SOMup4 S2: The radio receiver for greater range

The radio receiver for greater range

The bidirectional 4-channel radio receiver module SOMup4 S2 replaces the SOMup4. The option of connecting an external antenna allows you to increase the range significantly with the receiver installed in a metal post or in shielding housing - in particular in combination with the SOMloq2 hop function.

With the SOMup4 S2, due to the optional connection of an external antenna, operators and control units still working with the # 7000VXXX radio receiver can be converted to the SOMloq2 radio system.

All operator sets have been converted to the new SOMup4 S2. The already existing antenna for 868.8 MHz (Item Number 7004VXXX) can be used. In order to use the external antenna, the jumper must be removed or moved and the antenna plugged in as indicated by the symbols on the housing:
