Smoke alarms that use Ionization utilize some radioactive material to ionize the air inside the alarm. When smoke is introduced into in the smoke alarms, it disrupts the process of ionization and causes that the alarm alarm to go off. Smoke alarms of this type are good at detecting fast flames, and they generally are less costly as photoelectric alarms.

However, ionization smoke alarms are not as effective at detect slow burning fires. They also are more susceptible to false alarms due to steam or cooking, which can be frustrating for homeowners. Ionization smoke alarms should be employed in areas with no cooking appliances, for example, hallways and bedrooms.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use a beam of light that detects smoke. If smoke gets into the alarm and scatters the lightand causes it to sound. These kinds of smoke alarms are effective in finding slow, smoldering fires and are less vulnerable to false alarms due to cooking or steam.

However, smoke alarms that use photoelectric technology aren’t as effective at detecting quick, flaming fires. They’re also typically more expensive than ionization smoke alarms. Photoelectric smoke alarms should be employed in areas where there are cooking appliances, such as living rooms and kitchens.

Dual Smoke Alarms with Smoke Sensors

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

However dual sensor smoke alarms are generally more expensive than either ionization or photoelectric smoke alarms by themselves. Dual sensors are best used in areas where both quick flames, flaming fires as well as slow, smoldering fires are possible, such as bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi network and can send alerts to your phone or other device if they spot smoke or fire. They can also be integrated to other intelligent home devices like smart thermostats, and security alarms.
