Import Explosion-Proof Acoustic Light Alarm Bbj — Buy in wholesale FOB from Supplier in China

The Explosion-proof Acoustic Light Alarm BBJ is a dual-alert device designed for hazardous industrial environments where explosive gases or dust may be present. It combines a high-decibel acoustic signal with a rotating strobe light, certified to operate safely in Zone 1 and Zone 2 hazardous areas under IEC 60079-0 and IEC 60079-1 standards. The unit operates on 24V DC or 48V DC auxiliary power, with a sound output of 115 dB at 1 meter and a light intensity of 1000 cd, ensuring visibility and audibility in noisy, low-light conditions typical of coal mines and chemical plants.

The housing is constructed from die-cast aluminum with an epoxy powder coating, rated IP66 for dust and water resistance. Internal components are sealed against ignition sources, with flameproof enclosures meeting Ex d IIC T4 requirements. Typical industry variants include models with different mounting brackets, optional remote control interfaces, and compatibility with PLC systems via dry contact outputs. The device is not rated for continuous immersion or corrosive atmospheres beyond standard industrial humidity levels.
