D.2 System Troubles
A message from the “Trouble Type” column in the following table will appear in the panel display
when a system trouble occurs. Use this table to help determine the cause of the trouble.
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 or
output device to which it is wired.
SHORT ON x
. There is a short on speaker circuit x. Locate the short and fix.
TEST F This detector has failed the FACP’s periodic detector test for alarm
capabilities.
The detector should be removed and replaced by an
authorized service representative.
THERM The thermistors are not functioning properly on an FSC-851 IntelliQuad
detector. (This trouble generates in FlashScan mode only. CLIP mode
will generate a LO VAL error.)
Replace the detector.
VER HI This detector, which has been programmed to participate in alarm
verification, has gone into and come out of verification its programmed
limit without going into alarm. Either something is wrong with the
detector or there is a condition nearby (such as someone smoking) that
causes it to go into verification frequently.
Check the detector and the nearby conditions to
determine the problem.
XP TBL XPIQ general trouble. Check the XPIQ point for problems.
* This trouble may be fire panel or backup battery related. Test and replace backup batteries if necessary.
