The book provides a wide variety of circuits that can be built for alarm systems. The components are now outdated and harder to get since Radio Shack has gone out of business. This was likely a useful book in its day.

An ok book, I like that is has the explanations for the circuits with give you enough information to adapt them.

An error or two in the circuit diagrams, some projects have little practical use. Still worth a read.
