IMPORTANT
:
Ensure the detector is mounted upright on
a vertical surface. If mounting the detector
on a conductive or uneven surface it is
advisable to use the mounting spacer
provided.
This will ensure that the aerial is above the
4mm clearance distance required from the
surface to optimise the transmission range.
MIMIMUM DISTANCE 4MM
ALIGNMENT
Passive infra red movement sensors detect the
temperature changes of moving objects.
Movement across the beams produces the best
response and range whilst movement towards
the detector would be less responsive. Use the
pan and tilt facility to accurately target the
detection zone, and adjust the range of the
detector to cover the required area.
The clear mask supplied with the detector can
be cut and applied vertically or horizontally to
eliminate coverage of a single beam, an entire
long range section or corridor beam for CCTV
applications. When mounting higher than
boundary fences mask off any side beams that
fall outside of the required detection area. Also
ensuring that no obstacles, such as walls or
large trees for example, obstruct the beam
pattern view.
As the unit detects a change in heat in its field
of view, therefore to avoid any false alarms,
direct sunshine, trees, shrubs, ponds, central
heating boiler flues and animals should all be
considered when sighting the detector. The unit
is not recommended for mounting on metal
clad buildings in direct sun as excessive heat
produces haze ripple which can produce false
activation's.
.
Floodlights also emit haze ripple. When
installing floodlights to provide movement
activated lighting, position the floodlights at
the side or above the detector. A minimum of
60cm ( 2 feet ) is recommended, provided the
detector is not in direct radiated heat from the
floodlight.
Once alignment is completed, check that the
vent hole of the front cover is positioned at the
bottom. Also ensure that both sides of the outer
casing are engaged before pressing the cover
firmly to securely locate it.
