2. TECHNICAL AND CONSTRUCTIONAL INFORMATION
• SPR and SPR RADIO sensors signal the rain event to an apparatus able to
interpret and command the connected devices. The sensor is insensitive to the
formation of dew or moisture after rainfall dries very quickly and being heated -
below +5 °C - does not allow the formation of ice.
• The sensor is fed with a tension between 12V and 24V
• Electrical connection must comply with the rules in force on electrical systems.
• All connected devices must be manufactured according to the regulations in
force and comply with regulations issued by the European Community.

4. ID PLATE AND MARKING DATA
SPR and SPR RADIO rain sensors have CE marking and comply with the
Standards listed in the Declaration of Conformity.
The plate data is displayed on an adhesive label placed on the outside of the
casing, which must remain intact and visible.
The main information it displays includes: manufacturer's address, product name -
model number, technical characteristics, production date and serial number.
In the event of a complaint, please indicate the serial number (SN) displayed on the
label.
An explanation of the symbols used on the label to abbreviate the technical
characteristics is given in the table in the chapter on "TECHNICAL DATA".
5. TECHNICAL INFORMATION
SPR or SPR RADIO rain sensor, to completely fulfil its task, has to be placed out in
the open fully exposed to any precipitation, possibly over the roof or in a similar
position, or where can be affected by rainfall.
