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 metal 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.

Why Is My Smoke Alarm Beeping?

Smoke alarms can beep for to the following reasons:

  • Low Battery: This is the most common cause. Most smoke detectors use a chirping sound (usually a single beep every 30-60 seconds) to warn you that the batteries are running low and need to be replaced. Don't wait until the alarm is silent - replace the batteries right away to ensure your smoke alarm continues to function properly.
  • End of Life: Smoke alarms don't last forever. If your smoke detector is beeping constantly or in a different pattern than the low battery chirp, it may be nearing the end of its intended lifespan and should be replaced altogether.
Product Details
  1. Smoke particles of varying number and size are produced in all fires. For maximum protection, use both ionization and photoelectric sensing technologies. Ionization alarms are generally more sensitive to fast flaming fires and photoelectric alarms are generally more sensitive to smoldering fires.

Speaking dual hazard alarm

The units are easy to install and have a low profile. They are easy to program for location. The voice alert is loud and easy to understand. The alarm is loud as well. Really like that you don't have to change the battery annually.

In my city, there are very stringent features that a smoke/co detector needs to have. None of my local stores provided the correct features!

Excellent Product

I recently purchased 3 new PRC710C Combo Smoke & CO Alarm with Voice & Location Feature. All seem to be working great. Set up was a snap. The base was able to use the same holes from the previous detector. I also purchased a new PR710 for an area where co detection is not recommended. Now I am good for 10 Years without changing any batteries.
