A lot of people use their electrical firing systems today with a bit of luck. They run their wires, attach their e-matches, and hope for the best. This session will shed some light on how electrical firing works, and how to get the most out of electrical firing, especially when using one cue to fire multiple devices. You will learn how some common types of initiators work, how to wire them in both serial and parallel arrangements (and which style is best in certain situations). We will discuss the simple “ohms law” and it’s use in electrical firing. We will also show some rules of thumb to simplify the calculations when using long runs of wire of various lengths and diameter. Finally, we will also touch on cold-weather firing of devices, and why certain types of initiators are better than others. With a pencil and a calculator, you can take the guesswork out of your site planning.
