The Code 3 temporal pattern (1/2 second on, 1/2
second off, 1/2 second on, 1/2 second off, 1/2 second
on, 1-1/2 second off and repeat) is specified by ANSI
and NFPA 72 for standard emergency evacuation
signaling.
Notice
The Code 3 temporal pattern should be used only
for fire evacuation signaling and not for any other
purpose.
