This multi-purpose large combination IP65 emergency bulkhead light and exit sign comes with an environmentally friendly long-life battery with a 3-hour duration during loss of supply. Internal jumpers allow the installer to select 1-hour or 3-hour operation from the internal battery. In 3-hour mode the open area optic LED lamps provide the standard illumination of 184 lumens, whilst in 1-hour mode the LED lamps provide 414 lumens. The 1-hour high output mode make it suitable for use in high risk areas such as kitchens, plant rooms and industrial areas where devices need to be shut down before safe exit from the area. The included legend enables the ONTEC S30 to be used as an exit sign with up, down, left and right arrow directions and a 30 metre viewing distance. Due to the injection moulded polyurethane gasket, the IP65 rated ONTEC S30 is perfectly suited for industrial or outdoor areas.
