New siga-ps detector installed and show this message from SDU :

"Max. quiescent value threshold Optical sensor exceed - dirtied"

the siga-ps are new and totally clean. Anybody see this ?

i had the same problem, i replaced the detector, after an hour the trouble return on the same location, the problem maybe is not on the detector it may be on the wiring

just wait 24 hours, because the new detector receive the programming of the panel with data from the old detector
