Hardwire Dual Photoelectric & Ion Sensor Smoke Alarm w/Battery Backup

Product Overview

Technology Detects Both Types of Fires

The First Alert Smoke and Fire Alarm comes equipped with two different sensors to provide an early warning. The ionization sensor detects flaming fires, such as grease fires or wastebasket fires, and the photoelectric sensor detects smoldering fires, such as when a lit cigarette ignites clothing or upholstery. Both sensors in the battery powered smoke alarm work together to provide comprehensive smoke and fire detection.

Smart Sensor Minimizes False Alarms

People often disable fire detectors when they go off due to cooking smoke or steam, even though that leaves themselves and their loved ones unprotected. Intelligent sensing technology in the First Alert Ultimate Protection, Battery Powered Smoke and Fire Alarm is designed to distinguish between real fires and nuisances, reducing false alarms significantly so there is never a need to disable the smoke alarm.

Battery-Powered Fire Detector Installs Easily

The battery-operated fire detector can be installed with no wires required. A low-battery indicator light and audible chirp lets you know it is time to change batteries. The battery compartment opens without the need to remove the smoke alarm from the mounting bracket, making battery replacements quick and easy.
