Ionization smoke alarms use some radioactive substance to ionize air in the alarm. When smoke enters the alarm, it disrupts the process of ionization, which causes that the alarm alarm to go off. Smoke alarms of this type are excellent at detecting quick burning fires and are generally less expensive as photoelectric alarms.

However, smoke alarms that use ionization aren’t as effective in detect slow burning fires. They also are more susceptible to false alarms from cooking or steam, which can be frustrating for homeowners. Ionization smoke alarms are best used in areas where there are kitchen appliances that are not in use, like hallways and bedrooms.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use the use of light beams to detect smoke. When smoke enters the alarm and scatters the light, causing the alarm to sound. These kinds of smoke alarms are effective in finding slow, smoldering fires and are less prone to false alarms from cooking or steam.

However, photoelectric smoke alarms are not as effective in detecting rapid flames. They’re also more expensive than ionization-based smoke alarms. Photoelectric smoke alarms should be used in areas in which there are cooking appliances, such as living rooms and kitchens.

Two Sensor Smoke Alarms

Smoke alarms with dual sensors combine both ionization and photoelectric sensors to offer the most complete fire detection. They can detect both quick, flaming flames and slow burning fires and are less prone to false alarms than photoelectric or ionization smoke alarms by themselves.

However, Dual sensor smoke alarms are generally more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensors are best used when both fast, flaming fires and slow, smoldering fires can be a possibility for example, bedrooms and living rooms.

Smart Smoke Alarms
