SCADA 3000 User’s Manual
Tip: When SCADA 3000 is programmed to make calls to alphanumeric 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 - modem Dialout
SCADA 3000 will dial to a PC running the SCADA 3000 software in Receive Alarm mode and
deliver an alarm message that will be logged by the software.
SCADA 3000 will transmit the alarm information to the PC, hang up and wait for a callback
acknowledgment. This waiting period is called the “intercall delay time.” During this time you
may call the unit back from a Touch-Tone phone and enter the code to acknowledge the alarm.
Note: An alarm cannot be acknowledged using a pulse (rotary) telephone.
Alarm Acknowledgment - maximum Calling Rounds
The SCADA 3000 will dial all of the destinations repeatedly until the alarm is acknowledged.
If the unit reaches the maximum number of calling rounds without being acknowledged, it will
stop the dialout and acknowledge itself. When this occurs, a message is recorded in the Event
Log.
Alarm Dialing Priority
This feature will make alarm dailout the priority if an online session exists. As a result, when
the option is enabled, the unit will drop the online session and begin dialing out when an alarm
occurs. This feature is useful if you have a computer online with the unit 24 hours a day, 7 days
a week, but if an alarm occurs, you want the alarm phone calls to take priority. To enable this
feature click on the System button from the toolbar or select Programming, then System from
the main menu. Next, click the Advanced button within the Dialout Settings group. The follow-
ing form will appear. Click in the Alarm Dialing Priority box to enable this option.
Viewing Current Alarms
You can view all current alarms from one or more units that are online by clicking the Alarms
button from the Sensaphone Control Center toolbar, or by clicking History, then View Alarms
from the main menu. You can also acknowledge alarms from this screen. A sample is shown
below.

Computer Alarm Reception
Alarms from your SCADA 3000 unit(s) can be received and logged on a computer when the
destination type in your SCADA unit is set to modem. The computer that will be receiving the
alarm calls must have a modem, the computer must be on continuously, and it must be run-
ning the SCADA 3000 software. To enable your computer to receive alarms click on Comm
then Setup from the Control Center form. Select the Comm Port tab which corresponds to your
modem and click the box that says Answer Incoming Calls. See sample below. This will set your
modem to answer when the phone line rings.
