The following is a detailed introduction to the explosion-proof sound and light alarm: I. Overview Explosion-proof sound and light alarm (referred to as alarm) is a non-coding alarm, suitable for installation in explosive gas environments containing ⅡC (ⅡB) class T6 temperature group. When an accident or fire and other emergency occurs on the production site, the control signal sent by the fire alarm controller starts the sound and light alarm circuit and sends out the sound and light alarm signal to complete the alarm purpose. This product can also be used with manual alarm buttons to achieve simple acoustic and optical alarm purposes. 2. Technical parameters Explosion-proof mark: ExdⅡbT6 Working voltage: DC24V; AC220V (also available with AC127V option) Alarm current: DC24V ≤600mA Stroboscopic frequency: 60 times /min Sound intensity: 100-115dB Sound form: fire sound (can be designed as a police siren, ambulance sound according to user needs) Protection level: IP65 or no protection Operating environment: Temperature: -20℃-+50℃; Relative humidity: ≤95% no condensation; Atmospheric pressure: 80KPa-110KPa Inlet diameter: M22×1.5 (The quantity and size of inlet diameter can be designed and produced according to the needs of users) Weight: 1.4Kg Third, product characteristics The shell of the alarm is made of stainless steel shell or ZL102 aluminum alloy die-casting molding, the surface of high voltage electrostatic spray, with high strength and corrosion resistance. The lamp shell has strong impact resistance, adopts 360° clear visual ultra-bright LED light tube, and is equipped with super buzzer to ensure stable operation in harsh environment. The alarm has the characteristics of stable operation, long service life, low power consumption, and is not affected by pollutants and water. Fourth, installation and wiring Use M6 expansion screws or M6 screws to secure the explosion-proof shell of the fire sound and light alarm to the wall according to the site conditions. Connect the rubber and plastic cable with an outer diameter of φ6 ~ 8mm, and the explosion-proof inlet of the cable is M22×1.5 thread, which can be connected with the galvanized protective pipe or BNG15×700 explosion-proof flexible pipe, and can also be locked by explosion-proof sealing nuts. When connecting cables, connect the control cables to the + and - ends of the wiring terminals of the fire alarm according to the wiring diagram of the explosion-proof fire alarm. Pay attention to the explosion-proof surface do not include wire or other foreign matter. Wiring requirements: The insulation impedance between wires and between wires and the ground is greater than 20MΩ, and the resistance of a single line of the probe bus loop is less than 20Ω. V. Scope of application Explosion-proof sound and light alarm is suitable for flammable and explosive places such as petroleum, chemical industry, mines, tunnels, as well as public places such as families, schools, shopping malls. Once the detector detects an abnormal situation, such as fire, gas leakage, etc., it can respond quickly, emit a high-decibel alarm and a strong light flash to attract people's attention and take emergency measures. In short, explosion-proof sound and light alarm with its unique explosion-proof performance and efficient and intuitive alarm mode, become an important tool to guard every moment.
