Transmitter and receiver module for alarm

[upup]

Hi, I have a carport and want to put a pir there, but want you get a transmitter and receiver module to give me a contact in the house. The distance is not far, but I don't want to hang a cable for it.
I do have an ids alarm, but my wireless zones is full. It is a 64, it got 3.

The pir needs to connect wireless to the alarm system. But at the alarm system is a contact normal zone. I basically want a module to do just that.
