Product and functional description

The IR Receiver Decoder S 450 translates the IR signals it

receives for wireless control from IR hand-held remotes

S 425 or from IR wall switches AP 420, AP 421 and

AP 422 into bus telegrams. IR control signals of a pair of

buttons or switches on an IR hand-held or an IR wall

switch transmitter can be evaluated for the individual

buttons or for the pair of buttons.

When configured for evaluation as individual buttons the

IR control signals for the corresponding individual button

or switch can be translated into bus telegrams for

• Switching (On, Off, Toggle)

• Single-button dimming

• Single-button solar protection control

• Door bell function (Press on/off, Release off/on)

• 1-bit scene control

• 8-bit scene / effect control

• sending 8-Bit value (percent, 0...255)

• sending 16-Bit value (temperature value, brightness,

0...65535)

• forced control switching (on / inactive; off / inactive)

Depending on the selected function, after sending the

corresponding telegram a second telegram may be sent

time-delayed or alternatively, another function may be

sent on a long button press.

This allows for a simple implementation of a stair case

lighting timer. In addition to the primary function of the

upper button “Switching, On” a second telegram with a

time delay of 5 minutes for the function “Switching, Off”

is configured.

When configured for evaluation as a pair of buttons the

IR control signals for the corresponding pair of buttons or

switches can be translated into bus telegrams for

• dual button dimming with stop telegram

• dual button solar protection control

• sending percent value (variable)

• sending 8-Bit value (variable)

• forced control switching (on / off / inactive)

• 1-bit scene control

• 8-bit scene / effect control

Depending on the selected function, after sending the

corresponding telegram a second telegram may be sent

time-delayed.

The operation of each individual button may be inhibited

via a communication object.

With the ETS the specific parameters and addresses are

assigned appropriately, and downloaded to the IR receiv-

er decoder S 450.

A magnet is used for contactless toggling between nor-

mal operating mode and addressing mode for transfer-

ring the physical address. A programming LED behind the

black IR receiver lens displays the normal/addressing

mode.
