2.3 Site Preparation
The Murena detector is a detector that, thanks to it operating mode (Doppler effect), does
nor require any specific preparation of the area to be protected. On the contrary, it lends to
being used in those situations where other types of detector will face serious, if not
insurmountable, difficulties.
Therefore, Murena can be used to effectively cover dead zones in barrier systems, where
there is insufficient space to implement cross-overs or overlaps. Another important
application is in the protection of building fascias, balconies and terraces. Ensure that the
wall or ceiling bracket is well fixed, that the Murena is not exposed to the rain (or use the
optional rain shield and back cover accessories), that it is not looking directly at fluorescent
lights and that it is not positioned in front of fans or vents (especially metal) with movable
vanes that can generate unwanted signals.
Murena can work in conjunction with all CIAS bi-static detectors (Minermo, Ermusa, Ermo
barriers) without any particular precautions, without affecting the operation of the Murena or
the barrier, whether the Murena is positioned close to either the receiver or transmitter.
2.4 Dimensions and shape of the detection field
The size of the detection field is asymmetric with a horizontal detection lobe of
approximately 90° and a vertical lobe of approximately 40°. The lobes are shown in figure 2.
