The systems may be classified as either standard line security equipment or encrypted line security equipment by virtue of the construction and performance requirements for components of that system. However, requirements covering the complete systems are contained in the Standard for Central-Station Alarm Services, UL 827.1.4 Protective devices installed on individual properties are further classified as to extent of protection at each location, according to the requirements covering installation and classification (of extent) of alarm protective equipment at individual locations as published in the Standard for Installation and Classification of Burglar and Holdup Alarm Systems, UL 681.1.5 If equipment covered by these requirements is intended for use in a combination burglar-alarm and fire-protective signaling system, the portion of the equipment serving a fire-alarm function is covered by the Standard for Control Units and Accessories for Fire Alarm Systems, UL 864.1.6 Systems covered by these requirements operate using Class 2 remote-control and signaling circuits as defined by Article 725 of the National Electrical Code, NFPA 70.1.7 The requirements assume that standard telephone operating practices are acceptable for leased or other lines connecting to a central-station as defined by Article 800 of the National Electrical Code, NFPA 70.
