Connecting IR radiators

Connect the infra-red radiators to sockets . The SI 29-5 will modulate the
infra-red light which will then be radiated by the IR radiators.

You can connect a maximum of 50 radiators to the SI 29-5 modulator. You
can also use different radiators (mixed operation):

• SZI 20 Low power infra-red radiator for small rooms, cascadable

• SZI 1029 High power infra-red radiator, IR radiating power 5 W,
socket for connection of additional SZI 1029, SZI 1029-10
or SZI 20. Black or unpainted aluminium housing.

• SZI 1029-10 High power infra-red radiator, IR radiating power 10 W,
socket for connection of additional SZI 1029, SZI 1029-10
or SZI 20. Black housing.

씰 N.B. Please also read the instructions for the IR radiators!

Avoid very long cable lengths because they lead to signal cancellation when
IR radiators are facing one another:
