AUTO DIAL
The Npower UPS can automatically dial (through the optional modem) each of two pre-programmed
telephone numbers (up to 12 digits) when specified alarm conditions occur within the UPS system.
The Npower attempts to dial the first number three times at 45 second intervals. If there is no
answer, the system rolls over to the second number and repeats the process. If there is no answer on
the second number, the system goes back to the first number, repeating the process. The system con-
tinues this sequence until connected or disabled.
Upon connection, the system transmits data, in ASCII format, that includes the system identification
code, the present alarm message(s) and the time that the alarm(s) occurred. Refer to 3.5 - Communi-
cation Interfaces.
Refer to the Special Functions column in Table 7 - Alarms, functions, and corrective actions to
see which alarm messages will initiate an auto-dial call.
If the auto-dial numbers were specified at time of order, the numbers are pre-programmed into the
system. However, if the numbers need to be changed, follow these steps:
1. From the System Configuration screen, press the Up or Down button to move the highlighted
cursor to Auto Dial and press SELECT.
2. The Auto Dial screen will appear. Highlight and select the first Auto Dial Number.
3. Press SELECT to move the arrow to the right.
4. To change a digit, press Up to increase the number or press the Down button to decrease it. Press
Select to set the value and move to the next digit.
5. After changes have been made, press SELECT again to return to the System Configuration
screen.
6. If required, go to the Second Number screen and enter the correct number.
7. If required, go to the Modem Baud Rate screen and choose from the available baud rates.
Customer Alarm Interface
The Npower UPS offers a Programmable Relay Board option allowing the Operator to program cer-
tain alarms or events to activate single or multiple output relays. (See Section 6 in the Options man-
ual.) In addition to the user-defined programming capability of the system, the Npower offers two pre-
defined relay assignments: AS400, where only the first 3 relay assignments are pre configured (with
the other 5 assignments available for user definition, and Standard Set, where the first 7 relays are
assigned with the remaining one left unprogrammed. (The 8th assignment is not available for user
definition.)
This means that the Operator can choose among the following three configurations for each of the two
Programmable Relay Boards.
• AS400
• Standard Set
• User Defined
The default configuration is User Defined.
To access the proper screen for configuring the Programmable Relay Boards:
1. Navigate from the MAIN MENU to the CONFIGURATION screen.
2. From the CONFIGURATION screen, use the arrow keys to highlight CUSTOMER ALARM
INTERFACE and press SELECT.
This action will bring up the following screen.
