The STI STI-6518 is a clear polycarbonate cover for manual fire alarm pull stations, fitted with a spring-loaded hinge for quick emergency access. The cover sits over the existing pull station. As a result, it shields the device from accidental bumps and unauthorized activation while keeping it fully visible.
STI calls this product line the “Stopper” cover. First, the technician mounts the cover over the pull station. Then, in an actual emergency, a single motion lifts the hinged shield and exposes the pull lever. Therefore, the protective layer does not slow down legitimate alarm activation.
Where the STI STI-6518 Fits Best
Nuisance pull station activations are a common headache in schools, multifamily housing, hospitals, and public buildings. In addition, accidental bumps from carts, equipment, or moving furniture trigger costly false alarms. The STI-6518 reduces both. However, the cover does not replace any code-required signage or training; it complements them.
The clear polycarbonate body lets occupants see the pull station and its instructional label. Specifically, the cover is designed not to obscure the device it protects.
