Will pets set of my alarm?

Pets can cause false activations. The motion detection PIR is pet immune up to 35kg. Also, windows and doors are fitted with inertia sensors that will activate the alarm upon vibrations and impulses from contact. However there is flexibility in the system whereby the inertia sensors have been engineered to activate under specific criteria, thus minimizing the amount of activations to pet activity. If the system is wireless the PIR is not pet immune.
