Research output: Patent


An electrical switching system (100) has an access control subsystem (110) and a plurality of slave control subsystems (120). The system (100) is applied to a building or installation having a master electricity input (12, 12.1) connected to a distribution unit (10) which splits the master electricity input (12, 12.1). The access control subsystem (110) is at the master electricity input (12) and includes a master switch (112), a user input arrangement (114) operable to receive a coded input from a user, and a master controller (116) operable to open or close the master switch (112). Each slave control subsystem (120) is provided downstream of the distribution unit (10) includes a slave switch (122), a sensor (124) operable to receive an external signal, and a slave controller (126) operable to open or close the slave switch (122). The electrical switching system (100) provides course control of the whole building or installation by means of the master control subsystem (110) and fine control by means of the slave control subsystems (120).
