The Alpa EcoWent XT Gas Detector can work directly with the Alpa EcoDet XT (connection via X2 terminals).
Then we get a couple of sensors that allows for the simultaneous detection of carbon monoxide (CO) and

The type of gas, the thresholds and the corresponding current value for a specific detector
should be checked in the calibration certificate.
In the course of its work, the detector makes continuous measurements of gas concentrations in the
environment, and carries out regular tests of the sensor. Depending on the outcome of these actions, it
distinguishes between the states described in the following sections.
1.2.1 Operation
It is a condition in which the detector works properly and conducts measurements. The value of the
measured concentration of gas is below the thresholds and no irregularities were detected in the operation.
The detector does not require special attention of the user, except for:
