CALLBACK ACKNOWLEDGMENT
This is an optional feature that can be enabled using the keypad
(default=disabled). It allows an alarm to be acknowledged simply
by calling the unit and letting the line ring 10 times. When this
feature is enabled it will temporarily make the Rings Until Answer
set to 10 when an unacknowledged alarm exists. If you receive a
call via Voice or Pager and are unable to send touch-tones, you can
call the unit back, let the line ring 10 times, and the unit will answer
and say “...Alarm Acknowledged.”
NOTE: If TAD is also enabled, then you must call the 2800,
let it ring once, hang up, and then call the unit back within 30
seconds. The unit will answer on 1 ring and acknowledge the
alarm.
To Enable the Callback Acknowledgment Feature:
1. Press SENSOR ON/OFF.
2. Press CODE.
The 2800 will say “Callback Acknowledgment Enabled/Disabled” to
indicate that Callback Acknowledgment is enabled. Repeat the key
sequence to disable.
