SETTING OF ALARM RESUME TIME
The buzzer is cancelled by pressing buzzer stop key (BUZZER) on the control panel during alarm condition.
However, if the alarm condition is continued after the “alarm resume time” has passed, the buzzer sounds
again.
It is possible to change the alarm resume time by the procedure shown in the Table 8.
The example in the table is based on the assumption that the desired duration is 20 minutes.
Note: Factory setting; 30 minutes.
