Radio outer transmission module 2 channels. LxWxH: 60x46x30mm (dimensions without screwing). With inner antenna. No standby loss. The radio transmitter module has two channels and can thus send radio telegrams into the Eltako building radio just like a radio switch. A1 triggers a radio telegram such as pressing the rocker on the top of a radio button with a rocker and pressing A3 like the rocker on the bottom. Release the telegram when the two control contacts are opened is identical to that of the radio button. You may not control several wireless transmitter modules at the same time. For the IP54 waterproof connection, there is a screw connection M12 on the bottom. Connection to an inner 5-way terminal for the control inputs +A1/-A2 and +A3/-A2. To do this, loosen the two screws on the front and remove the cover. If terminals A1 and A3 are connected with a bridge, a radio telegram from A3 is transmitted 1x per minute as long as the control voltage is applied. FOR EXAMPLE, for priority central commands. The universal control voltage processes control commands from 8 to 253V AC or 10 to 230V DC with a length of at least 0.2 seconds. The maximum parallel capacitance of the individual control cables (separately laid) is 230V 3nF, which corresponds to approx. 10 meter. Parallel control cables (laid together) at 230V 0.5nF, approx. 2 meters. The maximum parallel capacity of the control cables is 12 to 24V UC 0.03Microfarad, which corresponds to approx. 100 meters. No continuous power supply is required, so no loss in standby mode. As of production week 48/16, the radio telegrams can be encrypted. The internal rotary switch is used to activate or deactivate the alarm Deactivation of encryption required and is in central position in operation. Activate encryption: Turn the rotary switch to the right and press the buttons once. Disable encryption: Turn the rotary knob to the left and press the buttons once.This text is machine translated.
