Agility PIR sensors insensitive

[Al Brown]

Hi forum.

 

I have a risc agility alarm. Took the movement sensors down to paint and have reinstalled. They work but are very insensitive you need to get right up to them to set them off.  Any ideas?

assuming you have not refitted them in funny way-

 

they sleep after movement

 

if old the lens might be going

 

battery's on the way out....

Thanks Mr Happy that’s helped.  I’ve realised it’s something to do with the fitting. When I take them down and prop them up on a shelf they work perfectly fixed with the supplies fixing they work but are insensitive.  The fixing is part of the back that keeps the tamper switch down.  Suspect the back is not fitting snugly when on the wall.  Any ideas?

Are the fairly directional? Could it be they are looking at the top 2 feet of the room space when fitted?

need to fitted vertical in the corner at the ceiling

Yep that’s where they are. I’ll experiment, thanks for the advice!
