These virtually indestructible covers for the strobe stoppers (slotted for sounder/strobe unit) are specifically designed to prevent vandalism and accidental damage to a signal unit of a fire alarm system. The sounder / strobe stoppers are moulded in clear, thick UV stabilised polycarbonate material, the variety of spacers available can accommodate larger sounder/strobe units and retrofits – as well as weather resistance and surface mount applications.
