Abstract

The module is in the form of a plate (10) fitted with a number of conductors (17, 19, 22) respectively connected to a certain number of terminals (12, 14) forming part of connections mounted on two opposite edges of the plate. Each plate (10) is fitted with, during manufacture, lighting (18) loudspeakers (21), and safety devices (41) fed from certain of the conductors. The assembly, with the help of the electrical connectors, of a number of plates enables a false ceiling to be formed having all the necessary electrical installations required. The conductors are printed circuits partly integrated into the surface of the plates.
