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.

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:
