CHAPTER 1: OVERVIEW
1.2 Applications
1.2.1 Stand-Alone Meter
The GE Energy EPM 1500 can be installed as a stand-alone device that is locally accessed
via the LCD or remotely accessed via modem. A modem can be installed in each meter
allowing the meter(s) to be read remotely.
1.2.2 Metering System
The GE Energy EPM 1500 family of meters are ideally designed to comprise a metering
system within a residential/commercial building or industrial site. This metering system
can measure electrical usage for each tenant, cost center, or common area space and
communicate this information over the building's power wires or dedicated
communication wiring (RS485). A metering system is comprised two or more EPM 1500
meters and a communication transponder (see figure below). The transponder collects all
of the metering data via the AC power lines and communicates data to an optional
transponder.
