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 set to adjust based on business (retail) Open/Close hours
  • Standard daily and weekly Open/Close times and 365 custom daily Open/Close times
  • 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 (output control for multilevel HID ballasts including warm-up sequence)

Switch Types

  • The LightMaster accepts virtually any type of switch input, momentary or maintained
  • Easy direct connection to motion and photo sensing devices
  • Override inputs can enable or disable any relay or group of relays
  • Input disable based on time of day

Switch Input to Relay Output Mapping

  • All switch to relay settings are completely soft, requiring no field rewiring when changes are required
  • Any switch can control any combination of relays 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

Daylight Saving Time Adjustment

  • Automatic adjustment for daylight saving changes (may be enabled or disabled from keypad or software)

Astronomical Clock

  • 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.
