Sonny Saipale may not have expected to win any prizes during a recent sales contest, but when he won, he scored some 300 smoke detectors for the store to benefit fire departments and took home a bit of “gold” for himself. Kidde Fire Safety, a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. and a vendor of smoke detectors, recently sponsored a contest asking employees of The Home Depot throughout four states to sell fire suppression and alert systems. The region included Utah, Nevada, northern Arizona and most of California, Dylan Zecha, assistant manager of The Home Depot in west St. George said.
