- Required on every level, inside every bedroom, and outside each sleeping area
- Hardwired, interconnected smoke detectors are required in new construction
- Recommended replacement is every 10 years to keep smoke detection reliable
- Ionization sensors respond faster to flames; photoelectric to smoldering fires
- Battery backup is required on hardwired units to cover any power outage
