addition there is an Acknowledge button and a list of the dialout phone numbers.
The Acknowledge button marks the alarm as acknowledged. Acknowledgment has
the following effects:
1. An acknowledged critical alarm will stop dialing out. If a critical alarm is
acknowledged before it has dialed out the first time, it will still dial out once.
2. A normal alarm which is acknowledged before dialing out will not dial out.
3. When all active alarms have been acknowledged, the flashing “Alarm!”
notification that appears in the top blue border of every SC 255 screen will be
turned off.
4. The Ack field in the Active Alarms screen or the Cleared Alarms screen will
be changed to Yes.
5. In the detailed alarm screen, in place of the Acknowledge button, will
appear the level and account number of the person who acknowledged the
alarm.
