A vertical 2:3 low-poly gray 3D model render of a fire alarm pull station device, on a neutral light gray background, no people. The rectangular backplate is matte gray with visible triangular facets and wireframe-like shading. At the top are raised uppercase words FIRE and ALARM, with a circular knob or indicator component between them featuring concentric rings and radial spokes. The middle has a recessed area with a wide horizontal bar labeled PULL DOWN in raised letters and a downward arrow below the center. At the bottom is raised text HOTRESCUE.
