The users can set the downtime for a particular facility, from the Test Request module. Once the Test Plan has been approved the user needs to click on the "Start Test" button on the Test Request workflow section. The user will be redirected to the "Time Log" tab where you can set the downtime by selecting the Test Timer category and click on start test button.

The Test Request for which the facility downtime has been set will be reflected on the Calendar module, with "Red" color legend as seen below.

To add values to the Test Timer category the user needs to navigate to the Admin module > Lookup > Test Timer category tile. Click on the "Create Test Timer Category" button to add the name and select the category as Test Request or Test Facility. The values added here will get populated in the Test Timer category section of the Test Request module.
