INTRODUCTION
The Pearl Detector is an outdoor motion detector with dual
detection technology and anti-masking that uses PIR and
microwave detection.
Both sensors must trigger to cause the detector to alarm
ensuring precise and reliable presence detection. The
detector has three N/C outputs for alarm, masking and
tamper triggering.
QUICK INSTALLATION
1.
Mount the detector following the instructions in
sections “Mounting the Unit” and “Detector Placement
and Beam Pattern”.
2.
Power the unit and ensure switch 1 is set to ON. The
unit will flash for two minutes during this time. Fit the
front cover on the unit and when the unit has finished
flashing it will be ready for walk testing.
MOUNTING THE UNIT
During installation, protect the electronics against water as
trapped moisture can affect or damage the unit.
BASIC INSTALLATION, BEAM OUTWARD FROM
SURFACE
(see figures 2,3,11,13)
1.
Use drilling template to locate the two mounting holes
(A figure 2).
2.
Next feed the cable through rear or side knock-outs
and then fix to the wall (B & C figure 2).
INSTALLATION WITH T-BRACKET ASSEMBLY, BEAM
ACROSS SURFACE
(see figures 4,5,12,14)
1.
Use drilling template to locate the four mounting
holes (A figure 4).
2.
Next feed the cable through rear or side knock-outs (
B figure 4) and out through cable access point. Fix to
the wall and then secure the blanking plate onto the
unused side of the T-bracket (figure 5,15).
FRONT ASSEMBLY (see figure 6-10)
1.
Feed cable through grommet. Clip middle section
shown into lower part of back section (figure 8) push
back until flat to wall. Cut and wire the cable into the
terminal blocks (figure 6,7)
2.
Push the bottom of the front cover into clip on the
middle section and rotate back flat to the wall (figure
8). Secure by tightening the screw in access hole.
Finally push fit screw cover.
3.
To access the unit once installed first lever off the
screw cover (see figure 9). Unscrew the screw in the
access hole. Next reverse steps shown in (figure 8)
or to remove from the wall use provided clip to lever
off the wall mounting (see figure 10).
DETECTOR PLACEMENT AND BEAM PATTERN
(see
figure 12 -15)
The detector uses microwave and infrared sensing to
determine motion detection. The optimum position of the
detector should be chosen to detect an intruder crossing
the beam pattern (figure 13), and to avoid traffic from roads
and paths (figure 14).
For applications where the T-bracket is used ensure the
angle of the detector is pointing 2° away from the building
(figure 15).
The detector should be at an optimum height of 2-2.5m.
Secure the detector to a wall or solid fixture.
Two detectors must not be fitted back to back on the
T-bracket. A minimum space of 2 metres must be left
between detectors.
PROGRAMMING
The detector can be programmed with different range
and sensitivity options and also LED indication. This can
be done by changing the four DIP switch settings on the
detector PCB (see figure 6). The range can be set to 3, 6, 9
or 12m and the sensitivity can be changed to high or low.
WALK TEST
Set the LED Indication to Enabled (figure 6). On power up
the LED will flash red and green alternately for 2 minutes.
The detector will then indicate an alarm condition with a
red LED.
The alarm detection will flash red for 1s with an interval of
5s between detections when LED indication is ON.
The masking condition is indicated with a continuous green
led indication when LED indication is ON.
MASKING OUTPUT
A masking event will be triggered after 60s of masking of
the lens. The masking output will be cleared by removing
the masking object. To re-calibrate the masking reset
power to the device or change a DIP setting and replace
the cover and allow to calibrate.
