Scope

This standard specifies the product classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of the host of mine-used explosion-proof and intrinsically safe audible and visual language alarm devices. This standard applies to the host of mine-used explosion-proof and intrinsically safe audible and visual language alarm devices (hereinafter referred to as the host). Note: This mine-used explosion-proof and intrinsically safe audible and visual language alarm device host is mainly used in underground car yards and electromechanical rooms of coal mines, central substations, large-scale transportation corridors, pump rooms, and other places. It also provides the necessary DC power to various connected sensors, and issues voice and text alerts after receiving sensor signals.
