While doing some cross training on NFPA 72, I came across the semi-annual requirement for testing of “Mechanical, electrosonic, or pressure-type waterflow device(s)” I, nor any of the other sprinkler experts here knew what an electrosonic waterflow switch was, and our alarm guys only had passing knowledge of them. Is this something the 13 committee has ever discussed?
