PROBLEM TO BE SOLVED: To provide a transmission system for gaseous system fire extinguishing equipment of making it possible to signal transmit multiple signals with simple structure between a control machine and a operation box. SOLUTION: A signal transmission system for gaseous system fire extinguishing equipment transmits the various signals between an operation box 4, which is set on protection compartment A, B, and a control machine 9 that controls the operation box 4. Then at the signal transmission system for gaseous system fire extinguishing equipment, a serial transmission line 44, which transmits a serial signal, is set between the control machine 9 and the operation box 4 and a sending line for display 40, which serially converts multiple display control signals that are for controlling multiple display device set on the operation box 4, on the control machine 9 and a receiving line for display 43, which parallelly converts multiple display control signals that are received through the serial transmission line 44 and outputs it to each display device.
