How Do You Add a 2GIG SMKT2-345 to the 2GIG GC3?

You can add a 2GIG SMKT2-345 to a 2GIG GC3 security panel through the wireless zone programming menu of the system. The wireless programming menu is found within the installer toolbox. You will need the installer code for the system in order to access the panel's installer toolbox menu.

Complete the following steps to add a 2GIG SMKT2-345 smoke and heat detector to a 2GIG GC3 security panel:

  1. Access wireless zone programming. On the GC3 home screen, go to System Settings > enter the installer code (the default code is 1561) > scroll down > Installer Toolbox > System Config > Wireless Zones. You will now be at the wireless zone programming menu.
  2. Select an available zone. The left side of the screen displays all of the available wireless zones on the system. Programmed zones will be displayed in bold letters, available zones will be displayed in light gray. Select an available zone, then choose "Edit Zone". Now the programming options for the zone will be listed on the left side of the screen. When an option is selected, the programming parameters for it will be displayed on the right side of the screen. Program each option, then press the down arrow at the bottom right to move to the next option within the zone.
  3. Power up the detector. Install the included batteries into the SMKT2-345. Place it on its mounting plate, and click it into place.
  4. Program the detector. Begin with the first programming field named “Sensor Type”.
  5. Programming Fields

    Field Value

    Sensor Type

    "09 - 24-Hour Fire" or "16 - 24-Hour Fire Verification"

    The recommended setting for smoke detectors is 24-Hour Fire. This will immediately send an alarm signal to the system when the detector transmits a signal. 24-Hour Fire Verification requires that the detector be triggered twice within a 30 second period for the panel to go into alarm. This helps reduce potential false alarms but does potentially delay the fire alarm.

    Equipment Code

    0895 - SMKT2-345 GE Smoke/Heat

    Serial Number

    Click the Learn button on the bottom of the screen. Twist the mounting base until it clicks as if it were being removed. The serial number should learn into the system and display on the screen. Alternatively, you can press the TEST/SILENCE button on the device for a full 4 seconds, which will cause it to transmit a signal.

    Equipment Age


    This field has no bearing on the functionality of the sensor. We generally recommend end users select "new", but selecting "Existing" will not modify any of the panel's behavior.

    Sensor Loop

    "Loop 1"

    The SMKT2-345 only uses loop 1.

    Voice Descriptor

    Click the Edit button and select a descriptor for the device. The system only allows preset words for the zone. This descriptor will be spoken as part of the zone description for alarms and troubles, and will also be sent as part of any notification from

    Sensor Reports

    Enabling this will have the system transmit a signal to central station if an alarm occurs on the zone.

    Sensor Supervised

    It is recommended to enable sensor supervision. The system will continually monitor check-in signals from the device, and if it doesn't hear from the device within a certain period of time, an RF supervision message will be reported/displayed.

    Sensor Chime

    A sensor chime doesn’t need to be set for a smoke detector. The only time the detector will activate the system is when it triggers a fire alarm or a trouble condition.

  6. Return to the home screen. Once programming is completed, click “Return to System Configuration” in the upper right hand corner. Click the back arrow on the left side of the screen. Select “Save” to lock in all of your programming edits. Click the back arrow on the left side of the screen until the system is back on the home screen.
  7. Test the smoke. First, if the system is monitored, be sure to put it on test with the monitoring station to prevent a false dispatch. Hold a smoldering cotton ball directly under the smoke detector and make sure that smoke is going into the detection chamber at the center of the device. Canned smoke can also be used to test smoke detection. The system should go into a fire alarm within about 20 seconds. Disarm the system afterward to clear the alarm. When testing is completed, contact the monitoring station and take the system off test.
