STI (STI-13020FR) Universal stopper dome cover w/fl mt, horn, red housing, fire label

The STI STI-13020FR is a Universal Stopper dome cover for manual pull stations. It has a red housing, an integrated horn, a fire-label, and a flush-mount design.

The cover guards a manual fire alarm pull station against accidental or nuisance activation. When the cover is lifted, the integrated horn sounds a local warning. As a result, occupants are alerted before the pull station itself is engaged.

Typical Applications

Schools, hospitals, and office buildings often install Stopper covers in high-traffic corridors. For example, locations with frequent false alarms benefit most. Therefore, the STI-13020FR helps reduce nuisance pulls while keeping the station fully accessible in a real emergency.

Key Features

• Universal Stopper dome cover compatible with most standard pull stations
• Red polycarbonate housing with fire-alarm label
• Built-in horn that sounds when the cover is lifted
• Flush-mount design for a clean installation against the wall
• Does not block the pull station’s normal operation

Notes on Compatibility

The STI-13020FR fits most single-action and dual-action pull stations. However, station-specific dimensions vary by manufacturer. Furthermore, confirm pull station size and mounting depth before installing on a non-standard or shrouded pull station.
