JDJL-2 explosion-proof fire alarm bell (abbreviated as alarm bell) is a non-coding alarm bell. It is suitable for installing in explosive gas environment with T6 temperature group of level II C (or II B). When an accident or fire occurs at the production site, the control signal sent by the fire alarm controller starts the alarm circuit and sends out sound alarm signal to complete the purpose of alarm. This product can also be used with manual alarm buttons to achieve simple sound alarm purposes. The alarm bell can be used in conjunction with the fire alarm controller of any manufacturer. The alarm bell has reasonable structure, beautiful appearance, reliable performance and convenient installation. It is a fire alarm device with high reliability and strong anti-interference ability. This product meets the requirements of GB3836.1-2000 "Electrical equipment for explosive gas environment Part 1: General requirements", "GB3836.2-2000", "Electrical equipment for explosive gas environment Part 2: Flameproof"d";". The inspection unit designated by the state has passed the inspection and obtained the explosion-proof qualification certificate. Installation: M6 screw is used to fix the alarm bell on the wall through the installation claw of the alarm bell (the inlet must be facing up). Cable introduction device: The sealing nut is used to press the sealing ring structure tightly. It can be widely used in petrochemical industry, oil fields, oil depots and liquids, gas station, coal mine, environmental protection and other departments.
