ESLS Sensors and Controllers
A typical layout of Systel's Energy Saving Lighting System (ESLS), shown in Fig. 1, includes the following Systel elements:
- Controllers:
- Lighting Control Panel (LCP)
- Wall Control Unit (WCU) and hand-held remote control
- Multiple Network Sensor Unit (MNS)
- Sensors:
- Occupancy Sensor
- Light Sensor
- Inputs for additional sensors (e.g., temperature, door closure, humidity)
- Systel Electronic Ballasts

ESLS Technology Highlights
- Error-free, two-way power line communications (PLC) in ballasts and controllers, implemented using Systel’s IDC2000 power management ICs.
- No additional control wiring - no modification of existing wires and simple to install.
- All devices are individually addressable throughout a building or campus.
- Fan and HVAC control can be provided by actuators in WCU or MNS units, based on temperature sensors.
ESLS is a fully Distributed system: each branch (each corresponding to a circuit breaker panel) can be fully autonomous, that is, independent of ELSL lighting control panels (LCPs). Devices within a branch can also interoperate with others in a different branch via BRCU gateways (located in the LCPs). Each device within any branch can interoperate with the BMS to receive commands for load shedding or to send status for maintenance.
This approach, enabled by the IDC2000 embedded IC’s, provides rapid, robust communications and simplicity of commissioning, all at a low cost.
