How Smoke Detectors Work

Smoke Detectors have been proven to save lives and reduce the damage caused by home fires.

The type of smoke detector you choose will depend on your individual needs. There are two main types:

• The optical detector works with a LED light in the unit. When smoke enters a chamber and interrupts the passage of light to the sensor, the alarm sounds.
• The ionization detector has a radioactive component that passes through a chamber creating a current between electrodes. Again when smoke enters the chamber, the current is interrupted and the alarm sounds.

The optical type are generally better for detecting slow, smouldering fires, whereas the ionization types are better for detecting smoke generated by flaming fires.

There are other types of smoke detectors available and also detectors and are stand-alone or that can be installed as part of an overall security system which can be monitored 24/7.

Governments have seen the value in smoke detectors for saving lives and reducing damage as a result of household fire, and smoke detectors are often mandatory in new dwellings, for very good reason. Most smoke detectors are priced within range of even the tightest budget.

Smoke Detectors are a cost effective way to provide safety and security for your family in your own home.
