A guide to smoke detectors

It is always important to maintain a safe home and protect your family against fire. As such, smoke detectors are a must-have.

Do you know what’s available in smoke detector technology, and have you taken the time to defend your home against fire? Check out our guide to fire detectors below.


Types of smoke detectors

When it comes to protecting your home against fir, there are a number of options. Discover how they work to protect you.

Heat detectors: The oldest form of fire-detection device is a heat detector. It functions with a detection element that activates when it reaches a fixed temperature or an extreme increase in temperature occurs. Aside from heat detectors, you have three options when it comes to smoke detectors: ionization, photoelectric, or a combination of the two.

Ionization smoke alarms: These smoke detectors are much more responsive to fast, raging fires and flames. They contain a small amount of radioactive material that passes between two electrically charged plates, which create an ionisation chamber. This configuration ionises the air and creates a current that flows between the plates. If smoke enters that space, it absorbs alpha particles and disturbs the ionisation process, which reduces the current and activates the alarm.

Photoelectric smoke alarms: These types of detectors typically respond better to smouldering fires. Photoelectric alarms work using a photoelectric sensor and a light source. As smoke enters the chamber and crosses the path of the light beam, light is scattered by the smoke particles, aiming it toward the sensor, which in turn triggers the alarm.

Smoke detector placement

Once you know what you need in terms of smoke detector technology, how do you determine how many detectors you need and where to place them? It is recommended that a combination of different sensors are used, and they should be installed:

  • inside every bedroom,
  • outside each sleeping area, and
  • on each level of the home.

Through combining various types of detectors and ensuring they are plenty installed in your home, you can rest easy knowing your home is as safe and protected as can be.
