A few ATI's are on my route today. I'll post some pictures so you and others can interpret them.DJ2226 wrote: ↑Mon Oct 09, 2017 9:35 pmThat would be interesting to see the ATI heads on a Whelen panel. They might just be installing them for now and installing the speakers at a later date. Since the ATI horns are 400 watts each you can wire them up to the panel as if it's a 2908. All they'd need to is add the two extra amps in whenever they stick the new head on the pole and program the logic board to use them.
