Timed mode turns the zone’s outputs on at the START TIME if the current day is a weekday (or a weekend) and turns them off at the
next occurrence of STOP TIME. The other three modes turn the outputs on if the gas concentration indicated by that type of sensor is
at or above the Rising Trip Point and turns the outputs off if the concentration is less than or equal to the Falling Trip Point.

Figure 3-47 Sensor Selection
Sensors are included or removed from the group by entering the two-digit channel number. After a sensor is added or removed, the list
will be re-sorted so it does not matter in which order the sensors are added or removed. The default is to include all sensors of the
specified type.
When the first digit of a sensor number is entered (a leading zero must be entered if the number is less than ten), the display will
prompt to Add or Remove a sensor from the group.
