| Error on LCD | Probable Cause | Manual Solution (Section #) | | :--- | :--- | :--- | | | A detector was physically moved from address 10 to 20 without deleting address 10 first. | Section 7.2: Use Auto-Program to relearn the loop, or manually Delete the ghost point. | | "NAC #1 OPEN" | You programmed a NAC as STROBE but the wiring is for a HORN . | Section 4.5: Change the Type Code to match the physical device. The panel checks resistance; a mismatch causes a trouble. | | "SLC LOOP FAIL" | You exceeded the 318 device limit or have a short on the loop. | Section 2.3: Check loop resistance spec (40 Ohms max). Disconnect the loop and split the circuit to isolate the short. | | "INTERLOCK FAIL" | A logic equation (CBE) references a zone or point that does not exist. | Appendix C: Run Logic Check utility. The manual states: "The panel will not accept a CBE referencing a null device." |
