Smoke alarms with Ionization use a small amount of radioactive material to ionize air within the alarm. If smoke gets into the alarm, it disrupts the process of ionization and causes that the alarm alarm to go off. These kinds of smoke alarms are effective in detecting rapid burning fires and are generally less expensive in comparison to photoelectric fire alarms.

However, ionization smoke alarms are not as effective at deterring slow burning fires. They also are more susceptible to false alarms caused by cooking or steam, which can be frustrating for homeowners. Ionization smoke alarms are best utilized in areas where there are kitchen appliances that are not in use, such as bedrooms and hallways.

Photoelectric Smoke Alarms

Photoelectric smoke alarms employ the use of light beams that detects smoke. If smoke gets into the alarm it scatters light, which causes an alarm sound. Smoke alarms of this type are effective in detect slow burning fires, and are less susceptible to false alarms from cooking or steam.

But photoelectric smoke alarms aren’t as effective in detecting rapid flames. They’re also more expensive than ionization smoke alarms. Photoelectric smoke alarms should be utilized in places in which there are cooking appliances, like living rooms and kitchens.

Dual Sensor Smoke Alarms

Dual sensor smoke alarms combine both ionization and photoelectric sensors to provide the most complete fire detection. They can detect both quick, flaming flames and slow burning fires and are less susceptible to false alarms than photoelectric or ionization smoke alarms by themselves.

However, smoke detectors with dual sensors are typically more expensive than ionization or photoelectric smoke alarms alone. Dual sensor smoke alarms are best employed in areas where both fast, flaming fires and slow burning fires are feasible like bedrooms and living rooms.

Smart Smoke Alarms

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