Overall Characteristics
•4barrier models are available: EL20RT/05 (0,5m - 2 beams),
EL20RT/10 (1m - 4 beams), EL20RT/15 (1,5m - 6 beams), EL20RT/
20 (2m - 28beams).
•Extremely compact size allows installation between window and blinds,
or roller shade
•High resistance to shocks and to severe weather conditions, thanks to
the polycarbonate case and the gasket system on closing cover
•Resistance to UV rays
•Compensationofexpansioncausedbyheatexcursion,thankstoaspecial
expansionjoint.
•Maximum stability of columns installed on wall with intermediate fixtures
•Protection against accidental opening and removal
•Easy optical alignment (without calibration tools)
•Microprocessor-controlled SMD technology
•Three (3) selectable operating modes: point-to-point beams, adjacent
beams, crossed beams
•Selectablerange according to typeof installation (seeTXProgramming).
The distances shown are indicative and may change according to where
the barrier is installed.
•Identification code between TX and the corresponding RX
•Optical barrier synchronism (without connection in row)

Installation hints
•Avoid as much as possible the presence of objects that could obstruct
the beam
•Use of a shielded cable is advisable, preferably, one cable for each barrier
•If barriers are installed consecutively or in parallel, use the configuration
described in Figure 1
•Position the barriers so that the sun rays do not hit the receivers directly
(see figure 2).
• Check full operation of the barrier in the case of installation near large
reflecting surfaces which could cause undesired optical coupling.
•To fix columns, use only the screws supplied with the barrier
•The barrier can be installed either with the cable at top or at bottom; the
only precaution to be observed in this case is that
thetransmitter andthereceiverbothbe placedinthe
same direction (Figure 3)
•Tampering with the product will void the warranty.
•Thetwo columns are suppliedin pairs (Tx andRx).
Alwaysreplace the pair,ifrequiredformaintenance
purposes.

Installation
•Arrange the columns (receiver and transmitter) one opposite the
other at the same height (the optical power of the Tx column can
be programmed according to the distance between the two columns
- see TX Programming). Mark the fixing screw holes and drill the
supporting surface; intermediate blocks (supplied on production
models more than half a meter high) are available to improve the
column’s adhesion to the wall: Read the NOTE below if you wish to
use these blocks, otherwise go to the next step.
•Fix the column to wall by inserting the fixing screws inside the
appropriate slotted holes, and tighten them (Figure 6).
•Insert the oval-shaped rubber seal (supplied on production models)
as shown in Figure 4.
•Run the cable through the appropriate slotted holes (Figure 6) if
you wish to use the rear core hitch.
•If necessary, cut the programming jumpers (see par. “TX and RX
Programming”).
•Cutthecolumn-stop posts (ontheRX andTX)beingcarefulto remove
anyresidual traces ofburrstoavoidcompromising theheatexpansion
compensation (Figure 6).
•Close the cover and fasten with appropriate screw (see Figure 5).

NOTE 1: COLUMN WALL FIXING
•Afterhavingmarkedthe positionoffixing screwholes,
drill the holes necessary for the intermediate blocks
(Figure 8).
•Fix the intermediate blocks (with appropriate screws)
making sure that blocking fins can rotate freely (see
Figure 7).
•Fasten the column to the wall using the screws
supplied for this purpose.
•Push the fins of the intermediate blocks with a
screwdriver so that they rotate (Figure 9).

SUMMARY OF RX PROGRAMMING
TC Input
•The TC is a command generated by the anti-tampering unit to inform the barrier of the system’s condition (armed or disarmed).
When present (disarmed system), the TC enables:
- viewing of the alarm memory
- blocking of the alarm relay, for less wear.
•When it is not present (armed system), the TC command allows viewing of alarm events.
•The TC command is considered to be present when the writing –12 V is indicated on the corresponding cable (Brown).
•The TC command is considered to not be present when the writing 0 V is indicated on the corresponding cable (Brown), or when the
cable is not connected.

Factory Parameters
•The RX column is supplied with point
to-point operating mode.
•TheTX column is supplied with integral
jumper: minimum rating.
Fig.10
Fig.12
RX Programming
•Each RX column is supplied with 2 jumpers that are used for
programming the operating mode.
•INTEGRAL JUMPERS: POINT-TO-POINT BEAM MODE
An alarm is generated when a single beam is interrupted for at least
one second, or when 2 adjacent beams are interrupted for >0.1 sec.
•YELLOW CUT JUMPER: ADJACENT BEAM MODE
An alarm is generated when 2 adjacent beams are interrupted for at
least >0.1 sec.
•2 CUT JUMPERS: CROSSED BEAM MODE
An alarm is generated when a single beam is interrupted for at least
one second, or when 2 beams are interrupted for >0.1 sec.
WARNING: The range of crossed beams is typically 0.9 m and can
increase if the columns are installed in the presence of strong
environmental light.
TX Programming
• Each Tx column is supplied with 1 jumper for programming the
transmitted optical power as follows:
- integral jumper: reduced optical power
- cut jumper: maximum optical power
The following ranges are obtained according to the selected optical
power:

CONDITION
WARNING: - Detection faults or anomalies
may occur in the case of installation near
reflecting surfaces due to undesired optical
coupling. In many cases, the problem may
be solved by setting the curtain to reduced
optical power by leaving the Tx jumper intact.
Always check full functionality of the curtain
before completing installation

First powering up
•At first powering up, after the columns have been fixed one in front of the other, the beams are automatically synchronized by
the optical signal.
•The Coding of TX coupling with RX is performed automatically
•The receiver Led indicates any malfunctions:
- Led OFF: relay closed, barriers are functioning correctly
- Quick-flashing Led: see section titled “Troubleshooting”

Trouble
Led is lit with fixed light
and the relay contact is
open.
Led is flashing and the
relay contact is open
Led is always OFF and
the relay contact is open.
Led is lit with fixed light
and the relay contact is
closed
Led is always OFF and
the relay contact is closed.
Possible Cause
• Incomplete acquisition of random code
• Power supply to TX column missing
• Barrier is excessively off-center
• Range selection jumper is not set correctly
• RX column fault
• Power supply to RX column missing
• Alarm memory enabled
• TC present
Corrective Measure
•Check that there are no obstacles
between barriers
•Supply TX column
•Re-position barriers
•Check the distance between barriers and
select the correct range
•Check the RX column and replace, if
necessary
•Supply RX column
•Arm the system and disarm, if necessary
(refer to the TC input)
•Arm the system and check connections
