Regarding Roger Secura’s “Build a
Wireless Silent Alarm Warning
System” article in the December 2013
issue: This article was superb. The
graphics were great, it was very
complete with completely descriptive
text, BOM, sources, a plain English
picture of the installation, a plain
English view of the components, and
very clear circuit diagrams. This article
should be held up as a standard to
which all articles should be written.
Regarding Roger Secura’s
December issue project and the
TWS434A and RWS434 parts.
I went to www.rentron.com to
obtain parts as directed by the
article. The website is no longer in
service and the phone number is
disconnected. I tried several parts
companies for the two parts, but no
luck. Anyone locate a source?
I found some suppliers that carry
the TWS434A and RWS434 parts; see
the list below.

RWS434 Receiver = $7
