NFS2-3030 Programming Manual — P/N 52545:A 11/29/2005 135
System Troubles
DAP PORT x FAILURE Digital Audio Port x (A or B) is not communicating due to a break in the connection, a short, or
faulty hardware. Locate and fix the break or short. If the problem is not a short or break, call
Technical Services.
DIGIN TROUBLE The DAA has determined that its DVC has stopped transmitting audio data to the Digital Audio
Loop (DAL), even though the loop is still functional. Update code, ensure all code on the DAL
is compatible. If the DVC still does not transmit digital audio data, call Technical Services.
DRILL INITIATED Drill has been initiated locally.
DRILL RECEIVED Drill has been initiated remotely.
EPROM ERROR The application and/or boot code is corrupt. Service required.
EXTERNAL RAM ERROR The external RAM test failed. Service required.
FLASH IMAGE ERROR The software is corrupt. Re-download the panel code software from VeriFire™ Tools. If the
trouble does not clear, call Technical Services.
FFT TROUBLE There is a short or open on an FFT riser on a Digital Audio Loop. Check that the DVC’s 4-wire
switch is set properly and that there is an end-of-line resistor in place for 2-wire operation.
GROUND FAULT A ground fault has occurred within the panel.
GROUND FAULT LOOP x
There is a ground fault on loop x.
GROUND FAULT PORT x
A ground fault has occurred on DAP x (A or B).
INTERNAL RAM ERROR The internal RAM test failed. Service required.
LOADING.NO SERVICE A program or database download is in progress. The panel is NOT providing fire protection
during the download. Proper authorities should be notified while a download is in progress so
that other means of fire protection can be supplied.
LOCAL MIC TROUBLE The DVCs local microphone is in trouble. There is no communication, or paging has been
enabled for over 28 seconds and no signal has been received. Investigate whether the mic is
plugged into the DVC, or whether there is a problem with the local mic.
LOCAL PHONE TROUBLE The DVC’s local FFT handset is in trouble. TThere is no communication, or paging has been
enabled for over 28 seconds and no signal has been received. Investigate whether the
handset is plugged into the DVC, or whether there is a problem with the handset.
LOOP x
- x COMM FAILURE Loops x and x are not responding. The LCM and LEM for those loops must be serviced.
MAN EVAC INITIATED Local initiation of DRILL
MAN EVAC RECEIVED Network initiation of DRILL
MANUAL MODE ENTERED An annunciator has been placed in manual mode.
NCM COMM LOSS Communication lost between CPU2-3030 or DVC and NCM
NETWORK FAIL PORT x Communication lost between NCM Port x and corresponding node.
NETWORK INCOMPATIBILITY The brand of this panel is incompatible with this network.
NFPA 24HR REMINDER This message occurs every day at 11 am if any troubles exist.
NVRAM BATT TROUBLE Battery backup and/or clock backup is low. Replace battery.
NO DEV. INST ON L1 No devices are installed on the system.
NO POWER SUPPLY INST The address of the main power supply has not been entered.
PANEL DOOR OPEN The panel door is open.
POWER SUPPLY TROUBLE There is a communication failure with the DAA onboard power supply. Call Technical Services.
PRINTER OFF LINE Communication loss with printer. Restore power and/or printer’s online status.
PRINTER PAPER OUT Add paper.
PROGRAM CORRUPTED The database that houses the panel’s programming is corrupt. It must be re-downloaded, or all
programming must be cleared and re-entered. Service required.
PROG MODE ACTIVATED A user is currently using the panel’s programming menus.
REMOTE DISPLAY x
NO ANSWER The remote display at address x is not responding.
REMOTE DISPLAY x
TROUBLE The remote display at address x is in trouble.
REMOTE MIC TROUBLE The DVC’s remote microphone is in trouble. It is installed and supervised, but no signal is
coming from it. Investigate and fix.
SELF TEST FAILED Diagnostic test failed. Service required. Call Technical Services.
SOFTWARE MISMATCH One or more LCM or DAA software revisions do not match other LCMs or DAAs, and/or the
NCM is not network version 5.0, or LCD-160 software is incompatible. Update the software as
necessary.
STYLE 4 SHORT x
LOOP x Service required. Call Technical Services.
STYLE 6 POS. LOOP x
There is a short circuit on the positive side of loop x. Style 6 and Style 7 are supervised methods of
communicating with addressable devices. If the control panel detects a trouble (open or short), it
will drive both ends of the loop, maintaining communication in an unsupervised method. The
latching trouble will display on the panel as a Style 6 trouble until you correct the condition and
press reset. Style 7 configuration of the SLC requires the use of ISO-X modules.
