The Edwards 125 Class XBR XTRA-BRITE™ LED beacons are UL and cUL Listed dual mode signaling devices, available in two versions, Steady-On/Flashing (125XBRM) and Steady-On/Lightburst (125XBRZ). Both versions feature a corrosion-resistant Type 4X enclosure and can be panel or conduit mounted. The base is manufactured from a 33% glass filled nylon, providing high-resistance to heat and high chemical resistivity. The lens is made of shatter-resistance polycarbonate. Both the Steady-On/Flashing LED and Steady-On/Lightburst LED beacons are available with either a black or gray base and amber, blue, green, red or white lens. Both the 125XBRM and 125XBRZ beacons are dual mode devices, maximizing application flexibility while reducing inventory costs. The 125XBRM beacons ship from the factory in Steady-On mode, with the built-in option of switching to flashing mode (65 fpm) through an additional wire connection. The 125XBRZ beacon ships in Steady-On mode and when ultra visibility is critical to the application, can be easily switched to Lightburst mode. The 125 Class XBR LED beacon is supplied with a double threaded - 1/2 in internal and 3/4 in external - conduit hub which can be mounted into an approved conduit box. It can also be panel-mounted using the mounting gasket provided with the unit. When panel mounting the 125 Class Strobe, the surface and construction details of the panel must be taken into consideration to insure the integrity of the outdoor, NEMA 4X rating is fully maintained.
