SYSTEM TROUBLES
TROUBLE MESSAGE TYPE TROUBLE DESCRIPTION
ADV WALK TEST There is an Advanced Walk Test in progress.
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 CPU-3030 at J5 is in trouble or the cable is missing.
BASIC WALK TEST A Basic Walk Test is in progress.
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.
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.
GROUND FAULT A ground fault has occurred within the panel.
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.
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 CPU-3030 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.
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.
SELF TEST FAILED Diagnostic test failed. Service required.
SOFTWARE MISMATCH One or more LCM software revisions do not match other LCMs, and/or the NCM is not
network version 5.0, or LCD-160 software is incompatible.
STYLE 4 SHORT x
LOOP x Service required.
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.
STYLE 6 NEG. LOOP x
There is a short circuit on the negative 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.
STYLE 6 SHORT 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.
SYSTEM INITIALIZATION One or more devices (detectors or modules) can not report activation. This can occur
following system startup, when exiting Walk Test, or following a device trouble of No
Response.
