IRW-1S INFRARED (IR) SENSORS (1) (1) IR Receptor (2) Power LED (3) Wall Mounts (2) (3) IRW-1S INFRARED (IR) SENSORS 1. Operation The IR Sensors act as "antenna" for your infrared wireless microphone system. A multiple array of wide angle IR-sensitive LED's, behind the front panel receptors, receives the infrared signal emitted by your IR transmitter. The Sensor Power LED (2) will light to indicate the sensor is properly connected to the IRW-220X Receiver. The Channel A and B IR LED indicators, located on the front panel of the receiver, will light green when an infrared signal on the corresponding channel is detected. 2. Installation The IRW-1S sensors can be mounted on walls using any of the Wall Mounts (3) included. To ensure proper optimum operation, observe the following installation rules: a. Position the IR Sensors with their front panel receptors facing the entire area of transmitter operation. If this is a wide area, angle the receptors to cover the maximum area range. The diagram on the opposite page shows a suggested positioning for the IR Sensors. Note: The IR sensors will need to be positioned differently for each environment. During installation, power up the IRW-220X and have one person walk around the desired location, with the transmitters on, while another person positions the IR Sensors for greatest range of mobility. 6 b. Since the unit utilizes infrared light reflected off of room surfaces, do not mount the sensors near a black ceiling, wall, or heavy curtains as they may limit the range by eliminating such reflection. Mounting the sensors in an uncluttered area near a light colored wall will provide the best operation. c. Although the unit can be used in most brightly lit rooms, it works best if bright lights are not shined directly on the sensors. (Note: Never operate the unit outdoors in daylight as it will not operate properly under such conditions) d. Never cover the IR Sensors as this will disrupt normal operation. If they become dirty, clean with a soft cloth. Make sure the sensors are not obstructed and always have a clear line-of-sight with the transmitters. 3. Additional external IR sensors can be added using the IRW-SA Multiple Sensor Adapter which allows multiple sensors to be connected to each input. 7
