📋 Table of Contents
1What's the difference between ionization and photoelectric smoke detectors?
Ionization detectors are better at catching fast-flaming fires, while photoelectric ones excel at smoldering fires. Most homes benefit from dual-sensor models that detect both types, giving you complete coverage.
2Do I need battery-powered or hardwired smoke detectors?
Hardwired detectors are more reliable since they're connected to your home's power, but battery-powered ones are easier to install and work during power outages if batteries are fresh. Many people use hardwired detectors with battery backup for the best of both worlds.
3How often should I replace smoke detector batteries and the unit itself?
Replace batteries twice a year (often during daylight saving time changes) and test them monthly by pressing the test button. Replace the entire detector every 10 years, as sensors degrade over time and won't reliably catch smoke.
4What features are actually worth paying extra for?
Smart detectors with app notifications are valuable if you're away often, and interconnected models that alert all units when one triggers add safety in larger homes. Basic models work fine for most households, but these upgrades make sense if you want extra peace of mind.
5Where should I install smoke detectors in my home?
Place detectors in every bedroom, outside sleeping areas, and on each level of your home—they need to alert you while you sleep. Avoid kitchens and bathrooms where steam and cooking fumes cause false alarms, and keep them at least 3 meters from cooking appliances.
