Figure 4-54 Sensor Summary
This display example shows that the sensor on channel 01 has been configured as a Carbon Monoxide Sensor. The
valid entries for Macurco type sensors are Carbon Monoxide (CO), and Nitrogen Dioxide (NO
2
).
Setting the sensor type to 0 (zero) will cause the display to ask if the user wants to DELETE the sensor. If the answer
is yes, the configuration record for this sensor channel will be deleted and the channel will no longer be used to
control the ventilation system. When a sensor’s type is changed, the alarm level, warning level, and range will be set
to the default for the sensor type.
The following three parameters are not accessible until a sensor type of 1, or 2 is selected.
