Backup-power shoppers usually want a detector that stays dependable when the primary power path is interrupted. That makes this segment especially relevant for wired installs, remodels, and multi-room homes that cannot afford a blind spot during an outage.
Most of the strongest options here overlap with battery-backup smoke detectors and hardwired smoke detectors. If your setup is simpler and you do not need wiring, compare with battery-powered smoke detectors.
