3.3.3 Configure Sensors Submenu

There is a list of parameters for each sensor in the system, either currently wired or configured but presently disconnected. The left and right cursor keys can be used to move from one sensor to another; doing so always goes to the first display (summary). The up and down keys will scroll through the parameters for the particular sensor.

Figure 3-24 Sensor Summary

This display example shows that the sensor on channel 01 has been configured as a Carbon Monoxide sensor with an Alarm level of 200 ppm and a Warning level of 50 ppm.

Notice that the sensor number, 01 in this example, is underlined. This indicates that the digit keys can be used to jump to a particular channel, even if there is no sensor connected to the channel. When the first digit is entered, the display will prompt for the sensor to show.

Figure 3-25 Sensor Type

This display example shows that the sensor on channel 01 has been configured as a Carbon Monoxide sensor.

The valid entries for the sensor type are:

 

–

1

Carbon Monoxide

(CO)

–

2

Nitrogen Dioxide

(NO2)

–

3

Combustible

(EX)

–

0

None

(---)

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. If a sensor indicates trouble (or there are wiring problems on a channel), this will stop any annoying trouble signals for this channel.

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, 2 or 3 is selected.
