Smoke alarms of this type are effective in detecting rapid, flaming fires and are generally less expensive as photoelectric alarms.

But, ionization smoke alarms aren’t as effective at detecting slow, smoldering fires. They are also more vulnerable to false alarms caused by cooking or steam and can cause a lot of frustration for homeowners. Smoke alarms that ionize are best employed in areas with none of the cooking equipment, for example, hallways and bedrooms.

Photoelectric Smoke Alarms

Photoelectric smoke alarms employ the use of light beams for detecting smoke. If smoke gets into the alarm and scatters the light, causing the alarm to sound. These kinds of smoke alarms are effective in detecting slow, smoldering fires and are less vulnerable to false alarms from steam or cooking.

However, photoelectric smoke alarms are not as effective at detecting quick burning fires. They’re also typically more expensive than ionization-based smoke alarms. Smoke alarms that are photoelectric can be employed in areas where there are cooking appliances, such as kitchens and living rooms.

Dual Smoke Alarms with Smoke Sensors

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

However Dual sensor smoke alarms are generally more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensors are best employed for areas in which both fast burning fires, flames and slow, smoldering fires can be a possibility like bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms are connected to your home’s Wi-Fi network and can send notifications to your smartphone or any other device when they detect fire or smoke. They are also able to be connected with other smart home devices, for example, smart thermostats as well as security devices.
