CHeKT Bridge Relay Operation (V2 or Above)
This new function is only available with CKB304 Version 2 or better hardware.
Hardware Connection :
- The CKB304 V2 has a relay output that can be energized from both the Dealer and Monitoring Portals.
- Terminal location:

- 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. '
- 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,
- 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.
- 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:

- 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):


- Enable Relay Toggle
- Toggle to show selected button overlayed in monitoring portal
- Name the Relay
- Current Relay Status (Normal/Energized)
- Click Status Label/Icon to open Labeling Options:

- 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.
- Same Idea, but the picture overlayed on the "button" in software. Some options include:

- 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:

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

- Latch: Click Checkbox to enable. When energized, state will maintain that status until canceled by portal user or Six hours passes.
- Momentary: With the slider set the number of seconds a momentary trigger will keep the relay state energized.
- 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
- 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
- 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.
- Clicking it (on the picture of the relay in the map) will bring up the camera Associated with the relay.
- Click on the Relay option at the top right:

- 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.
- Click on the status to open activation buttons:

- With the full menu expanded, you can activate a "latch" with the top button, or a Momentary with the bottom button. You see my status option is to "set to Open" as opposed to "energized."
