tumult Posted July 23, 2010 Share Posted July 23, 2010 I have a septic system that sounds an alarm if there's a problem. There's a contact to monitor but it's high voltage. Does anyone know of a product that would work? Maybe the card access heavy duty piece but I'm thinking it won't work as my dealer has not mentioned it. I'm running 1.8.2xxxThx,tum Link to comment Share on other sites More sharing options...
henniae Posted July 23, 2010 Share Posted July 23, 2010 Just use a simple relay to convert the high voltage contact to a low voltage contact and then use a CardAccess contact switch or a contact switch on your C4 controller. Link to comment Share on other sites More sharing options...
