Some background:
I have multiple high-water/water leak sensors, most are the two-prong type, but I also have NC float sensors on the my sump and sewage pumps and window well.
1) The 2-prong NO (Chinese made purchased on eBay, can't figure out how to post a link) will not work with EOL resistors - I assume it has something to do with the resistance they are looking for when water touches both prongs? Note: I did test it with the resistor in parallel but it did not work).
2) The NC float values work fine with or without an EOL resistor.
3) I have all these sensors set up as Zone Definition 25 - Water Alarm 24 Hr. When any of them "trip" I get a loud audible alarm and siren and the system sends me a text message.
4) When I first set up my system I did not understand the value of EOL resistors, I am now adding them to al the "important" sensors (except for the 2-prong leak sensors) that I still have access to.
5) My two prong and float sensors (set to NC) were working perfectly with the water zone definition. But this weekend I added an EOL resistor (in series) to one of the float sensors and it is no longer working properly. The alarm does recognize that it is tripped BUT it does not give the Water Alarm/Siren nor send the text message. Note: this issue did not affect the 2-prong sensors - they still work fine.
Now my question. Why would adding an EOL to the float sensor cause an issue? (I did change its type from NC to EOL) Is there a way to fix this or do I have to remove the EOL resistor and go back to an NC configuration?
Thanks in advance,
Tom
