STI’s first product came directly at the request of a high school principal in Detroit, Michigan who had problems with false alarms. That led Jack Taylor to invent the Stopper Pull Station Protector. Taylor then founded STI. That was over 25 years ago. Today, Safety Technology Incorporated (STI) now markets more than 40 unique products throughout the world to help prevent false alarms, plus theft and vandalism of smoke detectors and fire extinguishers. Susquenita School District Buildings and Grounds Director Robert Finnen testifies to STI’s products, “Our STI Stopper II units have prevented after-school activity kids from pulling false fire alarms. If kids attempt to open the cover, the warning horn stops them from any further attempts.” STI is based in Waterford, Michigan with an office in Worcestershire, England.
