Low Voltage Wiring Security Fire Alarm Systems by Terry Kennedy and John E. Traister


In general, an alarm system is used to protect life and property. Therefore, any company or person who owns something of value has a valid interest in security and fire-alarm systems. Security and fire-alarm systems are designed for every application imaginable for structures as small as homes and roadside produce stands; large hotels and factories; security alarms for guarding automobiles; large national defense installations—the list is very long. And this book is designed to review the various security systems currently available to help the reader select the most appropriate system for the job.

This new edition adds a first part that surveys the business of security systems and computer information for the professional. It also includes a nutsand-bolts survey of how to start or grow a business, and how to work in other areas of the low-voltage systems industry. It then covers installation methods, techniques, and requirements to comply with the 1999 National Electrical Code. Part 3, A Deeper Understanding, reviews electrical circuits, the code, and print reading in depth.

The new edition also features a twenty-first-century Reference Section that guides the reader into a listing of references for information to be found on the Internet. To move fully into the new millenium, we have included a compact disk. The checklists in the reference section can be accessed simply and quickly from your own computer. The abundance of solid information makes this book invaluable to anyone involved with security and fire-alarm systems. 

Overview of a Contract Service Business 

The nature of most businesses related to the AEC (Architecture, Engineering, Contracting) industry is that profits are based on the development and performance of contracts. Many deals related to other types of business involve some variety of an agreement document, but construction industry contracts require complex participation from all parties: the principal customer, the design and engineering team, the general contractor, the subs, and the materials suppliers.

As we all know, a site is chosen and a design team works with the principals to develop the earth and the built structures to skillfully achieve the goals of the owners. Naturally, the intention of the construction team is to produce the product that the architects and engineers have designed, to enjoy the sense of a job well done, and to make some money. Many enterprises, like retail manufacturing or food services, allow the businessperson to select or design the product, then manufacture and sell it in a protected environment.

For example, a bag of chips can be produced in a factory and the production process can be sheltered from the elements and a great deal of the work can be thoroughly boiler plated. Thus, the profits and future of the business can be predicted in some detail. Naturally, there will be swings: potatoes or corn crops might suffer from the weather, transportation costs might fluctuate, the customer base might tighten up, but basically an entrepreneur in these enterprises has a good deal of control over the process of providing for their clientele.
