In the past, wands with polder were used to fireworks ignition. But the proximity of the operator with the explosive tubes (or parts) was very dangerous and needed a new system more safety. Nowadays, ignition of each tube or explosive device is made from a firing case, located near the management place, using electrical igniter [1]. These igniters provide to convert electrical power in a flame which ignites mortar tube. Igniters are connected to the firing system by electrical wires called shooting wires. To provide easier network of shooting wires, which may be complex, it is possible to add electrical relays in this network to reduce the number of connexions rising management place. Then, the manager selects a wire and demands ignition of selected mortar tube. This kind of classical design needs a lot of time to installation and uninstallation (Image 1). More difficulties can be added like: presence of water, high installation… This kind of solution is also expensive with shooting wires (copper electrical wires).
