Page 22: Chapter 3 Digital Infrared Radiator
Chapter 3 Digital Infrared Radiator 3.1 Overview The radiator is high power IR radiating equipment used to receive the carrier wave signal from the IR system controller and emit the signal in the form of IR. It support hand-in-hand connection and there can be maximally 30 radiating panels connected together. -

The value for adjusting will be displayed on the LCD above the button. - Page 24 If the radiator are installed highly enough, the signal intensity of the received IR signal will not decreased to zero in the shadow area, because IR can be reflected (same as the visible light). Fig.3-1 Square IR coverage When the radiator cannot be installed onto the existing ceiling, walls or bearing structures, they must be installed according to the above mentioned rules to ensure the proper signal transmission.

Page 25: Wiring Of The Radiator
Fig. 3-3 “IR Coverage in “blind Area” 3.4.2 Wiring of the radiator The signal’s delay can be caused by the distance difference between the system transmitter to the different radiator. In order to avoid “blind spot” , please choose the cables that are of same length. -
Page 26: Rectangle Coverage
3.4.3 Rectangle Coverage The actual required number of the radiator can only be determined by field test, but using “rectangle coverage” can ensure a very close guess. Fig.3-6 and Fig.3-7 explain what is the “rectangle coverage”, from which we can see that the rectangle coverage is smaller than the total coverage. -
Page 27: Delay Switch Settings
3.6 Delay switch Settings In section 1.4.6, there is “overlapping multi-path effect”: the receiver receive signal from two or more radiating panels, and “blind spots” can be caused due to delay difference. In order to compensate the delay difference, the delay switch on the side of the radiator can be set to increase the corresponding panel’s delay. -
