OI-6940 Notis Quad Troubleshooting Guide
•
Fault 4
Reason:
The Notis Quad's analog sensor board not responding
Solution:
Ensure that the analog board is properly connected; replace analog sensor board if still in Fault

•
Fault 5
Indicator:
F5 NULL Failed Check Sensor Voltage
Reason:
1. If the voltage is wrong—on a positive sensor, “F5” will be displayed if the voltage is above 1
volt. On a negative sensor, “F5” will be displayed if the voltage is less than 1 volt (or higher than
2.4 volts).
•
Positive sensors are: H2S, SO2, CO, HCl, NH3, H2, ClO2, HCN, F2, HF, CH2O.
•
Negative sensors are: Cl2, O3, NO2.
•
LEL and O2 are both different from any other sensor and from each other. When using an
O2 sensor, “F5” will be displayed if the voltage is outside the voltage range of working.
2. If the Notis Quad cannot communicate with the sensor.
Solution:
Check the voltage of the sensor. Replace the sensor if still in Fault
Ensure that the sensor is properly connected. Replace the analog sensor board if still in Fault

Fault 6
Indicator:
F6 Fault while trying to autocal
Reason:
The sensor did not read any gas.
Solution:
Make sure the calibration gas bottle and regulator are properly connected.
Ensure that the sensor is properly connected.
Replace gas bottle/regulator if empty or defective.
Replace the sensor if problems persist.

Fault 14
Reason:
No primary monitor
Solution:
Ensure that a primary monitor is on
Ensure that the sensor assembly and monitor are set to the same radio address and Network ID
