Smoke alarms with Ionization use some radioactive material to ionize the air inside the alarm. If smoke gets into inside the detector, it interrupts the ionization process, causing an alarm sound to be heard. These types of smoke alarms are good at detecting fast flames, and they generally cost less in comparison to photoelectric fire alarms.

However, ionization smoke alarms aren’t as effective in deterring slow burning fires. They are also more vulnerable to false alarms caused by steam or cooking which can be a hassle for homeowners. Ionization smoke alarms should be used in areas where there are kitchen appliances that are not in use, for example, hallways and bedrooms.

Photoelectric Smoke Alarms

Photoelectric smoke alarms use an illuminating beam for detecting smoke. When smoke enters the alarm, it scatters light, which causes it to sound. These kinds of smoke alarms are effective in detect slow burning fires and are less prone to false alarms caused by cooking or steam.

However, smoke alarms that use photoelectric technology aren’t as effective at detecting fast burning fires. They’re also typically more expensive than ionization smoke alarms. Smoke alarms that are photoelectric can be employed in areas in which there are cooking appliances, such as kitchens and living spaces.

Dual Sensor Smoke Alarms

Dual-sensor smoke alarms blend both ionization and photoelectric sensors to provide the most comprehensive fire detection. They are good at detecting both fast, flaming fires and slow, smoldering flames, and are less prone to false alarms than ionization or photoelectric smoke alarms alone.

However, dual sensor smoke alarms tend to be more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensors are best utilized for areas in which both quick burning fires, flames and slow, smoldering fires can be a possibility like bedrooms and living spaces.
