Notes
6. Oscillator period T (= Tr + Tf) is determined by the external components R1, R2, and C3 where TR = (0.6931) R2 C3 and TF = (0.6931) R1 *
C3. The other timing characteristics are some multiple of the oscillator timing as shown in the table. The timing shown should accommodate
the NFPA 72, ANSI S3.41, and ISO 8201 audible emergency evacuation signals.
7. Typicals are not guaranteed.
8. Time is typical - depends on what point in cycle signal is applied.
