DIGITAL RADIO CONTROL WITH PROGRAMMABLE CODE S476
Description
The S476 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 client.
The various receiver models offer the following possibilities: up to 4 channels
and a number of possible combinations equal to 19683, (these are program-
mable through the use of a block of 9 three-way dip-switches).
Use
The S476 radio control allows the remote activation of electrical and elec-
tronic 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.

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.
It is not possible to install 2 receivers at a distance of less than 1,5m 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 reception point for the radio control.
When installing the antenna the following points should be observed:
- only use a tuned antenna ANS400 connected to the receiver 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.
Note: If for some particular reason it is not possible to fit an antenna, a
reasonable performance can be obtained by connecting a 170mm piece of
single pole conductor wire (Ø1mm) to the receiver.
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.
Outdoor receivers IP55 (fig. 1)
The receiver could be:
- in a case fitted with a 12-way terminal board (printed circuit CS927 - fig.1)
with the following electrical connections:
12V ac/dc between binding posts 11-12
24V ac/dc between binding posts 10-12.
The case type receiver is fitted using "fast-fitting" brackets. The bracket
should be fixed to the wall using two raw plugs (check that it is in square).
After connecting the wiring the case should be slid onto the bracket therefore
fixing it to the wall.
If any repair work is necessary the case can be easily extracted by pushing
upwards the action of which will separate it from the bracket.
Interchangeable channel modules
In the receivers the channel functions are printed on the circuit board. The
interchangeable channel modules can only have the following configurations
and must not be mixed:
- from 1 to 4 impulsive relay strips MCC4491R0
- one memory relay strip MCC0381M0
- one timer relay strip MCC0381T0

Slot-in receiver cards (fig.2)
Warning! The receiver cards must be sufficiently insulated from the parts of
the host device which are powered by the mains.
- The receiver card (CS937) 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 (see fig.5,6).
Mini receivers IP20 (fig.3)
- The mini receiver (CS936) is housed in an indoor container, it is fitted with
an 10-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 and CH2 (normally open contacts).
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 (see fig.3).
PROGRAMMING THE TRANSMITTER USER CODE
The transmitters and receivers are supplied with a block of 3-way dip-switches
with which to program the digital codes for each system. Programming can
be carried out more than once, even after the installation, thus ensuring the
total secrecy of the user code. To ensure an exact match between the trans-
mitter and receiver codes when programming the 2 and 4 key transmitters
coupled with receivers with up to 4 channels remember to set the same code
in both the receiver and the transmitter using all the 9 available DIPS (19683
possible combinations). It is important to remember that the receivers can
only respond to one signal at a time.
IT FOLLOWS THEREFORE THAT MULTIPLE FUNCTIONS CANNOT BE USED
CONTEMPORANEOUSLY.
TRANSMITTERS (fig.5,6)
In the transmitters each key corresponds to a different channel, with the
sole exception of the two key transmitters where it is possible to have the
same channel for both keys. (single-channel operation). For double-channel
operation which can be obtained using the second key, set the two-way DIP
switch, located separately from the nine-way user code DIP switch on the
printed circuit board. Once the transmitter's functions have been programmed
or recognized, make sure that every STRIP in the outdoor receiver (which
carries the relay) corresponds to the desired function.
