Sentry Siren was founded as the Interstate Machine Products Company of Rochester, New York in the very early 20th century. The company would later rename itself to the Sterling Siren Fire Alarm Company in 1925. The company began producing sirens in 1905, producing small scale vehicular sirens, before beginning large scale siren production with the Model M series of sirens beginning in 1912, designed by Merton C. Armstrong. The Model M was used in fire warning, air-raid warning, and disaster warning and ended production in the 1980s to make way for a new line of sirens. The units were noted for their durability, with close to 1000 Model Ms being known to stand as of 2024; an estimated half of them still in service.[1] Today, Model M units are considered collectibles by siren enthusiasts, due to rising rarity and simplicity to restore. Some other products that Sterling Siren produced were the "Little Giant", and the famous "Free-Rolling" and "Sirenlite" series of fire engine sirens.
