Wifi motion sensors

Our house had a wired alar, system in it when we bought it.  Telus used the wired door sensors through a "translator" but didn't (or couldn't?) do the same for the wired motion sensors so they installed wifi ones.
I have 2 shops both with wifi motion sensors; is there a way they can program the motion sensors to be active when we set the alarm to "arm stay" so the alarm will still go off if someone breaks in through a window?
