CHAPTER 7
OPERATION
After installation and programming have been completed, the Model
1100 is fully operational. This chapter explains the sequence of events
that occur during an alarm dialout to illustrate how the Model 1100
operates. Part One outlines the basic dialout sequence. Part Two pro-
vides a sample programming strategy and details how the 1100 re-
sponds in common monitoring applications.
PART ONE: THE ALARM DIALOUT SEQUENCE
There are 3 stages to a complete alarm event: 1) Alarm Recognition, 2)
Dialout, 3) Acknowledgment. Note that not all alarm conditions that are
sensed by your sensors will go through each stage. For example, some
may not meet the recognition time. Others may be acknowledged locally
before dialout is started. Refer to Part Two of this chapter for detailed
examples.
Alarm Recognition:
1. A sensor wired to one of the alert inputs (1-3, or AUX if used as a 4th
dry contact), or one of the built-in sensors (high/low temperature, AC
power) detects an alarm condition.
2. The condition must last long enough to meet the recognition time.
NOTE: AC power is programmable from 1 to 199 seconds. All
other inputs are preprogrammed to recognize an alarm at 200
milliseconds.)
3. If the condition lasts the recognition time, the 1100 considers it a valid
alarm and begins the dialout alarm sequence. Go to Dialout.
4. If the condition does not last the recognition time, the 1100 will not
consider it a valid alarm. The 1100 will not dialout.
Dialout:
1. The 1100 waits 30 seconds (30-second call delay time on first call only.
Waits 60 seconds between subsequent calls) after the alarm is recog-
nized before dialing Phone #1. During this time (if local voice mute is
OFF), the 1100 will recite an alarm message locally to indicate which
input is in alarm. If on-site personnel acknowledge the alarm within the
first 30 seconds, the unit will not dialout.
2. The 1100 dials Phone #1. Immediately, it will begin reciting its dialout
alarm message. It repeats the message four times. After the fourth
recitation, the unit requests acknowledgment.
NOTE:
The 1100 DOES NOT wait until the phone is answered to
begin repeating its alarm message. It is reciting its message
when the line is busy, while the phone is still ringing, or when the
