STI Horn/Strobe & Strobe Damage Stopper® Series – Polycarbonate Protective Covers

The STI Horn/Strobe & Strobe Damage Stopper® Series offers virtually indestructible protective covers for notification appliances, designed to prevent vandalism, accidental damage, and misuse. Each cover is molded from thick, clear UV-stabilized polycarbonate, providing rugged protection while ensuring devices remain fully visible and accessible for service.
Models for horn/strobe combinations feature slotted covers to allow alarm sounds to be heard clearly, while strobe-only models have solid covers for maximum lens protection. With multiple spacers and back box options—including enclosed boxes, conduit knockouts, and flush-mount frames—the Damage Stopper line adapts to standard, retrofit, surface-mount, and even weather-resistant applications.

Key Features

  • Maintains clear visibility of horn/strobe and strobe-only devices while providing protection.
  • Backed by a three-year guarantee against breakage of the polycarbonate cover in normal use.
  • Available with multiple spacer depths and mounting configurations to fit various applications.
  • Slotted covers (for horn/strobe models) allow sound to pass clearly without obstruction.
  • Solid covers (for strobe-only models) offer maximum protection for lenses.
  • Made of clear, UV-stabilized polycarbonate for impact resistance and long-term clarity.
  • Withstands extreme environmental conditions: -40°F to 250°F (-40°C to 121°C).
  • Spacers A–E accommodate enclosed back boxes, conduit knockouts, and flush-mount setups.
  • Enviro Kits available for harsh or damp conditions.
