The SAFETY TECHNOLOGY INT'L INC STI-6518-FR is a protective cover designed to fit over manual fire alarm pull stations. Known in the field as a Bopper Stopper, this cover helps prevent accidental or unauthorized activation of the pull station while keeping the device accessible in a genuine emergency. It is a component in commercial and institutional fire alarm systems and is typically installed by licensed fire alarm technicians or electricians performing life-safety work. The French-language labeling makes it suitable for installations in French-speaking regions or bilingual facilities where code or building requirements call for French signage.
This cover is used in commercial buildings, schools, healthcare facilities, and other occupancies where pull station vandalism or accidental activation is a concern. The French labeling variant is appropriate for facilities in Quebec, bilingual Canadian properties, or any site where French-language fire safety signage is required by local authority having jurisdiction. It is sold as a single unit and fits into the pull station cover category of fire alarm accessories.
Designed as an OEM-style replacement or new-installation cover for manual fire alarm pull stations in commercial life-safety systems. Verify dimensional fitment against the installed pull station before ordering.
Installation should be performed by a licensed fire alarm technician or electrician qualified in life-safety systems. Before installing or servicing the pull station or its cover, notify the monitoring station and follow the facility lockout procedure to avoid a false alarm dispatch. Ensure the installed cover does not obstruct the pull station mechanism or violate local fire code accessibility requirements. Consult the authority having jurisdiction to confirm French-labeling requirements are met for the specific installation.
