As there is no process for certifying alternative methods, except in transportation facilities under DOT enforcement, a mathematical guide program has been developed by which engineers can demonstrate fire alarm visual notification coverage equivalent facilitation in the event of irregular (non square) rooms and other challenging projects not listed on the prescriptive tables from NFPA 72, National Fire Alarm and Signaling Code. The technical provisions from UL Standard for Safety 1971, Signaling Devices for the Hearing Impaired, are used as an approved performance based criteria in lieu of the requirements found in chapter 18 on notification appliances.
