b Explosion-proof fire sound and light alarm, referred to as the alarm, is a non-coded alarm and is suitable for installation in areas containing IIB and II temperature groups. In other places with explosive gas environments, when an accident or fire or other emergency occurs at the production site, the control signal sent by the fire alarm controller activates the audible and visual alarm circuit, and sends out audible and visual alarm signals to complete the alarm purpose. The alarm can also be used in conjunction with the manual alarm button to achieve simple sound and light alarm purposes. The alarm can be used with fire alarm controllers from any manufacturer at home and abroad. The alarm uses ultra-bright luminous tubes, which are clearly visible, have the characteristics of stable operation, long service life and low power consumption. The product complies with the requirements of Part B Electrical Equipment for Explosive Gas Atmospheres, General Requirements, Part B Electrical Equipment for Explosive Gas Atmospheres, Flameproof Type, and Part B Electrical Equipment for Explosive Gas Atmospheres, Intrinsically Safe Type. It has passed the inspection by the state-designated inspection unit and obtained the explosion-proof certificate.
