akg4y Posted December 21, 2008 Share Posted December 21, 2008 I am looking into using the cardaccess doorbell sensors and thermistor and was wondering if anyone knows if two doorbells and one thermistor can be connected to a single wireless contact switch? Basically I want to do what is on page 5 here:http://www.cardaccess-inc.com/inhomeproducts/files/CA_IGA_1_3_Install_Guide.pdfHowever, instead of connecting to two garage contacts I would connect to two doorbell contacts. ie, doorbell one on pins 1&2, doorbell 2 on pins 3&2, and thermister on pins 4&2. Would that work?An unrelated question, on page 6 of that same PDF, what are the dotted relay connections seen above the wireless contact switch? I thought the whole point was that this didnt need to be connected via wires to the HC-300 etc? Link to comment Share on other sites More sharing options...
