Troubleshooting; Fault Fi Nding - Apollo 55000-268 Installation Manual

TROUBLESHOOTING

Before investigating individual beam detectors
for faults, it is very important to check that the
system wiring is fault free. Many fault conditions
are the result of simple wiring errors. Earth faults
on a data loop or any ancillary zone wiring may
cause communication errors.
Please also refer to Table 4 on page 17 for infor-
mation on diagnostics that may be supplied by
the beam detector.
