This quote is for 4 hours of additional troubleshooting time. If more time is needed contact customer for approval. Will need to return to finish tracking out NAC 3. I tracked it down the hallway on the 1st floor and then it goes into room 120, and then over to room 119, then to the hallway for the EOL. I moved the EOL to room 120 bathroom strobe to keep the system normal. We will need to return to track wiring from the 120 bathroom to the 119. Issue appears to be somewhere inside of that room. - repair
