Buffer Limitation
The Zone Coordinator holds the last 50 alarms in memory, whereas the System Man- ager keeps the last 150 alarms. When the buffer limit is reached, the newest alarm replaces the oldest alarm. All alarms kept at the Coordinator are also forwarded to the System Manager. If the Coordinator cannot forward the alarms to the System Manager, the last 50 alarms are kept at the Coordinator, then sent within 30 seconds after com- munication between the two devices has been restored.
Alarm Detection
When a new alarm occurs, the Alarm icon on the display turns red and begins to blink. Also, the Alarm LED on the upper right corner of the display turns from green to red. The Alarm icon returns to its normal state and the Alarm LED returns to green after you select the Alarm icon at the System Manager or Coordinator.
You can view alarms by pressing the Alarm icon from the Home screen. The most recent alarms are listed first. After you view the alarms in the system, you can delete them, either one at a time or all alarms at once.

Pagers
The System Manager or Coordinator can send alarms to paging devices. When a criti- cal alarm occurs, the internal modem in the device uses the pager configuration param- eters to establish communication with the paging system. The device passes the alarm to the paging system, then routes it to the pager. The time required for the alarm text to reach the pager depends on several factors, including the speed and reliability of the paging service.
