Hello all,
I have a very old fire protection panel, my guess is from the 1980’s, the transformer has a date of 1985 so i’m guessing around 1985, it’s a chubb 1500 fire protection panel, i’m guessing single zone conventional panel, would anybody have access to the user manual, not sure if it would help me anyways. The panel is making a very loud noise with a trouble light. We recently changed the batteries as the batteries were quite old. I’m wondering if the panel is not charging the batteries properly or something is wrong with the charging component on the panel. Any help would be very much appreciated. Thank you
