Hi Nick;nickd said:I understand that the Elk uses 1.0 ohm resistors which is difference from Caddx. I don't have access to the EOL resistors and it would be impossible to swap them out. Is there a way to still use the Elk with the 3.3 resistors that my Caddx panel uses?
So Nick, based on what Spanky posted I would NOT "just" use the 3.3K Ohm resistor that is already in place even though I posted above that it worked. The reason is that it yielded 8.3 volts to the panel, but the upper threshold as reported by Spanky is 8.8 volts. This value (8.3 volts) is to close to the alarming threshold.Spanky said:The lower switching Threshold for circuit shorted is 3.9 volts, the upper switching Threshold for circuit open is 8.8 volts.
