Model 1108 User’s Manual
70
Example: You receive a call from the Model 1108, reporting
that an alarm exists. The message concludes: “Indicate you
have received warning message.” Now, or at any time during
this call, you may acknowledge the alarm with the code “555”
if you are using a Touch-Tone
TM
telephone.
• To enter “555,” press the number (5) key on the Touch-
Tone
TM
phone keypad three times. The Model 1108 will
respond: * “Warning message received by telephone
number (last number dialed).” The Model 1108 will
hang up and the dial-out sequence, including any further
response to the alarm, will be cancelled.
• If you enter the wrong code or do not enter it within
10 seconds following the conclusion of the message, the
Model 1108 will respond: “Dial telephone number (the
programmed unit phone number) within (Intercall
Time).” Then, the Model 1108 will hang up. The alarm
is still not acknowledged until you call back. You have a
period equal to the programmed Intercall Time to call
the unit back in order to acknowledge the alarm. Refer
to Callback Acknowledgment, Section 6.1.3, below.
6.1.3 Callback Acknowledgment
This method of remote alarm acknowledgment works with any
telephone: pulse, rotary, or Touch-Tone
TM
.
Example: The Model 1108 calls you with an alarm message.
You answer the call with a rotary or pulse telephone, and do the
following:
• You listen to the message and hang up.
• Then you call the Model 1108 back on any
telephone.
You must wait for 10 rings—this signals the Model
1108 to answer your telephone call. (Make sure to call
back within the programmed setting for Intercall
Time—refer to Chapter 4, Section 4.11.)
When the Model 1108 answers your return call, it gives a
Status Report (refer to Section 6.2). Then it says:“Warning
message received by ...” and recites the telephone number last
dialed. This indicates that the alarm has been acknowledged.
