PROTOCOL
The pager module uses the Telocator Alphanumeric Protocol (TAP), which is the protocol used for
SkyTel pagers. A copy of this protocol is included with the pager option. Pager support requires the
same hardware that modem support requires. The internal modem is quite adequate.
Since the pager option uses the same modem that the modem option uses, careful thought has gone
into the sharing of one modem. For example, incoming connections take precedence over dial out
alarms or pager alarms. When a dial out alarm is articulated, each number is tried at least 3 times
before giving up. After giving up, the pager module gains access to the modem, and will begin trying
to send the alarm to a pager. If modem dial out is disabled but pager dial out is enabled, the pager
alarm will skip the modem dial out module and proceed immediately to the pager module dial out.
When an alarm message is sent to the pager, it includes a system header and a data portion that
looks like the following:
System ID# 00000000 System Tag # 00000000
1 BATTERY FUSE FAIL 5/11/01 3:22 PM
A list of alarms, masks, and corrective action is shown in Table 7.
3.5.3 Remote Alarm Status Panel
The NPower UPS may be ordered with an Optional Remote Alarm Status Panel. This remotely-
mounted panel (within 500 feet), provides an LED indication of the following Alarm conditions:
• Load On UPS
• Load On Bypass
• Battery Discharge
• Low Battery Warning
• Overload
• Ambient Overtemp
• System Summary Alarm
• New Alarm
The Remote Alarm Status Panel housing is a NEMA Type I enclosure, available for remote mounting
on walls or columns. The Remote Alarm Status Panel displays the 8 alarms specified above. Signals
for the alarms are carried over a 4-wire connection (customer supplied) which connects the Npower
CANBUS data link and Optional Power Supply to the Remote Alarm Status Panel.
3.5.4 SiteScan
The SiteScan port sends UPS system information to a Liebert SiteScan Central Monitoring System.
UPS operation, environmental control systems, and facility security can all be monitored from a sin-
gle location.
