I have a Firelite MS-2 panel in my home. I am having issue where it is alerting error at panel randomly. It flashes System Trouble and Power Trouble and if you take off the cover the LED27-CHG Light is flashing. I have tried batteries, Tansformer/charger and new board and still goes off randomly. I have the battery cable on order to replace but any other thoughts. If you don’t get down to panel to acknoledge it will clear and go back to ready state on its own.
By “M2” do you mean “MS-2”? (since as far as I know there’s no Fire-Lite panel by the name of “M2”)
Yes, sorry updated model to MS-2
