Inhaltsangabe
The old adage of the late security consultant Don Darling - 'One Wire not enough, two wires very fine, three wires too confusing" - has gone the way of the covered wagon. The alarm industry has entered the computer age, and now a hundred wires are not uncommon in an installation. New microcomputerized controls, sophisticated detection devices, methods of alarm reporting, and operating features unheard of a few years ago demand that those already in the industry continue to advance their skills and that those seeking to enter this job market learn the necessary technology. Part I introduces the basic principles of electricity to get the newcomer started. The material relates directly to actual alarms systems, not general theory. Part II provides specific guidelines for identifying and troubleshooting problems associated with equipment, loops and wiring. Part III explains how to service simple alarm hardware such as controls, silent alarms and local bells and batteries. Part IV progresses to the more advanced intrusion detection systems, including ultrasonics, microwave, passive infrared, and sound detection systems. Part V examines the practices of the alarm business, emphasizing the need for safe work habits and effective customer communication. A comprehensive glossary rounds out this highly useful guide. This second edition is invaluable to anyone who wants to understand, specify, install, or repair alarm equipment or systems. It provides a thorough understanding of how alarm systems work, what can go wrong and how to fix them by using proven tools and techniques.
