A2 overrides A1 on the LED. However, the
A1 and A2 relays operate independently.
I.e. if A1 is acknowledgeable and A2 is
not, and the gas concentration is such that

it triggers A1 and A2: acknowledging will
cause the A1 relay to release. However,
the red LED will still double blink as long
as the A2 condition continues to exist.

Sensor principle

Dräger electrochemical sensors are measuring the partial
pressure of gases under atmospheric conditions. The
monitored ambient air diffuses through a membrane into the
liquid electrolyte in the sensor. The electrolyte contains a
measuring electrode, a counter-electrode and a reference
electrode. An electronic potentiostat circuit ensures a constant
electrical voltage between measuring electrode and reference
electrode. Voltage, electrolyte and electrode material are
selected to suit the gas being monitored so that it is
transformed electrochemically on the measuring electrode and
a current flows through the sensor. This current is proportional
to the gas concentration.
At the same time, Oxygen from the ambient air reacts at the
counter-electrode electrochemically.
The current flowing through the sensor is amplified
electrochemically, digitized
parameters (e.g. the ambient temperature).
