Definition
A firing system is the electronic ensemble that replaces the hand torch: a control desk or computer, receivers (modules) spread across the site, and lines linking each output to an electric igniter. When a cue fires, the module sends one to several amperes through the igniter, bringing the bridge wire to incandescence and lighting the pyrotechnic head, then the product's fuse. Modern systems are wired or radio, battery powered, with continuity testing of every line, key arming, emergency stop and playback of a time-stamped script or a timecode for pyromusicals. Electric firing makes it possible to fire remotely, outside the danger area, with hundredth-of-a-second precision and full traceability of what was fired.
In practice, for the display company
The choice of firing system dictates the number of cues available, the wiring method and the export format of the timeline. PyroDesk describes the company's fleet of modules, distributes the firing-plan cues per module, and exports the time-stamped list in a format the desk can read, with no need to re-enter the times.
