A DB25 connector is provided to remote monitor line conditions.
These pins when in “good” condition are 12V. Once a circuit
becomes “open”or “short” the voltage switches to 0V or ground

Fig. 4 Common Fault Detection
If required the unit can be set up to trigger a relay contact whenever
ANY zone fault occurs eg, Whenever any zone from 1-10 becomes
OPEN or SHORT. Further problem diagnosis can then be determined
from the front panel as required.
