Intended Use

KiloWatch® dual-level HID luminaire option provides capability to switch ballast between high-mode and low-mode operation. Choose from 100% to 50% power operation or 100% to 50% lumen output operation. Luminaires must be combined with motion sensors, photocells and/or control transformers for complete system. Ideal for energy reduction or light level control in warehouses, storage areas, parking garages, shipping docks and gymnasiums.

Construction

Components:

KWTD: Time delay control. Solid-state, digital timing circuit automatically provides high mode start-up of each lamp for 15 minutes, guaranteeing lamp stabilization. For 120V AC manually switched or 120V AC photocell (KWPC) applications.

KWTXTD: Time delay control voltage transformer. Provides 120V AC control circuit power for 208/240/277/347/480V AC applications controlled by photocells or manual switching*. Includes solid-state, digital timing circuit for automatic high mode start-up of each lamp for 15 minutes, guaranteeing lamp stabilization. One KWTXTD required for each on/off control zone of up to 30 fixtures.

KWTX: Control voltage transformer. Provides 120V AC control circuit power for 208/240/347/480V AC applications in conjunction with KWIR motion sensors. High mode start-up of each lamp for 20 minutes performed by KWIR sensors. One KWTX required for each on/off control zone of up to 30 fixtures.

KWIR: Passive infrared motion sensor. Switches 120V or 277V control relays in each lighting fixture based on occupancy. Sensor detects moving temperature differentials against background radiation. When motion is detected, lighting system is switched to high mode for one to 20 minutes (field adjustable) after motion no longer is detected. Sensor includes timing circuit for automatic high mode start-up for 20 minutes. Sensor is factory-preset at optimum performance angle (43°) and can be field-adjusted. Sensor is designed for use in indoor applications with 15' to 35' mounting heights where a long and narrow coverage pattern is desired (14°F to 160°F).

KWIR WA: Passive infrared motion sensor. Same as KWIR sensor with wide angle lens designed for use in indoor applications with 7' to 8' mounting heights where a short, wide coverage pattern is desired (14°F to 160°F).

KWIR LT: Passive Infrared motion sensor. Same as KWIR sensor designed for low temperature operation (-40°F to 160°F).

KWPC: Photo-diode sensors. Sensors switch luminaires to low output based on predetermined ambient illumination levels (field adjustable).

Luminaires:

KiloWatch options listed below only are available with CWA/SCWA ballast configurations. The desired option must be designated in the fixture catalog number.

KW1: Reduces wattage by 50% (light output reduces by 70-80%). Luminaire supplied with 120V AC control components for use with all manually switched*, KWPC photocell (120/208/240/277/347/480V) or KWIR sensor (120/208/240/347/480V) controlled systems.

KW150: Reduces light output by 50% (power reduces by 30-40%).Luminaire supplied with 120V AC control components for use with all manually switched*, KWPC photocell (120/208/240/277/347/480V), or KWIR motion sensor (120/208/240/347/480V) controlled systems.

KW4: Reduces wattage by 50% (light output reduces by 70-80%). Luminaire supplied with 277V AC control components. For use with KWIR motion sensor controlled systems.

KW450: Reduces light output by 50% (power reduces by 30-40%). Luminaire supplied with 277V AC control components for use with KWIR motion sensor-controlled systems.

Consult factory when using RELOC® wiring with KiloWatch®.

Lamp manufacturers require 100 hours high-mode burn-in of new lamps prior to low-mode operation and 15 to 20 minutes of high-mode operation thereafter upon start-up.

Not for use with dual-wattage-rated lamps.

* Manual switches and wall boxes by others.

Consult factory for field start-up service.
