S1, S2 Transmitters
E1, E2, E3 Receivers
R1, R2 RF repeaters
− S1 sends telegram A directly to E1 with no repetition
− S2 sends telegram B directly to E1 and E2; however, E3 is too far away from S2 and
can only be reached via repeater R1
− R1 repeats signal B from S2 and reaches devices E3 and E1 through B’; hence, E1
receives signal B from S2 directly and via R1
− R2 receives the repeated signal B’; rerepetition by R2 is not possible
The only type of RF repeater suited for use on Synco living plants is the ERF910.
GAMMA wave RF repeater type UP 141 is not compatible with the Synco living system.
The Synco living system and the ERF910 repeater support the repetition of GAMMA
wave radio telegrams.
• GAMMA wave actuators matched to the QAX910 central apartment unit can be
directly assigned to an RF repeater
• Other GAMMA wave devices that do not directly communicate with the central
apartment unit and – for this reason – have not been matched to it, can subsequently
be acquired on the central apartment unit and assigned to an RF repeater
The Synco living system does not support the repetition of Hager tebis radio
telegrams. If there are range problems in connection with Hager tebis TX devices, a
Hager RF repeater will be required.
