Benefits of a Dual Sensor Device [re-post]

What are dual sensors? In smoke alarms, these systems combine ionization and photoelectric smoke detection so that your home, business, or other buildings are protected from different types of fires. Haven’t heard of these terms before?

Here’s a quick rundown of what we’re talking about:

  • Ionization – Best at detecting fast-flaming fires: cooking fires, fires fueled by paper, and flammable liquid fires. These smoke sensors contain americium-241 in an ionization chamber. When even a small amount of smoke enters the ionization chamber, it disrupts the electric current passing through, and triggers the alarm.
  • Photoelectric – Best at responding to fires at their early, smoldering stage, before there are heavy flames. Photoelectric sensors contain a light source and a light-sensitive electric sensor (ie. photoelectric). Light misses the sensor under normal conditions but, during the early stages of a fire, smoke entering the chamber will scatter the light and sound the alarm.

Dual Sensor Smoke Detectors combine both these methods of detecting fires, keeping you safe from both slow, smoldering fires and quickly burning flash-fires. These combination alarms increase the chance that both flash fires and slowly burning, smoldering fires will be discovered as quickly as possible.

Ionization and photoelectric sensors work separately, filling the gaps so that your home is protected from different types of fire situations. Halo is a dual sensor smoke detector and then some!

As the safest, smartest smoke alarm ever created, Halo uses both ionization and photoelectric sensors to detect smoke, and it’s the first alarm in the industry to add carbon monoxide detection, and a weather radio to deliver severe weather warnings. All these benefits combined allow Halo to offer the most comprehensive protection of your family, home or business. It’s a dual sensor smoke alarm and so much more!
