Viewing Alarms

You can view alarms in two ways: Current Alarms or Alarm Log history.

You can view the alarms for either the active card or the standby card.

To View Current Alarms

The Current Alarms screen displays the date and time the alarm started, de- tails about the alarm, the time remaining on the Alarm Cutoff (ACO) timer (if it has been engaged), and where you can engage and disengage the ACO. Engaging the ACO closes the external alarm contacts, turning them off, while disengaging the ACO turns external alarms back on.
