3 Troubleshooting and Test Functions
Compensation Sensor Open
The ambient-compensation sensor (NTC) on the detector main board in the
detector has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
detector main board is dependent on ambient temperature. The change in
resistance is used by the leak circuit to compensate for ambient temperature
changes. If the resistance across the sensor increases above the upper limit,
the error message is generated.
Probable Causes
• Defective detector main board.
Suggested Actions
✔ Exchange the detector main board.
