Mossa WL PIR Black
MODEL: 89437
INTRODUCTION
The bulkhead light incorporates a PIR (Passive Infra Red) sensing
device which continuously scans a preset operating zone and immedi
-
ately switches the lamp on when it detects movement in that area.
This means that whenever movement is detected within the range of
the sensor the lamp will switch on automatically to illuminate
pathways, steps, patios, porches, or whatever area you have selected
to light for reasons of safety, convenience or security.
While there is movement within range of the unit the lamp will
remain on.
WHILE TO FIT YOUR LIGHT
To achieve best results, we suggest you take into account the follo
-
wing points:
■
Ideally the bulkhead light should be
mounted 1.8 to 2.5 meters (6 to 8ft)
above the area to be scanned (refer
Fig.1A).
■
To avoid damage to unit-do not aim the
sensor towards the sun.
■
To avoid nuisance triggering, the sensor
should be directed away from heat sour
-
ces such as barbecues, Air-conditioners, other outside lighting,
moving cars and flue vents.
■
To avoid nuisance triggering, keeping away from the area of strong
electromagnetic disturbance.
■
Do not aim towards reflective surfaces such as smooth white
walls, swimming pools, etc. The PIR Sensor scanning specifications
(approximately 10 meters at approx. 110°--horizontal) may vary
slightly depending on the mounting height and location. The
detection range of the unit may also alter with temperature
change. Before selecting a place to install your
global lamp you should note that movement
across the scan area is more effective
than movement directly toward or away from
the sensor (refer Fig.1B). If movement is made
walking directly towards or away from the
sensor and not across, the apparent detection
range will be substantially reduced. (refer Fig. 1C)
