detectors that meet the characteristics of the other two criteria set in
“Profile”
and
“Gas
Type”.
Each gas detector code is indicated on the device identification label.
The
“Channel Description”
is not mandatory for the reliable function of the gas
detection system. It is an aid for the user to indicate useful additional information in the
case of alarms.
In the case of alarms all information related to the detector(s) in alarm condition will be
indicated at the display on request.
The

“Alarm Settings”
the threshold values for all three alarm levels can be
modified within a specified range indicated by the red bar and a sliding control.
