Alarm Test
Use the alarm test to simulate a gas concentration for any analyzer.
Note:
The alarm test simulates an actual alarm condition and the Vertex M System activates all alarm relays. Notify ap-
propriate personnel that you plan to conduct an alarm test.
threshold concentration is set via the configuration utility as described in
Point. The Create Alarm Now button becomes visible only after the prerequisite selections of analyzer,
point and alarm level have been made. Pressing the Create Alarm Now button creates the simulated
alarm. The above screen contains examples of how alarm simulation works. A concentration of 50 ppb
is being reported over the control network and OPC on point 2-2-3. The value 50 ppb is the alarm 2
threshold for this point from the configuration profile. However no concentration is being reported for
2-2-5 because the scope was set to Event And Relays Only when this event was generated. Pressing
the Create Alarm Now button above will create a level 2 alarm with concentrations on point 2-2-4.
5. To continue testing, repeat steps 2 and 3.
If you choose to simulate a Level 2 alarm, you will trigger both Level 1 and 2 relays.

to clear events.
To conduct an alarm test:
1. Choose Main Screen, Menu, Service
and then Alarm Test.
2. Choose the analyzer and point for the
alarm test.
3. Choose an alarm level and a simulation
scope. Either scope will cause an alarm
to be reported on the control network, on
the relays (if equipped) and on the relevant
OPC tag. Furthermore, either scope will
cause creation of a simulated alarm event in
the event list.
4. However, if "Full Simulation With
Concentration" is selected then a gas
concentration will also be reported on the
control network, on the associated OPC
tag, on the point detail screen, and in the
event. This concentration will correspond to
the alarm 1 or 2 threshold concentration,
depending on which is simulated. The alarm
