the code to acknowledge the alarm. NOTE: An alarm cannot be
acknowledged using a pulse (rotary) telephone unless the Callback
Acknowledgment feature is enabled.
TIP: When the 1800 is programmed to make calls
to alphanumeric pagers, make sure the intercall
delay time is long enough to give the person carry-
ing the pager some time to get to a phone to call the
unit back.
Alarm Acknowledgment—Automatic (Max Calls)
The 1800 has the ability to acknowledge itself by using the Max
Calls function. The unit keeps a count of the number of phone calls
it makes for a particular alarm. Once the number of calls made
reaches Max Calls, the 1800 will acknowledge the alarm and stop
the dialout process.
