Pit telephone system <ancillary equipment and safety instrumentation>
External phone call from the pit! A wireless phone system that allows voice calls within the coverage area of a phone base station.
We offer an "Underground Telephone System" suitable for communication in mines and work sites. Within the radio range of the telephone base station, our wireless telephone system allows for voice calls, enabling both internal and external calls from underground. We can also provide proposals that include fixed telephones within the facility. 【Features】 ■ Direct Inward Dialing (DID) function allows individual external calls to each terminal ■ Broadcasting of recorded audio sources and paging is possible through speakers installed in various locations ■ By connecting with metal lines, the base station/fixed telephone power is sourced from the exchange, eliminating the need for power underground ■ In the event of a power outage, calls can still be made using the emergency power supply of the exchange *For more details, please refer to the PDF document or feel free to contact us.
