Clear polycarbonate dome cover, 9-3/8 inches wide, for horn or strobe protection

Safety Technology International

Safety Technology International STI-1219 Clear Polycarbonate Stopper Dome

SKU CH-496Y-2PEF3

Clear polycarbonate dome protects horn, speaker or strobe from vandalism and accidental damage

  • Clear polycarbonate shell shields strobes from vandalism
  • 150 dB alarm option deters intruders instantly
  • Weather-rated cover protects horns and speakers outdoors
  • Wide 9-3/8 inch diameter fits most devices
  • Durable polycarbonate resists impact and UV damage

Protective Stopper Dome

The Safety Technology International STI-1219 is a clear polycarbonate cover designed to shield horns, speakers and strobes from vandalism and accidental damage. Suitable for indoor and outdoor mounting, it protects alerting devices in commercial, industrial or public settings where equipment is exposed to tampering or impact.

Replaces Exposed Mountings

Upgrading from an unguarded device to this dome eliminates the risk of deliberate sabotage or knocks that disable critical signalling. The jump is worth it whenever a horn, speaker or strobe sits in a hallway, loading bay or exterior wall where damage would compromise safety systems or evacuation alerts.

Suits Facility Managers

This dome suits facility managers and installers who need a transparent, durable guard for existing notification appliances without adding an integrated alarm. Buyers who want a self-contained 150 dB alarm unit or a coloured cover for visual coding should look at something else.

Questions about this item

What width opening does the 9-3/8" polycarbonate dome need to cover a horn or strobe?

The clear dome measures 9-3/8 inches wide and fits over compatible horns, speakers or strobes to shield them from vandalism and accidental impact.

How is the STI-1219 stopper dome mounted to the wall or ceiling?

The cover installs over the device using the existing mounting hardware of the horn, speaker or strobe; the step often missed is ensuring the device is firmly secured before snapping the dome into place.

When should the clear polycarbonate cover be replaced?

Replace the dome if it becomes cracked, heavily scratched or yellowed, as damage reduces visibility of the strobe and weakens protection against vandalism.
