Qolsys Sensors

What is difference between Qolsys IQ QS1133 and 1135 sensors? For example, does one have a greater signal range.

I don’t recall us ever carrying the 1133 model, it is a larger sensor, I’ve always seen the range specs given as identical to other S-Line sensors, but I believe it has a larger antenna and may perform better on a metal door if range is an issue.
