Stewbow Posted July 3, 2007 Share Posted July 3, 2007 When you said you moved the end of line unit from zone 4 to zone 3, was that with the circuit cables removed, with the end of line unit connected direct into the panel? Link to comment Share on other sites More sharing options...
whizzkid Posted July 3, 2007 Author Share Posted July 3, 2007 zone 3 had about 4 detectors and 4 call points wired with an eol reistor and was in fault zone 4 just had an eol resistor moved the resistor from 4 to 3 moved detecotrs + cp's and eol from 3 to 4 zone 4 works fine now zone 3 still in fault Link to comment Share on other sites More sharing options...
