Two of my PIR sensors are not pet safe so the alarm is kinda useless. I purchased two Paradox pet safe sensors but it seems that the wiring is different. (or just the names of the connections) Do you think that I can replace the old sensor with the new one - how would I wire it?

I must say that I have no idea what the resistor is all about - maybe you can shed some light on that too.
