Packaged items of equipment (compressors, diesel engines, electricity generators, etc) are fitted with local vendor supplied instrumentation. When equipment malfunctions a multivariable signal (UA) is sent to the control room. The fire and gas detection system comprises local sensors to detect the presence of gas, smoke or fire. These initiate ...
