I have a DSC Bravo 3 motion sensor. I had to take it down to relocate it. In it’s new position it is detecting motion and lighting up but when I try to reenable it on my alarm panel, it tells me that the sensor is “open/activated”.

When I put it back together there was a small resistor and spring that didn’t go back in. I assume these are important and are causing this issue. Can anyone help identify where both need to go?
