DIGITAL RADIO CONTROLS WITH ROLLING CODES S437
Description
The S437 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 S437 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. During the transfer
stage the codes are memorised in a non volatile memory module. As this is a system based on
dynamic codes each code is processed individually by the receiver.
Important
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 S437 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.

Memory module
This is extractable, furnished with a non volatile EEPROM type memory and contains the transmit-
ter codes and allows you to memorise up to 300 codes (300 channel buttons). The programmed
codes are maintained in this module even in the absence of power.
Receiver antenna installation
Minimum and maximum range of the radio controls. 'Range' is intended to mean the working
distance, measured in free space, between the receiver and the transmitter with the antenna
installed. The range is therefore closely linked to the technical characteristics of the system
(power and sensibility) and varies according to the characteristics of the site in which the system
is located. It therefore follows that to obtain the best results from the radio control the receiver
and antenna installation sites should be carefully chosen. It is not possible to install 2 receivers
at a distance of less than 1.5 m. from each other. It is good practise to position the receiver away
from computer systems, alarm systems and other possible sources of disturbance.
(A bad choice of positioning could compromise the performance of the receiver).
Antenna
The installation of the antenna is fundamental, connected to the receiver it represents the recep-
tion point for the radio control.
When installing the antenna the following points should be observed:
- Both the receivers (Slot-in and Mini) are supplied with their own antenna which consists of a
piece of rigid wire 170 mm in length.
As an alternative it is possible to connect a tuned antenna using a coaxial cable RG58 (imped-
ance 50Ω) with a maximum length of 15 m. The antenna should be positioned out of doors in the
highest possible point, visible and away from metal structures.
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 mechanism which cuts in after at least 25 seconds
of continuous use (this limits battery consumption).
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.
Slot-in receiver cards
(fig. 6)
Warning! The receiver cards must be sufficiently insulated from the parts of the host device
which are powered by the mains.
- The receiver card (printed circuit CS1134) is inserted directly into an appliance which is designed
to receive and has the following electrical connections:
24Vac/dc between the contacts 3-4
The receiver cards are fitted with two relays the outputs of which are marked CH1 (normally open
contact) and CH2 (normally open/normally closed contact). The relays CH1 and CH2 can be acti-
vated by selecting the functions A-B-C-D and made to correspond with the transmitter channels
CHA-CHB-CHC-CHD by setting the jumpers "J1" situated on the circuit board (see fig. 6).
Mini receivers
(fig. 7)
- The mini receiver (printed circuit CS1134) is housed in an indoor container and is fitted with a
terminal board with the following electrical connections:
12Vac/dc between the contacts 7-8.
24Vac/dc between the contacts 6-8 .
The receiver cards are fitted with two relays the outputs of which are marked CH1 (normally open
contact) and CH2 (normally open/normally closed contact). The relays CH1 and CH2 can be acti-
vated by selecting the functions A-B-C-D and made to correspond with the transmitter channels
CHA-CHB-CHC-CHD by setting the jumpers "J1" situated on the circuit board (see fig. 7).

The S437 series conforms to the essential requirements of the directive 99/05/
CE and the technical reference standards have been applied.
Frequency validity: 433.92 MHz for all
Functions
A. Memorising a channel
B. Cancelling a channel (via an associated transmitter)
C. Cancelling the entire user memory
D. Memorising ulterior channels via radio (without having to open the box in which the receiver
is housed)
Attention! Before memorising the transmitters for the first time remember to cancel the entire
memory content.
A- Memorising a channel (fig. 5a)
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 memorised
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 transmitter, 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.
• It is not possible to memorise a user code that is already in memory: In this case when the transmitter
is activated (point 2) the led will stop flashing. The program will only work again when button "P1"
MEMO has been released.
• If the transmitter 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 acti-
vated.
B- Cancelling a channel (fig. 5a)
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 flashing. 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 (fig. 5a)
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: It is only possible to switch from memorising mode to cancelling mode if you haven't already
entered the second part of the memorising procedure (point 4 onwards). Once this part of the proce-
dure has been reached the entire procedure will have to be completed. 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.
D- Memorising a channel (fig. 5b)
Memorisation can be activated by radio (without opening the receiver container) if jumper "J3" has
been inserted (fig. 6,7).
1. Make sure that the jumper "J3" has been inserted in receiver.
2. Using a transmitter, in which at least one channel button "A,B,C or D" has already been memorised
in the receiver, press the button "MR" as shown in figure "5b".
Note: all the receivers within range when the channel button is pressed (and which have at least one
of the transmitter channel buttons memorised) will activate their signal buzzer "B1" (fig. 6,7).
3. Press one of the channel buttons on the transmitter. The receivers which do not contain that channel
code will sound a five-second long "beep" and will then disactivate. The receivers which contain the
channel code will sound a one-second long "beep" and will enter the programming mode.
4. Press one of the channel buttons on the transmitter which you wish to memorise; the receiver will
sound 2 "beeps" of half a second each after which the receiver will be ready to receive another
code.
5. To leave the programming mode wait for 5 seconds without pressing any buttons. The receiver will
sound a five-second long "beep" and will then exit the programming mode.
When the memory is entirely occupied the buzzer will sound 10 rapid "beeps" and will automatically
leave the "programming via radio" mode. Led "L1" will remain lit on the receiver. The same signal
is given each time you try to enter "programming via radio" when the memory is full.
