Intrinsically Safe Telephone Signaler JANTAR 2

Application

Telephone Signaler JANTAR 2 is an intrinsically safe device designed for operation in particularly harsh and hazardous environments. Its high durability, IP67 protection rating, and intrinsic safety certifications make it an excellent choice for the mining industry and any location exposed to the risk of dust or gas explosions. Furthermore, its wide range of features and solutions facilitate everyday work while enhancing employee safety.

The JANTAR 2 intrinsically safe telephone signaler is compatible with all telephone exchanges and therefore it can be connected directly to a standard telephone line or via tele-transmission isolating systems (so-called intrinsic safety barriers). No additional external power supply is required. Full functionality of the JANTAR 2 – including remote telephone control – is available in cooperation with the HETMAN loud-speaking dispatcher broadcasting system.
