Gamewell 28922 is the main logic/control board used in Honeywell‑Gamewell ZANS fire‑alarm panels (e.g., ZANS 200/400). Common failures on this board include burned or tripped protection diodes, failed microcontroller ICs, and damaged power‑regulation capacitors; symptoms often present as panel lock‑up, “no communication” errors, or intermittent reset cycles. First‑check diagnostics: verify the 24 VDC input supply and monitor output rails for correct voltage levels, inspect the board for visible burn marks or swollen electrolytics, and review any error codes displayed on the panel’s status LEDs or console.[oss-gpt-20b] |
