Explanation
Fire alarm visible appliance source intensity is measured in candela, which is the unit of luminous intensity in a given direction. Candela is defined as the amount of light emitted by a single candle in a specific direction.
The intensity of a strobe light depends on the candela rating, the flash rate, and the flash duration. The higher the candela rating, the brighter the light. The National Fire Protection Association (NFPA) and the Americans with Disabilities Act (ADA) have established minimum and maximum candela ratings for fire alarm visible appliances in different locations and applications.References:Strobe Light Requirements: Proper location of visible notification ...;Handbook of Visual Notification Appliances for Fire Alarm Applications;Audible Visible Appliance Reference Guide - Fire - studylib.net
