Foreword These guidelines cover the proper
41、 physical installation of nurse call systems. This publication describes system types, the basic theory of operation, the use of ancillary devices, installation requirements, the isolation of circuits, system environmental considerations, inspection, testing, maintenance, and service. The content wi
42、ll be helpful to those preparing for proficiency or certification in the design, installation, ser- vice, and maintenance of nurse call systems. Although it has been written primarily as a stand-alone guide, it can also serve as a text for apprentices and journeymen taking a class with a qualified i
43、nstructor. The publication emphasizes the installation of basic nurse call systems. For information on applying the myriad choices of systems or equipment available, the reader should follow the specific instructions pro- vided by the manufacturers. The information is presented as Authorized Enginee
44、ring Informationa technical guide, as distinct from the mandatory requirements of a NEMA standard. This publication will be updated to keep abreast of new technology and the new requirements set forth in the referenced publications of other organizations. This Installation Guide for Nurse Call Syste
45、ms is published by the National Electrical Manufacturers Association (Signaling, Protection, and Communication Section -3SB). About the NEMA Signaling, Protection, and Communication Section (3-SB): The objective of the Section is to be the principal source of technical, training, and educational mat
46、erials essential for the specification and manufacture of reliable life safety products, their installation, perform- ance, and inspection. The Section currently represents over 40 U.S., U.K., and Japanese manufacturers. The products are life safety/fire alarm products that provide early warning of
47、an impending or actual fire or gaseous hazard as well as communications systems in health care facilities, such as hospitals, clinics, etc. The products detect, notify, and initiate control functions in case of hazard to life or property. About the National Electrical Manufacturers Association (NEMA
48、): For more than 75 years, the National Electrical Manufacturers Association has been developing stan- dards for the electrical manufacturing industry and is today one of the leading standards development organizations in the world. NEMA contributes to an orderly marketplace and helps ensure the public safety. NEMA, with headquarters in Rosslyn, Virginia, has nearly 500 member companies, including large, medium, and small businesses. The organization is divided into eight divisions: Industrial Automation, Lighting Equipment
