Hi all - New to fire panel troubleshooting and getting started on a Cerberus Pyrotecnics mxl (Siemens) panel that has been discontinued.
The error condition is low battery. The batteries were replaced within the past 12 months. Multimeter tests show zero voltage across the batteries, 120V into the panel, 13.2v at the panel, and continuity across all fuses.
I seem to be missing the connection to/from the battery charger itself. Appreciate you sharing any experience or guidance.
