First Alert Photoelectric Smoke Detectors come equipped with a photoelectric sensor that reliably detects smoke produced by smoldering fires. Photoelectric sensors are optimized to detect larger smoke particles created by smoldering fires such as those caused by unextinguished cigarettes. First Alert Photoelectric Smoke Alarms are also excellent for distinguishing between real threats and smoke/vapor produced during showers, cooking and other everyday activities. Minimizing the number of false alarms activated, First Alert Photoelectric Smoke Detectors will help ensure that you’re alerted to actual threats.
First Alert Hardwired Photoelectric Smoke Alarms plug directly into you home's electrical system and come equipped with a backup battery that enhances overall peace of mind. Hardwired photoelectric smoke detectors can operate independently or be interconnected with other compatible hardwired smoke alarms. Battery operated photoelectric smoke alarms can be conveniently installed wherever smoke and fire protection are required. The First Alert Store also features an extended selection of combination alarms that implement photoelectric sensors. Combo detectors with this sensor are capable of offering dual protection from smoke and carbon monoxide in the surrounding area.
Where to Place Photoelectric Smoke Alarms: One in every bedroom, and at least one on every level of the home.
