Two-pack of slim 10-year photoelectric smoke alarms provides reliable whole-home coverage with First Alert Precision Detection technology, delivering early warning of smoldering fires while reducing nuisance alarms from cooking. Each unit features a low-profile design that mounts close to the ceiling and runs on a sealed 10-year lithium battery, eliminating battery replacement and low-battery chirps for the life of the alarms.
