Here are a couple of pics of a Simplex 4010ES I saw on the jobsite I worked on today. I didn’t install this one, our company was there doing the Data cabling and I was helping that crew. I also got an ‘under the hood’ picture as well, sloppy wiring and all. I never thought I would have seen one of these in my area.
The main interface does not have raised buttons like the 4100U or ES does, it has the flat style buttons like the 4100 did. The display is attached to the dress panel door, and the outer door is plastic now. The vertical card with the cat5 (blue cable that originates from the top conduit entry) leads attached to it is the dialer. It is a small board in a giant backbox. The system had a supervisory active on a duct detector, and a trouble from the same device.
