SAT system enables the execution of quick, direct dispatcher's and telephone emergency - loud speaking communication with the utilization of subscribers' telephone exchanges of any type. It is adjusted to work in difficult industrial conditions, such as mining, petrochemical, chemical plants, and similar. It can be used in places with high acoustic levels, extensive humidity, salinity and dustiness, as well as in locations endangered by explosions of methane and other gases, fuel vapors, etc. (explosive groups I and IIB according to the standard PL_EN 50014).

The basic advantage of this system, if compared to previous solutions (TEDAR, STAR), is the application of disperse control systems what enables the full module flexibility. This feature allows the construction of individual systems with the capacities from a few ones to 192NN, with the option to be developed through netting of several systems.
Additionally, the system module structure has increased few times the system reliability, because any possible system failure within the scope of one module with OSA controller would not destabilize the work of the others. One from among OSA controllers at SAT rack is declared as the master controller.
SAT system may also cooperate with other devices - such as, for instance, methane-detecting, fire, telephone exchanges, visualization systems and other. These devices are linked to the outside RS485 main conduct through BUZ buffers of outside equipment or via Ethernet.
SAT system is equipped with four acoustic rails what enables the simultaneous work of four dispatchers. Additional computers, without conversation option, may be hooked up with the status of a watch post.

With all types of telephone exchanges.
