Abstract:
A wall notification device described herein can draw a lower current by providing a more efficient reflector configuration. The reflector is designed to be positioned on a wall and provide sufficient light output in each of the requisite directions, as required by the UL 1971 standard. The notification device has a reflector unit having a base having a curved portion centered on the vertical axis and a flat portion extending from the curved portion; a reflective flange extending from a location near a top side of the base; a first and second specular protrusion extending from the curved portion of the base; a third and fourth specular protrusion extending from the base; a fifth and sixth specular protrusion extending from the curved portion of the base; and a sixth and seventh specular protrusion extending form the flat portion of the base.
