Smoke Alarms with Ionization

Smoke alarms with Ionization use some radioactive substance to ionize air in the alarm. When smoke enters in the smoke alarms, it disrupts the process of ionization and causes an alarm sound to be heard. These kinds of smoke alarms are excellent at detecting quick flames, and they generally cost less as photoelectric alarms.

But, ionization smoke alarms are not as effective at deterring slow burning fires. They are also more prone to false alarms from steam or cooking, which can be frustrating for homeowners. Smoke alarms that ionize are best employed in areas with none of the cooking equipment, such as hallways and bedrooms.

Photoelectric Smoke Alarms

Photoelectric smoke alarms employ the use of light beams for detecting smoke. When smoke enters the alarm it scatters the lightand causes the alarm to sound. Smoke alarms of this type are effective in detecting slow, smoldering fires and are less vulnerable to false alarms caused by steam or cooking.

But, photoelectric smoke alarms aren’t as effective at detecting quick, flaming fires. They are also generally more expensive than ionization-based smoke alarms. Photoelectric smoke alarms should be employed in areas where there are cooking appliances, for example, kitchens and living spaces.

Two Sensor Smoke Alarms

Dual-sensor smoke alarms combine photoelectric and ionization sensors to provide the most comprehensive fire detection. They are effective in detecting both rapid, flaming fires as well as slow burning fires and are less prone to false alarms than ionization or photoelectric smoke alarms on their own.

However Dual sensor smoke alarms tend to be more expensive than either ionization or photoelectric smoke alarms alone. Dual sensor smoke alarms should be used for areas in which both fast burning fires, flames and slow burning fires are feasible, such as bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi networks and send out notifications to your smartphone or other device if they spot smoke or fire. They also can be integrated with other smart home devices such as smart thermostats as well as security devices.
