Figured out the issues..
Went to site this morning and did some troubleshooting. Since the drawing showed 4 heat detectors and there are 7, an abandonned one, and an EOL first mission was to make a drawing... Found numerous bad connections along the way, so redid all of them. Found 2 - 4" pieces of wire spliced together to make an 8" piece for the EOL, so I replaced that. Went to the panel and couldn't read the EOL... Went to the last detector and couldn't read it there either.. Opened it up and when I went to check the factory side, one lead broke out of the end of the resistor. Had to leave it in "trouble". Tested the detectors and they all but one rang in, so removed that one and jumperred it out... Removed the fault contacts from the shutdown string to the PLC and hooked it all back up...
New detectors, and EOL on order..
Found out it wasn't a 2280 as I thought.. It is a 1527.. Recommended an upgrade to maybe something at least out of the 90s...
