Choosing the Best Smoke Detector


Keep your home safe from fires and other harm by installing smoke alarms, fire alarms and smoke detectors. Choose from hardwired models or smoke detectors with batteries that can help you and your family feel even more secure. Bulk-savings options allow you to install detectors in all the necessary spaces, like your kitchen, hallways and bedrooms.


There are two main types of smoke alarms to choose from: photoelectric smoke detectors and ionization smoke detectors. Photoelectric detectors react quicker to the smoke from smoldering fires, while ionization detectors react quicker to the smoke from a flaming fire.


Smart capabilities, like those found in Nest smoke detectors, add even more peace of mind if you’re frequently out of the home due to work or travel, allowing you to receive mobile alerts when smoke has been detected in your home. Voice-assistance features add even more convenience for managing your devices without having to grab a stool or ladder to access them.


Hardwired smoke detectors include extra safety features, like a battery backup, that add additional security in case the power goes out. Some models also include additional sensors, such as smoke carbon monoxide detector combos. Long-battery-life models help you get the most out of your detectors before having to replace the power supply.
