The image shows a set of four red fire hydrants mounted on a gray concrete wall. On the left side of the wall, there is a red fire hydrant with the words "Grinnell Sprinkler Alarm" written on it in white letters. Next to it, there are two red fire extinguishers and a yellow metal bracket. The wall appears to be old and weathered, with some cracks and chips visible on the surface. The overall color scheme of the image is red and yellow.
