Kidde 20SD10 Smoke Detector 5 in 10 Year Dc Round

Product Description

The KIDDE 20SD10 is a DC-powered smoke detector designed for residential and light commercial fire detection applications. Operating on a sealed 10-year battery, this round unit eliminates the need for frequent battery replacements and reduces ongoing maintenance demands. At 5 inches in diameter, it fits standard ceiling and wall mounting locations without modification. The 20SD10 is intended for installation by licensed electricians or fire alarm technicians working in compliance with NFPA 72 and applicable local fire codes. Its sealed long-life power source makes it well suited for retrofit and new-construction scenarios where low-maintenance detection is a priority.

This smoke detector is appropriate for residential bedrooms, hallways, living areas, and light commercial spaces requiring point-type smoke detection. The DC battery-powered design allows installation in locations where no AC wiring is present, making it a practical choice for renovation projects, rental units, and remote rooms. The round form factor and compact 5-inch diameter integrate cleanly with standard junction box footprints and existing detector mounting plates in many common installations.

Installation Notes

Installation should be performed by a licensed electrician or qualified fire alarm technician in accordance with NFPA 72 and all applicable local fire codes. Power down or confirm battery isolation before servicing any adjacent wired detection devices. Mount on ceilings or high on walls per the placement guidelines in NFPA 72 to ensure effective smoke detection coverage. Do not paint over the detector housing or cover sensing vents, as this will impair detection performance.
