Question: The provided images include the fire pump and its data plate, as well as some pictures of the solenoids; however, the images do not clearly show what the solenoids are connected to. Based on the available information, we are assuming these are solenoids for the fire pump controllers.

Answer: These solenoids are for the pre-action system.
