If they wonted to say part type or range of part types they would certainly

Piotr,
Have you also looked at EN
the carrier and asks if any transponder is
in field so it modulates the carrier. If not it switches the carrier off, if
yes the carrier exists a little longer to read the whole transponder answer.
The tests in my opinion should be possible with device working as it is
intended to do.

Piotr,
Isn’t it wonderful when lawyers write documents which technical
engineers are supposed to use to meet the legal requirements.
Synonyms from my
14/35/EU should not apply to radio equipment.
This means that the RED applies the safety provisions of the LVD,
without the administrative texts that are not about safety, since if
they were included they would partly duplicate (even maybe contradict)
the corresponding provisions in the RED.
there is common understanding that if RED then no LVD but I don't
like to relay on such sources if I can't understand why it is so.
Do really for native English speakers it is clear that "devices shall

Hi Rich,
Thanks for confirming that isolation in doorlock can be only functional.
This eliminates me one conception that 12V can be ELV, but second
isolation is in doorlock.
So now, as I'm sure that 12V have to be SELV/PELV I have to ask them if
it is.
I know that for other supplies they
ower value resistances than if PELV is connected by this to
other circuit is it still other circuit or they are boith the one circuit.
I think It would help everyone if examples of situations in mind would
be just written everywhere where PELV and SELV are defined.

In 5.2.2 there is the sentence: "However, for a SECONDARY CIRCUIT that
