My opinion is that EN60950 would apply if the equipment is for business use
only. Otherwise, EN60065 would apply for household use and "similar"
purposes. However, you should ask a Notified Body for an official opinion.
You did not ask, but EN50130-4 would apply for immunity effective 1/2001. I
assume that EN55022 would apply for emissions.

Subject: Alarm bell box
I've been asked to give an opinion on an intruder alarm bell box. EN
guidance (CENELEC report R079-001:1998) indicates that either
EN60950 or
EN60065 may be appropriate for safety, and sooner or later I'll have
to
make my own mind up as to which to choose. However, if there's
anyone out
there would not mind telling me which standard they applied in
similar
circumstances, I'd be grateful to hear from them.
The unit is a box intended for exterior wall mounting and it
contains a
piezo sounder, xenon tube and associated circuitry including an
anti-tamper
switch. Incoming supply is actually 12VDC so we won't officially
claim
compliance with the Low Voltage Directive, but it would still be a
good
idea to take a standards-based approach to the design.
Nick.
