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.

Optically efficient notification device for use in life safety wall strobe applications

A ceiling notification device has a housing; a reflector unit mounted to the housing; a lens positioned over the reflector unit; and a lamp in the center of the reflector unit along the central axis. The reflector unit has a base, a plurality of reflective fins, and a surface portion. The base has a curved surface that is symmetrical about a central axis. The plurality of reflective fins each has a first fin portion extending from the base and a second fin portion extending from the base and the first fin portion, the second fin portion having an inner surface and an outer surface, wherein the inner surface is exposed to the central axis. The surface portion extends from the base and positioned between the first fin portion and an edge of the base and is angled toward an inner surface of the second fin portion.
