1. SB-N : Technical Workshop 1

2. General Presentation QUICK and EASY settings Alignment feedback Buzzer and Leds indication One person to set-up the columns The new SB Beams offer a high performance of detection level combined with a simplified installation. High performance of DETECTION Constant detection no matter what the distance No detection gap between cells IDENTICAL columns 1 product reference, no difference between the transmitter and receiver columns Quick installation and maintenance

3. i DIS 100Hz : Every cell/column is identical Patent N° 06 02310 TX RX Tx Rx Tx + Rx Tx + Rx New Fresnel Infrared cells integrating the Tx and Rx functions (DIS) TX + Rx All cells are identical 2 different cells SB SB-N

4. i DIS 100Hz: Alignment Feedback SB -Several walks between columns or with the help of a colleague to align each barrier SB-N -One return trip to align each barrier - easier & faster to align

5. i DIS 100Hz: Contacts available on every column Alarm contacts available on every column Technician can adapt cabling of columns according to the site Technician doesn’t need to worry about installing Tx or Rx columns in a specific place according to a plan.

6. ii Alignment « 80% of the problems linked to infrared barriers are due to incorrect alignment » SB is just as reliable as any other infrared barrier, however the SB is harder to align SB-N is easier to align and optimises the alignment to eradicate problems linked to an incorrect alignment

7. ii Alignment: Integrated Alignment Tools No external alignment tool (eg. Voltammeter) is required. The alignment tools are integrated inside each column. - Buzzer - LEDs - Optical View finder

8. ii Alignment: SB Difficulty to align SB (the longer the range, the harder it is to align) No information concerning the level of received signal on the Tx column Need the Alignment Tool SB51

9. ii Alignment: SB-N SB-N Alignment D.I.S. Technology allows an automatic TX alignment Integrated Alignment Tools – Optical viewfinder – LED indicators – Powerful buzzer 1 person needed for an optimal alignment

10. ii Alignment: Fresnel Lens The Fresnel Lens centralizes the light signal either transmitted or received. This offers a greater tolerance to misalignment and a better signal level in adverse weather conditions (strong wind, fog, snow, etc.)

11. iii When do infrared barriers trigger an alarm? 4 V t 0,8 80% Alarm Threashold = -80% of Reference Level Infrared Signal Alarm Threashold

12. iii Influence of fog and dirt on triggering an alarm (without Automatic Gain Control) V 4 t 0,8 Infrared Signal Alarm Threashold 1 Fog or dirt on the cover Little room to avoid unwanted alarms 20% fall in infrared signal = Alarm

13. iii Influence of columns installed close on triggering an alarm (without Automatic Gain Control) V 4 0,8 Infrared Signal Alarm Threashold Too much room to have an alarm 90% fall in infrared signal = Alarm 6 Columns installed close to each other or indoors

14. iii SB-N: With Automatic Gain Control V 4 t 0,8 Infrared Signal Increase or decrease the Gain to keep reference level 80% fall in infrared signal = Alarm Whatever the weather conditions, SB-N will always have a 80% difference between the reference level and the alarm threshold. This makes the SB-N more reliable than other systems in adverse weather. Reference Level

15. iv Without Multiplexed Beams If the infrared beams are not multiplexed then the detection will be poor as receiver cells will receive infrared light from all transmitter cells. If all the beams are not cut there is a risk that the receiver cell will continue to receive infrared light and so no alarm will be triggered. Tx Rx Intrusion: but Rx cell is still receiving infrared beams from other cells and so there is a risk that no alarm is triggered.

16. iv SB-N: Multiplexed & Synchronised Beams Time With the multiplexed beams of the SB-N, we know exactly which beam(s) is/are cut and so we have an accurate and reliable detection. Because we multiplex, we need to synchronise the beams at the same time. Synchronisation means that the Rx cells “open the door” at the same time that the opposite Tx cells are emitting infrared light. Because we know which beams are cut, we can also have a dual beam detection of parallel beams because we know that the beams that are cut are adjacent.

17. iv SB-N : With Multiplexed & Synchronised Beams What are the advantages of having multiplexed and synchronised beams? The detection is more reliable. Why? i Because the Rx cells only receive an infrared signal from 1 Tx cell so there is no interference from other Tx cells. ii Because it allows us to have a detection between modules and so there are no dead zones between modules, but a wall of infrared that cannot be breached. iii Because it allows us to have a dual parallel beam detection (between cells and between modules) that will greatly reduce the number of unwanted alarms from birds and flying objects.

18. v Channels: SB-N SB-N : Optical synchronisation per cell. Because the modules are multiplexed and synchronised (via the inter-connection cable), there is only one pair of cells emitting and receiving an infrared signal at any time. Thanks to this, we only need to have one channel per barrier. This also means that we avoid any interference between barriers installed in a long line. C1
