Then, enter the valid sensor type (displayed in bottom box) of the group to view and press ENTER. Once a valid sensor type has
been entered, the current values for that sensor type or group of sensors in that zone will be displayed as shown below. To
change the values, select the menu item and press ENTER. Then, key in the new value and press ENTER. For NO2 and O2 sensor
press RIGHT key to add a decimal point after a value. E.g. to enter value 3.2, enter 3 press RIGHT key and then enter 2. Panel will
display a message if an invalid value is entered. Values entered cannot be larger than range of the detector, rising value must be
equal or greater than Falling value, and Alarm value must be equal or greater than Warning. Refer to Table 4-2 for default values
for each field or menu item.

The following options are available for GROUP CONFIGURATION:
• RISING – If the gas concentration is greater than or equal to this level, the zone output(s) will be turned on.
•
FALLING – If the gas concentration is less than or equal to this level, the zone output(s) will be turned off.
• WARNING - The gas concentration used to trigger a warning status for the group of sensors within the zone. Setting a
warning level of 0 (zero) will disable warning detection for this sensor.
• ALARM – The gas concentration used to trigger an alarm status for the group of sensors within the zone. Setting an
alarm level of 0 (zero) will disable alarm detection for this sensor.
•
MODE – When multiple sensors are being monitored by a group, the output decision can be based on either voting, or
the average of all sensors in the group. Valid modes are AVERAGE or VOTING (default). The bottom box in the LCD
displays the current Mode used for the group (or sensor type).
o AVERAGE: The gas concentrations from all sensors (of same type) in the group in a zone are averaged and

If the average is greater than or equal to the rising trip point, the zone outputs(s) are activated.

If the average is less than or equal to the falling trip point, the zone output(s) are de-activated.

If the average is between the two trip points, the outputs remain in their previous state.
