Hi gang! Got a little issue with a Gamewell master fire box. It is local energy and hooked up to a school's FA system. (Note, this box issue is in regard to an working system in NJ). The box is not transmitting the box number. In addition, it is fluctuating between 50 and 100 mA. Its a short run of C-wire from the box to the main circuit (which is new multipair wire). The C-Wire run is about 200 feet. The C-Wire appears to be in good shape (no cracks, breaks, notches, etc). All connections from the main circuit to the terminal box, down to the fire box are tight. The box was taken apart and there is continuity and all parts appear to be in working order. It jumps from 100 to 50 to 100 mA despite wind. There is a good, new ground installed. The proper tangent supports and dead ends are used. Now, according to the fire chief, the box used to work fine until the school got a new FA system this past year. Again, though, all seems ok. In addition, I put the box on a VOM and the box was sending out the right voltage when it was activated. Any ideas?? :? Bob K
