What’s the difference between an DSC RF5132-433 and a DSC TR5164-433?
There are two major differences between the two devices. The first is the number of zones that each can handle. The RF5132-433 can do up to 32 wireless zones while the TR5164-433 can do up to 60 zones. The second is that the TR5164-433 is a transceiver instead of just a receiver: it can send signals as well as receive signals. This gives it access to some two-way wireless devices such as the WT5500 wireless keypad and the WT4989 wireless key.
