Websmoke detector, device used to warn occupants of a building of the presence of a fire before it reaches a rapidly spreading stage and inhibits escape or attempts to extinguish it. On sensing smoke the detectors emit a loud, high-pitched alarm tone, usually warbling or intermittent, and usually accompanied by a flashing light. There are two types of smoke …
WebIonization smoke detectors are banned because they are slow to detect smoldering fires and are prone to false alarms. On top of this, they contain radioactive material Americium 241, which is safe for humans but poses environmental issues with disposal and storage.
