GRI Vent switch

has anybody used this in your installs? It's wired-only and the company says I have to use a wireless transmitter with it. Can anybody give me a link to one I could use which would connect to the vent switchs' terminal?

It sounds like you are asking for a wireless transmitter with external contacts that can be connected to the vent switch.  The wireless transmitter you choose will need to be compatible with your alarm system's wireless receiver.  Two popular systems are the Honeywell/Ademco 5800 series and the GE/Interlogix Crystal/SAW Wireless system.
 
Do you know what kind of wireless system you have?

Are you installing your own, working with a prewired system or what?
 
There's other ways to vent windows that don't require specialized hardware.
