Notifier System 500
I have four lights blinking on my panel the AC POWER SYSTEMS ALARM SUPERVISORY SIGNAL SYSTEM TROUBLE It is sending a supervisory to the communicator but I can't find anything wrong with the panel itself. It will stop for a few days if I power it down and back up. Any ideas as what I can do to fix it...
