I think it takes 24 hours for the environmental compensation to reset.
How to Determine when a Photo Detector is dirty– EST3:
If you use SIGA-PS, SIGA-IPHS, or SIGA-PHS the EST3 system will display ”Device Maintenance Alert” (0675 Loop 1 or 0685 Loop 2) condition at the 3-LCD/3-CPU(1) when the Photo portion of detector needs maintenance. Running a report for “Dirty Head List” will generate a list of all devices and their dirty levels.
If you use SIGA-PRO to update the maintenance date after detector cleaning the monitor alert go out immediately (if it's not help you should restart the Panel to update detectors status).
