What can you tell me about visual alarms for the deaf being triggers for seizures? I'm currently seeing a lot of anecdotal articles saying it is a problem but I'm not finding alarm systems that have more than 1hz per second flash rate which according to the epilepsy foundation is below the problematic rate. At the same time, I also need to know more about how brightness might affect issues. I'm trying to see what types of equipment would work in an office that will serve both. (Technically all places should have a design that works for both).
