Chapter 7: Operation
After installation and programming is completed, the Model 1104
is fully operational. This chapter explains the sequence of events
that occur during an alarm dialout to illustrate how the Model
1104 operates.
7.1 Alarm Detection, Dial-out and Acknowledgment
Generally, an alarm event is structured in the following manner:
I. The Model 1104 detects an alert condition due to 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 table on the following pages explains the alarm detection,
dial-out and acknowledgment features and lists important variable
factors affecting their operation.
