Ionization smoke alarms are best employed in areas with kitchen appliances that are not in use, for example, bedrooms and hallways.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use a beam of light that detects smoke. When smoke is detected in the alarm it scatters the lightand causes it to sound. These kinds of smoke alarms are good at finding slow, smoldering fires and are less vulnerable to false alarms from steam or cooking.

But photoelectric smoke alarms are not as effective at detecting quick, flaming fires. They’re also typically more expensive than ionization-based smoke alarms. Photoelectric smoke alarms are best used in areas in which there are cooking appliances, such as living rooms and kitchens.

Dual Sensor Smoke Alarms

Smoke alarms with dual sensors combine both ionization and photoelectric sensors to offer the most complete fire detection. They are good at detecting both quick, flaming flames and slow, smoldering flames, and are less vulnerable to false alarms than either photoelectric or ionization smoke alarms on their own.

However smoke detectors with dual sensors are typically more expensive than either photoelectric or ionization smoke alarms alone. Dual sensor smoke alarms should be utilized for areas in which both fast, flaming fires and slow burning fires are possible like bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms connect to your home’s Wi-Fi networks and send out alerts to your smartphone or any other device when they spot smoke or fire. They are also able to be connected into other home smart appliances, for example, smart thermostats as well as security devices.
