D-TECT Pet Immune
GJD370/371/372 Motion Detector

INTRODUCTION

An event trigger utilising two independent passive infrared
detectors and a microwave sensor. Both PIR sensors and
the microwave have to trigger before the detector signals
an alarm. The high precision, very reliable presence
detector has been designed for use within monitored
installations and will alarm if tampered by masking.
The integral dual axis tilt sensor allows 180° of pan and
30° tilt. This increases the speed of the outdoor installation
and provides incredibly accurate aiming of the detection
pattern. The electronics module is acrylic coated for
additional component stability. It is encased in a vandal-
resistant high impact ABS housing with a UV stabilised
translucent front cover ensuring the sensor is impervious
to and unaffected by weather conditions. Additionally the
combination of precision electronics, digital white light filter
and double shielding eliminates false alarms from the sun
and other visible light sources.
The Pet Immune design gives a neat and professional
appearance with no visible indication of the orientation of
the detector head, and totally hides the wiring.
QUICK INSTALLATION GUIDE
Apply supply voltage to the unit, the amber led flashes 10
times, then the blue LED flashes 3 times.
The detector takes approximately 2-3 minutes to settle. The
walk test led is enabled for 5 minutes after power is applied
THE FRONT COVER MUST BE FITTED WHEN WALK
TESTING
FACTORY SETTINGS ARE:
1 RANGE 15 METRES
2 PULSE COUNT 1
3 LED OFF
When enabled the D-TECT Pet Immune has four LED
indicators.
Green – Bottom PIR
Red – Top PIR
Blue - Alarm output, both PIRs and microwave detection
Amber - Anti-Mask detection

ANTI-MASKING CIRCUIT

The cover must be fitted before applying power to the
detector.
During the first 10 seconds after power has been
connected, the amber LED flashes and the anti-masking
circuit starts to self-calibrate. The amber LED indicates
when the detector is covered, but the relay contacts do not
operate until the unit has been covered for 60 seconds.

SEQUENCE FOR CORRECT AM OPERATION

1. Make connection and replace cover.
2. Apply 12 volts power. Amber LED Flashes 10 times - self
calibration completed.
3. Cover detector for 60 seconds. When anti-mask
detection is continuous for 60 seconds the normally closed
relay will open until anti-mask detection is cleared.

STAGE 1 - Mounting the unit

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
To reduce the possibility of the microwave circuit being
affected it is recommended to leave a minimum space of
3 metres between D-TECT Pet Immune sensors when
mounted alongside each other. When facing each other
a minimum space of 15 metres is recommended. It is
possible to mount the units back to back however when
detectors are mounted in close proximity to one another it
is advisable to carry out a walk test to ensure that external
objects are not influencing the microwave circuit.
- During installation the electronics must be protected
against water, as trapped moisture can affect or damage
the unit.
1. Using the template provided drill the wall to accept the
two fixing screws, the cable entry and the tamper cup (if
used). See fig 1 and 2.
Note: We recommend using the tamper cup on uneven wall
surfaces.
2. Remove the cover assembly by loosening the locking
screw. The cover hinges from the top and lifts out of the
location slot. See fig 3.
3. Feed standard 8 core alarm cable into the cable entry;
bare the wires and connect to the terminal block as shown
in fig 7. Screw the unit to the wall ensuring that the tamper
pin is correctly located and that the tamper switch
is closed. See fig 4 and 5. To aid installation, two spare
tamper feet are provided. One is 1mm longer and the other
is 2mm longer than the tamper foot originally fitted. The
tamper foot is a push fit and can be removed by carefully
pulling it from the pin. See fig 2.
4.When the detector has been aligned to suit the
installation, replace the front cover and lock as shown. See
fig 6.
