Kidde Safety

<h3>About Kidde Safety</h3><p><strong>Kidde Safety</strong> has been at the forefront of fire protection for more than a century. <a href="/7414-kidde-safety">Kidde</a> traces its roots to 1917, when Walter Kidde founded the Walter Kidde Company and produced the first integrated smoke detection and carbon dioxide extinguishing system for use on board ships. That spirit of pioneering innovation has never stopped — in 1924, the company introduced the first portable carbon dioxide fire extinguisher, and in 1925 it installed the first built-in industrial fire extinguishing system. Over the decades, Kidde has grown into one of America's largest manufacturers of smoke alarms and fire safety products, with a presence in homes and businesses around the globe.</p><h3>A Legacy of Industry Firsts</h3><p>Kidde's history reads like a timeline of fire safety milestones. In 2012, the brand introduced the Worry-Free line of smoke alarms featuring a 10-year sealed-in lithium battery, sparing homeowners the hassle of annual battery changes. The following year, Kidde became the first manufacturer to offer carbon monoxide alarms designed to last a full decade. By 2017, the company had released the P4010 Series alarms with 10-year sealed batteries and Wire-Free interconnect technology — meaning when one alarm sounds, all connected alarms sound simultaneously and mobile alerts are sent directly to a homeowner's phone. Today, Kidde is recognized as the <strong>#1 most installed fire safety brand in North America</strong>, a position earned through consistent innovation and an unwavering commitment to protecting families.</p><h3>A Complete Home Safety Lineup</h3><p>Kidde designs and develops a comprehensive range of products built around a single purpose: protecting people and property from fires and related hazards. The core lineup includes smoke alarms, carbon monoxide (CO) detectors, combination smoke and CO alarms, fire extinguishers, escape ladders, and indoor air quality monitors. Whether you need a straightforward battery-powered smoke alarm for a guest bedroom, a smart combination detector that integrates with your connected home, or a dry-chemical fire extinguisher rated for kitchen or garage use, Kidde offers a solution that meets residential and commercial code requirements.</p><ul><li><strong>Smoke Alarms:</strong> Battery-powered, hardwired, and smart-enabled models, including dual-sensor designs that combine ionization and photoelectric technology for earlier detection of both fast-flaming and slow-smoldering fires.</li><li><strong>Carbon Monoxide Detectors:</strong> Standalone CO alarms and combination smoke/CO units with low-level CO warning alerts, digital displays, and long-life sealed batteries — including models rated for 10-year maintenance-free operation.</li><li><strong>Fire Extinguishers:</strong> A wide range of residential and commercial extinguishers, from compact kitchen models to commercial-grade dry-chemical units designed to meet NFPA and building code standards.</li><li><strong>Escape Ladders &amp; Safety Accessories:</strong> Collapsible escape ladders for multi-story homes, key boxes, and mounting cabinets to complete a whole-home safety plan.</li><li><strong>Smart &amp; Connected Devices:</strong> Wi-Fi-enabled and interconnect-capable alarms compatible with voice assistants, offering remote monitoring and real-time alerts through the Kidde HomeSafe platform.</li></ul><h3>Built to Code, Trusted by Professionals</h3><p>Kidde products are built for reliability and compliance in accordance with UL, ETL, and NFPA standards, making them a go-to choice for contractors, property managers, and safety professionals as well as everyday homeowners. The brand's depth of product knowledge is backed by a robust Safety Hub of educational resources covering proper alarm placement, extinguisher selection, carbon monoxide awareness, and fire escape planning — because Kidde believes the most powerful safety tool is an informed household.</p>
