Photoelectric beams – practical issues
• Site Planning• Foundation for mounting posts• Cabling• Heaters• Power Supply• Precise Alignment• Regular Maintenance
Site Planning
Photoelectric beams – practical issues
Site Planning– Intrusion risks assesement & customer expectation evaluation
– Site evaluation for limits of use of technology
– Enviromanetal conditions evaluation
– Detector position planning
– Product selection
– Channels allocation
Photoelectric beams – practical issues
Mounting posts foundations– Mounting post should be solid & riggid
– Detector can not move
– Pole should be metal
– Foundations should be deep enough
Photoelectric beams – practical issues
Cabling– Apropriate gauge and type
– Laid down in classsified conduit or
– Use dedicated burried cable type
– Preserve core redundancy
– Varistors are optional
– Secure cabling and juntion boxes
Photoelectric beams – practical issues
Heaters
Do not depend on temperature range!
Use of heaters define two phonomena:• Water condensation• Frost
Photoelectric beams – practical issues
Power supply• Detectors 24V DC ~40-60mA (normal operation)
• Heaters 24V AC/DC 400mA• Battery back-up power supply according to EN50131
Photoelectric beams – practical issues
Precise alignment
Photoelectric beams – practical issues
Photoelectric barier sensitivity = Beam interruption time

Regular maintenance(EN50131 grade 2 min.1Y)
Maintenance requirements of Photoelectric beams:- Open the housing- Confirm power supply level Tx/Rx- Check & confirm all connections- Mounting conditon: fastening of detector, post or foundation for rigid and
solid support- Clean with soft damp cloth front cover and beam sheads form dirt and dust- Confirm the beam path for any obstacles in TX/RX line of sight- Confirm alignment level each of the beam separately- Maintain 3 point walk-test

Outdoor PIR detectors – practical issues
• Site planning• Quality of installation• Sensitivity settings• Regular maintenance
– Site planning
– Intrusion risk assessment & customer expectations evaluation
– Siteevaluation for limits of use of technology
– Enviromental conditions evaluation
– Detector position planning
– Product selction
Outdoor PIR detectors – practical issues
Installation point– Stable, riggid detectot mounting
– Detector self-protection
– Installtion instructions (height, etc)
– Orientation towards sun & other potential FA sources
– Limited detector FOV
Outdoor PIR detectors – practical issues
Precise positioning & limit detector range to desired area
– Most important factor for installation quality
– Select operation area & limit detector FoV to defined zone
– Detection area ALWAYS confirm by a Walk-Test
Improper Detection Area = Most Frequent reason of FA!

Detector sensitivity settings– Should correspond to local enviroment conditions
– Should correspond to specific site conditions
– Requires longer testing in variety of circumstances
– Recommended to start form factory defaults
– Detection quality shoudl ALWAYS be confirmed by Walk-Test
Outdoor PIR detectors – practical issues
Commisioning documentation– Site plan with detectors locations & each FoV
– Type and models of used detectors
– Installation height & method
– Power supply voltage
– Detectro function settings
– Serial/Lot number
– Pictures – site, detector, settings, FoV
Outdoor PIR detectors – practical issues
Regular maintenance(EN50131 grade 2 min.1Y)
Maintenance requirements for outdoor PIR:- Open the housing- Confirm power supply voltage- Confrim all connections- Confirm mounting condition: rigid, solid mounting, stable surface- Clean the lens with damp, soft cloth or pressured air.- Clean iside detectro with pressurised air- Confirm cable inlets etc., for water and insects ingress protection- Confirm detector FoV for potential obstacles and FA factors.- Confirm detector operation by Walk-Test
