Understand Features
Look for additional features like carbon monoxide detection. Some models combine smoke and carbon monoxide alarms. This gives you extra protection in one device.
What to look for
Type of Power Source
Smoke detectors can be battery-operated or hardwired. Battery-operated models are easy to install. You don’t need any wiring. Hardwired options connect directly to your home’s electrical system. They often have battery backups for outages.
Detection Technology
Different detectors use various technologies. Photoelectric smoke detectors sense smoke particles. They are good for smoldering fires. Ionization detectors respond faster to flaming fires. Consider what type of fire risk is common in your area.
