NOTES:

1. Horn modulation is self–completing. When going from Alarm to No Alarm, the alarm condition will terminate only when horn is off.

2. Comparators are strobed once per cycle.

3. Low battery comparator information is latched only during LED pulse.

4. Current source required into Pin 1.

5. Alarm Condition can initiate on any clock pulse except 1 and 7.
