The panel needs them so that it 'knows' that there is not an open/short circuit.Are end of line resistors used at sounders?I presume they arent needed because theres normally just sounder 1, sounder 2 etc. The ones I have been putting in are just obviously end of line at smoke detectors?
bit a of tangent there.....Twinflex system can have sounders and call points and smokes all on the same zone although i think they do have a sounder circuit also.
apart fromthose which use a dil switchAlways a EOL device
EOLMI have seen capacitors, diodes and other odd unrecognisable things
So basically the end of line of the sounder circuits where you have line neutraul and earth where the connections go in I presume the end of line resistor link will be between line and neutraul and this is needed?Yes they are
And what do you think the dil switch is doing then ?apart fromthose which use a dil switch
