AMRS Meter Specifications v.12.4.18 Appendix 3

1.0 AMRS Electric Meter Specifications

The AMRS Compliant Electric Meter shall meet Department of Defense cybersecurity in addition to the following requirements:

Current Inputs:

Nominal 5A (Class 0.2s) Measured Current: 50mA to 10A Withstand: 20A Continuous Poly Phase (3 voltages and 3 currents) Internal storage for recording 2 values or channels for 90 days, configurable using manufacturer supplied configuration software. Must support interval consumption (15 minute) and demand (15 minute block average)

Clear and concise manufacturer’s published procedure or method for extracting the internally recorded values, register sets (buffer) or channel data via Modbus and Ethernet

Shall support time of use recording Onboard ethernet communications, base 10/100 with RJ45 connector or pigtail with receptacle connector Modbus/TCP communication protocol is required.

Front display with ability to display all measured values Minimum of two external dry contact inputs that shall count pulses from other devices Minimum of one (1) external RS485 serial port The above requirements are for new, electric meter installations.

Firmware version must be approved in the AMRS ATO, contact Contracting Officer to request approved version upon award

Meter shall have control power regardless of breaker position

1.1 New Meter Installations

All new meter installations shall be provided with voltage and current safety disconnect devices or equivalent so that the meter assembly can be worked on safely over the life of the meter installation and not require utility outages for servicing. All new meter installations shall include the installation of new properly sized split or solid core current transformers (CTs). All new meter installations shall be connected from the meter, to a RJ45 jack in the mechanical room, to a patch panel in the communications room, and then to the Air Force switch in the communications room.

Base communication installation guidelines shall be followed at all times. The final connection to the Air Force switch may have to be performed by the base communications organization. In that event, three (3) feet of additional communications cabling shall be left for the third party to make the final connection.

1.2 AMRS Compliant Meter List

The following list of meters were evaluated, meet the AMRS meter specification and shall function within the AMRS platform.

Class “I” Meters- Service entrance of more than 800A, buildings sensitive to power quality, or buildings requiring detailed characteristic analysis.

AMRS Meter Specifications Appendix 3

Electro Industries Nexus 1500+ Schneider Electric ION 8650 Schneider Electric PM8000

Class “II” Meters- Service entrance of 400-800A, or buildings with stable power quality.

Electro Industries Nexus 1272 Electro Industries Nexus 1262 Schneider Electric PM5560

Class “III” Meters- Service entrance of less than 400A, reimbursable buildings, or no concern with power quality.

Schneider Electric PM850SD

2.0 AMRS Compatible Gas Meter Specifications

AMRS compatible gas metering solutions consist of a componential system to achieve the goal of delivering gas consumption data into the AMRS. To accurately scale output pulses the contractor shall obtain building gas usage from base personnel, taking into account peak demand when sizing the components that are necessary as well as determining peak pulse rate as to not saturate the receiving device and risk losing captured pulse data. The various components that may be necessary include but are not limited to the following: Gas Meter, Pulse Kit, High Speed Dividing Pulse Relay, Surge Suppresion Device, Accumulator, Electric Meter with digital input availability. All exterior to interior communication links shall have surge suppression.

Pulse kit must be able to produce a two-wire (Form A) pulse output Pulse output shall be delivered to a high speed dividing pulse relay that has the capability of producing a wetting voltage if necessary High speed dividing pulse relay shall provide isolated pulse outputs (Form A) that shall be delivered to an AMRS compatible electric meter In the event a facility does not have a compatible AMRS electric meter, a high speed dividing pulse relay shall provide isolated pulse outputs (Form A) that shall be delivered to an accumulator that speaks the Modbus protocol natively and can communicate to AMRS via the Modbus/TCP protocol

Gas Meters that can communicate to AMRS via the Modbus/TCP protocol may be acceptable if they can pass technical and cybersecurity evaluations directed by the AMRS PMO. At this time there are no tested or approved Modbus /TCP gas meters

3.0 AMRS Compatible Translation Devices and Accumulators

3.1 The following devices are compatible with the AMRS platform, are consistent with the need of the existing site conditions, and have been tested and passed cybersecurity requirements:

Advantech ADAM-6051 I/O Modbus TCP Module with firmware v5.04 B01 Perle IOLAN SDS1P Serial to Ethernet Device Server with firmware v4.6 F1
