The PICO-GUARD is an electronic device. Won’t it provide a source of ignition when it turns on or off?
NO! At least not the fiber optic portion. Optical fibers are basically light conduits, piping a controlled amount of red light from the controller to the point of guarding and back. Because the optical energy is limited it will not provide a source of ignition, therefore the optical elements of the PICO-GUARD can be located within the explosive environment. However, the PICO-GUARD controller and any other electrical device interfaced to it must be located away from the explosive environment or within an explosion-proof housing.
