Sentry Siren, Inc. has been manufacturing the world’s premium warning sirens since 1905. Formerly Sterling Siren and Fire Alarm, the company started manufacturing the famous Model M-Series warning sirens in the late 1910s and early 1920s. These sturdy units saw widespread use in many applications including Fire Departments, air raid sirens, and basic calamity warnings. The last Model M was produced in the late 1980s. These “M’s” are still respected and sought after even today. Additionally, A model M-5 produced in 1917 is still in use today by the Manchester, Michigan Fire Department. That’s right, over 90 years of use. Sterling also produced numerous Fire Truck sirens, smaller industrial sirens, call boxes, and for a short time, they even made washing machines.

Sterling transferred from Rochester, NY to Canon City, CO in 1972 and renamed Sentry Siren, Inc. Sentry continues to operate in the majestic Colorado Rockies. Driven by a desire to produce the best performing, highest quality, and most reliable sirens available, each Sentry Siren is hand-built to grueling standards. As the designer and creator of the world’s finest warning sirens, we pride ourselves on our outstanding workmanship, unparalleled customer service, and bullet-proof dependability.

We are the only business to use fan-cooled, industrial quality, continuous duty motors, for the ultimate in reliability. We are the only business that uses siren controllers that are field programmable and field serviceable and USER adaptable. Therefore, if service is essential, a competent transportable service operator can deal with the unit in the field, averting service disruption. Moreover, if a simple modification to the unit is needed, basic functions can be attuned by the user avoiding the need for a service call. Sentry Siren will work with your resident service specialist to ensure any maintenances are completed swiftly and appropriately.

With our five-year, 100% parts and labor guarantee, you can be confident that your system will be efficient at all times. There are also lightning arrestors available on all sirens. We employ “Single Ingot Sampling” methods when creating our rotors and stators to ensure even enlargement and shrinkage of the Siren’s internal workings. This procedure ensures a siren’s performance will not reduce over time like those of our competitors. Sound projection from our sirens are multi-directional: Full decibel yield in all directions at all times.

We are as close as your phone. With a toll-free number, you will talk straight with the manufacturer; no misinformed salespersons, no red tape. Additionally, we have sales representatives all over the U.S. who are accessible to support you through any problems. Sentry Sirens are manufactured for a minimum of 25 years of worry-free use, but typically see 40+ years of service.

Regarding life anticipation, we estimate this worth based on the assessments our motors and bearings transmit, as well as real-world testing and experience. The motors used in our AC and DC sirens are custom built for each specific siren. We did not take the “easy road” and use a store-bought motor to achieve the task of driving our quality sirens. Our motor/bearing blend has the capability to provide 10,000 hours of exertion before requiring service. To explicate just how long that is: given a typical 3-minute activation, this likens to 200,000 activations. Based on a weekly assessment with an average number of emergencies, your siren’s motor would need checking after 2,500 years. That’s a pretty long life.
