Ionization smoke alarms use only a tiny amount of radioactive substance to ionize air within the alarm. If smoke gets into the alarm, it disrupts the process of ionization, which causes that the alarm alarm to go off. Smoke alarms of this type are effective in detecting rapid flames, and they are generally less expensive than photoelectric smoke alarms.

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

Photoelectric Smoke Alarms

Photoelectric smoke alarms use the use of light beams to detect smoke. When smoke enters the alarm it scatters light, which causes the alarm to sound. These types of smoke alarms are excellent at finding slow, smoldering fires and are less prone to false alarms from cooking or steam.

However, smoke alarms that use photoelectric technology aren’t as effective in detecting rapid flames. They are also generally more expensive than ionization alarms. Photoelectric smoke alarms are best used in areas where there are cooking appliances, such as kitchens and living rooms.

Dual Sensor Smoke Alarms

Smoke alarms with dual sensors blend photoelectric and ionization sensors to offer the most comprehensive fire detection. They can detect both rapid, flaming fires as well as slow, smoldering fires, and are less susceptible to false alarms than either ionization or photoelectric smoke alarms alone.

However Dual sensor smoke alarms are generally more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms are best used when both rapid, flaming fires and slow burning fires are possible, such as living rooms and bedrooms.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi network and send out alerts to your smartphone or any other device when they spot smoke or fire. They are also able to be connected into other home smart devices such as smart thermostats or security systems.
