The Bogen VRS1 and VRS2 are vandal-resistant speakers designed for hands-free two-way communications. The VRS1 and VRS2 each 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). The VRS1 and VRS2 each have a 5-1/2" W x 7-3/4" H faceplate and should be mounted to a 2-1/2" deep dual-gang box (4-1/2" W x 6-13/16" H), such as the Thomas & Betts Model H2BD-3/4 & 1 or equivalent.
