3 Introduction This specification was prepared to establish and promote uniform requirements for Meter Data collectors. The specification lays down the minimum requirements for equipment acceptable for evaluation. It is the responsibility of the Manufacturer/Suppler to familiarize himself with the standards referred herein. This specification is in two parts, one is a narrative clause-by-clause and the other is a summarized table of the same clauses located in the specifications and marked as Appendix B. Tenderers shall complete the schedule in Appendix B and this shall form the basis for the technical evaluation of their tender (See clause 4.5.4). Appendix A is a snapshot of the technical data and tenderers shall indicate conformance or state any deviation from these requirements. 1. Scope (a) This specification is for newly manufactured Stand-alone and internally fitted Energy Meter Data Collectors for use in an Automatic Meter Reading (AMR) system. (b) The details of the types of meters and the AMR system to be used are specified in separate documents. 2. References The document, IEC : , Telecontrol equipment and systems Part 5: Transmission protocols, was referred to during the preparation of this specification. In case of conflict, the requirements of this specification take precedence. 3 Terms and definitions For the purpose of these specifications, the following definitions and those specified in the IEC : shall apply: AMR meter data collector Page 3 of 10

4 3.1 Automatic Meter Reading (AMR): The technology of automatically collecting data from energy metering devices and transferring that data to a central database for billing and/or analyzing. 3.2 Meter Data Collector: This is a device that collects data from energy meter or from a central master station and transmits it to a central master station or to an energy meter. 4 Requirements 4.1 Operating Conditions requirements The meter Data Collectors shall be suitable for operation in tropical climate where temperatures may vary from -1 to + 45 degrees Celsius Average Annual Relative humidity reaching 90% and altitude of up to 2,200m. 4.2 Design and Construction requirements The Data collector shall be stand-alone device separate from the Energy meter The stand alone Data collector shall be connected in a meter board.
