In alarm wiring, a zone should show a trouble indication when which condition occurs?

Explanation:
Zones are continuously monitored for faults in the wiring that could prevent proper detection. A short in the zone wire creates an abnormal condition on the loop that the control panel cannot interpret as normal sensor status, so the panel flags a trouble to signal a wiring fault that needs repair. An overloaded circuit usually trips protection rather than producing a zone-level trouble, a sensor failure is a device fault that may show as an alarm or separate fault, and a battery failure is a power issue affecting the whole system rather than the integrity of the individual zone.
