Application at sensitive sites
MONOTOWNS, HAZARDOUS PRODUCTION FACILITIES AND ENTERPRISES
In case of failure of traditional wire systems of information transmission or difficulty of their installation
In case of abnormal situations at hazardous production facilities or sensitive sites, it is often impossible to warn all employees and population about danger and required precautions. The situation is worsened by the fact that the area of the territory of production facility or site can be several tens of square kilometers, and conventional warning equipment has insufficient capacity or is economically unprofitable as many audio radiators and kilometers of wire for their switching will be required. Therewith risk of failure of the system under conditions of emergency many-fold increased due to a large number of components. VSB long-range loudspeaking equipment can cover larger territories, as compared to conventional equipment, therewith number of required equipment is much lower.
