Thomson amplifier relay

(This text is machine translated) The Thomson repeater for radio transmission is an indispensable accessory for your Thombox on large properties or multiple radio barriers such as very thick stone walls. With the relay, the transmission distance between the Thombox and the other wireless accessories can be doubled. Thanks to a permanently installed battery, the relay continues to function for one hour in the event of a power failure. After the amplifier has been connected to the mains via the mains adapter, it does not require any further settings and is immediately functional. Only one relay can be used per Thombox system.
