Ajax StreetSiren Dummy Box White Decoy Siren Housing 20473W

A dummy siren box provides a visual deterrence element without any electrical function: the exterior of the building appears to have multiple alarm sounders, which from the perspective of a potential intruder surveying the property, signals a more heavily protected site. Research on burglary deterrence consistently identifies the visible presence of alarm equipment as a significant factor in target selection, and multiple sounder positions reinforce this signal.

The Ajax dummy box matches the housing design and finish of the genuine Ajax StreetSiren, maintaining a consistent appearance across real and dummy units on the same installation. A mix of mismatched dummy and real sounders reduces the visual consistency of the installation and makes the dummy units more identifiable as non-functional.

Dummy boxes are particularly useful at positions that would benefit visually from a siren housing but where running a cable to a fully functional unit would be difficult, expensive, or disproportionate to the security benefit of an additional functional sounder at that specific position.

The white finish suits standard UK building exteriors with white fascia boards, UPVC cladding, and rendered surfaces.

For Ajax alarm installers completing building exterior alarm visual deterrence on residential and commercial properties across London and the UK where additional dummy siren positions are part of the design, the Ajax StreetSiren Dummy Box white provides the correct matching appearance housing.
