[110] candela measured in accordance with UL 1971, but in no case less than
the effective intensity [required by NFPA 72 for the appliance spacing and
location] [shown]. Lamps shall be protected by a thermoplastic lens and
labelled "FIRE" in letters at least 12 mm 1/2 inch high. Provide visible
appliances within 300 mm 12 inches of each audible appliance [and as
indicated]. Visible appliances may be part of an audio-visual assembly.
[Where more than two appliances are located in the same room or corridor,
provide synchronized operation.]
