Emerson Automation Solutions has announced the availability of the Appleton HEX series LED Hazardous Location Exit Sign, rated for C1D2- areas
The signs are specifically designed to provide bright and reliable emergency illumination during a crisis involving loss of power, as well as to perform as standard signage marking escape routes and exits in hostile industrial environments, such as oil refineries, underground tunnels, wastewater treatment centres and other facilities where flammable gases and vapours are present.
Appleton HEX series LED Hazardous Location Exit Signs are set to come prewired for fast installation, offer 6 kV of surge protection as standard and are dual voltage to run at 120V or 277V. Equipped with a 4.8V rechargeable nickel-cadmium battery, the signs provide failsafe emergency operation for 90 minutes or more upon loss of AC power. Self-diagnostic circuitry tests operational conditions monthly, bi-annually or annually. In case of failure detection, the visual status on the LED indicator lights up immediately to alert plant maintenance to perform repairs. Diagnostics testing can also be prompted on-demand using the included magnet flash.
According to Emerson, LED technology in the present times is ideal for Appleton HEX series LED Hazardous Location Exit Signs and the capacity to achieve years of maintenance-free operation, LEDs promise unparalleled energy efficiency to achieve a far lower cost of operation compared to typical self-illuminated exit markers.
Additionally, LEDs do not use glass enclosures or filaments and are therefore resistant to vibration and impact from heavy machinery. In industrial facilities subject to fluctuations in ambient temperatures, LEDs perform better than traditional lighting sources since this technology creates little heat and performs even at temperatures well below freezing. By leveraging LEDs, Appleton HEX series LED Hazardous Location Exit Signs aims to provide the necessary brightness to be visible through smoke, darkness and fog to give workers greater situational awareness when identifying the location of exits.
Appleton HEX series LED Hazardous Location Exit Signs are UL listed for use in class-I, Div. 2 (C1D2) applications and in wet locations. Walkways, exit ramps, stairs and aisles are typical installation locations.
