SETTING OF ALARM RESUME TIME
The alarm buzzer and remote alarm are silenced by pressing BUZZER key on the control panel during alarm condition. The buzzer and remote alarm will be activated again after certain suspension if the alarm condition is continued. The suspension time can be set by following the procedure shown in the Table 6 below.
The example in the table is based on the assumption that the desired duration is 20 minutes. Note: The duration is set in 30 minutes at the factory.
