NRIWS270001Line Voltage Dual-Tech Dimming Wall Switch Sensor

INTRODUCTION The LDD-700 is a line voltage dual tech (PIR & HFD) wall switch sensor with 0-10V dimming output that not only can automatically turn lights ON/OFF based on occupancy or vacancy sensing control, but also allow the user to manually adjust the lighting level as required. The LDD-700 will automatically turn ON the light at set-level (factory set 100%) for a period of delay time when it detects the presence of an occupant. If no motion is detected before the delay time elapses, the sensor will turn OFF the light. It can be set as a vacancy sensor which will only turn ON the light at set-level by pressing any push-button, and then automatically control the light in the same way as above described. Two push-buttons allow the user to change ON-OFF status, adjust lighting level as desired, or memorize the preferred level for the next presence. Two Accu-Set potentiometers offer fast, easy and accurate settings for delay time (TIME) and ambient light level (LUX). A 5-pole DIP switch can be set to adjust the HFD sensitivity, disable the PIR sensor, operate as a vacancy sensor, and set the push-button operation control.

DO NOT control a load in excess of specified ratings to avoid damaging the sensor or the property. Install and use this sensor in accordance with electrical codes and regulations. This device is intended to be installed by a qualified electrician. DO NOT attempt to service or repair. Install the sensor at least 1ft. away from any occupant. Afin d'eviter tout risque de choc electrique ou electrocution, couper le courant au disjoncteur avant installation, remplacement des lampes ou tout service d'entretien. NE PAS contrôler une charge supérieure à la capacité spécifiée pour éviter d'endommager le capteur ou la propriété. Installer et utiliser ce capteur conformément aux codes et règlements électriques. Ce dispositif est destiné à être installé par un électricien qualifié. NE PAS tenter de réparer. The sensor is more sensitive to the movements “crossing” the detection zones than “toward” or “away” it. To obtain optimum sensitivity, ensure the sensor to always have clear field of view for the occupant’s motion within the desired detection coverage. In general, the HFD sensor has better sensitivity to the minor motions than the PIR sensor. Also the HFD sensor could possibly detect out-of-sight movements through non-metallic partition or enclosure. If so, reduce the HFD sensitivity to prevent detecting the activities of adjacent areas which may result in unneeded lighting. Avoid mounting the sensor behind the door, partition, plant, or furniture. As a general rule, every occupant within the desired range should be able to “see” the sensor. Do NOT mount the sensor nearby a heat source, or at the place where it can “see” the unintended motions (e.g. hallway traffic). 1. 2. 3. 4.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
