FIRE-LITE ALARMS FCPS24S6RB REPL BRD F/FIL-FCPS24FS6

in this video i'm going to be replacing the backup batteries in this firelight uh fcps24 so the first step is i'm going to go ahead and get my fire light key and this power supply is energized so you have to be careful um a lot of that right there is high voltage so you can't touch that obviously here are the two batteries that we're replacing um there's got your neck circuits there's some field wiring and this right here is just the slc so don't worry about that all you do is pull out these batteries so the first thing is to actually go ahead and pull off this wiring harness right here which connects the board right there and you can see the battery light has came on and you can probably hear the lcd lcd adf upstairs is uh beeping because this is in trouble so it's going to show a knack fault since this is supervised by the knack circuit on the ms9200 so i don't want to go all the way
