Hi All, I am new on this board and am looking for some help. I bought the yale 6400 alarm system and installed myself. The problem I have is that the PIR sensors do not always work. When tested in walk test some times they work and sometimes they dont, its the same in alarm mode. Once I push the little test button on the front they always work on test after this. They are set to the alarm control panel ok.
Any ideas??????
