INTRODUCTION
The D-TECT 50 IP is a highly sophisticated, but user
friendly, IP-based motion detection device and alarm trigger
that harnesses the power of IP with PoE (Power over
Ethernet) connectivity, advanced signal processing, quad
pyro scanning and unique optical systems to provide stateof-the-art alarm capture.
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
During installation, protect the electronics against water, as
trapped moisture can affect or damage the unit.
1. Drill the wall to accept the xing screws, the cable
entry, and the tamper cup (if used). See Figures 1
and 2. A hole-drilling template is provided. Note: GJD
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 Figure 3.
3. Feed standard CAT5 cable into the cable entry. See
Figures 2, 4 & 5.
4. Screw the unit to the wall ensuring that the rear tamper
pin is correctly located and that the tamper micro switch
is closed. See Figure 6. To aid installation, two spare
tamper feet are provided. One is 1mm longer and the
other is 2mm longer than the tamper foot originally
tted. The tamper foot is a push t and can be removed
by carefully pulling it from the pin. See Figure 2.
5. When the detector is aligned, connected, and
programmed to suit the installation, replace the front
cover and lock as shown. See Figure 7.
CONNECTING THE UNIT
Fit the RJ45 plug to the cable and plug into the socket
on the top PCB. This must be done before the cable is
connected to the PoE switch.
There are 2 volt free relay contacts on the top PCB for
connecting auxiliary equipment. These are programmable
in the web browser set-up page.
BEAM ALIGNMENT
The PIR circuitry detects changes in heat and movement in
the beam pattern; therefore items such as trees, shrubs,
ponds, boiler ues, and animals should be considered
when positioning the detector.
The detector is tted with a mirror on the pyro sensor to
provide a detection zone directly underneath the detector.
Note: The maximum mounting height is 3 metres when
utilising the creep detection zone.
When using the pet immune conguration the mirror should
be removed.
Note: The PIR sensor is more sensitive to movement
across the beams, and less sensitive to movement
directly towards or away from the beams.
When coverage exceeds the desired detection area, adjust
the module as required to avoid unwanted detection.
Figures 14 and 8 illustrates alignment recommendations for
when the detector is mounted close to a wall.
The alignment shown in Figure 14 is not recommended. If
the detector module is orientated at an angle of 90° to the
perimeter, the mounting wall may cut off short and medium
range beams. The long range beam will still detect an
intruder, however the wall can cause false alarms when
heated by sunlight.
Figure 8 shows the recommended alignment. The detector
module is orientated at a 55° angle to the perimeter. As a
result, short and medium range beams are parallel to the
perimeter, but the detection range along the perimeter is
reduced to 25 metres.
PROGRAMMING
There are 2 different ways of programming the detection
range, pulse count and LED setting.
1. Using the programming button, programming LED and
programming chart below.
2. Via the web based interface. The user can individually
program a number of congurable settings, as
illustrated in the programming chart.

To change any of the D-TECT 50 IP settings:
1. Press the program button, as shown in gure 4, for
the number of the Option to be changed, i.e. once for
range, twice for pulse count, three times for LED.
2. Wait until the blue LED indicator goes off (typically four
seconds).
3. The indicator will then ash out the existing settings.
4. To change the settings for that option, press the
program button the number of times for the required
new setting.
5. The indicator blinks twice and the changes are stored
in the D-TECT 50 IP’s non volatile memory.
Example: To change the LED setting from OFF to ON:
1. Press the program button three times.
2. Wait until the blue LED indicator goes off (typically four
seconds).
3. The indicator will then ash once, indicating the current
LED setting is OFF.
4. Press the program button twice to change the setting
to ON.
5. The indicator blinks twice and the changes are stored
in the D-TECT 50 IP ’s non-volatile memory.
PROGRAMMING OPTIONS DEFINITIONS
Pulse Count
This is the number of times the unit has to detect on both of
its sensors before signalling an output.
LED
LED Off – LED disabled.
LED On – LED signals a detection
Relay outputs
Output 1 and output 2
These are magnetically immune volt free relay contacts
used to trigger alarm inputs on connected equipment.
The contacts are rated at a maximum of 24V AC/DC @
50mA.
The contact operating timer can be adjusted in the web
based user interface.
WALK TEST
In walk test mode, the detection LED option is set to ON,
and the pulse count option is set to 1.
1. The detection LED lights each time the D-TECT 50 IP
detects your presence
2. To enter the walk test mode, press the programming
button once. The detection LED is enabled and pulse
count 1 is automatically selected. Alternatively, the
walk test mode can be entered via the web based user
interface. The unit can then be aligned.
3. The test mode ends automatically ve minutes after the
last activation. Alternatively, press the program button
three times, to cancel the walk test mode.
Note: When you conduct a walk test, make sure that
the front cover is in place. Do not conduct walk tests
with the cover removed.
The range of the detector increases without the protective
front cover. Therefore the front cover must be tted to
establish the correct beam pattern. Use programming chart
to adjust the range as necessary. Pan and tilt the lens
module over the eld of view to obtain the correct coverage
area.
