Can anyone direct me to relevant advice notes or personally advise as to the minimum stagger required for bleep and sweep to operate. We have a site at which the units have been deactivated in the central reserve, I am told they were confusing the users. I have not previously had any involvement with this facility but understood that the sound was directional but obviously there are still limitations. Can anyone offer any advice or personnel experience which may help ? I have a militant blind group insisting on the reactivation of these units whatever the cost. ******************************************************************************** Note: We are a Microsoft Office site.
