The Siren is a retro-futuristic alarm device with a cylindrical metal body, featuring a ribbed surface for grip and a domed top housing the sound emitter. The body is painted in a faded yellow with chipped paint revealing rusted metal beneath, indicating its weathered state in the post-apocalyptic world. A series of small, circular vents are evenly spaced around the midsection, and the base has a sturdy mounting bracket for fixed installation.
