Emergency signage and lighting products include emergency exit signs, bulkhead lights, LED emergency lighting units, and emergency spotlight fixtures. Each type serves a specific purpose, such as marking escape routes, providing general illumination, or highlighting critical areas like fire alarm call points. Systems either operate in a “Maintained” or “Non Maintained” mode, where by maintained will keep the light is illuminated all of the time, and when the power is removed, the battery back-up will take over to keep it illuminated. Non Maintained lighting only illuminates when the power is removed. When the power is restored the batteries should then recharge themselves in most cases.
