The Bogen VRS3 is a vandal-resistant speaker designed for hands-free two-way communications. The VRS3 consists of a 3-inch, weather-resistant, cone-type speaker and a 25V transformer (tapped at 0.25, 0.5, and 1W). The transformer can also be bypassed for 8-ohm operation. The speaker and transformer are mounted on a 12-gauge stainless steel faceplate. The speaker is protected from harm by the faceplate, and three (3) interwoven steel screens. The VRS3 includes a heavy-duty metal push button switch that protrudes slightly from the faceplate and can be used to initiate a call to a control center. The switch can be wired for use with systems that require a momentary contact closure for call annunciation.
