Someone else posted this elsewhere, but it's also relevant here. Statistics from the National Fire Protection Association support the idea that people disable their smoke detectors over nuisance alarms: Smoke alarm failures usually result from missing, disconnected, or dead batteries. When smoke alarms should have operated but did not do so, it was usually because batteries are missing, disconnected or dead. People are most likely to remove or disconnect batteries because of nuisance activations. Sometimes the chirping to warn of a low battery is interpreted as a nuisance alarm. http://www.nfpa.org/research/statistical-reports/fire-protection-systems/smoke-alarms-in-us-home-fires http://www.nfpa.org/research/statistical-reports/fire-protec...
