The standards do not cover electronic building automation and energy management systems, outdoor perimeter intrusion detection systems, and fire detection or suppression systems. The standards were developed to guide Park Services engineers and others who plan or supervise the installation of intrusion detection systems. Such systems are installed in new buildings as they are constructed and in existing buildings. The standards do not provide instruction on how to design an alarm system nor can they be used to decide what components to include in an alarm system. They will be most useful when preparing plans and specifications for systems to be procured by the competitive bidding process. Under general provisions, the standards state that alarm systems shall comply with all applicable Federal, State, and local building, electrical, and safety codes, and all materials and equipment installed shall conform to the standards of Underwriters Laboratories, Inc. or other similar nationally recognized testing organization. Other general provisions deal with Federal specifications, departure from standards and specifications, standard products, product quality, and capabilities of the alarm contractor. Other topics covered in the standards are system philosophy, planning and layout, system wiring, controls and control cabinet, authorized access and shunt switches and access controls, detectors and sensors, and local alarm signaling devices. Other standards topics include telephone dialing and reporting devices, monitoring units for proprietary alarm systems, false alarms, and documentation and training. Eight references are listed.
