I have 4 connected to a ZW postwar for accessories. Three of them on 4 amps and one on 8. I removed D11 since I shorted a couple with a CW 80. In general I use the 36 volt transorbs that GRJ recommends. Maybe the 33s. I have both.
I have the sonic alerts but not installed, seems pointless and noisy since I can see if something goes dark. I forget what reset switch but they are on the boards.
