Pet Proof PIR's

Hi,

I am currently planning the CBus installation for my selfbuild. I am looking to use PIR's in a number of locations (such as utility area) rather than switches. We will be using a combination of 5753L's and 5753PEIRL's. The data sheet does not say if these are pet proof and as we have a cat I was wondering if she will be setting them off?

Whils't I'm not sure how the 5753L and 5753PEIRL would perform under "pet conditions" the 5753PEIRL does have a sensitivity adjustment. One of the pots can be configured to adjust the sensitivity. All you would need to do is reduce it until the cat doesn't false trigger it. Bear in mind that you will be reducing your maximum detection range at the same time.

Only the 5753PEIRL has this feature, the 5753L does not.

 

I cant speak much for the C-Bus PIR sensors and thier pet immunity. As a rule Pet immunity is a tricky area and very much hit and miss. Moreso with Cats.

Dogs are generally happy with just walking around the floor and not really jumping on counters etc. Cats love to jump on counters, chairs,tables anything close by. Very hard to mask or adjust PIR's when you have no idea where they can/will jump.

Generally the only way to have pet immunity is to keep them out of the house.
Like Newman suggested you can adjust them right down but that may cause them to not sense small humans

Unfortunately you may have to put up with a certain amount of false triggering by pets if you let them wander around your house.

Fortunately the cat is getting quite old, so don't jump around much. Problem is then when she shuffle's off her mortal coil the kids will probably want some kittens.

How would you mask the PIR? One option for me would be to mount the PIR horizontally in the wall and mask off the lower half, so not be triggered by anything on the floor.

 

You might be able to paint the cat in thermal resistive paint, probably available from an army surplus store.

 

These guys have some great non toxic (read cat applicable) heat resistive paint complete with MDS sheets for the Vet if required.

 

Can explain this to my wife please - I'm too shared

Is any way its be attached to Bus Coupler?

 

I just prefer to think of my cats as random program for the sensor lights, a handy security feature

 

Aluminium foil is a fairly effective reflector of IR

... ummm, what about asbestos wrapping ?
