Thanks for your input...I use input B and mode 3. The powerflash does what I need which is triggering a AHP macro that turns on my flood lights and starts my cameras recording when my alarm system makes a closes a NO connection.
My problem is that the last 2 have failed in themselves. I have taken them apart and the components are burnt smelling.
I think the XPT3 would do what I need, I just wasn't sure if it was basically the same circuitry as the powerflash. I may have to look into a Insteon 2450. Again, thanks for your help.
