Besides that, methods of probability calculations are briefly observed, the Author mentions about reference sources with verified failure rate data from Original Equipment Manufacture or certification agencies specialized in dependability issues of devices. Safety Requirements Specification of annunciator is analyzed too with key technical parameters. Considered approach can be applied to dangerous failure criteria of other electrotechnical installations which are integrated in Safety Instrumented Systems
