I hooked the PSC01 into my alarm system Bell
output (~12 Vdc when active). I set the
switches to Input A, Mode 3, and code E13. I
set up a Lamp module plm03 to E13 and it
comes on ok when the alarm activates and
turns off when the alarm is reset. I also
set the powerhorn ph508 to E13 but it does
not respone. why?
