The other timing characteristics are some multiple of the oscillator timing shown in the table. The timing shown should accommodate the
NFPA72, ANSI S3.41, and ISO8201 audible emergency evacuation signals.
2. Typicals are not guaranteed.
3. Time is typical-depends on what point in cycle the signal is applied.
