  • SCOPE

    1 Scope

    1.1 These requirements cover closed-circuit television equipment that:

    a)    Are intended for commercial use on supply circuits as defined in the National Electrical Code, NFPA 70; and

    b)    Receive their signals from a video-recorded medium or image-producing devices in a closed-circuit television system.

    1.2 These requirements cover closed-circuit television equipment – such as video tape recorders; video-receiving, -processing, -recording, -producing, and -amplification equipment; video cameras; and the like.

    1.3 These requirements also cover auxiliary equipment and accessories intended for use with closed-circuit television systems.

    1.4 These requirements also cover portable closed-circuit television equipment of the types described in 1.2 that are intended for use with a vehicular, marine, or any other battery circuit as the power supply means.

    1.5 These requirements do not cover video monitors, as these products are covered by the:

    a)    Standard for Audio-Video Products and Accessories, UL 1492;

    b)    Deleted

    c)    Deleted

    d)    Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1.

    1.6 These requirements do not cover video cameras with integral electronic viewfinders.

    1.7 These requirements do not cover tape-head demagnetizers or bulk tape erasers intended for use with video products and do not cover general-purpose tape-head demagnetizers or bulk tape erasers, as those products are covered by the requirements for household and commercial tape recorders in the Standard for Audio-Video Products and Accessories, UL 1492 and the Standard for Commercial Audio Equipment, UL 813.

    1.8 Commercial video products provided with a means for receiving commercially broadcasted video signals and household video products are covered by the Standard for Audio-Video Products and Accessories, UL 1492.

    1.9 A cart or stand that is not intended to be used with a specific product is covered by the Standard for Household, Commercial, and Professional-Use Carts and Stands for Use with Audio/Video Equipment, UL 1678.
