Page 9: Setting The Address
www.acornfiresecurity.com Setting the address The address of the beam detector is set using the DIL switch. The f rst seven segments of the switch are set to ‘0’ or ‘1’ using a s mall screwdriver or similar tool. The eighth segment is not used. A complete list of address settings is shown be- low. -
Page 10: Fitting The Ref Ective Beam Detector
www.acornfiresecurity.com Fitting the ref ective beam detector Remove the detector housing before installation to prevent it becoming dislodged during the in- stallation process. Position the beam and ref ectors on solid struc- tures at between 0.3 and 0.6 metres below ceiling level. -
Page 11: Targeting, Aligning And Commissioning The Reflective Beam Detector
www.acornfiresecurity.com TARGETING, ALIGNING AND COMMISSIONING THE REFLECTIVE BEAM DETECTOR What is ‘targeting’ and ‘aligning’? The ref ective beam detector will work only if the beam of light hits the ref ector and returns to the receiver. The best possible result is achieved if the centre of the beam hits the centre of the ref ector. -
Page 12: Targeting Explained
www.acornfiresecurity.com Targeting explained When the beam detector is set to ‘targeting’ it is automatically switched to full power. The purpose of targeting is to adjust the detector by panning and tilting until the beam shines on the ref ector which then ref ects it back. Progress in targeting is indicated by two LEDs: Fig 9b no LED illuminated if beam hits outer part of... -
Page 13: Targeting Step By Step
www.acornfiresecurity.com Targeting step by step 1. Switch on the beam detector. Push the mode switch (Fig 12) up to ‘prism targeting mode’. 2. Pan and tilt the beam detector, by turning the thumbwheels, until the centre of the beam hits the part of the ref ector shown in Fig 10b, causing the red LED to f ash. -
Page 14: Alignment Explained
www.acornfiresecurity.com Alignment explained Alignment can only be carried out after successful targeting. When the detector is switched to ‘alignment’ the power of the beam is adjusted automatically. The effect of panning or tilting is still indicated by the LEDs but what they are indicating is different from when the detector is switched to ‘targeting’. - Page 15 www.acornfiresecurity.com 2. The purpose of the second stage of alignment is to manually adjust the detector so as to align the centre of the beam as closely as possible with the centre of the ref ector.

www.acornfiresecurity.com Alarm test A test f lter with a gradient from 0% to 100% black is supplied to carry out functional tests of the re- f ective beam detector. Select the obscuration mark on the test f lter (Fig 24) that corresponds to the obscuration set as described in page 7. -
Page 19: Protocol Data And Fault Indication
www.acornfiresecurity.com PROTOCOL DATA AND FAULT INDICATION Input/Output bits The ref ective beam detector responds to output bits from the protocol as follows: When output bit 2 is set to logic 1 on two or more consecutive pollings the red alarm LED is illuminated. -
Page 20: Troubleshooting
www.acornfiresecurity.com TROUBLESHOOTING Before investigating individual beam detectors for faults, it is very important to check that the system wiring is fault free. Many fault conditions are the result of simple wiring errors. Earth faults on a data loop or any ancillary zone wiring may cause communication errors. -
