•To enter “555,” press the number (5) key on the Touch-Tone
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 and enter the “555”
acknowledgment code. If you are calling from a pulse or
rotary telephone, refer to Callback Acknowledgment, Section
6.1.3, below.
6.1.3 Callback Acknowledgment
Callback Acknowledgement is a feature that allows you to
acknowledge an alarm without entering Touch-Tones. This
feature is disabled by default and must be enabled by entering the
key sequence below. When Callback Acknowledgment is enabled,
simply call the unit back and allow the line to ring 10 times. The
unit will then answer the call, give a Status Report, then say
“Warning message received by telephone number ...” and recite
the telephone number last dialed. This indicates that the alarm has
been acknowledged.
To enable or disable Callback Acknowledgement:
1. Press SENSOR ON/OFF.
2. Press PHONE NUMBER.
The model 1108 will say “On”to indicate that Callback
Acknowledgment is Enabled, or“Off” to indicate that Callback
Acknowledgement is Disabled. This method of remote alarm
acknowledgment works with any telephone: pulse, rotary, or
Touch-Tone.
