Wireless outdoor transmitter module 2 channels. LxWxH: 60x46x30mm (dimensions without screw connection). With internal antenna. No standby loss. The wireless transmitter module FASM60-UC has two channels and can therefore send radio telegrams to the Eltako building radio like a wireless button. A1 triggers a radio telegram like pressing the top rocker of a wireless button with a rocker and A3 like pressing the bottom rocker. The telegram when the two control contacts are opened is identical to that of releasing the radio button. Multiple wireless transmitter modules must not be controlled at the same time. There is an M12 screw connection on the underside for the IP54 waterproof connection. Connection to an internal 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 is sent from A3 once a minute as long as the control voltage is present. For example, for central commands with priority. 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 lines (laid separately) is 3nF at 230V, which corresponds to approx. 10 meters. Parallel control lines (laid together) at 230V 0.5nF, approx. 2 meters. The maximum parallel capacitance of the control lines is 0.03µF at 12 to 24V UC, which corresponds to approx. 100 meters. No constant power supply required, therefore no standby loss. The radio telegrams can be encrypted. The internal rotary switch is required to activate or deactivate the encryption and is in the middle position during operation. Activate encryption: Turn the rotary switch to the right and press once. Deactivate encryption: Turn the rotary switch to the left and press once.
