Hi, for those following the saga you will recall that I have discovered that my DSC system has been installed without the use of EOL resistors on any device with the exception of the Smoke Detectors.
I have three smoke detectors all homerun to the panel. The wires are all then by color twisted together and installed in a single zone. There is a 5600Ω across the zone and COM input on the panel. Now as the rest of the system is wired without EOL resistors and are NC circuits I am wondering.....
Question 1 - Why is the smoke wired this way? (Edit - I may have now figured part of this out - all smoke seem to be NO devices and require the EOL resistor to function but in further reading it seems that the smokes should be run in series with an EOL at the end of the run - mine are homerun so not quite sure what to do here).
Question 2 - Can I (should I) split the smokes into individual zones and place an EOL resistor at the smoke detector end of the wire? This is a little confusing as it seems that there is only a single entry for EOL installed or not in section 13 of the programming?
Question 3 - Are there any other devices for which EOLs would be highly desired? It is not practical for me to add them to all sensors as the house is fully finished but it would not be too hard for CO detectors, motions and the like.
Many Thanks,
