LightMaster-4 (LM4) Lighting Control Panel

ILC´s smallest LightMaster Lighting Controller, the LM-4, is a compact and powerful lighting control panel designed for distributed mount applications. This panel will easily integrate into the LightMaster Standard or Expanded Network application. Every LM-4 Lighting Controller is equipped with standard CAT-5 RJ-45 connectors to integrate easily with ILC´s data line. The LM-4 also features an additional CAT-5, RJ-45 connector for local switches, photocells and other LightSync devices.

Relay Groups

  • Relays may be assigned to any of 48 available groups
  • Relay groups may be assigned to multiple Timers, Switch Inputs, and other panel functions

Relay Presets

  • Relays may be programmed to any of 48 presets available
  • Presets may be controlled by Switch Inputs and Timers

Open/Close Times

  • Lighting Control Schedules may adjust based on business (retail) Open/Close hours for easy adjustment when operating hours fluctuate
  • Seven standard Open/Close times and 365 custom daily Open/Close times available
  • Scheduled event may be programmed to occur before, after or at Open/Close times

Relay Functions

  • Each relay may be programmed for ON only, OFF only or ON/OFF control
  • Pulsed output for control of external devices such as lighting contactors or other systems
  • HID multilevel control (specialized output control for multilevel HID ballasts including warm-up sequence)

Switch Types

  • The LightMaster may be programmed to accept virtually any type of switch input, momentary or maintained

Switch Input to Relay Output Mapping

  • LightSync switch to relay settings are completely soft, requiring no field rewiring when changes are required
  • Any LightSync switch control any combination of relays, groups or presets locally and across the network

Automatic Power-Up Settings

  • Relays may be programmed to automatically turn to ON, OFF or remaining in the state they were in prior to the outage

After Hours Sweeps

  • Individual relay or groups of relays may be programmed to be swept OFF during non-operational hours
  • After hours OFF Sweeps can be set to occur based on time window

Astronomical Clock

  • Automatic calculation of Sunrise and Sunset based on date and geographic position
  • Scheduled events may be programmed to occur before, after or on an astro event

Blink Alert

  • Prior to a scheduled OFF event, lighting loads programmed for a Blink Alert will be momentarily turned OFF then back ON to alert occupants. To avoid the pending off sweep, the user simply turns their local switch OFF and then back ON again during the adjustable period (default is 5 min.) prior to the OFF sweep
