Both interfaces cannot be used simultaneously because the RS232 port will be disconnected
automatically after plugging the USB cable into the port.
Alert switch
Both, Radon Scout and Radon Scout PLUS are equipped with a switch output which can be
used for ventilation control or alert indication. The potential-free contacts of the switch will be
connected at the end of the sampling interval if the measured Radon concentration exceeds
the threshold. The output will be deactivated one minute before the subsequent interval
ends. Therefore, the sampling interval must be set at least to two minutes. The alert
threshold is fixed at 300Bq/m³ for the Radon Scout while it is user adjustable in the Radon
Scout PLUS. The connector is located on the rear panel of the instrument. In case of pending
alert, the red light at the front panel will blink instead of the green one.
As an accessory, we offer a wireless power switch which can be used for direct ventilation
control. The switch includes a transmitter unit to be connected to the alert switch output of
the instrument, and a plug adaptor (receiver) which can be placed between the wall outlet
and the power cable of the ventilation unit. Optionally, a flush-mounting power switch is also
available. The plug adaptor offers an additional timer function to define the duration of the
ventilation period independently on the sampling interval of the instrument (for example 15
minutes on while the sampling interval is 60 minutes). The wireless switch is coded - that
means, several transmission lines can be established within one building. The assignment
between transmitter and receiver is easily done by a push button.
The sampling interval should be set to 60 or 120 minutes if the threshold level is lower than
300Bq/m³.
