Wireless 315MHz smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and visual alarm from the detector itself. Widely used in home, factory, school, shop, offices, villas, residential areas, corridors, basements, penthouses or other confined rooms.
