Kevin,
The LVD covers devices that operate from a source 50V AC or 75 V DC, since
your dummy operates from 30 V it is not covered by the scope of the LVD. In
fact it is illegal to claim compliance to it.

Kevin,
I would CE mark the dummy. My justification is as follows:
it is low voltage and safe, and therefore meets the LVD. I do think that
the LVD applies even if the dummy itself does not have a power source.
Consider that with the wrong power source applied, there COULD be a hazard
(unlikely, but possible). There could be other components inside that
could ignite, etc., once power is applied. By marking it you are telling
everyone in Europe that this dummy has been evaluated to safety and meets
the requirements. As for the EMC Directive, I don't think that this one
applies since the dummy neither receives nor generates signals at any
frequency.

If the product does not include the power source, the LVD
does not apply
since the source voltage is not within the range covered by
the directive.
If the power source is included with the product, the LVD
applies to the
complete product, and I would say that EN 60950 applies.
The EMC directive applies to all electrical equipment. I
would not classify
this product as a security device since it's primary
function is not to
protect persons or property; rather, the primary function is
to blink an
LED. You have no control over what people will infer from
that light.
Therefore, the generic emissions and immunity standards
apply as do the
power line harmonics and flicker standards. I believe that
it can be safely
said that, based upon inspection of the product and its
schematic, there is
no need to perform tests, just declare compliance with the
standards and
place your justifications in the technical file. Perhaps,
the cleanest
method would be to ask a Notified Body for an opinion and
place it in the
technical file.

Subject: Odd CE Marking Question
Hello Group,
I just had a question posed to me that made me think a
little bit. So I will
pose it to all of you. First some preamble. A device is
going to be made
for the European market. It is in fact a "dummy" device in
that it looks
like the real thing but it is not. The only electronics
inside is a bridge
rectifier and a RC circuit to blink a LED. The device can be
powered by
either an AC or DC source up to 30 V. The power source is
not supplied. For
this industry (security) there is a product family standard
for EMC. The
device is not a mock up for store display purposes but is in
fact used in
the industry to give the impression that there are more of
these devices
around than there really are.
So the moment has arrived, do you CE mark the device? If you
say yes, what
directive did you apply? If you say no, what is your
reasoning?
Best Regards,
Kevin Harris
