place Your Smoke Alarm:

The critical thing about a smoke alarm is not the type but rather the position in your house. Each home is different but the ideal position to install a smoke alarm is in your hallway near the bedrooms. If you have more than one sleeping area, make sure that each sleeping area as a smoke alarm. Always avoid putting an alarm near the kitchen because a smoke detector can't tell the difference between smoke from a fire or cooking.

Can I install a smoke detector myself?

Smoke alarms are usually battery operated and specifically made for the do-it-yourself market, so home owners shouldn't have too much trouble installing them themselves. Paricularly as most brands have basic fittings and instructions to help you to install them on the ceiling.

How often do I need to change the battery and maintain my smoke detector?

To make sure a smoke alarm is always functioning properly, the battery needs to be changed regularly - twice a year is recommended. The easiest way to remember is to change them when daylight savings begins and ends.

On most smoke alarms there is also a test button that you can depress with a broom handle; if the battery is still working, the alarm will sound. It's also important to keep the alarm clean, as insects can sometimes build up around the detector head. Now and again, run a duster over the alarm or go over it with the dust attachment on the vacuum cleaner.

Stay safe in your home and protect your loved ones from house fires with a professionally installed home smoke detector.
