Why First Alert?

A legacy of firsts: First Alert was the first to release a battery-powered smoke detector that received a UL listing, the first to go to the retail market with a battery-operated smoke alarm and the first to develop a dual photoelectric/ionization alarm. Today, First Alert has introduced new Precision Detection smoke alarm technology to reduce nuisance alarms and detect smoke from synthetic materials to help provide an early warning.

For decades, First Alert has donated smoke and carbon monoxide alarms, as well as fire extinguishers, to local fire departments and nonprofits to help equip their communities across the country. First Alert and Lowe’s stores nationwide also join forces during Fire Prevention Month in October to raise fire safety awareness through educational store events focused on fire safety.

Your First Line of Defense Is First Alert

Lowe’s carries the First Alert products you need to help keep your family safe and protected during emergency situations, from First Alert smoke detectors and First Alert carbon monoxide alarms to fire extinguishers and fire escape ladders.

Which Products Do I Need?

Home safety can be a confusing montage of products and prices. That’s why Lowe’s carries a full suite of First Alert products to ensure you’re able to protect all points in your home affordably.

First Alert smoke alarms are designed to alert you and your family to the presence of smoke in your home.
Carbon monoxide (CO) alarms alert you to unwanted and potentially deadly levels of CO. Unlike smoke, carbon monoxide is a colorless, odorless, tasteless gas, which makes a detection device essential for the health and safety of people and pets in the home.
First Alert combination smoke and carbon monoxide alarms offer double protection in a single device.

All smoke alarms and First Alert carbon monoxide detectors can be either battery operated or hard-wired into your home’s electrical system. Both types of detectors offer trusted and reliable home protection. Your decision is based solely on preference.

Taking Action During an Emergency

It’s important to have a plan in place to protect your home and family. Talk to every home member and practice your plan to ensure everyone understands the appropriate actions to take to get to your designated meeting place.

First Alert fire extinguishers help you put out small fires in or around the home. Base the type of extinguisher you buy on the placement of the unit. For example, you may want a reloadable extinguisher in the kitchen and a heavy-duty fire extinguisher in the garage. Wall mounts are also available to ensure you’re able to access your unit quickly during a fire.
First Alert fire escape ladders are essential for any room without easy access to the ground, such as second- and third-story windows or living rooms positioned over a deep crawl space or basement. Easily stored under a bed or in a closet, these essentials can help members of your household exit the home if footpaths are blocked by fire.

First Alert offers a broad selection of products to help protect your home and family in case of emergency. For help with smoke and carbon monoxide detector installation, our how-to instructions offer step-by-step details.
