Abstract

The present invention relates to a security arrangement (10) wherein one or several input functions or input devices (2a, 2b, 2c) co-operate with a control unit (30), each input function being adapted to be able to transmit to said control unit a first information item and said control unit being adapted to, upon receipt of said information, initiate and/or accept a selected output function (37a), said control unit (30) also being equippped with a computer (40) and having a number of input gates (31', 32', 33') and a number of output gates (21', 22', 23'), the former adapted to co-operate with at least said input functions (2a, 2b, 2c). A pulse-related active output signal (37a') is directly generated via software (42, 44), such as a test program (42), pertaining to a computer unit (40). Said pulse-related active output signal (37a') is inhibited in the event of malfunction of one or several internal circuits or functions activated by the software (42, 44), and/or said active output signal (37a') is inhibited in the event of malfunction of the software (42, 44). A circuit switching network (51, 52) constitutes an AC-connected energy transferring circuit having galvanically isolated primary and secondary sides. If the pulse generation on the output gate (37') disappears the output function (54) will not be activated.
