Wired Sensors EC-DIR-WH Daylight Sensor 369457e 1 10.01.20 Wired Daylight Sensor with Infrared Receiver This daylight sensor is designed specifically to work with Lutron ballasts, control modules, and sensor interfaces to implement daylight harvesting. To maintain a specific light level in the space, it allows the control system to automatically dim the lights when the available daylight is high and brighten the lights when the available daylight is low. An integrated infrared (IR) receiver resides within the sensor to allow access to the system for advanced programming and personal control. Features • Mounts easily on any ceiling tile or fixture. • Threaded mounting stud may be shortened for applications with limited fixture height. • Calibrated for daylight sensitivity through the lighting control system to which it is attached. • Receives IR signals and transfers them to a digital ballast, control module, or sensor interface. • The infrared receiver receives IR programming signals from up to 8.2 ft (2.5 m) away. • Constructed of flame-retardant material. • Meets IEC 801-2. Tested to withstand 15 kV electrostatic discharge without damage. • LED indicates programming mode. • Sensor wire insulation is rated to 600 V, suitable for fixture installation. ® SPECIFICATION SUBMITTAL Page 1 Job Name: Model Numbers: Job Number:

Wired Sensors EC-DIR-WH Daylight Sensor 369457e 3 10.01.20 Mounting and Wiring Installing Arrow points toward the area Determine the Proper Location of the Daylight viewed by the sensor Sensor Using the Adjacent Diagram. • The arrow on the daylight sensor points toward the Bottom of sensor area viewed by the sensor. • The effective window height (H) starts 3 ft (1 m) up 1–2 H from the floor or at the window sill, whichever is higher, and ends at the top of the window. • Place the daylight sensor so its viewing area is 1–2 H centered upon the nearest window at a distance of between 1–2 H from the window. 3 ft (1 m) • Ensure that the view of the daylight sensor is not obstructed. H = Effective Window Height • Do not position the daylight sensor in the well of a skylight or above indirect lighting fixtures. Mounting the Daylight Sensor • Drill a 3/8 in (10 mm) diameter hole in the ceiling tile or pendant fixture. • Thread the wires through the hole. • Install the daylight sensor into the hole. • Secure the daylight sensor with the mounting hardware provided (hand tighten only). Note: If the stem of the daylight sensor must be shortened because of its location (e.g., in a pendant Pendant Fixture Ceiling Tile or Fixture fixture), this should be done prior to wiring. Wiring to a Sensor Input • Connect the sensor wires as described: Wire Terminal Red 20 V- Cap-off if Black Common not used 2 Yellow Daylight Signal 22 AWG (1.0 mm ) solid only White/Red* IR Signal (cap if not used) Wired Daylight Sensor • Make sure that the supply breaker to the control with IR receiver system is OFF. 2 * The red stripe on this wire may be absent in older products or • Use only 22 AWG (1.0 mm ) solid wire. in retrofit applications. • If IR output is not required, the white/red* wire should be terminated. • A sensor can be wired only to a single control module or sensor interface. Lutron is a trademark or registered trademark of Lutron • Each input on a control module or sensor interface Electronics Co., Inc. in the US and/or other countries. can have only one daylight sensor connected to it. ® SPECIFICATION SUBMITTAL Page 3 Job Name: Model Numbers: Job Number:
