Common Gamewell FCI S3 Trouble Codes
- SLC LOOP OPEN: A complete physical break in the signaling line circuit wiring has occurred, stopping the main panel controller from successfully polling downstream smart sensors.
- GROUND FAULT: Positive or negative voltage from a field loop or local horn-strobe circuit is bleeding to earth ground, typically caused by a pinched wire against a metal backbox.
- INVALID REPLY: The panel is receiving scrambled or unrecognized data from an addressable device on the loop, indicating communication interference or a damaged sensor head.
- BATTERY TROUBLE: The secondary power supply system has detected missing, disconnected, or degraded standby batteries during an integrated system load test.
