If the sprinkler system cannot be started at the time of need, it may cause huge economic losses. The system needs to have high reliability. Therefore, in the design stage of sprinkler system, it is necessary to carry out reliability modeling and prediction to ensure that the system reliability can meet the requirements. In this paper, the design scheme of a building sprinkler system is analyzed in depth, and then a task reliability model considering maintenance strategy, stand-by period failure and task period failure is established, and the reliability is predicted to evaluate whether the design scheme of the system can meet the design needs.
