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.
