Operating modes
Demo mode
Demonstration mode in which the display alternates between displaying the gas concentration and the message Inl .
No alarm is activated and no function may be activated.
This mode is activated using option 0 on the setup wizard or after 60 seconds if none of the other options has
been selected.
If you press any key, the device will return to “Setup wizard” mode.

Compatible stations: AKO-555241 AKO-555242 AKO-558241
AKO-558242 AKO-55624 AKO-55724.
Independent operation
Choose this option if you want the transmitter to function independently.
Both the operation mode and the configuration of the output can be checked using the read only
parameters of
InI and o00 respectively.
5.- Operation
Without alarms
The display shows the current gas concentration in ppm (Parts per million) (If b01 =0) or the
type of gas to be measured ( b01 =1).
Parameter b02 allows you to fix a value below which the display will always show zero.
Concentrations measuring under 75 PPM can be due to measuring or calibration errors. For greater
precision, it is recommendable to carry out a calibration once installation of the transmitter has been
completed.
Sensor error/malfunction
The station emits 3 short beeps every two minutes and the input indicator affected flashes
red.
MUTE function
Mutes the sound and/or deactivates the relays of gas pre-alarms and alarms according to
the configuration of parameter
b03 . This does not affect the operation of the indicators.
To activate this function, press the key at any time when a pre-alarm or alarm is activated. The display shows
the indicator of alarm on mute.
You may also activate this function remotely using digital input 1 (DI1) if required.
This function will automatically cancel each type an alarm changes status (from pre-alarm to alarm, from alarm to
pre-alarm).
