BGH Explosion proof Loudspeaker Telephone

Instructions for Using BGH Explosion proof Loudspeaker Intercom System
1. Overview
Explosion proof loudspeaker intercom system is designed for on-site scheduling of administrative telephone networks in factories and mining enterprises, especially for production scheduling in explosion-proof areas. It is a scheduling loudspeaker communication equipment with telephone self amplification function. At the same time, a more ideal automatic control method was adopted to automatically put the extended call telephone into sleep mode when no one is using it. The telephone adopts digital anti noise technology, which greatly improves the system's service life, anti noise ability, and reduces the failure rate. It is an ideal broadcasting and communication equipment for high noise environments and flammable and explosive places such as petroleum, chemical, dock, military, steel metallurgy, and mining ground operation areas. The explosion-proof performance of its explosion-proof products is designed and manufactured in accordance with the requirements of national standards GB3836.1, GBH3836.2, and GBH3836.4. They have passed the national designated explosion-proof electrical product quality inspection and obtained an explosion-proof certificate. The BGH-6 explosion-proof loudspeaker intercom system will be maintained at a lifetime cost under normal use due to its excellent quality.
2. Characteristics
2.1 No additional wiring is required, and the on-site telephone line can be directly used. The system wiring is simple, the cost is low, and it is easy to use.
