    0.7dB/Hour are corrected automatically. 3. Detector Positioning. It is important that the MAB50R / MAB100R detectors are positioned correctly to minimise the detection time. Experiments have shown that smoke from a fire does not rise directly upwards, but fans out or mushrooms due to air currents and heat layering effects.

    www.acornfiresecurity.com Typical Minimum Beam Spacing Beam Distance Beam Spacing Beam Distance Beam Spacing 0.87m 5.25m 1.75m 6.12m 2.62m 7.00m 3.50m 7.87m 4.37m 8.75m In all installations the latest national fire standards must be consulted. If there is any doubt on the correct mounting height, positioning may be determined by smoke tests.

    Due to the principle of the detector i.e. reflective, the prism must NOT be mounted on glass or a polished reflective surface. Mount the Prism on a solid structure, 90º to the beam path, between 5 to 50 metres (MAB50R), and 50 to100 metres (MAB50R) directly opposite the Detector.

  • Page 6: Prism Targeting

    Ensure that there is a clear line of sight to the Detector, taking care that no moving objects i.e. doors, mechanical lifting equipment etc, will interfere with the beam path between the Detector and Prism. Note: On ranges of ≥5 metres and ≤50 metres use a MAB50R. On ranges of >50 metres and ≤100 metres use a MAB100R.

Using the mode switch (See fig. 4) select Run Mode (Switch will be in the down position). On exiting alignment mode the Detector will perform an internal calibration check. If this fails, which would be due to bad alignment or either electrical or optical noise, the power level will try to compensate.
