Fire Alarm panel keeps going in and out of trouble. Trouble will drop out all of loop 2 but in a matter of seconds put panel back to normal. As soon as it goes into trouble it goes right back to normal. I’ve disconnected devices on loop 2 but still having the same issue. It happens when it rains and i’ve looked for leaks, but yet no luck. Has anyone been through this?
One of your devices is getting wet. Try splitting the loop and connecting only half and see if the condition still exists. If it works then your issue is in the unconnected part. If its still intermittent, split the loop again and retry. Also check and see if there is an earth ground on the loop.
