System Troubles
A message from the “Trouble Type” column in Table 2.2 will appear in the second line on the left
of the panel display when a device trouble occurs. Use this table to help determine the cause of the
trouble.
SYSTEM TROUBLES
TROUBLE MESSAGE TYPE TROUBLE DESCRIPTION
AC FAIL Loss of AC power to DAA. Investigate whether there is an AC power loss, or whether the DAA-PS is correctly
installed and wired.
ADV WALK TEST There is an Advanced Walk Test in progress.
AMPLIFIER TROUBLE The DAA is in trouble. The ouput is overloaded or the amplifier is damaged. Remove outputs to determine if the
DAA was overloaded. If it still does not work, call Technical Services.
ANALOG OUTPUT x
TROUBLE A trouble has occurred on DVC-AO analog output x (1 - 4). The analog output is configured for Style 7, but no
audio signal is returned. Investigate and fix.
ANNUN x
NO ANSWER The annunciator at address x is not responding.
ANNUN x
TROUBLE The annunciator at address x is in trouble.
AUXILIARY TROUBLE
Auxiliary device connected to the
NFS2-3030 CPU at J5 is in trouble or cable is missing.
AUXIN TROUBLE Generated when the auxiliary input is supervised (as determined in VeriFire™ Tools programming) and no
signal is coming from the input. Check wiring and source.
BASIC WALK TEST A Basic Walk Test is in progress.
BATTERY The power supply’s battery voltage is too high or too low. Check the batteries for problems. Replace batteries if
necessary.
BUZZER OFF-LINE The piezo is disabled.
CHARGER FAIL The DAA’s battery charger is not functioning. Investigate and correct.
CORRUPT LOGIC EQUAT The database that houses the panel’s logic equations is corrupt. It must be re-downloaded, or all programming
must be cleared and re-entered.
DAA NO ANSWER A DAA is not responding. Investigate and fix.
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 PORT x
A ground fault has occurred on DAP x (A or B).
GROUND FAULT LOOP x
There is a ground fault on loop x.
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 is lost between the CPU2-3030 or DVC and the NCM.
NETWORK FAIL PORT x Communication lost between NCM Port x and corresponding node.
NETWORK INCOMPATIBILITY An incompatible product exists on this network.
NFPA 24HR REMINDER This message occurs every day at 11 am if any troubles exist.
