SYSTEM DESCRIPTION
The ILIA MODEL ERHS0712 detector consists of a Transmitter Unit, a Receiver
Unit and a Beam Controller Unit for programming, setting and testing. The Beam
Controller Unit is used to remotely manage the detector or detectors in the field
using a single line. The Beam Controller Unit is put at a place on ground level from
where the detector can be controlled without having to climb up to the detector, as
regards all normal operations. The Beam Controller Unit is made of plastic, has a
keyboard for programming and a backlight 16x2 display.
By entering a password of 4 digits you can program the system from ground level to
determine the detector's signal level, to check environmental disturbances, to set
the required thresholds based on these and to check the alarm threshold; the
default password FFFF can be changed by the programmer by following the
instructions in the remote programming menu.
The system configuration menu becomes available when you just touch any of
the 5 buttons on the keyboard and by then entering the default password FFFF on
the first programming session, customising the password from then on (the
password can be reset if lost or forgotten by use of the beam controller Unit reset
hardware).
The Beam Controller Unit electronic base permits direct connection of two detector
units; by means of an expansion circuit (SMLS), it is able to pilot up to 8 detectors
connected together and a connection with two stub lines or by a closed loop. With
this second typology the system continue proper working even if the cables are cut
or in the case of a short circuit by the protection circuit inserted in each single
detector. There are also programmable relay contacts in the Unit for each
individual detector connected. These relays can have their polarity reversed with
the use of the software and permit the transmission to a single central unit of the
individual alarm, fault and maintenance request signals. Any breakdown in
communication between Beam Controller Unit and the detectors connected to it
will be immediately signalled by the simultaneous flashing of the yellow Led and
the green Led on the Transmitter and the Receiver, as well as being indicated on
the display of the Beam Controller Unit itself.
The controller is also available in the Dust version (CSRLS-2-DUST), suited to
very difficult environments, using special VdS certified software that enables the
detection threshold to be calculated up to the maximum limit permitted by standard
EN54-12 without losing the principal characteristics of this model: producing early
detection in any environment.
ILIA with the Dust version controller has already come successfully through lab and
environmental real scale fire testing; these tests have shown that the model's
detection ability assures early alarm in any environment, overcoming unfavourable
conditions that could give rise to false or to fault alarms.
ILIA with the Dust version controller is thus a highly reliable response to the needs
of problematic environments with dust, steam, fumes or particular working
processes where other technologies are unable to assure the required security
and accurate and precise detection.

The working voltage of the equipment is between 12 and 24 Volts without switching
(± 20%). The Transmitter Unit emits a beam of modulated infrared light at 1 KHz in
the form of a cone which crosses the space under surveillance to reach the
Receiver Unit. As the modulated infrared crosses the environment under
surveillance, it collects along its path all information that could suggest the start of a
fire. The events that intervene between Transmitter and Receiver affect the
infrared carrier, alternatively optically modulating it in frequency and in amplitude.
WORKING PRINCIPLE
The Receiver Unit demodulating from the infrared received the information that is
optically gathered, transforms each symptom of a possible fire into corresponding
electrical signals referable to “smoke”.
Such signals are electronically assessed by means of a special algorithm local to
the Receiver Unit, and are transmitted to the Beam Controller Unit. All the units
have a microcontroller that carries out a full scan of the working mode, i.e. not only
of the alarm, but also of faults, blinding and maintenance requests. The messages
are clearly given on the display and repeated by the four leds on the Unit, as well as
with the local led's on every individual piece of equipment. A message on the
display will indicate the type of event and the detector number.
NOTE: The Dip-Switch must always be used during installation to
determine the detector address number, also if is there only
one detector. In the loop configuration the Dip-Switch 4 must
stay in the «OFF» position.
The connection of one or more detectors is with leads of a minimum cross-section,
2
in accordance with current regulations, of 0.5 mm . For the type of cable to use
please refer to current regulations; it is not necessary to use shielded cable.
The detection of the start of a fire will mean information is sent from the field
(detector) to the Beam Controller Unit which will in turn send an alarm signal to a
central control unit. System resetting is possible both from the Beam Controller
with a dedicated command or from the central control unit or closing, by a normally
open contact, the two terminal blocks of the MRS module.
The Beam Controller Unit can be used to set the blinding fault relay switching delay
for every individual detector, for times from 0 to 90 seconds.
The Receiving Unit (RX) has an internal diaphragm that means it is possible,
following the instruction to mechanically set for the use of a diaphragm filter, to
solve environmental problems in particular architectural situation where there are
awkward reflections or the optical beam must work in limited spaces or get dirty
before the starting up.

ASSEMBLY PROCEDURE
NOTE 1: Use the SETRONIC "Allen Key" for the opening and the closing of the detector and the
mechanical alignment of the equipment.
NOTE 2: to grant that the socket maintain the IP65 protection degree, be sure that i twill be fixed in flat
surface. If this it is not possible use a bracket or a swivel.
1. Fix the socket connection of the detector and carry out the wiring of the line (power supply and serial line).
2. Set the address of the detector between 1 and 8 consequently using the Dip-Switch according to the table on page
79. This operation must be done on both unit, so to have the same address on Transmitter and Receiver.
It's suggested to make these operation before the fixing of the socket.
NOTE: The Dip-Switch 4 must be set to ON only in the last socket connected to the line open. It must
also be set with a single detector.
3. Insert the connector plug on the bottom of the detector into the socket until you hear a "click", then lock the unit to
the socket by rotating the hooks with the appropriate Allen key and guide it to the paired device from the opposite.
4. Repeat above operations for all the detectors installed. Verify that the Transmitter and Receiver pair have the
same address.
CONNECTIONS CHECK BEFORE START-UP
(to be made only with the loop configuration)
1. Disconnect the two terminals "power output" and "serial line" of the main module and the two terminals "power
output" and "serial line B" of the expansion module.
2. With a multimeter measure the resistance on the wires, between the positive output of the first power supply and
the positive of the second supply line. Also measure the resistance, always on the wires, between the negative
output of the first power supply and the negative of the second supply line.
3. Both resistance values read, must be less than 100 Ω
4. Reconnect the cables and make sure that the clamps are inserted securely.
CALIBRATION PROCEDURE
1. Power the system via the controller and set the number of detectors connected and the configuration of connection
to serial line. The controller also allows the use of the two serials in an independent manner, as if they were two
separate lines open. In this case, the addresses remain the same from set 1 to 8, but you set the end of the line
(Dip-Switch 4 to ON) of both the last detector.
2. At this point the green led of the two detector units should switch on and you must switch controller, a short flash
confirms the continuous scanning of the line. If on the units is present the condition of led flashing green and yellow
with flashes of about 2 sec., means that there is no serial communication (check the wiring for possible errors or
inversions) or incorrect configuration of the switch address. In such a case please verify: the cabling for possible
mistakes or inversions, the wrong configuration of the address switches (double same number) or the wrong
number of connected detectors (menu system set-up).
3. Point the Transmitter through the Allen key adjustment in order to obtain the led blinking yellow.
4. Starting i.e. from the left to move the unit slowly until the yellow led stops flashing. Then rotate the unit to the right
(the yellow led starts to flash again). Count how many turns of the key are made to obtain the yellow led off to the
opposite side. Reposition the center of movement found by dividing in half the number of revolutions counted. The
yellow led continues to blink.
5. Do the same for the vertical axis.
6. Point the Receiver following the same steps 3, 4, 5.
7. Perform the calibration by the ground controller to follow the menu <Auto Adjust>.
8. Now cover the Transmitter Unit or Receiver Unit with a card or opaque object. When you cover the Unit check that
the yellow led remains continuously on.

4. Reconnect the cables and make sure that the clamps are inserted securely.
CALIBRATION PROCEDURE
1. Power the system via the controller and set the number of detectors connected and the configuration of connection
to serial line. The controller also allows the use of the two serials in an independent manner, as if they were two
separate lines open. In this case, the addresses remain the same from set 1 to 8, but you set the end of the line (Dip-
Switch 4 to ON) of both the last detector.
2. At this point the green led of the two detector units should switch on and you must switch controller, a short flash
confirms the continuous scanning of the line. If on the units is present the condition of led flashing green and yellow
with flashes of about 2 sec., means that there is no serial communication (check the wiring for possible errors or
inversions) or incorrect configuration of the switch address. In such a case please verify: the cabling for possible
mistakes or inversions, the wrong configuration of the address switches (double same number) or the wrong
number of connected detectors (menu system set-up).
3. Point the TRx Unit by Allen key adjustment in order to obtain the led blinking yellow.
4. Starting i.e. from the left to move the unit slowly until the yellow led stops blinking. Then rotate the unit to the right
(the yellow led starts to flash again). Count how many turns of the key are made to obtain the yellow led off to the
opposite side. Reposition the center of movement found by dividing in half the number of revolutions counted. The
yellow led continues to blink.
5. Do the same for the vertical axis.
6. Point the unit of reflection following the same steps 3, 4, 5 and looking LEDs on the TRx Unit.
7. Perform the calibration by the ground controller to follow the menu <Auto Adjust.>.
8. Now cover the Reflection Unit with a card or opaque object. When you cover the Reflection Unit check that the
yellow led on the TRx Unit remains continuously on.
