Retrofitting a complex, safety-critical PA system for periodic testing

摘要：

　　This paper describes considerations and the implementation of retrofitting a fully-automated procedure, for testing a public address system, into a safety-critical environment (a nuclear power plant).There are over 4000 loudspeakers, about 200 amplifiers as well as various alarm-signal generators that need to be tested every day within a few minutes.Additionally, all command room microphones are checked using a semi-automated procedure.The procedures were designed and configured to not only reliably detect single defective components, but also to not produce any false alarms.
