Quell Photoelectric Hallway Smoke Alarm Escape Light

This smoke detector has a sealed battery and lasts 10 years, reducing the hassle that comes with traditional smoke alarms. A maintenance-free lithium back-up battery ensures the alarm won't require battery replacement for a decade, while a photoelectric sensor detects smouldering fires better than ionization sensors.
