Check the date
Every detector has a manufacture date on the back. Replace at 10 years regardless of testing.
Interconnection
When one alarm senses smoke, all alarms sound — critical in two-story homes and for sleeping children.
Photoelectric vs ionization
Photoelectric detects smoldering fires faster; dual-sensor or photoelectric is recommended for bedrooms.
Carbon monoxide
Add CO detectors near sleeping areas and on each level, especially with gas appliances or an attached garage.
