ENCODING PHOTOCELLS “ IR/IT 2241
GB
Wall-mounted encoding photocells, 180° rotation and range of up to 20 mt.
The code for the transmitted signal, which must be set at the time of installation, minimises the possibility of interference
between devices.

IT 2241 D
Selecting the Operating Range ( SW1 Dip Switch No. 1 ) :
The maximum distance of operation of the battery-operated photocell is approximately 10 metres at normal power ( Dip
Switch No. 1 OFF “factory configuration” ) and approximately 20 metres at maximum power ( Dip Switch No. 1 ON ).
Selecting Operating Code “ A ” and “ B “ ( SW1 Dip Switch No. 2 ) :
The photocell has two operating encoding channels "A" and "B", in this way it is possible to install 2 pairs of the same model
without any interference between them. Code "A" ( Dip Switch No. 2 OFF “factory configuration” ) and code “B” ( Dip Switch
No. 2 ON ), must be accordingly selected in the same way, at the time of installation, on both the transmitting part ( IT 2241 )
and the receiving part ( IR 2241 ).
Connections:
1 – 12/24 Vac-dc
2 – 0V

ENCODING PHOTOCELLS “ IR/IT 2241 BATTERY “
GB
Wall-mounted encoding photocells with the battery-operated Transmitter function, with 180° rotation an d range of up to 16
mt.
The battery-operated photocell IR/IT 2241 solves problems related to setting up electrical cables to connect the transmitter
The code for the transmitted signal, which must be set at the time of installation, minimises the possibility of interference
between devices.

IT 2241 B
Power supply and autonomy:
The transmitter is powered by a 1.5 Volt Alkaline battery. The average battery life is approximately 18 months at normal power
and approximately 12 months at maximum power. The battery life depends on the quality of the batteries being used.
Selecting the Operating Range ( SW1 Dip Switch No. 1 ) :
The maximum distance of operation of the battery-operated photocell is approximately 8 metres at normal power ( Dip Switch
No. 1 OFF “factory configuration” ) and approximately 16 metres at maximum power ( Dip Switch No. 1 ON ).
Selecting Operating Code “ A ” and “ B “ ( SW1 Dip Switch No. 2 ) :
The photocell has two operating encoding channels "A" and "B", in this way it is possible to install 2 pairs of the same model
without any interference between them. Code "A" ( Dip Switch No. 2 OFF “factory configuration” ) or code “B” ( Dip Switch No.
2 ON ), must be accordingly selected in the same way, at the time of installation, on both the transmitting part ( IT 2241 ) and
the receiving part ( IR 2241 ).
Important:
It is possible to connect an "NC" safety device to the transmitter (for example a safety edge mounted on the mobile edge of a
sliding gate): when the contact opens the transmitter stops transmitting.
If no "NC" safety device is used, inputs 3 and 4 must always be jumpered.
Connections:
1 - Do not use
2 - Do not use
3 - "NC" safety device (Jumper only if not used)
4 - "NC" safety device (Jumper only if not used)
Attention
−−−− The alkaline battery 1.5V (AA) must be replaced every year to guarantee optimal functioning.
−−−− To replace the discharged battery remove the plastic lid, extract the battery in use and insert a new one, respecting the
polarity indicated on the battery compartment.
−−−− The used batteries must be disposed of in the appropriate gatherers.
