How Do You Add a 2GIG CO3 to the 2GIG GC3?

You can add a 2GIG CO3 to the 2GIG GC3 from the system programming menu of the GC3. This menu is also where you can change any settings for the detector. You will need the installer code to access the system programming menu. Test the device after it has been programmed into the panel.

Complete the following steps to add the CO3 to the GC3:

  1. Verify Compatibility. The GC3 must be at version 3.0.1 or higher to support the 2GIG C03. You can access the firmware update file from our site.
  2. Access zone programming. From the home screen of the GC3, go to System Settings > enter the Installer Code (the default code is 1561) > Installer Toolbox > System Configuration > Wireless Zones. You will now be at the zone programming menu.
  3. Program the CO3. From the left hand menu, select an available zone and click "Edit". You will now be able to program the CO3 and set all of its configuration options. Once you program an option, press the down arrow to move to the next option. The table below shows all of the programmable fields and the corresponding selections that should be made:
  4. Programming Fields

    Field Selections

    Sensor Type

    “14 - 24-Hour Carbon Monoxide”

    This zone type will cause an alarm regardless of whether the panel is armed or disarmed, and it can not be bypassed. When activated, it device will emit a repetitive pulsing sound (4 rapid beeps, pause, 4 rapid beeps, pause).

    Equipment Code

    “0860 - CO1-345 CO Detector”

    Even though the equipment code has the “CO1” listed, it will still function as the CO3 without any problems.

    Serial Number

    The serial number can be manually entered or learned-in automatically. To learn-in the serial number, click the “Learn” button on the panel, and then twist and remove the mounting base of the CO3. The serial number should appear in the learn window. Press "Accept" if the number displayed is correct.

    Equipment Age

    This field makes no difference in sensor operation. Select "New" or "Existing".

    Sensor Loop

    The CO3 uses Loop 1.

    Transmission Delay

    This setting can be ignored for Carbon Monoxide zone types, but set it to "Disabled" just to be safe.

    Voice Descriptor

    Program a descriptor for the carbon monoxide detector. This will be displayed for the zone, and the descriptor will be spoken by the panel in the event of an alarm.

    Sensor Reports

    With this enabled, the GC3 system will send a signal to the central station in the event that the CO3 triggers an alarm.

    Sensor Supervised

    All carbon monoxide detectors should have this field enabled. Enabling this option tells the panel to listen for check-in signals from the CO3. If the panel fails to hear from the detector for a specified amount of time, a trouble condition will be indicated.

    Sensor Chime

    Since the CO3 only faults in the event of an alarm, or when its tamper is activated, setting a chime for the device isn’t needed.

  5. Return to the home screen. Click “Return To System Configuration” in the top right corner of the screen. Then, click “Save” to confirm all of the programming changes you just made. Click the back arrow in the upper-left corner of the screen to return to the home screen.
  6. Test the CO3. If the system is monitored, make sure to put the system on test with the monitoring station first. On the detector, there is a Test/Hush button. Press and hold the button for at least 5 seconds. The CO3 will sound an alarm locally, and it will also transmit an alarm signal to the GC3.
