Wet location exit signs are suitable in most outdoor locations, but there is always the remote possibility of a small factory defect such as a gasket fissure, that could jeopardize these signs in extreme weather. To insure your investment as well as appease the building inspector, have your location sign NEMA certified.
NEMA does not test these units, but instead lays out the testing guidelines in their NEMA 250 standards manual. The exit sign manufacturer will either conduct these tests or send the unit to a licensed third-party facility. Only after it has passed a number of harsh weather simulations, including a 200 hour salt spray down, can an fixture earn the title 'NEMA 4X exit sign.'
NEMA 4X exit signs look almost identical to thermoplastic models but are applicable across a wide range of locations including:
The N4X-X series is built with a durable polyvinyl chloride body that will not dent, peel, rust or corrode. A clear vandal-resistant polycarbonate lens is placed over the 'exit' face and is lined with a gasket that, when fastened to the housing, creates a watertight enclosure around the internal electronic components.
5-year warranty on the exit sign; 5 year pro-rated warranty for the battery.
Housing and Face Colors - there are many combinations of finishes for the exit sign face and body.
Face Styles - select single or double-sided styles.
Canopy Pendant Mount - for overhead installation between the skeleton of an awning.
Battery Heater - ideal for unit's placed in locations with temperatures below 20° F.
