I have a old FCI 7200 Micro panel here. I’m a Notifier ESD so I’m not too familiar with FCI. I’m having an “alert” trouble on a duct detector. The head has been replaced already. But for some odd reason it was normal when first replaced, but now I’m getting this “alert” trouble. When I remove the head and reset the panel, and put it back, it normal again. But after a few days or so the “alert” trouble returns. Any help on this ???
