About this item

• Photoelectric sensor technology senses visible fire particles, associated with smoldering fires
• Smoke alarm operates on a 120V wired power source with a 9-Volt alkaline battery backup (included)
• An 85-decibel alarm sounds & a red LED indicates the smoke detector is sensing smoke or fire
• Test-Hush button makes it easy to test the smoke detector and silence false alarms that occur from cooking or shower steam
• UL listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim). Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that replacement is needed.
