STI-13520NB Universal Stopper Blue Horn Enclosure

Product Description

The Safety Technology International STI-13520NB is a universal stopper enclosure designed to protect horn devices and alert systems from tampering, vandalism, and accidental activation. Built for use in commercial and institutional settings, this enclosure fits over existing horn units to provide a physical barrier while still allowing the horn to function as intended. The blue color provides clear visual identification in facilities where color-coded safety equipment is required. This unit is sold individually and is typically installed by licensed electricians or fire alarm technicians.

The STI-13520NB is suited for commercial buildings, schools, hospitals, and industrial facilities where exit devices, push buttons, and audible alarm components require protection. It is commonly used in high-traffic areas where tampering or accidental activation is a concern. The enclosure integrates into existing alarm and notification systems without requiring major modifications to the mounted device.
