The NFPA (National Fire Protection Association), specifically NFPA 72, requires that strobe lights used for fire alarm notification be clear or white, have a minimum flash rate of 1 Hz and a maximum of 2 Hz, and meet specific candela ratings based on room size and mounting height. Strobes must also be synchronized when more than one is visible from the same location to prevent triggering seizures in individuals with photosensitive epilepsy. Additionally, they should be installed so that the light is visible from all required areas.
