Stayco warning buzzers have been developed primarily for cab interiors and are of the vibrating hammer type.  The lower frequency of these buzzers is much more tolerable to the ear than cheaper piezoelectric alternatives.  This reduces the risk of the buzzer being permanently disconnected by an annoyed driver and the consequential hazard of un-warned danger.  They can be supplied as continuous or intermittent sounding versions in 12 or 24 volt.  We strongly recommend fitting intermittent buzzers when the warning has to be sounded for more than one or two seconds at a time.
