My ES has a Thatcham Cat 1 alarm, so has two sensors in the car near the courtesy lights at the front. It works, too.
Lock your car with a window open, then try to open the door from the inside (as a car theif might try). That should set the alarm off.
I left my wondow open with the car locked in the summer for a few minutes before getting in to get the hot air out. I threw in a bottle of water and my CD wallet, and triggered the sensors.
To test, just putting yor arm in an open window is enough to set the alarm off if you have sensors.
