DIGITAL RADIO CONTROLS WITH ROLLING CODES S449
Description
The S449 Radio control system in "FM" consists of one or more transmitters and one or more
receivers which can be combined to meet the specific needs of the system.
The S449 system uses a highly reliable encoding system guaranteed by the use of dynamic
codes. The code is changed for each encoding transmission through the use of an encoding
algorithm which only the receiver is able to recognise and therefore decide whether or not the
code transmitted corresponds to the original code. The generated code is memorised in the
receiver via radio. The receiver is able to memorise up to 300 different codes that are transferred
into a non volatile memory module
The transmitted code changes for each command (rolling code). If disturbance interrupts the
transmission, the receiver will wait for a different code, the relay can then only be activated by
first releasing and then pressing the transmitter channel button again.
Use
The S449 radio control allows the remote activation of electrical and electronic appliances
with its best use in the following areas: automatic opening systems, alarm systems, and in all
systems which require remote control activation (without wires) using secret codes.

Antenna
To obtain the best results from the radio control device the installation of the antenna is funda-
mental as once connected to the receiver it represents the reception point for the transmitter. A
tuned antenna using a coaxial cable RG58 (impedance 50Ω) with a maximum length of 15m.
must be installed. The antenna should be positioned out of doors in the highest possible point,
visible and away from metal structures. The receiver should be positioned away from computer
systems, alarm systems and other possible sources of disturbance.
Transmitters
The transmitter is pre-coded and is fitted with an integrated circuit which is programmed in
the factory with a unique identification number. All the code parameters are contained in this
integrated circuit (external memory modules are not required) thus making code management
more reliable and the system more secure. The transmitter has an automatic shut down mecha-
nism which cuts in after 25 seconds of continuous use (this limits battery consumption).
• This time can vary from transmitter to transmitter.
Receivers
Warning! The receivers must only be powered by a safety power pack. The use of non
safety power packs could provoke damage to the system.

Jumper "J2" in position Pos A: "impulsive" relay.
The relay remains active while the channel button is kept pressed
down and deactivates when it is released.
Jumper "J2" in position Pos B: "ON-OFF" relay (bistable). The relay is activated
the first time the button is pressed and deactivated when the same button is
pressed again.
Electrical connection receiver RQM44920S (see fig. 2)
- The receiver (CS1159) is housed in an indoor container and is fitted with a 10-way
terminal board with the following electrical connections:
12V ac/dc between binding posts 7-8 with jumper
24V ac/dc
between binding posts 7-8 with jumper
Programmable relay receiver RQM44920S (see fig. 2)
The receiver has 2 relays with outputs between binding posts
1-2-3 (CH2), 4-5-6 (CH1) and contacts C-NO-NC

Channel selection (Jumper "J4"-"J5" only RQM44920S )
The relays CH1 and CH2 can be activated by inserting the jumpers "J4" and "J5" which
can be found on the circuit. The transmitter functions CHA, CHB, CHC, CHD can be
associated with the channels CH1 and CH2 on the receivers as follows:
OUT CH1 (Rx) = CHA (Tx)
OUT CH1 (Rx) = CHB (Tx)
OUT CH2 (Rx) = CHB (Tx)
OUT CH2 (Rx) = CHD (Tx)

Functions
A. Memorising a channel
B. Cancelling a channel (via an associated radio control)
C. Cancelling the entire user memory
Attention! Before memorising the transmitters for the first time remember to cancel the
entire memory content.
A- Memorising a channel
(fig. 1,2)
1. Keep button "P1" MEMO pressed down and the led "L1" will
start to flash slowly.
2. Press the channel on the transmitter which is to be memo-
rised.
3. Keep button "P1" MEMO pressed down until led "L1" starts
to flash again.
4. Release the button and the LED continues to flash
5. Press the channel on the transmitter which is to be memorised again (same transmit-
ter, same channel. If the channel or the transmitter is different you will not be able to
memorise the channel.
6. End of the memory procedure. LED "L1" will remain lit for 2 seconds meaning that the
channel has been correctly memorised.

work again when button "P1" MEMO has been released.
• If the radio control is not activated a second time within fifteen seconds the program

will automatically leave the memory mode without memorising a new user code.
• If a new user code is activated the first time and a different channel (with an already
memorised user code) is activated the second time, the program will automatically leave
the memory mode (because the two codes do not correspond) and the channel present
in the second transmission will be activated.
B- Cancelling a channel
(fig. 1,2)
1. Keep button "P2" DELETE pressed down and the led "L1" will start to flash rapidly
2. Press the channel on the transmitter which is to be cancelled
3. Led "L1" will remain lit for 2 seconds meaning that the channel has been cancelled.
Note: If the user which is to be cancelled is not found in the memory, the led will stop flash-
ing. The program will only work again when button "P2" has been released. If the button is
released before a channel is activated the program will automatically leave the memorising
or cancelling mode.
C- Cancelling the entire user memory
1. Keep buttons (P1+P2) pressed down simultaneously for more than 4 seconds
2. Led "L1" will remain lit for the period of time required for the program to cancel all the
codes (about 8 seconds)
3. Led "L1" will turn off meaning that the cancellation procedure has been carried out.
Note: Once procedure point 4 has been reached the entire procedure will have to be com-
pleted. If you do not wish to memorise a code which you have already transmitted wait for 15
seconds, the led will switch off and the code won't be memorised.
When the receiver's memory is almost full the user search function can take up to 1 second
to complete.
