I forgot they tried to be clever and called them tri techs they are the ones, follow the instructions they will be absolutely fine. I had a big dog jumping around on a bed to get snacks I had thrown on there. They are the best pet tolerant detector available
They are fine so long as you install them correctly, the animal must not be able to get within six foot of the detector, dont point them at stairs, I have hundred of them out there with no problems at all
