EXAMPLE 3:
Alarm Recognition:
A magnetic reed switch monitors entry and exit on the back door of a warehouse. After
hours, one of your employees returns to the warehouse to complete some unfinished work.
He accidentally trips the alarm on the back door. To prevent an unnecessary dialout, he
locally acknowledges the alarm by pressing a key on the keypad.
EXAMPLE 4:
Alarm Recognition:
You are monitoring the temperature in your greenhouse using a Temp°Alert wired to the
AUX TEMP input. (Note: The Temp°Alert is a dry contact sensor. It is not the same as a
remote temperature sensor and does not provide an exact temperature reading.) The
temperature rises above the set high limit on the sensor and triggers an alarm. The
condition lasts longer than 200 milliseconds, so the 4100 recognizes it as a valid alarm. It
recites the alert message locally for 30 seconds. The alarm is not acknowledged, so it
continues with the dialout sequence.
Dialout:
1. The unit dials Phone #1. It recites its message and requests acknowledgment. It does
not receive the touch-tone code within five seconds. The unit requests callback
acknowledgment and hangs up.
2. The unit waits 60 seconds but does not receive callback acknowledgment.
3. The unit dials Phone #2 and repeats the alert message-acknowledgment request. It
receives no touch-tone acknowledgment or callback acknowledgment.
4. The unit dials Phone #3 and repeats the alert message-acknowledgment request.
Again, it receives no acknowledgment.
5. The unit continues and dials Phone #4. This call is to a beeper. The 4100 sends the
touch-tone code 1234 to the beeper. You read the code 1234 on your beeper and know
to call the 4100 back. Although you cannot hear the recitation, the 4100 repeats its
alarm message and requests acknowledgment.
Acknowledgment:
1. Since you received the message on a beeper, you have 60 seconds to call the unit back
to acknowledge the alarm and stop the unit from dialing the next number.
2. You manage to get to a phone and call the unit back but not within 60 seconds. The
unit waits 10 rings and then answers (TAD disabled).
3. The 4100 provides a status report and then says:
“Warning message received by telephone number 555-1111.
Have a good day.”
4. Because you did not call within 60 seconds, the unit dialed the next number,
Phone #1. When it receives the callback, it always indicates that the message was
received by the last dialed number.
