This is done with a D5200 programmer. In the TEST REPORTS menu there are two prompts marked DAYS TIL RPT and HOURS TIL RPT. This is the amount of time in days and hours from the time the panel is programmed until the test report is sent to the central station. It’s based on the test report interval programmed into the panel for all subsequent test reports. If a copy of the program is received from the panel, these prompts will show zeroes, since this is a one time entry that can be over written. Re-enter prompts after programming panel. Resetting the panel using the reset pin will set these prompts back to zero requiring them to be programmed with the D5200.
