Troubleshooting
Error Messages
The GDCP-Touch is programmed to display error messages to indicate a problem condition
with the unit. The bottom center of the
Home Screen
will scroll through each message
present. When an error occurs, the alarm will chirp and a silence button will replace the
calendar icon to allow a user to mute the alarm. Any associated Level 1 relays (if able) will
activate during an error state.
Relay # – Manual Override Active
While not technically an error, the manual override prevents the panel from operating normally.
This message will appear whenever any relay is being forced on or off by a manual override.
Setting the manual override to “None” will clear the error message.
Sensor # Communication Loss
This error message means that the panel is unable to communicate with the indicated sensor
and attempts to reestablish communication have failed. Once the panel is able to
communicate with the sensor again, the error message will clear.
The most common reason for this error message is improper wiring. Another reason is that the
transmitter is addressed incorrectly, either matching the designation of another transmitter or
being set to an inactive address.
Sensor # – Calibration Expired
Each sensor has an internal timer that indicates to the control panel when the recommended
recalibration date occurs. This timer is approximately 2 years from the previous calibration.
When this error message appears, test the sensor to verify its response. If the response is still
acceptable, the error message may be cleared with the “Clear” button; it will return in 6
months. Otherwise, recalibrate the sensor or replace the sensor board to clear the error.
Sensor # End of Life – Please Replace
When a sensor reaches the expected end of its useful lifetime, this error message will be
shown. 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.
