First Alert SA302B Battery Powered Smoke Alarm with Photoelectric & Ionization Sensors Review

The First Alert Smoke and Fire Alarm offers ultimate safety with dual photoelectric and ionization sensors. Ideal for kitchens and bedrooms; Ionization is more sensitive at detecting small particles, which tend to be produced in greater amounts by flaming fires. Photoelectric is more sensitive at detecting large particles, which tend to be produced in greater amounts by smoldering fires. Use your TV remote control to silence unwanted alarms and test with no programming necessary. A nuisance resistant smart alarm helps recognize the difference between non-threatening conditions and real emergencies. The microprocessor technology automatically runs a daily self-check test on every smoke alarm function to assure you that it is working properly. The low battery silence quiets low battery alert for up to eight hours without affecting alarm operation. Optional tamper-resistant pins to lock battery and unit in place.
