KEMP, Texas, May 1, 2013 /PRNewswire/ — Larson Electronics has announced the release of an explosion LED exit sign designed to provide a reliable and well illuminated exit indicator capable of operating independently of external power sources during power failures. The EXP-EMG-EXT-12W-1LX Explosion Proof Emergency Exit Sign operates the same as a standard exit way marker under normal conditions, but with a built in battery backup system and automatic current sensing circuitry will provide 90 minutes of operation when power is interrupted.


The Larson Electronics EXP-EMG-EXT-12W-1LX explosion proof emergency exit sign  is a rugged and reliable exit indicator which features explosion proof approval and failsafe operation in the event of power failures. This emergency backup power equipped exit sign is designed to act as a standard exit indicator in hazardous locations under normal operating conditions, but if power is interrupted, such as during blackouts or plant wide power failures, the unit automatically switches to an internal battery backup system which provides continued operation for up to 90 minutes. The battery backup system on this explosion proof exit sign includes an internal Nickel-Cadmium with a 7 to 10 year operational life and a built in charging system which maintains the battery at a ready state. The fixture is constructed of copper free aluminum for light weight and high durability and has been powder coated to provide resistance to corrosion. The high visibility exit sign is a three sided design that is illuminated by a single 10 watt LED lamp. This LED light has a 50,000 hour operational life and produces more light than a comparable 100 watt incandescent bulb while using only a tenth as much current. This LED lamp also runs much cooler, and can withstand extremes of temperature and impacts and vibrations that would cause ordinary incandescent and fluorescent lamps to fail. The entire housing is IP67 rated waterproof for resistance to wet conditions and designed to be easily mounted to flat surfaces such as walls. This explosion proof light can run from universal voltages ranging from 110 to 277 VAC, making it extremely versatile and easy to install in a variety of locations. This explosion proof exit sign also meets NFPA101 (Life Safety Code), UL844 and UL924 compliance, and is ideal for hazardous locations where operators require the security of fail safe operation combined with the reliability and effectiveness of LED lighting technology.

“During power outages, this explosion proof led light illuminates the light heads and exit sign for 90 minutes, clearly identifying exit locations to all occupants in case of emergency,” said Robert Bresnahan of Larson Electronics LLC “The ability to automatically switch from normal power of 120V to 277V AC to battery back-up in hazardous areas during power outages is a design fit for any hazardous location.”
