Smoke alarms with Ionization use a small amount of radioactive material to ionize the air in the alarm.

Smoke alarms of this type are good at detecting fast, flaming fires and generally cost less as photoelectric alarms.

But, ionization smoke alarms aren’t as effective at detecting slow, smoldering fires. They are also more vulnerable to false alarms due to steam or cooking and can cause a lot of frustration for homeowners. Ionization smoke alarms should be used in areas where there are no cooking appliances, such as bedrooms and hallways.

Photoelectric Smoke Alarms

Photoelectric smoke alarms use an illuminating beam to detect smoke. When smoke is detected in the alarm and scatters the light, causing an alarm sound. These types of smoke alarms are good at detect slow burning fires, and are less susceptible to false alarms from steam or cooking.

However, photoelectric smoke alarms aren’t as effective at detecting quick burning fires. They’re also more expensive than ionization-based smoke alarms. Smoke alarms that are photoelectric can be used in areas that have cooking appliances, like kitchens and living spaces.

Two Sensor Smoke Alarms

Dual-sensor smoke alarms combine both ionization and photoelectric sensors to provide the most complete fire detection. They are good at detecting both quick, flaming flames and slow, smoldering fires, and are less vulnerable to false alarms than either ionization or photoelectric smoke alarms on their own.

However, dual sensor smoke alarms tend to be more expensive than photoelectric or ionization smoke alarms on their own. Dual sensor smoke alarms are best utilized for areas in which both quick burning fires, flames and slow burning fires can be a possibility, such as bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi networks and send out alerts to your phone or other devices if they spot smoke or fire. They are also able to be connected to other intelligent home appliances, like smart thermostats, and security alarms.
