Hi, I’m newbie here, currently we are working on 3 FACP on each building, I have this issue, every morning. the fault is always like these. to clear the fault I need to press PA Microphone and it will return normal status.
what is the model of the panel?
Provided this says “Fire Brigade Panel” I’m assuming you are not-US. I don’t know that panel in particular, but a line fault would usually indicate either a short or an open. It’s odd that it is coming on every morning, and without knowing more about it I cannot be too helpful (heck, not sure I even could with whatever this panel is). I’d check the circuits it’s warning you about: is there an open circuit? A short? Ground fault?
Your post makes it sound like it’s showing up on 3 panels. Are these networked together? So the faulty circuit is on one panel, but the other 2 show the fault?
Model of the panel: Fire Finder Plus
I’ll be checking the unit for maintenance this week, assuming the module for the OWS is the issue. Still puzzled, so I’ll update the post after I run my test
