KXH127 Mining Explosion proof and Intrinsic Safety Sound and Light Signal Device Underground Communication Alarm Device

Description :

  The KXH127 mining explosion-proof and intrinsic safety type sound and light signaler is a communication and alarm device designed specifically for harsh environments underground in coal mines. This equipment mainly solves the problem of poor information transmission caused by high underground noise and low light, and is suitable for typical working conditions such as mining faces and transportation tunnels. As an important component of the mine safety system, the KXH127 mining explosion-proof and intrinsic safety type sound and light signaler ensures that workers can clearly receive instructions or alarms in complex environments through high decibel sound and high brightness flashing, ensuring operational safety and efficiency.

  The KXH127 mining explosion-proof and intrinsic safety type sound and light signal strictly complies with the GB3836 series electrical equipment standards for explosive environments and has the Exd [ib] Mb explosion-proof mark. The shell is made of high-strength cast steel or aluminum alloy material, and the surface has undergone anti-corrosion treatment. The protection level usually reaches IP54 or above, and can withstand underground moisture, dust, and mechanical impact. Its electrical parameter design meets the requirements of intrinsic safety circuits, with a typical operating voltage of 127V AC and a signal output sound level of not less than 85dB. The effective line of sight of the optical signal is far, ensuring good identification in long-distance tunnels.

  When selecting, it is necessary to clarify that the KXH127 mining explosion-proof and intrinsic safety type sound and light signal is suitable for mining environments with gas and coal dust explosion hazards. If only ordinary industrial alarms are needed, non explosion proof sound and light alarms can be selected to reduce costs; But if it involves underground areas of coal mines, such equipment with dual explosion-proof certification must be selected. Compared with pure voice communication devices, the KXH127 mining explosion-proof and intrinsic safety type sound and light signaler has added visual warning function, which is more suitable for high noise environments; Compared with ordinary explosion-proof lamps, it has specific signal coding or linkage control functions, dedicated to indicating status or emergency alarms.

  When installing the KXH127 mining explosion-proof and intrinsic safety type sound and light signal, it should be fixed in a position that is easy to observe and hear, and it is strictly prohibited to open the cover for maintenance when it is live. In daily use, it is necessary to regularly check the sealing of the shell and the integrity of the introduction device to prevent explosion. It is recommended to test the sound and light function once a month to ensure clear sound and normal flashing. Common faults include the speaker being damp and silent, or the LED module being damaged. In this case, professional electricians should replace the internal intrinsic safety components in a safe area. It is strictly prohibited to dismantle the core circuit at will in the underground site to maintain the explosion-proof performance and service life of the equipment.
