    Definition
  • Specifies the general requirements for equipment used in alarm transmission systems. Does not specify the equipment used to display the information at the alarm receiving centre or the installation of the equipment.
  • Specifies the requirements for alarm transmission systems using dedicated alarm transmission paths which are additional to those specified in IEC 60839-5-1 and IEC 60839-5-2. Covers dedicated connections providing signalling continuity between an alarm system and the presentation of alarm(...)
  • Specifies the requirements for digital communicator systems using the public switched telephone network which are additional to those specified in IEC 60839-5-1 and IEC 60839-5-2. Covers switched connections providing event driven signalling between an alarm system and a remote centre.
  • Specifies the requirements for voice communicator systems using the public switched telephone network which are additional to those specified in IEC 60839-5-1 and IEC 60839-5-2. Covers switched connections providing event driven signalling between an alarm system and a remote centre.
  • Describes the requirements for standard serial data interfaces in alarm transmission systems. Gives an outline of how alarm transmission systems are connected and the various types of serial data interfaces that might be employed.
  • Specifies a common application layer protocol (message structure, formats and transmission procedures) to be used at standard interfaces in alarm transmission systems. Should be used at all such interfaces where equipment from one supplier is intended to inter-work with equipment from other(...)
  • Specifies the data link layer message structure, formats and transmission procedures which should be used at standard serial data interfaces in alarm transmission systems where the transmission network employed does not offer a standard protocol.
  • Specifies the transport layer message structure, formats and transmission procedures to be used at standard interfaces in alarm transmission systems.
  • Specifies the requirements for standard interfaces using a two-wire connection employing ISO/IEC 8482 signalling for use between the control and indicating equipment of an alarm system and one or more alarm system transceivers connected to alarm transmission systems.
  • Specifies the requirements for standard interfaces employing ITU-T V.24/V.28 signalling for communications between the control and indicating equipment of an alarm system and transmission equipment used for remote communications, where the transmission equipment is general purpose equipment.(...)
  • Specifies the requirements for standard interfaces between the control and indicating equipment (CIE) of an alarm system and an alarm system transceiver where the alarm system transceiver is intended to plug into a standard space inside the CIE of the alarm system.
  • Specifies the requirements for standard interfaces between the Public Switched Telephone Network (PSTN) and alarm system transceivers. Specifies a 1 200 baud interface using ITU-T Recommendation V.23.
  • Specifies the requirements for standard interfaces between the alarm system transceivers and transmission network where both form part of a dedicated channel alarm transmission system as defined in IEC 60839-5-4.
  • Specifies the requirements for standard interfaces between the terminal transceiver of an alarm transmission system and the annunciation equipment. Employs signalling in accordance with ITU-T Recommendation V.24/V.28.
  • Specifies requirements and test methods for vehicle security alarm systems in tended for installation within vehicles used for the carriage of passengers and having not more than eight seats in addition to the driver's seat.
  • Specifies the minimum functionality, performance requirements and test methods for electronic access control systems and components used for physical access (entry and exit) in and around buildings and protected areas.
  • Specifies the design requirements and the performance characteristics of dose equivalent (rate) meters intended for the determination of ambient dose equivalent (rate) and directional dose equivalent (rate) as defined in ICRU Report 47.
  • Applies to portable or transportable dose equivalent (rate) meters and/or monitors for the measurement of ambient and/or directional dose equivalent (rate) from external beta, X and gamma radiation during emergency situations.
  • Applicable to insulating foam-filled tubes and solid rods, of a circular cross-section, made of synthetic materials and intended to be used for the manufacture and construction of tools and equipment for carrying out live work on electrical systems operating at voltages above 1 kV.
  • Applies to equipment intended to detect ionizing radiation from, and provide warning of, a criticality accident. Specifies the general characteristics, operating characteristics, electrical, mechanical, safety and environmental characteristics, test procedures and documentation.
