The Edwards Signaling 107XBR Series hazardous location XTRA-BRITE™ LED visual signals are NEMA Type 3R and Type 4 heavy-duty visual signals designed for indoor or outdoor applications. The units are available in 24 VDC or 120 VAC and are field configurable for steady-on or flashing (65 fpm). The inner, double fresnel lens is made of a high grade polycarbonate and is designed to magnify the super-bright LEDs inside. A clear, outer, impact-resistant glass globe also covers the lens and an optional dome guard fits over the glass dome to protect it against accidental impacts with machinery or falling objects. The 107XBR has three different mounting configurations including the pendant mount, bracket mount and ceiling mount and can be mounted on 3/4″ NPT threaded conduit. The 107XBR is designed for applications such as petroleum refineries, utility gas plants, dry cleaning plants, fuel servicing areas and other similar applications.
