ABSTRACT:
The method serves for automatic checking of the availability of technical equipment which is arranged in or at a building and executes at least one repeatable procedure, and comprises the following steps. There is determined at least one estimated value (NS(i,t)) for the frequency of the performance of the procedure for a first time period and/or second estimated value (NS(i,t+Δt)) for the frequency of the performance of the procedure for a second time period. A measured value Nm(i,t)) for the frequency of the performance of the procedure for the first time period is determined and the measured value is compared with at least one of the estimated values (NS(i,t), NS(i,t+Δt)). If the measured value (Nm(i,t)) is smaller by a predetermined amount (NS(i,t)−Nmin(i,t), ΔNs) than the respective estimated value (NS(i,t), NS(i,t+Δt)) at least one test of the technical equipment is carried out, in which test at least one reaction of the technical equipment is registered and compared with a target reaction, wherein in the case of availability of the technical equipment the reaction corresponds with the target reaction.
