Brasch GSE Generation 2 - Transmit Timeout - 9501; Failed Sensor - 960 x; Cannot Run Self-Test - 9802; End-of-Life - 9995

The most common reason for this error code is improper wiring between the sensor board and
control board. Another reason is that the sensor is numbered incorrectly, either matching the
designation of another sensor or being set to a number set as inactive on the control board.
Cannot Run Self-Test – 9802
The self-test feature can only be run when the all alerts are inactive. If the detector is
measuring gas concentrations in excess of any active zone’s Low Alert level, this error code
will be displayed.
To clear the error code, allow the gas concentration to drop and the alert to clear. Then restart
the self-test. Alternatively, restart the unit to clear the error code.
End-of-Life – 9995
When a sensor reaches the expected end of its useful lifetime, this error code will be shown
while the sensor is active. This will be approximately 10 years from the original manufacturing
date for both Carbon Monoxide and Nitrogen Dioxide sensors. The signal is triggered by a
clock in the sensor board. In the event that the unit loses power, a supercapacitor will maintain
the clock for up to three weeks. While this error code is being displayed, any zones with
expired sensors will be unmonitored and the unit will close the Low Alert and Alarm contacts to
enable constant ventilation. The proportional output will also send a 0 mA or 0 V signal
depending on the output settings.
When this error code appears, replace the sensor board.
Sensor Not Installed – 9996
If no gas sensor is present on the sensor board, a 9996 error code will appear on the display.
Verify that there is a sensor on the sensor board and that it is fully seated in its socket. If not,
place the sensor firmly into the socket. If the issue persists, the sensor detection switch may
need to be replaced.
Invalid Calibration Values – 9997
When a sensor board does not have zero and span values saved in memory, this error will be
shown. This is often due to damaged or corrupted memory.
Replace the sensor board to correct the error.
