DESCRIPTION
Safe-NET Display Module
The Safe-NET Display Module, shown in
Figure 1 and Figure 2, is a temperature-
monitoring device. The display module reads
and displays temperature sensed by the product
simulator temperature sensor mounted in the
refrigerated space. The display module notifies
the user of alarms based on preset alarm
conditions.
Alarm Module
The alarm module, shown in Figure 3, is an
additional feature to Safe-NET. The alarm
module supplies power to the display module via
an 8-wire cable. The alarm module provides
battery back up power to the display module
during loss of A.C. power. The display module
communicates with the alarm module via a
2-wire cable. Additionally, the alarm module is
equipped with a beeper to provide audible
notification of alarms.
