Are smoke detectors required to be hardwired?
Summary of Smoke Detector Article
What is better hardwired or battery smoke detectors
Hardwired smoke alarms are more dependable as they are connected on a power supply. Once the alarm sounds, they will not stop until turned off. In case of power interruptions, they have battery backups for continuous operation. Battery-powered smoke alarms depend solely on the batteries.
