Movement Detector GJD 350
Introduction
• A CCTV event trigger utilising two independent passive infrared detectors combined in a
T05 package. Both sensors have to trigger before the detector signals an alarm. This high
precision very reliable presence detector has been designed for use within CCTV installations.
Programmable parameters include three normally open or normally closed configurations
for the two CCTV volt free output relays, as well as a changeover timer, a pulse count feature
and a choice of detection ranges from 25 to 50 metres.
• In addition there are two switched negative outputs. The 'A' output gives a single 400ms
trigger every time the detector activates and is generally used in conjunction with the GJD
lighting controllers to give 24-hour visual and audible alarm indication. The 'S' output is a
photocell-controlled signal giving a fixed 60-second trigger on activation.
Additionally independent front and rear tamper circuits are combined to provide a volt free
tamper alarm contact. The flexibility of the various outputs and timers allows the
to be used in multiple situations without the need for any further customised
equipment.
• The integral dual axis tilt sensor allows 180° of pan and 90° 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 zinc alloy 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
design gives a neat and professional appearance with no visible
indication of the orientation of the detector head, and totally hides the wiring.

Installation & Set Up Guide
Stage 1 – Mounting the unit
- 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 using the allen key
provided. The cover hinges from the top and lifts out of the location slot.
See fig. 3.

3) Feed standard 12 core alarm cable into the cable entry; bare the wires and
connect to the removable 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 microswitch
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) Always ensure when replacing the electronics module that the LED is facing
forward so as to ensure correct alignment of the beam pattern. (Refer section
titled "Beam Alignment")
5) When the detector has been aligned to suit the installation, replace the front cover
and lock as shown.
