A Brief History...

Fred Harrington founded the company in 1928 with the introduction of a fire alarm reporting system known as a Coded Municipal Master Box system. This system is still in use today in several major cities and military bases. Harrington’s innovations forged the development of municipal fire alarm and traffic signal systems, which were quickly accepted nationwide.

In the early 1970's, Harrington expanded with the introduction of conventional local non-coded Fire Alarm Control Panels and Peripheral Devices. These systems have evolved into today's complete line of both solid state and sophisticated microprocessor-based conventional fire alarm system's equipment.
     Harrington Signal introduced the Multiplex Base Loop Reporting system in the late 1970's. Due to its high reliability and level of performance, many of these systems are still in use today along with Wireless (radio) and DACT (digital alarm communicator transmission) communication technologies.

The Harrington line of Addressable Fire Alarm Systems was released in 1980. These evolving, microprocessor-based "state of the art smart" systems are among the most advanced and reliable in the industry today.
     Harrington Signal was purchased from Fred Harrington’s descendants, in 1993 by well known Midwest industrialist Roy Carver, Jr., who made and continues to make strategic investments in Harrington Signal, which keeps us at the fore front of technology.


Today Harrington Signal Inc offers a complete line of ISO-9001:2008 Certified quality manufactured products.
