CHAPTER 7: OPERATION
79
has not been acknowledged. The 1800 will hang up and wait for you to call
back and enter the acknowledgment code. This waiting period is called the
INTERCALL TIME. During this time you may call the unit back from a
Touch-Tone phone and the unit will give a voice report. Once you receive
the complete report, enter the code to acknowledge the alarm.
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 pagers,
make sure the intercall delay time is long enough to give the person
carrying 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 func-
tion. 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. The default
setting for Max Calls is 100.
CALL-IN STATUS
You can also call into the 1800 using a Touch-Tone telephone to obtain
a status report. After answering, the 1800 will recite a status report.
Immediately following the status report, the 1800 allows you to use Touch-
Tone commands to enable/disable zones, change limits, control the output,
etc. See the next section, Remote Commands via Touch-Tone Phone.
Below is an example of a voice status report:
“Hello, this is 555-2278, ‘Acme Medical Laboratory’

“Zone five, ‘Ventilation fan speed in RPM,’ 250, OK
“Zone six, ‘Phase B power,’ OK
“Zone seven, ‘Compressed air pressure in PSI’ 100, OK
“Zone eight, ‘Security alarm,’ OK
