Sentry Siren, Inc. has been producing the worlds finest warning sirens since 1905. Formerly Sterling Siren and Fire Alarm, the company began production of the famous Model M-Series warning sirens in the late 1920's and early 1930's. These durable units saw extensive use in many applications including Fire Departments, air raid sirens, and basic disaster warning. The last Model M was produced in the late 1980's. These "M's" are still revered and sought after even today.

Sterling also produced numerous Fire Truck sirens, smaller industrial sirens, call boxes, and for a short time they even made washing machines.

Sterling was moved from Rochester, NY to Canon City, CO in 1972 and continues to operate in the majestic Colorado Rockies.

Motivated by a desire to produce the best performing, highest quality, and most reliable sirens available, each Sentry Siren is hand built to exhausting standards.
