Eltako 30000301 F4USM61B 4-way universal radio transmitter module

Wireless 4-way universal transmitter module. With internal antenna. With battery (lifespan 5-8 years). For flush mounting. 45mm long, 45mm wide, 18mm deep. This wireless transmitter module has four channels and can therefore send radio telegrams to the Eltako building radio like a 4-channel wireless button. E1 triggers a radio telegram like pressing the top rocker of a wireless button with a rocker, E2 like pressing the bottom rocker (or the right rocker of a wireless button with a double rocker), E3 like pressing the top left rocker of a wireless button with a double rocker and E4 like pressing the bottom left rocker of a wireless button with a double rocker. The telegram when the control contacts open is identical to releasing the wireless button. The control inputs can be activated with internal jumpers either for buttons (delivery state), window-door contacts or motion detectors. With a cable length of up to 10 meters, conventional buttons, window-door contacts or potential-free motion detector contacts can also be connected to terminals E1, E2, E3 and E4. The opposite pole is the GND terminal in each case. Attention! Do not apply any voltage. The electronics are powered by an internal CR2032 button cell. To activate the battery supply by pulling out an insulating strip and to change the battery, the housing must be opened. This is also necessary to select the modes. To open the housing, use a screwdriver to unlock the cover at the tabs and remove it.
