STI - About Us


STI Waterford 2005


STI is a family owned and operated business that began thirty years ago with Jack Taylor's invention of the Stopper Pull Station Protector. Safety Technology now markets more than 1000 products throughout the world. These products help prevent false fire alarms, theft and vandalism of the things that protect us all.

Headquartered in Waterford, Michigan with an office in Redditch, Worcestershire, England, team STI works hard to continue the work Jack Taylor started. Our first product came directly at the request of a customer, Garnett Hegeman: a high school principal in Detroit, Michigan who had a problem with false fire alarms. Most new products are a direct result of these types of requests. If you have a false fire alarm, theft, vandalism or other problem, we invite you to contact us with the challenge of solving it for you.

STI Products Work!
Since we installed the STI Exit Stopper, there are no more unwanted exits from the gym door. It stopped dirt from being tracked back on the floor.
