Becke Industrial Telephone EX-BT27 is a dedicated communication terminal designed for harsh environments and professional scenarios including industrial production, mining, tunneling, chemical engineering, energy, and rail transit. Unlike civilian telephones oriented toward portability and consumer-grade use, it boasts core features of high reliability, strong environmental adaptability, and professionalized functions. It can operate stably under special working conditions such as high temperature, high humidity, dust, strong electromagnetic interference, and flammable & explosive environments, serving as a key device for emergency communication and daily dispatching in industrial settings.
Stable operation under special conditions including high temperature, high humidity, dust, strong electromagnetic interference, and flammable & explosive environments.
•Made of composite new materials with integral molding, featuring a concise, elegant, practical and aesthetic design. •Waterproof and dustproof, no waterproof cover required. •Resistant to heavy impact and knocks, with wide temp tolerance, flame-retardant and superior insulation.
Compatible with mainstream IPPBX and network dispatching platforms on the market.
One-touch emergency direct dial to the command center with priority line seizure; synchronous zone group calls and mass broadcasts; high-sensitivity noise-canceling microphone plus high-power speaker ensure clear calls in machinery noise environments, with voice amplification support.
The waterproof telephone adopts a multi-level hybrid power supply architecture, fully adapting to power conditions in different deployment environments.
Industrial telephones (mostly SIP-type) are deployed at regular intervals in tunnels and interconnected with tunnel FM emergency broadcast systems. In the event of an emergency, on-site personnel can initiate emergency calls via the telephones, and the command center can directly issue dispatching instructions through the telephone terminals.
Mining industrial telephones feature waterproof, shockproof and explosion-proof performance. Connected to the underground dispatching system, they enable two-way communication between the surface and underground, and serve as an emergency rescue channel in case of accidents such as water inrush and collapse.
In hydropower stations, wind farms, substations and other sites, industrial telephones are used for equipment inspection, fault reporting and emergency dispatching, and are resistant to strong electromagnetic interference and harsh outdoor weather.
Explosion-proof industrial telephones are deployed in production workshops, tank farms and loading/unloading areas to ensure safe communication in flammable and explosive environments, and support interconnection with the park's emergency command platform.
