Smoke Alarms for Ionization

Ionization smoke alarms use some radioactive material to ionize the air in the alarm. When smoke is introduced into inside the detector, it interferes with the ionization process, causing the alarm to sound. These types of smoke alarms are effective in detecting rapid, flaming fires and are generally less expensive in comparison to photoelectric fire alarms.

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

Photoelectric Smoke Alarms

Photoelectric smoke alarms use the use of light beams that detects smoke. If smoke gets into the alarm and scatters the lightand causes the alarm to sound. These types of smoke alarms are good at finding slow, smoldering fires and are less vulnerable to false alarms caused by cooking or steam.

However, photoelectric smoke alarms aren’t as effective in detecting rapid, flaming fires. They’re also more expensive than ionization smoke alarms. Photoelectric smoke alarms are best used in areas in which there are cooking appliances, like living rooms and kitchens.

Dual Sensor Smoke Alarms

Dual-sensor smoke alarms blend photoelectric and ionization sensors to provide the most comprehensive fire detection. They are effective in detecting both fast, flaming fires and slow, smoldering flames, and are less vulnerable to false alarms than ionization or photoelectric smoke alarms by themselves.

However smoke detectors with dual sensors tend to be more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensor smoke alarms are best used when both rapid burning fires, flames and slow, smoldering fires are possible, such as bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms are connected to your home’s Wi-Fi network and will send out alerts to your phone or other devices if they detect fire or smoke. They also can be integrated to other intelligent home devices such as smart thermostats or security systems.
