Clear visual notification during an emergency; approved to EN54-23

VADs provide a clear signal of evacuation for any occupant that may not be alerted by an audible alarm due to working in a noisy environment like a factory, if they are hard of hearing or increasingly in office and educational environments due to wearing headphones.
