CHAPTER 6: OPERATION
After installation and programming is completed, the Express II is fully operational. This
chapter explains the sequence of events that occur during an alarm dialout to illustrate how the
Express II operates.
Alarm Detection, Dial-out and Acknowledgment
Generally, an alarm event is structured in the following manner:
I. Express II detects a change at the sensor.
II. A valid alarm is recognized.
III.
Dial-out begins.
IV. The alarm is acknowledged.
Often, an alarm does not proceed through all stages: either an alert condition does not persist
long enough to be considered valid, or a valid alarm is cancelled.
The following table explains the alarm detection, dial-out and acknowledgment features and
lists important variable factors affecting their operation.
