Calling A Pager - Liebert 300 series Installation, Operaton & Maintenance Manual

If the Modem Mode is set to either OUT or
BOTH, the UPS will dial out on any of the
following events:
ID Code Delay
0 0
1 0 Automatic battery test
failed
3 60 Sec. Alarm event, load is on
3
60 Sec. Utility outage, load on
is in danger of shutdown
5 60 Sec. Load has been transferred
to static switch. Overload
or other alarm condition
present.
6 0 Load has been shut down
Each event has a delay and ID code. The ID
code can be transmitted to a pocket pager to
identify the event. The delay is the amount of
time that the condition must be continuously
present before a dial-out will occur. This delay
exists to prevent the UPS horn dialing out
common. For example, in areas where the utility
power is unreliable, power failures may be a
daily event. The UPS will not dial out unless a
power failure lasts at least 60 seconds.

Calling a Pager

When the UPS calls a pager, it uses the touch-
tone generator in the modem to create the tones
required by pager services. There are two
numbers involved when calling a pager
The telephone number of the pager service
l
access line (the service number)
. The number to be transmitted and displayed
in the pager window (the display number).

Event
Dial-out test
Consider what happens when you place a call to
a pager:
1. You dial the pager service number
2. The pager service equipment picks up the
phone after a few seconds-usually it beeps
a few times. This is your cue to enter the
display number
3. When you're done entering the display
number, you hit the pound (#) key to let the
pager service know you're done
4. Usually the pager service plays a recorded
acknowledgment message.
Be aware that although the UPS has the ability
service equipment can hear, the UPS
hear any sound generated by the pager service.
Thus the UPS must "dial blind-it dials the
display number and hopes it was received
properly. Since the UPS cannot hear either the
cue or the acknowledgment, there is a chance
that if the dial-out fails the UPS will have no
way to know that it has failed. If this is a
concern you may want to have the UPS call two
different pagers, or a pager and a modem.
There are 2 fields on each of the UPS phone
number screens which you should understand
when setting up a pager (read '%diting the
Phone Numbers" on page 5-13 for more about
how to edit the fields). When the UPS is &St
installed, the default phone number screens look
like this:
Phone Number 1
Pager Disabled
Pager Delay: 13
