STG system
Local Intrinsically Safe Telephony and Loudspeaking Connection STG
Application
Application
STG system has been constructed with the idea of utilizing it as: a local shaft telephone connection system both in the intrinsically safe and regular version or a local telephone connection system for processing plants, hydraulic filling, and other applications, where a local loudspeaking telephone connection is necessary, as well as sending and receiving two-stage information (on /off).
This system enables the realization of automatic telephone connection what makes possible the fast flow of information between the plant personnel and the elevator machinist or a local dispatcher (after pressing the button DYSP or ALARM), and sending information and orders between the plant employees during the regular mine exploitation.
