5. Prism targeting mode
4.2 Prism installation
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.
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.

On ranges of ≥5 metres and ≤50 metres use a MAB50R. On ranges of >50
metres and ≤100 metres use a MAB100R.
5. Prism targeting mode
Apply power to the Detector. There is a 5 seconds pre-charge delay after power is
applied to allow the internal circuits to stabilise correctly.
Do not remove the detector from the wall during this action.
Using the mode switch (See fig. 4) select Prism Targeting Mode (Switch will be in
the up position). At this time there may be a fault condition showing on the panel.
Find the prism by adjusting the horizontal and vertical thumbwheels until the Amber
LED is flashing. Both the Red and Amber LED will be OFF when no signal is being
received. The Red LED will start to flash when a weak signal is received. When a
stronger signal is received, the Red LED will extinguish and the Amber LED
will start to flash.

At this point it is essential to test that the prism and not another surface is
reflecting the beam.
This can easily be confirmed by covering the prism with a non-reflecting surface and
confirm that the AMBER and RED indicators are OFF. Please read this in conjunction
with section 10.
6. Alignment mode
Mechanical alignment is provided by two adjustment thumb wheels on two sides
of the Detector, positioned just behind the Detector Head cover. Adjustment is
achievable in both axes.
