TPMS and all 4 tires losing air at the same rate

Not sure of the threshold where the warning will go off but if all 4 tires lose equal amounts of air then the warning never comes on. I was down 2 lbs in each tire and the warning didn't come on. What is the amount of air that a tire has to lose to set off the warning? And if all 4 tires get to that level at the same time will the TPMS warning system go off?
