DESCRIPTION
The Iris EF radiator belongs to the latest generation of infrared
system high power radiators for the wireless Iris audio system.
An electrical signal supplied from the Iris TS infrared control unit is
converted into infrared light invisible to people and radiated into
the room. The signal to be transmitted can comprise up to 16
channels in the range of 2 to 6 MHz (band IV). For installation a
separate mounting bracket is available. Up to 30 Iris EF radiators
can be connected to a total of four signal outputs of one Iris TS
control unit in a daisy chain. If the Iris EF radiator does not receive
a signal, it automatically turns into the standby mode. When the
temperature of the radiator is too high, the system will auto-
matically switch from full power to half power. If the temperature
is still too high, the radiator will be switched to stand-by mode.
