The Advantium 1 Plus provides an output signal to indicate the alarm condition of the
equipment it is monitoring. This signal is brought out through relay contacts to a 4
position circular connector. The Advantium 1 Plus is factory set so that this output signal
is brought out through Normally Closed (N.C.) contacts. Having these relay set to
Normally Closed allows for configuring multiple Advantium 1 Plus alarms for remote
locations as needed.
The contact polarity can be changed, if needed, to Normally Open. Refer to the section
in this manual “Changing Output Relay Contacts”.
Figure 1 shows a view of the front panel. It is laid out with a single status light on the
right side representing the Inlet alarm output originating from the equipment being
monitored. The System Status indicator light is a bi-colored LEDs. This means that the
same light can be turned ON as either a green indicator or a red indicator. A green LED
indicates a normal condition while a red LED indicates an alarm condition.
In the center of the front panel is an audible transducer. This transducer is used to
provide an audible indication of an alarm condition. In the upper right portion of the
front panel is a button labeled “alarm silence”. This button allows the operator to silence
the audible alarm even though an alarm condition still exists. This audible alarm can be
disabled if desired. Refer to the Section “Muting Audible Alarm” for instruction on how
this is done.
The Advantium 1 Plus input expects a switch connection across two of the pins on its
input connector. The Advantium 1 Plus supplies a +12vdc signal brought out to one of
the pins on the Input connector that serves as the supply voltage for the switch connection
on the equipment being monitored. For normal operation, this switch contact should be
normally closed (N.C.). The Advantium 1 Plus uses the Normally Closed (N.C.) contact
signal from the equipment being monitored to determine the state of the alarm of that
equipment.
If there is no alarm condition, the Advantium 1 Plus will turn ON the green indicator next
to the status being monitored.
When the switch on the equipment being monitored opens, the Advantium 1 Plus
considers this to be an alarm condition. The response from the Advantium 1 Plus is to
change the color of the indicator next to the status from Green to Red. At the same time,
if enabled, the audible buzzer in the Advantium 1 Plus will begin to beep in a pulsing
fashion. In addition, a set of contacts representing this alarm condition will open in the
output section of the Advantium 1 Plus alarm. Both the change in LED color and the
audible alarm will be delayed by 40 minutes if the “Delay Alarm” feature is enabled.
