CHeKT Bridge Relay Operation (V2 or Above)

CHeKT Bridge Relay Operation (V2 or Above)

This new function is only available with CKB304 Version 2 or better hardware. 

(Unsure? https://support.chekt.com/portal/kb/articles/which-hardware-version-is-my-bridge)

Hardware Connection : 

  1. The CKB304 V2 has a relay output that can be energized from both the Dealer and Monitoring Portals. 
  1. Terminal location:


  2. As with most security hardware, there is continuity between the NC (normally closed) and C terminals in a non energized state, and no continuity during an energized state. '
  3. The reverse is true for the NO (normally open) terminal; there is no continuity between the NO and C pin when the relay isn't energized, and continuity when the relay is energized, 
  4. Circuit independent from Alarm Inputs and Arming Input

Portal Configuration

The relay output is not a premium function, and will be available to anyone installing a V2 or newer CKB304. Always remember to verify the central station has a plan in place to utilize the relay for your desired function - additional CS fees may apply.

  1. After Registering an applicable Bridge on an up-to-date software build, you will immediately notice the Relay is listed in your Device List in the Dealer Portal:



  1. Mouse over the Rely to see the familiar configuration gear and map location button (identical to those of the IP camera in the device list): 





    1. Enable Relay Toggle 
    2. Toggle to show selected button overlayed in monitoring portal
    3. Name the Relay
    4. Current Relay Status (Normal/Energized)

  2. Click Status Label/Icon to open Labeling Options:



      1. Name the Status Options. This is for something like "Pump on" "Pump Off" "Gate Secure/Ajar" Etc. These labels will be visible in the Monitoring and Dealer interface. 
      2. Same Idea, but the picture overlayed on the "button" in software. Some options include:   

  3. Click Associate Camera to open the camera assignment window. You can select from already connected cameras on that Bridge to associate a camera stream with the relay; changing states will create a snapshot event sourced from that stream:




    1. Select the camera (only 1 of 4 possible shown) and click "assign"
  4. Click Type of Control to configure relay state change specifics:



    1. Latch: Click Checkbox to enable. When energized, state will maintain that status until canceled by portal user or Six hours passes. 
    2. Momentary: With the slider set the number of seconds a momentary trigger will keep the relay state energized.
    3. Automatic Control: Energizes the relay anytime the Monitoring Portal Opens.
    4. On the left, you can test either right from this screen while configuring, and the top box is where the thumb of the assigned camera will be displayed. 

Monitoring Portal

  1. Verify you have enabled the relay toggle in your monitoring portal, and choose your custom images for the button that the operators will see (optional):



Launch  the Monitoring Portal
  1. You will immediately notice a "relay" button at the top right near the event toggle, and your relay will show on the map just like the cameras do.
  2. Clicking it (on the picture of the relay in the map) will bring up the camera Associated with the relay. 


  1.      Click on the Relay option at the top right:



  2. You will see the Status of the relay, using the custom label if you have selected One. I made this one a "door" who is currently "closed" as the relay is in the normal state. 
  3. Click on the status to open activation buttons:



  4. With the full menu expanded, you can activate a "latch" with the top button, or a Momentary with the bottom button. 

Thanks for reading, and have fun!
