8.3.7.12
Trigger Type is Time Alert
The DSM570 can be configured with alerts that go active at a predetermined time, such as an alarm
clock. These alerts can also be configured to become active periodically, making them useful for
signaling watch changes (for example, every four hours) or as a personnel alarm (making sure a crew
member is at the helm every 15 minutes).
When a Time Alert with a Repeat Interval of zero is accepted, it will be disabled to prevent further
triggering. When a Time Alert with a Repeat Interval greater than zero is accepted, it will transition to
the Inactive state, waiting for the next time it should trigger.

Alert Time
– The alert will become active at the time specified in this field. If the time specified has
already passed, then the alarm will be set for the next day. Entering a number without the colon will
assume that the hours are zero.
Repeat Interval
– The alert will become active again after the period specified in this field. For
example, if the Alarm Time were set to 8:00 and the Repeat Interval were set to 1:00 (1 hour, zero
minutes), the Alarm would become active again at 9:00, 10:00, and so on.
