Electric buzzers for 12V and 24V electrical systems designed primarily for operation in conjunction with low-pressure warning switches have been introduced by Intertruck, Fixed in the cab by a single screw, they have no moving parts; there is no disturbance to other instruments in the cab and no sparking.
The buzzers are approximately 1-tin. high and 14.in. diameter and are continuously rated. Current consumption is negligible.
It is, says the company, a simple matter to connect buzzers to switches on shutters, tailgates or cab doors so that an audible warning — inside or outside the cab — indicates that the vehicle is being tampered with. Price: £1 .35.
