Help protect your home with the First Alert PR700 Slim Battery-Operated Photoelectric Smoke Alarm. This low-profile smoke alarm uses an ultra-reliable photoelectric sensor to detect smoke from slow-burning, smoldering fires. Half as thick as a standard fire alarm, this detector has a slim, contemporary design that mounts unobtrusively on a wall or ceiling.
Photoelectric Sensor Warns of Smoldering Fires: The First Alert PR700 battery-operated alarm comes equipped with a photoelectric sensor to provide the earliest possible warning of fire. The sensor is optimized to detect larger smoke particles produced by smoldering fires, such as those caused by unextinguished cigarettes. It also distinguishes between real threats and smoke and vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. A patented smoke entry system helps ensure reliable detection by providing a direct air pathway to the sensor.
Sleek, Low-Profile Design: Half as thick as a standard alarm, the First Alert PR700 Photoelectric Smoke Alarm packs premium detection features into a sleek, compact detector. The ultra-thin design features a white finish that blends seamlessly with most home decor.
Battery-Powered Alarm Installs Easily: This battery-powered smoke detector requires no rewiring to install. Simply slide a 9-volt battery into the detector and mount the detector on a wall or ceiling using the versatile twist-lock mounting bracket. A low-battery light and chirp will let you know when the battery needs to be replaced, and an end-of-life warning will notify you when the smoke and fire detector is nearing expiration.
Alerts You to Danger: When smoke is detected, the smoke alarm sounds a loud 85-decibel siren that is designed to be easily heard. A single button allows you to silence alarms and test if the device is working.
