Frequently Asked Questions
What is the difference between photoelectric and ionization smoke detectors?
Photoelectric smoke detectors use a light sensor to detect smoke particles. They are generally more effective at detecting smoldering fires. Ionization smoke detectors use a small amount of radioactive material to detect microscopic particles. They are typically faster at detecting flaming fires. Many modern detectors combine both technologies for comprehensive protection.
How often should I test and replace my smoke detectors?
Test your smoke detectors monthly by pressing the test button. Replace batteries at least annually, or more frequently if the detector chirps to indicate low battery. Replace smoke detectors every 10 years, as the sensors degrade over time and they are usually labeled with a manufactured date.
What are the advantages of smart and wired smoke detectors?
Smart smoke detectors connect to your home's Wi-Fi network and send alerts to your smartphone, allowing you to monitor your home even when you're away. They can also provide more detailed information about the type of hazard. Wired smoke detectors are hardwired into your home's electrical system for continuous power and are often interconnected, so if one goes off, they all do.
