But, ionization smoke alarms are not as effective at detect slow burning fires. They also are more susceptible to false alarms caused by cooking or steam which can be a hassle for homeowners. Ionization smoke alarms should be used in areas where there are none of the cooking equipment, such as bedrooms and hallways.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use the use of light beams to detect smoke. When smoke is detected in the alarm and scatters light, which causes an alarm sound. These types of smoke alarms are effective in detect slow burning fires and are less prone to false alarms caused by steam or cooking.

Smoke alarms that are photoelectric can be employed in areas where there are cooking appliances, like 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 fast, flaming fires and slow, smoldering flames, and are less susceptible to false alarms than photoelectric or ionization smoke alarms by themselves.

However, Dual sensor smoke alarms are typically more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms should be utilized for areas in which both rapid burning fires, flames and slow, smoldering fires can be a possibility like living rooms and bedrooms.

Smart Smoke Alarms
