EL20
- Infrared outdoor barrier
Overall Characteristics
• 4 barrier 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
• Compensation of expansion caused by heat excursion, thanks to a special
expansion joint.
• 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
• Selectable range according to type of installation (see TX Programming).
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)
• Alarm memory
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
the transmitter and the receiver both be placed in the
same direction (Figure 3)
• Tampering with the product will void the warranty.
• The two columns are supplied in pairs (Tx and Rx).
Always replace the pair, if required for maintenance
purposes.
