Safety Technology International

One of our products, Stopper II® Contractor Packs, is a protective cover multipack. It includes six complete covers in one package. Each time-tested protective polycarbonate cover mounts directly to the wall over an existing pull station, helping to prevent false fire alarms (without restricting legitimate use), while guarding against vandalism and accidental damage. The power source for this device is a 9V DC alkaline battery, which also includes the battery. When covering a pull station outside, UL safety standards also require stations to be listed for outdoor use. It is important to know that typical working properties of polycarbonate are -40° to 250°F (-40° to 121°C). Installation is quick and easy for this product series.
