Eltako FSM61-UC Funksendemodul

The wireless 2-gang transmitter module with internal antenna has no standby loss and is suitable for flush mounting. It measures 45 mm in length, 45 mm in width and 18 mm in depth. The FSM61-UC radio transmitter module has two channels and can transmit radio telegrams in Eltako building radio like a radio push-button. A1 triggers a radio telegram like pressing a rocker switch at the top, while A3 simulates pressing a rocker switch at the bottom. The telegram when the two control contacts are opened is identical to that of a radio button when it is released. Several radio transmitter modules must not be controlled at the same time. The universal control voltage at +On/-A2 processes control commands from 8 to 253 V AC or 10 to 230 V DC with a minimum length of 0.2 seconds. The maximum parallel capacitance of the control lines at 230 V is 5 nF, which corresponds to a length of approx. 20 metres. 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, e.g. for centralised commands with priority. A constant power supply is not required, so there is no standby loss. The rotary switch is required to activate or deactivate the encryption and is set to AUTO during operation. To activate the encryption, turn the rotary switch to the right stop (key position) and press once. To deactivate encryption, turn the rotary switch to the left stop (crossed-out key position) and press once.
