you changed the pcb but did you look for any large spiders behind the casing?

if you want to prove environmental or system problem then obscure the pir with a thick cardboard box and wait a week, no alarms problem is likely enviorement, obviously inform your client and get it signed for before doing this.

as this is the 2nd pcb have you tested the battery properly also the panel voltage on a prolonged mains power down at the aux terminals? is there any sign in the log or a power cut (mains powered clocks on cookers and the like can be a clue) have a real close look at the aux power connections in the panel/psu,

make sure all the aux cables are tight and held properly in the connector - oh! and just shoot any cats you see, and if they twitch shoot them again .
