We live in Spain and are looking to buy an Ajax alarm system but want to add a 180° motion detector. We do not want the curtain. We would like to buy an Optex motion detector with Ajax transmitter.

Can you tell me which Optex motion detector is compatible with the Ajax transmitter please? WXI-R or WXI-RAM. Also if we were to buyan Optex detector with a different transmitter, could this transmitter be removed and we use the Ajax transmitter?

The customer may purchase any of these models.

Then add Ajax RF transmitter.
