What if you have a big house and there’s a fire starting somewhere in the basement and you’re asleep in your bedroom on the third floor?Fortunately photoelectric smoke detectors can be interconnected, meaning if a smoke detector sets off in the basement, all smoke detectors in the residence would alarm. This is effective in alerting the entire family. Installation and wiring, however, requires supervision. As maintenance, make sure to vacuum your smoke detectors monthly and test them weekly by burning a small material so it could detect smoke. As convenient as it sounds, smoke and carbon dioxide detectors do not last forever. It is best to replace smoke detectors every 10 years. Like most devices, the store or company should allow a return policy and issue warranty when buying smoke detectors. Limited warranties range from 2 10 years and return policies are permissible up to 90 days. Smoke detectors must indicate that it has met Underwriters Laboratories UL Standard 217 and carbon dioxide detectors must meet UL Standard 2034. UL conducts certification training on every electrical appliance. Smoke detectors can only alert you if there’s fire.
