Overview
One of the most important requirements of any network
environment is its ability to notify personnel of system fail-
ures or possible problems. REFLECS controls are designed
with sophisticated logging, graphing, notification, and
alarming features that put system data at the fingertips of
the service technician or store manager. However, no net-
work is complete without the basic ability to provide an-
nunciated alarms in the event of serious system problems.
CPC uses the 485 Alarm Panel (Figure 1) to accom-
plish this task. The 485 Alarm Panel is linked to all RE-
FLECS Controllers through the RS485 COM B Host
Network. Although the alarm panel has many features that
make it a powerful notification tool, the primary and most
important function of the alarm panel is to receive signals
from the REFLECS and deliver an alarm annunciation.
The REFLECS constantly compares real time system
conditions against user-defined alarm set points. When a
system reading falling outside of these set points is detected
by the REFLECS, a signal is sent to the alarm panel, which
in turn emits an alarm signal and displays the alarm infor-
mation on the notification screen.
