Smoke alarms with Ionization use a small amount of radioactive material to ionize air in the alarm. When smoke is introduced into in the smoke alarms, it interrupts the ionization process, causing that the alarm alarm to go off. Smoke alarms of this type are excellent at detecting quick burning fires and generally cost less as photoelectric alarms.

However, smoke alarms that use ionization are not as effective at detect slow burning fires. They are also more vulnerable to false alarms caused by cooking or steam which can be a hassle for homeowners. Smoke alarms that ionize are best employed in areas with kitchen appliances that are not in use, like hallways and bedrooms.

Photoelectric Smoke Alarms

Photoelectric smoke alarms use an illuminating beam that detects smoke. When smoke enters the alarm and scatters the light, causing an alarm sound. Smoke alarms of this type are effective in finding slow, smoldering fires and are less prone to false alarms caused by cooking or steam.

But, photoelectric smoke alarms aren’t as effective in detecting rapid burning fires. They’re also more expensive than ionization alarms. Smoke alarms that are photoelectric can be utilized in places that have 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 complete fire detection. They are good at detecting both fast, flaming fires and slow, smoldering flames, and are less susceptible to false alarms than either photoelectric or ionization smoke alarms by themselves.

However Dual sensor smoke alarms tend to be more expensive than either ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms are best employed when both rapid burning fires, flames and slow, smoldering fires are possible for example, bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms connect to your home’s Wi-Fi network and send out notifications to your smartphone or any other device when they spot smoke or fire. They also can be integrated to other intelligent home devices like smart thermostats, as well as security devices.
