Ionization Smoke Alarms

Smoke alarms with Ionization use only a tiny amount of radioactive material to ionize air within the alarm. If smoke gets into in the smoke alarms, it interrupts the ionization process, causing an alarm sound to be heard. These types of smoke alarms are good at detecting fast, flaming fires and are generally less expensive as photoelectric alarms.

However, smoke alarms that use ionization are not as effective at 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 should be used in areas with none of the cooking equipment, such as bedrooms and hallways.

Photoelectric Smoke Alarms

Photoelectric smoke alarms use the use of light beams for detecting smoke. When smoke is detected in the alarm, it scatters the lightand causes the alarm to sound. These kinds of smoke alarms are effective in detect slow burning fires, and are less susceptible to false alarms due to steam or cooking.

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

Two Sensor Smoke Alarms

Dual-sensor smoke alarms incorporate both ionization and photoelectric sensors to provide the most comprehensive fire detection. They are good at detecting both rapid, flaming fires as well as slow burning fires and are less susceptible to false alarms than either photoelectric or ionization smoke alarms by themselves.

However, smoke detectors with dual sensors are generally more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensors are best used for areas in which both fast flames, flaming fires as well as slow burning fires can be a possibility, such as bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms connect to your home’s Wi-Fi networks and send out alerts to your phone or other device if they detect smoke or fire. They also can be integrated with other smart home devices such as smart thermostats as well as security devices.

Smart smoke alarms are excellent in providing instant alerts, even when you’re not home. However, they are typically costlier than standard smoke alarms and require an internet connection that is reliable to work properly.
