INTRODUCTION
The mini Opal is an attractively styled, 30 metre Passive
Infrared (PIR) detector that works with GJD security
lighting controllers. The mini Opal has additional
advanced PIR features as follows:
•
Sensor mounted white-light filter to stabilise
detections on sunny days
•
Dual tamper switches for cover and wall-mount
tamper detection
•
Zone blanking using vertical curtains and horizontal
foil for precise area coverage
•
±90° horizontal and ±45° vertical aim adjustment
•
Conformally coated electronics for enhanced UV and
moisture resilience
•
Attractive, modern styling with a protective cover to
disguise sensor direction
WARNING
•
NYLON WASHERS PROVIDED MUST BE USED
WITH SCREWS
•
ENSURE CABLE ENTRY AND SCREW HOLES
ARE SEALED WITH WATER BASED SEALANT
•
DO NOT USE SILICONE BASED SEALANT
FIELD OF VIEW
The mini Opal has 10 Fresnel lenses that focus areas
onto the receptor. The 10 lens areas give 10 fields of view
as follows: 5 long-range (lenses 0 to 4) and 5 medium- to
short range (lenses 5 to 9). Movement between fields
produces a stronger response than movement towards
or away from the sensor in the same field. The 10 lenses
monitor the area in front of the sensor as shown in the
figure..
