7.8.3 Pager Setup - Pager Number and PIN
The Liebert AC8 may be configured to dial numeric or alphanumeric pagers when an alarm is detected.
You may enter up to four pager numbers—all configured pagers will be dialed each time an alarm occurs.
For each configured pager, you must enter the pager number to be dialed and the pager’s Personal
Identification Number (PIN).
See Liebert AC8 Specifications on page107 for supported pager settings.
The Liebert AC8 can send numeric or alphanumeric messages to supported pagers, as shown in the
following example:
When an alarm is detected, the first pager number is dialed—up to three times, if needed. After a
successful page or three dialing attempts, the next pager number is dialed, again with three attempts as
needed, and so on for all configured pagers.
