DSC 1555 - smoke detector replacement

I am trying to replace the ceiling mounted smoke detector on my PC 1555 panel. I have attached three pictures of the existing wiring. Any suggestions.

To a certain extent, you actually zoomed in a little too much. Based on what's visible, it looks like someone installed a 4 wire smoke, and used the junction box for a 120v hardwired smoke as the mounting location (technically a little sketchy, code wise).

In any case, you can replace it with any standard 4 wire smoke. I recommend the System Sensor 4-WB.
