68 NFS2-640/E Operations Manual — P/N 52743:F1 06/16/2011Appendix D: Point and System Troubles ListsThere are a variety of point or system trouble types that may appear in a trouble message. Thetables below give lists of the troubles and indications of their cause.D.1 Point (Device) TroublesA message from the “Trouble Type” column in the following table will appear in the upper right corner ofthe panel display when a point (device) trouble occurs. Use this table to help determine what the trouble is.POINT TROUBLESTROUBLE TYPE TROUBLE DESCRIPTION ACTIONAC FAILURE The auxiliary power supply has lost AC power. Determine whether there is an AC power loss or whetherthe power supply and wiring is correct.ADRFLT .Detector and new sounder base address doesn’t match. Or the ACPSaddress is incorrect.Readdress the incorrect device.ALIGN A beam detector is in configuration mode. No action is necessary, as the trouble will clear when theconfiguration is complete. However, the detector will notdetect a fire while this trouble exists.BLOCK Something has come between the detector’s beam and its reflector. Investigate and clear the blockage.CHGFLT* The power supply’s battery charger is not working properly. Correct the fault.CO 6MN The CO (carbon monoxide) detection element on a detector has sixmonths left to expiration. (This trouble generates in FlashScan modeonly. CLIP mode will generate a LO VAL error, if applicable.)Replace the detector.CO EXP The CO (carbon monoxide) detection element on a detector hasreached the expiration date. (This trouble generates in FlashScan modeonly. CLIP mode will generate a LO VAL error, if applicable.)Replace the detector.CO TBL The CO element on a detector is not working properly. (This troublegenerates in FlashScan mode only. CLIP mode will generate a LO VALerror, if applicable.)Replace the detector.DIRTY 1 The detector is dirty and needs cleaning Clean the detector.DIRTY 2 The detector requires cleaning immediately. It is a false alarm risk. Clean the detector immediately.DISABL The point has been disabled. Service and re-enable the point.GNDFLT There is a ground fault on the main or auxiliary power supply. Correct the fault.HI BAT The auxiliary power supply’s battery charge is too high. Check the batteries for problems. Replace batteries ifnecessary.INVREP The device has returned a response to the panel that the panel did notexpect.Check the device for functionality, addressing and wiring.IR TBL The infrared element is not working properly on an FSC-851 IntelliQuaddetector. (This trouble generates in FlashScan mode only. CLIP modewill generate a LO VAL error.)Replace the detector.LO BAT The auxiliary power supply’s battery charge is low. Check the batteries for problems. Replace batteries ifnecessary.LO TEMP The temperature read by a Heat+ or Acclimate™+ detector is too low. Raise the heat in the area of the detector.LO VAL The detector chamber reading is too low; the detector is not operatingproperly. Or (CLIP Mode only) the thermistors, CO element, or infra-redelement on an FSC-851 IntelliQuad detector is not working properly, orthe FSC-851 IntelliQuad is experiencing a freeze warning.The detector must be removed and replaced by anauthorized service representative.NO ANS The device (module or detector) is not responding to the poll. Either thedevice is not working or it is not connected properly.Determine whether the device is functional, andconnected and addressed properly on the SLC.NO SIG The device (module or detector) is not responding to the poll. Either thedevice is not working or it is not connected properly.Determine whether the device is functional, andconnected and addressed properly on the SLC.OPEN The module device has an open circuit on its supervised wiring. Check the connections from the module to the input oroutput device to which it is wired.OPEN ON x There is an open on speaker circuit x. Locate the open and fix.PSFAIL The power supply is not working properly. Check the battery for problems. Replace battery ifnecessary.PRLOSS The output module or new sounder base lost power. Turn power back on.SHORT The module device has a short circuit on its supervised wiring. Check the connections from the module to the input oroutput device to which it is wired.SHORT ON x. There is a short on speaker circuit x. Locate the short and fix.Table D.1 Point (Device) Troubles (1 of 2)
