Abstract: Fire-prevention control unit including several circuit boards and a dedicated communication bus for communication between the circuit boards, the circuit boards including at least one processing board, at least one input board and at least one output board. The at least one processing board is intended to process input data received from the at least one input board and to generate commands to send to the at least one output board, the at least one input board and the at least one output board being intended to communicate with one or more devices to be monitored or controlled. Each circuit board has two identical and physically distinct functional logic units, the functional logic units being adapted to perform the same function, each functional logic unit having a unit for direct communication with the communication bus according to a configurable architecture.
