- In the last video I began to show how to troubleshoot a ground fault, and in this one I expand on that a bit. I get into the different types of resistance readings your meter may show you and what those values mean in relation to each other.
I've learned a ton watching your videos. Fire alarm info is hard to find. Your explanation about the modules used for conventional smoke detectors (power source needed) was great. Would love to see an isolator explanation. Thanks for putting these vids together!!
Thanks Joe, i follow you since a long time now. 10 years Electrican here, Canada, we often wire Fire Alarm system. Then Tech FA company program the Pannel.
the best videos on youtube when it comes to FA , thank you
Watching this at 3am in a pump room to brush up while tracking an intermittent ground fault. 🤙
I'm that guy in the Facebook group 😂
Needless to say it was a bad device lol
Great vids man love em
Lol, that's awesome. Glad you figured it out. Feel free to reach out if you have anything I can help with.
Thanks, very helpful. I subbed 👍🏼
Great advice
I recently repaired a panel that had 1 "hard" earth fault plus 2 "soft" ground faults. In 35 years I have only come across this 3x and they are very difficult to solve.
Thanks Joe it is an amazing video,i just waana make sure that i understand it correctly
so basically here you are explaining about Nac output ? would it be the same for slc ?
at 8:13 u said threshold should be -100k or 100k ?
Hey! Maybe my intermittent ground fault is due to the resistance value temporarily meeting the ground fault detection level and then dropping below it again, for some reason.
Did you see my reply to your other comment on the other video?
So if you meter OL, you’re good and if you meter a value, then you should start paying attention is that correct?
If you meter OL to ground you're definitely good. If you rear anything in the Megaohm (M) range you're probably good, but the lower that number gets, the more of a problem it is. 5M Ohm to ground wouldn't concern me at all. 1M Ohm to ground would a little bit. 500k Ohm to ground would definitely concern me and I'd go find it (Unless it was Friday).
@@JoeKlochan so in the example would 3.2 be ok Joe?
Does the ground fault light go off without doing a system reset.... I removed all circuits from the card and still have the light!
Remove them all at the same time, remove batteries, aux power, etc. Nothing should be on your panel except your AC.
@@JoeKlochan I'll try that out, but I'm pretty sure I have already... if I install a new ILI(?) Card how much programming is there to do by a gamewell tech...as I am not...?
Hai sir system fault showing, i disconnecting all cables but same priblem showing, can i hep
I had more success with an old fashion analog meter for ground faults had a tamper switch that was leaking a little here and there got ground and fluke was always jumping around analog was yes or no .
50k to 100k sorry, that would be outside of the threshold by about 35k. 15k is the UL spec.
