NFS2-3030 Programming Manual — P/N 52545:K1 03/20/2012 147
System Troubles
DSBUS x AC FAIL The DSBUS at address x has lost AC power. Check wiring and source.
DSBUS
x COMMFAIL The DSBUS at address x is not communicating with the fire panel. Check wiring and source.
DSBUS
x HIGH BATT The battery voltage for the DSBUS at address x has exceeded 28 V. If the batteries are shared,
ensure that only one power supply is charging the batteries. Remove the batteries and measure
the charging voltage from the supply to ensure it is not exceeding 27.6 V. Call Technical
Services.
DSBUS
x LOW BATT The battery voltage for the DSBUS at address x has fallen below 20.4 V. Charge or replace
batteries.
DSBUS
x SELF TEST FAIL A device on the DSBUS at address X has failed self test. Reboot the device. If this does not
repair it, update the software of the device. If the self test fail trouble continues to be displayed,
call Technical Services.
EPROM ERROR The application and/or boot code is corr
upt. 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 proper
ly 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).
HARDWARE MISMATCH The device installed does not match what was previously installed. Inst
all the correct device.
INTERNAL RAM ERROR The internal RAM test failed. Service required.
INVALID NODE TYPE MAPPED An invalid node type has been mapped to the NFS2-3030 for Network Display Mode. Check
network mapping and cor
rect. Refer to “Limitations” on page 152 for valid network types.
INTERNAL RAM ERROR The internal RAM test failed. Service required.
LCD80 SUPERVISORY Communication has been lost with an LCD-80.
LOADING...NO SERVICE A program or database download is in progress. The p
anel 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. T
here 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.
MODBUS COMMUNICATIONS
FAU
LT
The VESDA
®
Gateway can not communicate with the HLI, HLI may be damaged or not
powered, or the VESDA Gateway may be damaged.
NCM COMM LOSS Communication lost between CPU2-3030 or DVC and networ
k communications module.
NCM CONNECTION LIMIT
EXCEEDED
More than two panels have been connected to a high-speed network communications module.
NCM SNIF
FER MODE ACTIVE The network is in a diagnostic state.
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.
NETWORK MAPPING LIMIT
EXCEEDED
More than 1 fire panel or more than 4 DVCs has been mapped to the NFS2-3030 for Network
Di
splay Mode. Check network mapping and correct.
NFN PAGING CHANNEL LIMIT
EXCEEDED
Multiple paging sources are attempting to page over the NFN, exceeding the limit of one (1).
reduce the number
of paging sources to clear this trouble.
NFPA 24HR REMINDER This message occurs every day at 1
1 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.
PHONE CHANNEL LIMIT
EXCEEDED
The DVC has allocated all its phone channels, and there are still phones ringing in requesting
mor
e channels.
PO
WER SUPPLY TROUBLE There is a communication failure with the DAA onb
oard pow
