Scope

Main technical content: Smoke detectors use photoelectric smoke detection or ion smoke detection technology to monitor the concentration of smoke to prevent fires. They can issue alarms directly after detecting fires in the early stage, reminding on-site personnel to deal with the situation promptly. The popularity of smoke detectors in old residential buildings, schools, dormitories, shops and other places in China is relatively low. With the development of urbanization in China and the continuous improvement of citizens' fire safety awareness, the demand for smoke detectors will become increasingly large and the requirements will also become higher. Based on the basic functional requirements proposed in Chapter 4 "General Requirements" of GB 20517-2006 for stand-alone smoke detectors, this standard adds water mist interference tests and dust interference tests, proposes high anti-interference and low false alarm rates for smoke detectors against non-fire interference smoke, and improves the accuracy of fire detection and alarm in water mist and dust environments widely existing in daily life and production, ensuring the safety of people's lives and property.
