Why can Carbon Monoxide Alarms sense low levels of Carbon Monxide Spillage?
In the early 1990’s Carbon Monoxide Alarms were programmed to detect the slightest trace of Carbon Monoxide Spillage which became a nuisance being that everyone who had an alarm was having “false alarms.” The threshold of these alarms was so sensitive that they would ring if someone was smoking a cigarette close to one. These alarms picked up the name “Nuisance Alarms” therefore, much investigation was put into Carbon Monoxide Alarms. Since the 1990’s, the standards of Carbon Monoxide Alarms have been loosened. An expert who spoke at the ISH-NA trade show in Boston, Rudy Leatherman, stated “that’s because the manufacturer’s are dumbing up the alarms. Therefore the standards for CO Alarms to activate have been raised. ” UL standard’s CO low level resistance threshold standard used to be no alarm: 15 ppm CO for 8 hours, which was considered to low due to all the “nuisance alarms” going off. Now, the standard has been changed to no alarm: 30 ppm, 30 days. Another expert who spoke at the I
