Preparing a VFC400-USB for first use

VFC400-USB User Guide

18

Once an alarm has triggered, the alarm indicator ( ) remains shown until the unit is
reconfigured. The day alarm marker

remains shown until midnight, then it turns off

and the marker for the previous day is shown (

) to indicate the alarm was registered

against what is now the previous day. When midnight passes next, this marker will
move to and so on.

Alarm Re-triggering

A note on alarm re-triggering:

As soon as an alarm is triggered, the

corresponding delay time (but not any others) resets to zero and alarm
processing starts again. The alarm processing for all other alarm delays is not
affected. Therefore, accumulative or consecutive alarms will re-trigger, if the
alarm conditions are met again, and the Alarm Indicator ( ) and the Day Alarm
Marker (

) will be shown, even if any previous alarm was cleared.

Clearing an

Alarm does not reset any of the delay values.
