The Bogen VRS1 is vandal-resistant speaker designed for hands-free two-way communications. The VRS1 consist of a 3-inch, weather- resistant, cone-type speaker and a 25V transformer (tapped at 1/2 watt). The transformer can be bypassed for 8-ohm operation. The speaker and transformer are mounted on a #11-gauge stainless steel faceplate. The speaker is protected from harm by the faceplate, a baffle plate with stamped perforations, and a grille screen.The VRS1 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 (e.g., MULTICOM 2000), and includes a silicone-controlled rectifier circuit for use with systems that require “latching” operation (e.g., Multi-Graphic).
