Hi. I have a powemax plus system with various Pet PIR's (NEXT K985) however after 9months one is causing me problems.
I'm the last few weeks it has started complaining of a "low battery". I've changed the battery (although it's meant to last 4 years and only done 9months) with a new one and after a day it started giving the same warning.
I've since swapped the battery with another sensor that doesn't give any warnings and again after a day the warnings started from the same sensor.
Can anyone suggest what to do? It's apparent it's not the battery an I have had to disable the warning beeps as it is driving me nuts.
If I take the cover off the sensor and them replace it immediately the alarm stops sending te low battery warning, but in the morning when I wake up it is back to telling me to "check system for trouble".
