I saw that! To me it also feels like a cross between Simplex and RSG’s T-bar pulls. The alarm signals at the school also felt like an unusual combination of the Amseco Select-a-Horn/strobe, System Sensor SpectrAlert Classic and Simplex TrueAlert. (Of course back in 2002, horn/strobe fire alarm systems were kind of rare in Canadian schools, as many still had bells at the time. But here in the USA, it was the other way around…)
