Alarm Zone Fault Will Not Clear
Troubleshoot alarm zones that stay open, faulted or in tamper.
Start here: Do not replace hardware until power, cabling, configuration and the correct wiring path have been checked.
Step-by-step diagnosis
Confirm the symptom
Check whether the fault is constant or intermittent and whether it affects one device or the whole system.
Check power and cabling
Verify power, polarity, PoE, battery, terminations and patching.
Check configuration
Confirm IP address, zone, reader address, relay mapping, app registration or recording settings as relevant.
Compare with the diagram
Use the related diagram to confirm the device is wired to the correct input, output or network path.
Quick checks
- Check the physical detector or contact state.
- Verify resistor value and wiring method.
- Test continuity at the panel terminals.
- Confirm the zone type and programming match the circuit.
