10. Functional description
When the A & B inputs set or reset according to the priority required and the STROBE is applied as
shown in the Timing diagram, the alarm is triggered only once. The alarm completes one cycle as per the
priority and stops. To avoid spurious triggers and retriggers, please follow the Timing diagram critically.
