DIGITAL RADIO CONTROLS WITH PROGRAMMABLE CODES S438 AT 433 MHz 'FM'
Description
The S438 radio control system consists of one or more transmitters and one or
more receivers which can be combined to meet the specific needs of the system.
The code setting method, using a 14-way dip-switch, allows up to 16348 user code
combinations and the type of transmission protocol (not static but cyclic) makes
the system easy to install and secure.
Thanks to the FM/FSK modulation the system gives greater performance when
faced with disturbance and noise with respect to a traditional system using AM/
ASK modulation.
Use
The S438 radio control allows the remote activation of electrical and electronic appli-
ances with its best use in the following areas: automatic opening systems, alarm
systems, and in all systems which require remote control activation (without wires),
in compliance with the safety standards governing the installation of appliances.
Transmitter versions
TRQ438200 Miniaturised transmitters
TRQ438400 Miniaturised transmitters
Receiver versions
RMS438200 Mini box receiver for indoor use
RSS438200 Slot-in receiver card
Slot-in receiver cards (fig. 5)
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 CS1031) is inserted directly into an appliance
which is designed to receive and has the following electrical connections:
12V ac-dc with jumper "J1" in position "B"
24V ac-dc with jumper "J1" in position "A"
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 activated by selecting the functions A-B-C-D and
made to correspond with the transmitter channels CHA-CHB-CHC-CHD by setting
the jumpers situated on the circuit board (fig.3,4).
Mini receivers IP20 (fig .6)
• The mini receiver (printed circuit CS1031) is housed in an indoor container, it is fitted
with an 8-way terminal board and has the following electrical connections:
12V ac-dc between binding posts 7-8.
24V ac-dc between binding posts 6-8.
The mini receivers 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 activated by selecting the functions A-B-C-D and
made to correspond with the transmitter channels CHA-CHB-CHC-CHD by setting
the jumpers situated on the circuit board (fig.3,4).
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 installation sites for the receiver and the antenna should be
carefully chosen.
You are not advised to install 2 receivers at a distance of less than 1,5 m from each
other and it is also 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 correct performance of
the receiver).

SERIAL NUMBER
ZVL282.02
The S438 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
Antenna
The installation of the antenna is fundamental, connected to the receiver it represents
the reception point for the radio control. When installing the antenna the following
points should be observed.
The receiver is supplied with its own antenna which consists of a piece of rigid
wire 170 mm in length.
In alternative it is possible to connect an ANS400 tuned antenna using a coaxial
cable RG58 (impedance 50Ω) with a maximum length of 15m.
The antenna should be positioned out of doors in the highest possible point, visible
and away from metal structures.
Setting the user code and selecting functions
The code is set by means of the 14-way dip-switch and must be the same in both
the transmitter and the receiver. You are advised to avoid setting obvious combina-
tions such as all the dips in "OFF" or all the dips in "ON".
Programming can be carried out after installation whenever required thus allowing
you to constantly maintain a secret user code.
Transmitters
In the transmitters each button corresponds to a different function with the sole
exception of the two button transmitter where the left hand button is associated
with the function CHA and the right hand button can be associated with a different
function by setting the 2-way dip (see fig. 3,4).
