10 Year Combo Photoelectric Smoke & CO Alarm w/ Voice

The First Alert PRC710V Combination Photoelectric Smoke and Carbon Monoxide Alarm with 10-Year Battery and Voice and Location helps protect your home from two potentially deadly threats by providing up to a decade of uninterrupted monitoring. Equipped with dual sensors, this low-profile alarm detects smoke from slow-burning, smoldering fires. Half as thick as a standard alarm, this detector has a slim, contemporary design that mounts unobtrusively on a wall or ceiling. A built-in 10-year lithium-ion battery provides continuous power, with no need to ever worry about changing the battery during the lifetime of the alarm.

Photoelectric Sensor Warns of Smoldering Fires

The First Alert PRC710V 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/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.

Electrochemical Sensor Monitors CO Levels

The alarm also features an advanced electrochemical sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Carbon monoxide can’t be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of the home and in each sleeping room, you can help protect your family from the danger of carbon monoxide.

Built-In 10-Year Battery

The First Alert PRC710V 10-Year Photoelectric Smoke and Carbon Monoxide Alarm features a built-in 10-year lithium battery that provides continuous power for the life of the detector. An end-of-life timer lets you know when the device should be replaced.

Sleek, Low-Profile Design

Half as thick as a standard alarm, the First Alert PRC710V Photoelectric Smoke and Carbon Monoxide Alarm packs premium detection features into a sleek, compact unit. The ultra-thin design features a white finish that blends seamlessly with most home decor.

Battery-Powered Alarm Installs Easily

This battery-powered smoke and carbon monoxide detector requires no rewiring and no electrician to install. Simply mount it on a wall or ceiling using the versatile twist-lock mounting bracket. An end-of-life signal will notify you when the detector is nearing expiration.

Talking Alarm Indicates Location and Nature of Threat

The First Alert PRC710V Combination Smoke and Carbon Monoxide Alarm features a talking alarm that not only provides a verbal warning of the danger, but also tells you its location, so you can plan the safest possible escape. Easy to program and operate, the talking alarm allows you to choose between 11 pre-programmed home locations. Indicator lights on the face of the unit display the presence of smoke or carbon monoxide, while an 85-decibel siren provides a clear, loud warning upon detection.
