8 models of meter registers? How and where is this accomplished? Are different MIUs required for different makes and models of registers? If so, how are these distinguished? [COMPANY] insists that one MIU model accommodate five (5) or more meters by a different brand manufacturer. Batteries [COMPANY] requires a LoRaWAN system that gives them the ability to choose between utilizing the MIU warranty or performing battery changes on their own should battery failures occur. How are battery changes performed within the MIU should failures occur? What type and size of battery does the MIU use? What is the expected battery life when the MIU is used with normal or default settings? Describe the expected battery life as a range of years within two standard deviations of the average expected life. How will the system prevent loss of programming or data if the battery expires? Does the AMI system provide a warning well in advance of battery failure? If so, what is it and how is this accomplished? Is battery life affected by the type of meter register the MIU is reading? If so, indicate the differences in expected and guaranteed lives. Battery life of the MIU must be warranted for a minimum of twenty (20) years (10 years full and 10 years prorated). Conditions of warranty shall be included in the proposal. With an understanding of how proration curves work and that the main source of failure within an MIU is battery related, [COMPANY] requires that the MIU and infrastructure equipment have a battery that is removable and replaceable. All systems that have not been designed around, and have the capability for, field replacing of the battery will be considered unresponsive. What is the current cost of replacement batteries? Can the battery be replaced in the field? Does battery replacement require soldering or special tools, or the application of any sealant? Describe any special MIU battery disposal provisions and indicate the current cost of providing battery disposal if special handling is required. ID Number Each MIU shall have a unique, permanent ID number that is transmitted with the meter readings. This serial number shall be readable on the outside of the unit as well as being bar- coded. Programmability The MIU should be able to be initialized or programmed during or prior to field installation. Describe all MIU programming options, features, and procedures. Can the MIU store a meter register number or additional account number? Will this number be transmitted with the meter reading data? Can this number be programmed into the MIU from a field programming unit based on information downloaded from an installation work order database? What other data are or can be stored in the MIU? Describe capabilities and procedures. [COMPANY] requires that the MIU must be capable of storing and holding hourly data for a minimum of three hundred sixty-five (365) days. Tampering Describe features, including physical characteristics (seals, tamper-resistant bolts, etc.), to minimize, detect, and report tampering with the MIUs. Environmental Tolerance Describe features of the MIU that prevent corrosion or degradation of mechanical or electrical performance (e.g., encapsulation or coating). The MIU must operate in conditions subject to water submergence (i.e., meter vaults). The MIU enclosure should be composed of ultraviolet
