The scan performs the action for the first alarm and
adds the other alarm numbers to the video in
numerical order.
•
When the first alarm is acknowledged, the scan
performs the action for the next alarm with the
lowest number. For example, alarm contacts 2,
4, and 3 close in the order stated. The monitor
display appears as AL-234. The scan performs
the action programmed for alarm 2.

The AL continues to flash until all alarms are
acknowledged and then is removed from the
display.

The alarm numbers flash until the alarm contacts
return to normal (open). When alarm 2 is
acknowledged, the number 2 is removed from the
alarm display and the scan performs the
programmed action for alarm 3. When alarm 3 is
acknowledged, the number 3 is removed from the
alarm display and the scan performs the
programmed action for alarm 4.
NOTE:
An alarm can be acknowledged before the contact returns to normal;
however the KD6i will not respond to the alarm again until the contact has
reopened and closed again.
