PeterM Posted January 26, 2011 Author Posted January 26, 2011 Hi guys, Thanks for the replies and healthy debate on the merits of a cat! Yes, it's a cat. At least the dog goes in it's crate...... Engineers code not a problem, I have it, and a manual which seems to be an installers guide as it gives a lot of info about location and zone setting but little technical info like requirements of PIRs! One sensor does look at the stairs, I was hoping that the pet friendly would cope with that? Leaping onto furniture is a worry, he does enjoy that. I notice that some sensors list different Hertz ratings, do I need to worry about that? Peter
